Please see attached file below for NC1178's full annual report with easier to view formatting, especially the table.
The meeting was hosted and presided over by Kristopher Osterloh, South Dakota State University. Presentations were delivered according to the meeting agenda, with representatives providing updates on research activities, major findings, publications, and outreach accomplishments from their respective institutions. The presentations generated engaging questions and productive discussion among project members.
During the business meeting, the group reviewed the progress of NC-1178 and discussed plans for future collaborative activities. Major topics included the proposed symposium at the 2026 ASA-CSSA-SSSA Annual Meeting in Portland (led by Larry Cihacek), the special-topic journal issue (led by Kristopher Osterloh), and opportunities for joint manuscripts and cross-institutional research (led by Humberto Blanco). Members discussed potential article topics, authorship, timelines, and strategies for avoiding overlap. The group agreed to continue using a shared document to coordinate proposed topics and identify opportunities for synthesis papers and meta-analyses. The remaining presentations continued according to the agenda and were followed by additional discussion and feedback. Members exchanged ideas about future research priorities, collaborative funding opportunities, and approaches for increasing the visibility and impact of the project’s work. The meeting concluded with a group dinner/networking event. The group participated in a field tour of a South Dakoda State University research farm on the second day of the annual meeting (06/26/2026). The tour highlighted ongoing research related to soil carbon, soil health, conservation management, and agroecosystem services and included presentations from faculty, research staff, graduate students, and/or local agricultural partners. The tour provided participants with an opportunity to observe current experiments and discuss their practical and regional applications. The next annual meeting of the NC-1178 group will be hosted by Yichao Rui at Purdue University in West Lafayette, Indiana in June 2027.
Accomplishments
<h1>Accomplishments</h1><br />
<p><em><span style="text-decoration: underline;">Research Activities</span></em><span style="text-decoration: underline;">:</span> During the 2025–2026 reporting year, NC-1178 committee members reported dozens of peer-reviewed publications and numerous scientific and Extension presentations related to soil carbon, soil health, and the effects of agricultural management on ecosystem services. The committee investigated a wide range of practices, including reduced tillage, crop-residue management, cover crops, crop rotations, organic amendments, nitrogen and irrigation management, prescribed burning, and adaptive grazing. This work encompassed diverse environmental and production systems, including row crops, rice, vineyards, forests, rangelands, pastures, and organic farming systems across multiple U.S. regions (Table 1). Team members advanced a shared goal of developing conservation production systems that improve soil carbon storage, nutrient and water-use efficiency, agricultural productivity, and climate resilience. The committee’s broad interdisciplinary expertise supported research collaboration, student training, stakeholder engagement, and the exchange of scientific guidance across institutions. The team met its 2025–2026 milestones and will continue implementing the planned research. Members also continued developing collaborative synthesis papers, a potential special-topic journal issue, and a symposium for the 2026 ASA-CSSA-SSSA Annual Meeting to increase the visibility and public accessibility of NC-1178 research.</p><br />

<p>The research team used the Agricultural Policy/Environmental eXtender (APEX) model to assess the long-term effects of regenerative agricultural practices in the Double Mountain Fork Brazos Watershed in the Texas High Plains. The evaluated practices included no-tillage, no-tillage with a rye cover crop, and no-tillage with cotton–sorghum or cotton–winter wheat–fallow rotations.</p><br />
<p> </p><br />
<p>The study quantified how these regenerative practices affected surface runoff, sediment loss, nitrogen and phosphorus loading, and cotton yield under both irrigated and rainfed conditions. The analysis also evaluated how watershed-scale outcomes changed with the proportion of cropland managed using regenerative practices.</p><br />
<p> </p><br />
<p>Modeling results showed that regenerative practices substantially reduced runoff and sediment and nutrient losses compared with conventional tillage. Benefits increased as the proportion of cropland under regenerative management increased, while cotton yields were not significantly affected.</p><br />

<p>The research team completed a 31-year assessment of soil carbon dynamics by resampling 11 paired cropland and undisturbed grassland sites originally sampled in 1991–1992 and again in 2010 and 2023. The study quantified changes in total soil carbon, soil organic carbon, and soil inorganic carbon under semiarid conditions and evaluated the effects of long-term conversion from crop–fallow systems to continuous no-till production.</p><br />
<p> </p><br />
<p>A complementary study examined acid phosphatase activity in the corn phase of two 36-year crop-rotation systems. The research evaluated the effects of conventional tillage versus no-till, nitrogen fertilization, and repeated manure applications on phosphatase activity, soil-test phosphorus, and soil health. Additional research on the effects of tillage on phosphorus stratification is underway.</p><br />
<p> </p><br />
<p>The team also investigated how soil carbon availability and microbial nutrient limitation influence suppression of potato common scab. The study evaluated relationships among carbon inputs, microbial community structure, microbial physiology, carbon-to-nitrogen balance, biogeochemical cycling, and disease severity. The results showed that increasing soil carbon alone did not consistently suppress disease; effective suppression occurred only when microbial communities shifted toward relative nitrogen limitation.</p><br />

<p>The research team evaluated how prescribed burning affects forest structure, plant productivity, belowground carbon allocation, root dynamics, microbial respiration, and annual soil carbon balance in mature shortleaf and loblolly pine forests. The work compared unburned stands with stands receiving annual, biennial, or intermittent prescribed fire and quantified the decomposition of coarse roots relative to stemwood as potential long-term soil carbon inputs.</p><br />
<p>The team used isotopic measurements to investigate how recently assimilated plant carbon is allocated among biomass production, respiration, nonstructural carbon storage, root exudation, and soil microbial processes. The research examined diurnal and seasonal controls on carbon transfer from leaves to roots and soil, with particular attention to water availability, temperature, plant sink strength, and the relative responses of root and heterotrophic respiration.</p><br />
<p>The research also compared adaptive multipaddock grazing with conventional intensive grazing across paired rangeland sites. Measurements included grazing-rest periods, standing biomass, net primary production, manure inputs, soil moisture, belowground carbon allocation, microbial respiration, and annual soil carbon balance. The study assessed whether longer recovery periods under adaptive grazing improve vegetation growth, belowground carbon inputs, microbial activity, and soil carbon outcomes.</p><br />

<p>The research team conducted a two-year field study at 13 locations to evaluate early-season soil nitrogen supply and subsequent nitrogen nutrition in corn. Treatments included nitrogen applications of 75, 150, or 225 lb N/acre at the V4 growth stage, followed by either 0 or 75 lb N/acre as a late rescue application at the VT/R1 stage.</p><br />
<p>The study quantified corn yield, ear-leaf nitrogen status, grain nitrogen concentration, kernel number, and kernel weight to determine when very late nitrogen applications could alleviate crop nitrogen stress. It also examined how soil organic matter and fertilizer nitrogen interact to support corn productivity across environments with site-average yields ranging from approximately 90 to 260 bu/acre.</p><br />
<p>The results showed a low probability of benefit from VT/R1 nitrogen application when soil and fertilizer nitrogen supplies were adequate. However, when nitrogen stress occurred, the late rescue application prevented approximately 70–90% of the potential yield loss, primarily by increasing kernel size. The research also demonstrated that soil organic matter contributes to soil nitrogen-supply resilience and provides greater flexibility in the timing of corn nitrogen management.</p><br />

<p>The research team evaluated conservation management practices for improving soil organic matter, nutrient cycling, microbial diversity, and crop production in sandy agricultural soils. The studies examined grass, legume, and mixed-species cover crops, as well as manure compost, to determine how their chemical composition and physical characteristics influence soil carbon and nitrogen processes.</p><br />
<p>The team measured gaseous nitrogen losses, soil water-filled pore space, rainfall, and fertilizer effects under different cover-crop systems. The research also quantified root-derived carbon inputs and turnover rates from grass and legume cover crops and evaluated changes in microbial communities and functional groups associated with carbon and nitrogen cycling.</p><br />
<p>Results showed that rainfall and soil moisture conditions were stronger drivers of nitrogen losses than fertilization, with losses increasing rapidly above a water-filled pore-space threshold. Legume-derived root carbon turned over more rapidly than grass-derived carbon, while manure compost and different cover-crop combinations altered microbial communities through distinct mechanisms. These findings support the development of soil-management guidelines that improve nutrient-use efficiency, soil health, and agronomic productivity in sandy soils.</p><br />

<p>The research team compared continuous flooding with furrow-irrigated rice using tailwater recirculation to determine how irrigation management affects greenhouse gas emissions, evapotranspiration, crop water use, and rice productivity. Eddy covariance measurements, gas sampling, and crop assessments were used to quantify carbon dioxide, methane, and nitrous oxide emissions, seasonal evapotranspiration, water-use efficiency, biomass production, and grain yield.</p><br />
<p>The study evaluated whether alternate wetting and drying created by tailwater recirculation could reduce crop water demand and the global warming potential of rice production. Tailwater recirculation reduced seasonal evapotranspiration by approximately 19% and improved water-use efficiency by 18% without reducing rice yield. However, increased nitrous oxide emissions from aerobic portions of the furrow-irrigated system offset reductions in methane emissions, resulting in global warming potential comparable to that of continuously flooded rice.</p><br />
<p>The team also conducted on-farm research evaluating polysulfate fertilizer as a strategy for reducing methane production in flooded rice. Polysulfate application reduced estimated methane emissions from 17.1 to 3.4 kg CH₄/ha over a 53-day flooding period, potentially by stimulating sulfate-reducing microorganisms that compete with methanogens for acetate. These studies provide information for improving water conservation while identifying additional management practices needed to reduce greenhouse gas emissions from rice production.</p><br />

<p>The research team evaluated how crop selection, nitrogen fertilization, and residue production affect soil carbon sequestration in the warm, humid subtropical environment of southeastern Texas. Field studies focused on biomass sorghum and energycane, examining how cultivar selection and nitrogen-management rates influence biomass production, residue inputs, soil disturbance, and the potential for long-term soil carbon accumulation.</p><br />
<p>The team investigated alternate wetting and drying irrigation strategies for reducing water use and methane emissions from rice production. Continuous flooding was compared with irrigation triggered when the water table declined to 15 or 30 cm below the soil surface. The study also compared hybrid and inbred rice cultivars and tested newly developed soil redox sensors for monitoring soil conditions. Moderate drying to 15 cm maintained yields comparable to continuous flooding, whereas drying to 30 cm reduced yield; the hybrid cultivar showed greater tolerance to water stress.</p><br />
<p>A greenhouse study evaluated zinc oxide nanoparticles, their transformation products, and conventional ionic zinc as nutrient sources for rice grown in clay soil. The research measured rice growth, root morphology, nutrient uptake, grain yield, and zinc-use efficiency. Conventional zinc sulfate produced the highest zinc uptake, increased grain yield by 19%, and achieved a zinc-use efficiency of 144.5, while zinc phosphate increased root surface area by 330% and root volume by 497% but provided less plant-available zinc.</p><br />

<p>During 2025-2026, the Purdue team led by Dr. Rui completed and published research on decade-long cereal rye cover cropping, demonstrating measurable improvements in soil carbon and physical properties. The team also published findings on soil organic matter persistence across soil depths and long-term cropping systems, contributing new knowledge about the mechanisms controlling carbon stabilization in agricultural soils.</p><br />
<p>Two complementary studies were completed on the belowground performance of short-stature maize. These studies evaluated how maize hybrid selection, soil type, and nitrogen fertilization affect root development, plant carbon allocation, root exudation, and root-derived carbon inputs. This research expanded interdisciplinary collaboration among soil scientists, crop physiologists, agronomists, and agricultural engineers.</p><br />
<p>The team also expanded the Indiana Organic Network into a statewide, farmer-engaged soil-health research platform. Soil-health assessments were completed across 91 organic field sites, and baseline measurements were established at newly developed resilient agriculture research sites across Purdue Agricultural Centers. Findings were shared with scientists, crop advisers, farmers, and other stakeholders through peer-reviewed publications, professional conferences, Extension programs, and producer field days.</p><br />

