Brief Summary of Minutes of Annual Meeting

Brief Summary of Minutes of Annual Meeting

In Attendance: Larry Cihacek, Anna Cates, Dan Olk, Michael Castel, Julie Grossman, Jango Bhadha, Carmen Ugarte 

1) Topics/proposals of interest to the committee

• Potential ideas to work on a review paper (i) that deals with carbon related research, past, present, and future directions; (ii) a methods paper that highlights the strengths and weaknesses of carbon metrics; (iii) critique on methods and approaches used for quantification and enrollment in C markets.
• Proposals to organize a symposium at the 2023 tri-societies meeting. Topics to consider relate to C markets, sequestration, and the metrics that the private and public sectors are using.
  There are concerns that the proposed symposium might overlap with sessions on this topic that were available at the 2022 tri societies program: 1) 135 - Symposium--CrossDiv--the Future of Carbon and Ecosystem Services Markets: Gaining Perspective from Producers, Policymakers, Industry Members, Scientists, and Non-Profit Groups. 2) 325 - Putting Carbon Back Where It Came from Oral I. 3) 211 - Symposium--Special Session--Complex Science of Soil Health, Food and Nutritional Security, and Climate Change

• Proposal to promote student interaction by sponsoring two sessions that would look like a symposium in the morning and lighting talks + poster session in the afternoon. This creates networking opportunities for students.

2) Proposals to re-engage and recruit new members 

• Onboarding new members is a priority. Some state reps have retired or as less active. There are suggestions to involve members from disciplines that overlap with foundational work on soil organic matter.
• Challenge - Some of the current members are on numerous committees and so difficult to commit time to NCERA 59.

3) Format for the 2023 meeting

• For 2023, the committee is eager to (i) return to in-person meetings (w virtual option) in Belle Glade, Florida; (ii) organize a symposium at the tri-societies conference.
  A proposal for dates will be sent out for voting.
• State reports need to be submitted in the next 60 days. Please use the attached template to prepare your state reports and send them to Carmen by December 5^th.

FL:  
Cultivating flooded rice in the summer as a rotation crop has shown to reduce phosphorus loads in farm canals, and also shown to improve soil quality. We have been successful in taking our research and findings beyond peer-review publications and reporting. Over the year we highlight our findings at extension events, such as field days, and open-houses, and public social events such as state fairs so that we can engage our clientele in topics related to soil health and sustainability within the region.

IL:  
We have maintained field and laboratory research in collaboration with researchers at other land grant institutions, Argonne National Lab, the USDA ARS, and NRCS Soil Survey Lab.  The first Organic Research Plots on the University of Illinois campus were certified in 2022.

MN:
The Cates lab collected on-farm soil health and soil organic and inorganic carbon data related to four graduate student projects, which they are in the midst of analyzing and writing up. Relative to assessments of soil organic matter, one student in Cates’ lab plans to study extraction efficiency of ACE protein protocol in high pH high clay soils.

The Grossman lab continues two ongoing projects, one to better understand the nutrient cycling and soil health impacts of summer-planted cover crops in rotation with cool season vegetables such as broccoli and lettuce, and a second to optimize planting and termination dates for cover crop legumes in high tunnels in rotation with high value summer crops such as sweet peppers. Results of the summer cover cropping project are showing cover crops play a valuable role in capturing nitrogen that may otherwise be lost to the environment in fallow periods when no crops are present, and then later contribute this nitrogen when vegetable crops might be able to better utilize it. We are also learning that in high tunnel environments, earlier planted fall cover crops may contribute more to spring soil N, despite the trade off with pepper productivity.

The Gutknecht lab began one project (see leveraged funding) and continues multiple other projects to understand how perennial and continuous living cover cropping systems may improve the ecological functioning of agricultural ecosystems. Three graduate students on related projects are completing thesis revisions, with manuscripts in final preparation or submission. In 2022 the first year of climate change treatments were implemented in a large trial including multiple annual and perennial cropping systems, with the second year of treatment in 2023.

Gutknecht, Grossman, and Cates also collaborate by being on each other’s student committees, and through collaborative research projects, creating regular conversation about soil carbon and nitrogen dynamics in agricultural systems.

ND:  
We have demonstrated that in the cooler, drier climate of the Northern Great Plains, post-harvest crop residue left in the field tends to accumulate due to slow decomposition. We have also demonstrated that the wide C:N ratio of the residues contain low amounts of N so that during the decomposition process microbes responsible for the decomposition immobilize the N in the residue as well as soil N to effect the decomposition. We are now trying to utilize residues of potential low C:N cover crops, especially with shorter season grain crops, to offset the effects of the N immobilization and reducing the N fertilizer requirements for subsequent crops. This can reduce production costs for the farmer and also reduce the environmental impacts of the added fertilizers.

Although we are early in the study, increasing the pH of very acid soils can reduce the effects of soluble Al³⁺ on crop root development and growth thereby improving plant productivity and more efficient use of soil nutrients and water in a semi-arid environment. Low-rate liming appears to show promise for mitigating very acid soils in order to allow the farmer to more actively manage soil acidity using other means (crop/variety selection, fertilizer type and rate adjustments, etc.). this work is continuing through 2022 and into 2023.

TN:
