Brief Summary of Minutes of Annual Meeting

March 1, 2017

Reno, NV

Introductions and opening remarks: Cindy Smith was introduced as Phyllis’s replacement as IPNI coordination for the conference.

Administrative Update: Rich Koenig was absent so there was no administrative update.

Phyllis Pates gave the treasurer’s report. The registration is similar to past years and may by close to last year at 125-130. Jim W. noted that attendance has been good since moving to Reno. Estimated balance is about $20k. Some discussion around if this was the appropriate balance or if any of this could be used for other investments (e.g., student travel awards, poster board replacement, speakers). The thought was that the appropriate balance might be enough to cover a conference expenses if a storm or other event forced low participation. This topic should be on the agenda for the 2018 meeting.

Many states seeing fewer faculty work in soils and nutrient management and are finding challenges in recruiting students. Lots of retirements and/or people close to retirement. Concern for where new ag workers are coming from is real. Several states revisiting alfalfa credits, especially Utah which is finding the alfalfa credit recommendation is ridiculously low. Emphasis for Wyoming is student numbers as is Colorado State.

Industry: Western Ag 163 PRS probes projects around the world. Using probes in nitrogen bands treat with urease inhibitors. Agrium and Potash Corp are merging this summer. Some industry reduced earnings and losses in 2016. Generally speaking R&D are around ‘biostimulants’ for new product development. Food companies are pushing, even dictating, production practices that are deemed sustainable. Some third-party entities, e.g. field to market, are trying to develop more science-based metrics.  

2017 Conference: Jim Ippolito discussed this year’s conference. The agenda is pretty good. Two slots could be open with speakers Brook Dale and Charlie Sanchez being absent due to family emergency. A new section on “Flash and Dash” fast advertisements for graduate student posters will debut in 2017. Jim stated that the earlier planning is the better for getting speakers. Conversation occurred around the value of the proceedings and recruiting speakers. Many speakers don’t want to submit papers for reasons such as time and how much credit you get for submitting proceedings. The requirements for proceedings should be on the agenda for the 2018 meeting. Since the conference is in a new venue, we should note the benefits and disadvantages of the Silver Legacy compared to the Grand Sierra. Some discussion occurred around how to better advertise, especially with CCA lists. Past registrants are in the database to get notifications. We do advertise in ASA publications. Potentially contact Rebecca Polk in Madison to explore advertising options through the ASA networks.

Crops and Soils News: WERA committee typically contributes four articles per year. Eric Bremer has already written one for the winter 2017 issue; Bryan Hopkins volunteered for June; Bob Miller for September and Jay Norton for winter. Jim Walworth will send them information about style and coordination. Nat Dellavalle mentioned that most Crops and Soils rarely have information that is relevant to California, particularly on explaining the proper way to interpret base saturation on soil test reports. Nate and Jim W. might submit an article on this.

Executive Committee: Eric Bremer volunteered to be the incoming secretary. Olga Walsh will be the vice-chair and Troy Bauder the chair.

Location for 2018: Several options were presented. Decision: 2018 meeting in the central valley of California, specifically Fresno, with Nat Dellavalle as host. March 12 – 15, 2018. Many diverse agricultural tour options in the area.

Website: What do we want on the site – group business, search engine, links to programs? Reports to the project need to be on the site. Phyllis said that since the page is going to the main office in Atlanta, Cindy will have connections to more resources to make upgrades, improvements, etc. Need to get the .pdf’s prior to 2011 to move to IPNI. Currently these are somewhere online at OSU.

Conference venue: Some discussion around moving the conference to another city or location during the week. Ken Greer brought up the Pepper Mill in Reno as an alternate venue. It is less smoky and the casino side is separate. The question was raised as to how big we really want to be and most folks thought we are around the right size. Past evaluations suggest Reno is ok, but smoky, casino environment could be better.

Refund policy: Jim W. asked about our refund policy, particularly after the end of the registration period. Should this be a percentage or after the date of paying for the conference venue. The committee decided that refunds after the venue bills have been paid are not paid.

Accomplishments by objective

1)  Develop and/or improve nutrient recommendations for diverse cropping systems based on soil, water and plant analysis results and management strategies in the Western Region.

    a. Provide nutrient correlation and calibration data for crops in the region.

    b. Work toward uniformity of nutrient use recommendations for similar crop production systems in the region.

    c. Evaluate and apply new nutrient analytical and interpretive methodologies.

    d. Evaluate the efficacy of new fertilizers and formulations.

Individual projects across states dovetail, e.g. nitrogen credits after alfalfa, phosphorus application techniques…need process to mine big data across states. Pool resources to hire person to write NSF big-data project. For example, Bryan has recently done a meta-analyses on phosphorus studies that showed that many crops are not all that different. Discussion: can any one person in the group have the time to be project leader on such an effort? Topics that perhaps cross all state boundaries might start by focusing on a nutrient such as P, a crop such as alfalfa or a rotation.

2)  Promote effective use of soil, water, plant, manure and compost analytical information

    a. Integrate analytical test results into nutrient management software

    b. Maintain and update the Western States Soil Plant and Water Reference Methods Testing Manual

    c. Review status of soil/plant/water analysis Extension guides and summarize interpretive guidanced.

    d. Explore method for internet distribution of methods manual, analytical interpretation guides etc. Website would be for clientele outreach.

Had similar idea about the concept in group one. Potentially partnering with ARS with a work group. Develop online system to collect field level data from companies and growers to validate outputs. Also discussed and numerous labs testing soil health parameters. Develop manual standardizing methods, recommendations, interpretation and communication around soil health.

So how do we take action on this meta-data concept since it has been discussed many times over the years. Jonathan suggested phosphorus since Bryan Hopkins has already started a meta-analysis on P. Develop working group(s) and seek resources to start with one topic. Perhaps look for NIFA planning grant(s) for this concept. Could be a sabbatical project? We need a better membership list of expertise and topics of interests. Grant Cardon volunteered to develop a survey of our group to develop this list.

3) Provide education on the principles of soil-plant-animal-water system management and the tools and practices that lead to sustainable agricultural production

    a. Facilitate regional education among government agencies, private industry and universities through conferences, websites, extension publications, newsletters, and other appropriate media.

    b. Disseminate information within the Western Region to extension educators, private agencies (e.g., Certified Crop Advisors) and other interested parties (e.g., K-12 teachers) through conferences, training the trainer opportunities, and access to published interpretive materials.

    c. Conduct direct education to agricultural producers through conferences, grower meetings, and published interpretive materials.

Dellavalle Lab has developed classes to bridge gap between what learned in school and what the job is. Calibration, Saline Sodic Soils and Waters, and other topics. Relationships between soil analysis and fertilizer recs - sufficiency levels, cation ratios, base saturation, others. Consider making webinars and/or recordings for websites. Ask IPNI about hosting webinars. Also talk with NMSU about cost for recording. Website for recordings. Start with the base saturation/cation ratio/etc. Other topics include C:N ratios - materials you apply vs what is in the soil; Nutrient and salt management - particularly with organic amendments; How water moves in soils; Using hardware store test kits - Caitlin Youngquist, Nat Dellavalle - what works and what doesn’t (on farm testing);

Nutrient Digest - Jay Norton taking over as the editor, will use the guest editor approach.

Discussed that we have branding for the WERA 103 logo and should use it when putting out materials, etc. Joan Davenport will check on status of logo and possible next steps.