<p>The research team completed the second year and began the third year of a field experiment evaluating drought-tolerant summer cover crops in New England silt loam soil. The study compared sunn hemp, forage soybean, pearl millet, teff, and selected biculture mixtures under tilled and no-till management to determine how differences in plant biochemistry and root architecture affect soil carbon and nitrogen availability and the productivity of a subsequent fall turnip crop.</p><br />
<p>The team collected soil, root, shoot, and root-exudate samples following the summer cover crops, fall turnips, and winter rye. Plant materials were analyzed for carbon and nitrogen, while soils were collected for biological, chemical, and physical soil-health measurements, including enzyme activity, respiration, microbial biomass, soil organic carbon and nitrogen, water-holding capacity, aggregate stability, compaction, and bulk density. A root- and shoot-decomposition study is also being incorporated to evaluate the availability of cover-crop carbon and nitrogen to the following cash crop.</p><br />
<p>Initial results showed that pearl millet produced consistently high aboveground and belowground biomass and provided the greatest improvement in soil water-holding capacity. Teff, sunn hemp, and their bicultures produced substantial dry biomass and may contribute strongly to soil organic matter formation and nutrient cycling. The project also trained one Ph.D. student and five undergraduate researchers in field and laboratory methods for assessing soil and plant nutrients.</p><br />

<p>The research team applied vermifiltration-derived vermicompost across 10 commercial fields representing diverse crops in California and Washington. The study evaluated how this organic amendment affects soil health, microbial functioning, nutrient cycling, greenhouse gas emissions, and crop performance across annual and perennial production systems.</p><br />
<p>The team completed four-year field trials examining the effects of regenerative management on soil carbon, hydrological health, and crop yield in vineyards across California, Oregon, and Washington. Researchers also analyzed soil carbon fractions and physical properties in 28 Napa Valley vineyard blocks to assess how management history, tillage, grazing, organic amendments, and other regenerative practices influence soil health and microbial communities.</p><br />
<p>Additional field research compared compost and vermicompost materials for their effects on nitrogen cycling and processing-tomato productivity. The team also evaluated water-saving irrigation, compost safety, environmental contaminants, and multi-omics approaches for characterizing soil microbiomes. During the reporting period, the program produced 12 accepted peer-reviewed publications, submitted seven additional manuscripts, delivered 17 scientific presentations and four Extension presentations, and graduated four Ph.D. students and one M.S. student.</p><br />

<p>The research team investigated how agricultural management, soil mineralogy, and plant–microbe interactions affect the size, composition, accessibility, and nitrogen-supplying potential of soil organic matter. The work focused particularly on particulate organic matter and mineral-associated organic matter nitrogen across soils representing different geochemical characteristics and land-management histories.</p><br />
<p>The team conducted greenhouse experiments to determine how mycorrhizal fungi and root-associated fungal endophytes influence soil organic matter formation, mineral–organic associations, and crop nitrogen nutrition. Sequential chemical extractions were used to evaluate the potential mobilization of mineral-associated organic nitrogen by water and plant- and microbe-derived compounds. The results indicated that approximately 20% of mineral-associated organic nitrogen may be mobilizable and potentially available to plants and soil organisms.</p><br />
<p>The team also developed customized greenhouse growth chambers integrated with a dual carbon-isotope analyzer for <sup>13</sup>CO₂ labeling and tracing carbon movement through plant–soil systems. This research infrastructure supported studies of rhizosphere carbon dynamics and expanded institutional capacity for isotope-based research. During the reporting period, the project trained six graduate students and two undergraduate researchers in soil biogeochemistry, greenhouse experimentation, isotope tracing, and analytical methods.</p><br />

<p>The research team combined sampling from 22 producer-managed crop and pasture farms with multiyear field experiments to determine how land use and management affect soil organic carbon from the surface to a depth of 60 cm. The studies evaluated long-term no-till, crop rotations, cover crops, residue retention, organic amendments, and strategic grazing across three Tennessee Major Land Resource Areas while accounting for precipitation, vegetation, soil texture, and sampling depth.</p><br />
<p>The team examined how soil aggregates and the quality and placement of organic inputs regulate soil carbon, nitrogen, and overall soil health. Field and laboratory studies compared cover-crop sequences, poultry litter combined with soil amendments, different rates of wheat-straw return, and leaf and root residues under contrasting fertility conditions. Measurements included bulk and aggregate-associated carbon and nitrogen, microbial biomass, enzyme activity, microbial-community composition, soil quality indicators, and stable-isotope tracing of carbon transformations.</p><br />
<p>Additional studies evaluated microbial and soil-carbon responses to crop diversification, drought, mixed-species residues, and biodegradable microplastics. The research assessed fungal pathogens, arbuscular mycorrhizal fungi, carbon priming, mineral-associated organic carbon formation, and the decomposition of different biodegradable plastics. These integrated studies identified how soil depth, environmental conditions, residue quality, microbial seasonality, and emerging stressors influence soil carbon storage, nutrient retention, and agroecosystem resilience.</p><br />

<p>The research team continued a long-term field study evaluating the effects of corn-residue retention on crop productivity and soil properties at South Charleston and Hoytville, Ohio. Residue-retention rates ranged from 0% to 200%, and measurements included corn grain and stover yields, total biomass, harvest index, soil organic carbon stocks, aggregate stability, bulk density, and soil water retention at depths of 0–10 and 10–20 cm.</p><br />
<p>The study compared responses in the silt loam soil at South Charleston with those in the clayey soil at Hoytville. Grain and stover yields were higher at Hoytville, largely because its clayey soil retained more water and nutrients, but crop yields and harvest index generally did not differ among residue treatments. These results indicate that approximately 25–33% of corn residue could potentially be removed for other uses without an immediate yield penalty.</p><br />
<p>Although partial residue removal did not reduce short-term crop yield, retaining more residue generally increased surface-soil organic carbon and aggregate size. Average soil organic carbon stocks at 0–10 cm were approximately 42.2 Mg C/ha at Hoytville and 36.4 Mg C/ha at South Charleston. The findings demonstrate that residue removal decisions must balance short-term opportunities for residue use against possible long-term effects on soil carbon storage, soil health, water relations, and sustainable productivity.</p><br />

<p><em><span style="text-decoration: underline;">Outputs</span></em>: During the 2025–2026 reporting period, the NC-1178 team produced over 70 peer-reviewed publications and delivered more than 100 scientific and conference presentations. Members also conducted multiple Extension presentations, field days, workshops, and other stakeholder-engagement activities. These outputs communicated project findings to scientists, producers, agricultural advisers, conservation professionals, policymakers, and the public and met or exceeded the output expectations established in the project outline.</p><br />
<p><span style="text-decoration: underline;">Short-term outcomes</span>: Findings generated by the team demonstrate how land use and management practices can improve soil organic carbon, soil health, nutrient cycling, water-use efficiency, and agroecosystem resilience while maintaining crop productivity (Table 1). Results were disseminated through peer-reviewed and open-access publications, scientific conferences, Extension programs, field days, and direct engagement with producers. Major findings included: 1) conservation practices—including cover crops, reduced tillage, crop rotations, residue retention, organic amendments, and regenerative management—improved soil carbon and soil functions across diverse production systems (CA, IN, MA, OH, SC, TN, and TX); 2) irrigation, drainage, and nitrogen-management strategies influenced crop productivity, water-use efficiency, nutrient losses, and greenhouse gas emissions (KY, MS, and TX); 3) soil microbial communities and mineral-associated organic matter played important roles in carbon persistence, nutrient availability, disease suppression, and crop nitrogen nutrition (CA, IN, MA, ND, SC, TN, and TX); 4) prescribed burning and grazing intensity altered vegetation carbon allocation and microbial activity, although annual soil carbon responses were comparatively small or required longer periods to detect (TX); and 5) soil texture, depth, climate, residue quality, and management history strongly influenced soil carbon storage and should be considered when developing site-specific soil-health recommendations (CA, IN, MA, ND, OH, TN, and TX).</p><br />
<p><em><span style="text-decoration: underline;">Milestones</span></em>: The team completed major 2025–2026 milestones related to field and laboratory data collection, long-term site resampling, treatment evaluation, soil and plant analyses, modeling, and dissemination of findings. Several multiyear experiments reached important analytical or publication stages, and participants expanded research capacity through new instrumentation, student training, and producer-engaged research networks. The team also began coordinating collaborative synthesis manuscripts, a potential special-topic journal issue, and a symposium for the 2026 ASA-CSSA-SSSA Annual Meeting. These activities will integrate results across locations, increase the visibility of NC-1178 research, and support the project’s future milestones for collaboration, outreach, and scientific synthesis.</p><br />
<h1>Impacts</h1><br />
<p>The research accomplishments summarized in Tables 1 address the broader objectives of NC-1178 and demonstrate the value of the committee’s interdisciplinary and multistate structure. The committee brings together expertise in soil science, agronomy, hydrology, microbiology, biogeochemistry, crop production, forestry, and rangeland management. Research and Extension activities conducted across the United States generated scientific, environmental, economic, and societal benefits. Collectively, these findings provide a data-driven foundation for predicting how land use and management affect soil organic carbon, soil health, agricultural productivity, water quality, greenhouse gas emissions, and climate resilience across diverse environments.</p><br />
<p><em><span style="text-decoration: underline;">Demonstrating the importance of soil health</span></em>. Committee members demonstrated that healthy soils support crop productivity, nutrient cycling, water retention, disease suppression, and resilience to drought and other environmental stresses. Long-term cover cropping, reduced tillage, crop rotation, residue retention, organic amendments, and regenerative management generally improved soil carbon and biological or physical soil-health indicators. However, responses depended on soil texture, climate, drainage, land use, management history, and sampling depth. These findings emphasize the need for site-specific soil-health assessments rather than uniform recommendations.</p><br />
<p><em><span style="text-decoration: underline;">Highlighting the role of organic carbon in soil functions</span></em>. Soil organic carbon is fundamental to nutrient availability, aggregate stability, water relations, microbial activity, and long-term productivity. NC-1178 researchers demonstrated that soil carbon formation and persistence are controlled by interactions among plant carbon inputs, root traits, microbial processes, mineral associations, residue quality, and environmental conditions. Findings showed that mineral-associated organic matter can cycle more rapidly than previously recognized and may supply nitrogen to crops. The research also demonstrated that management practices affecting belowground carbon allocation do not always produce immediate changes in annual soil carbon balance, highlighting the importance of long-term studies.</p><br />
<p><em><span style="text-decoration: underline;">Promoting sustainable soil and crop management</span></em>. The project generated practical information for improving conservation and production systems. Regenerative practices were projected to reduce runoff by 29–57%, sediment loss by 38–58%, nitrogen loss by 48–81%, and phosphorus loss by 29–52% in a Texas watershed without significantly reducing cotton yield. Tailwater recirculation improved rice water-use efficiency by 18%, while polysulfate application reduced estimated methane emissions from flooded rice by approximately fivefold. Research also demonstrated that cover crops, crop residues, organic amendments, drainage, irrigation, and nitrogen-management strategies must be integrated with local soil and climatic conditions.</p><br />
<p><em><span style="text-decoration: underline;">Improving nutrient-use efficiency and environmental quality</span></em>. Research conducted by the committee improved understanding of how soil organic matter, fertilizer management, irrigation, microbial nutrient balance, and crop genetics affect nutrient availability and loss. Very late nitrogen application prevented approximately 70–90% of potential corn-yield loss when nitrogen stress occurred, while soil organic matter increased the resilience and timing flexibility of corn nitrogen supply. Other studies demonstrated that rainfall and soil water-filled pore space strongly regulated gaseous nitrogen losses and that managing carbon and nitrogen together may enhance microbial processes involved in suppressing soilborne diseases.</p><br />
<p><em><span style="text-decoration: underline;">Supporting climate-resilient agricultural and natural systems</span></em>. Studies in croplands, rice systems, vineyards, forests, pastures, and rangelands showed that climate-resilient management must consider water availability, soil depth, residue quality, plant species, and disturbance intensity. Prescribed burning and intensive grazing reduced belowground carbon allocation and microbial activity, although annual soil carbon responses were comparatively small. Adaptive grazing increased standing biomass, soil moisture, belowground carbon inputs, and microbial activity. These findings help land managers evaluate tradeoffs among productivity, carbon storage, greenhouse gas mitigation, and ecosystem resilience.</p><br />
<p><em><span style="text-decoration: underline;">Social and economic benefits to society</span></em>. Improved soil health, fertilizer-use efficiency, water conservation, and greenhouse gas management can reduce production costs while protecting soil, air, and water resources. The project’s findings support more efficient use of fertilizer and irrigation water, reduce nutrient and sediment losses, and provide producers with greater flexibility in managing crops under variable weather conditions. Training graduate and undergraduate students and engaging farmers, agricultural advisers, Extension educators, and conservation professionals also strengthened the workforce and expanded public access to research-based management information.</p><br />
