WERA-103 Committee meeting opened with opening remarks by David Tarkalson, WERA-03 Committee Chair and committee member introductions. The following committee members were in attendance:
Troy Bauder, Alan Blaylock, Sebastian Braum, Eric Bremer, Joan Davenport, Marko Davinic, Jonathan Deenik, Nat Dellavalle, Jason Ellsworth, Robert Flynn, Tim Hartz, Donald Horneck, Jim Ippolito, Clain Jones, Richard Koenig, Rob Mikkelsen, Bob Miller, Amber Moore (Vice Chair), Galen Mooso (Secretary), Dan Nelson, Stu Pettygrove, Dan Sullivan, Olga Walsh, Jim Walworth and Greg Binford (Visitor).
The following WERA-103 business items were discussed:
- Galen Mooso, Secretary reported that all of the state reports except for Utah and Wyoming had been received and were printed for committee members and distributed to committee members in attendance.
- Phyllis Pates was introduced as meeting site coordinator. Pre-registrations for 2013 Western Nutrient Management Conference (WNMC) were up for this conference compared to 2 years ago with 120 participants pre-registering. University attendance was about the same but industry participation was up with most of the increase coming from California. A copy of the WERA-103 financial statement with a proposed 2013 budget was provided. The 2011 ending balance was $11,465. The estimated revenue generated from the 2013 WNMC was estimated to be $2350. Logistics of the conference were discussed. A group of students from Fresno State University were in route with the poster boards for the poster session. Laptop computers and projector logistics for the sessions were finalized. It was suggested that because we will have two screens available that we should use both screens for the general session.
- Stu Pettygrove, conference Chair, discussed some last minute details regarding the conference. Session Chairs are Alan Blaylock, David Tarkalson, Troy Bauder, Rob Mikkelsen and Jason Ellsworth. There are 32 presentations presented by 30 speakers and 19 posters on the conference agenda. Eight of the posters will be presented by students and will be in a student competition with cash prizes being presented during the luncheon on Thursday. Cash award money is provided by industry partners. CCA CEU credits will be available for each session with signup sheets are already prepared. Stu Pettygrove was thanked for putting together an outstanding conference.
Rich Koenig WERA-103 Administrative Advisor gave an update to the committee. Rich explained that he represents the western region Experiment Station and Extension Directors. One of his responsibilities is to make sure funds are being spent wisely. He updated the committee on how experiment station and extension funds are being reduced. He also reminded the committee that WERA-103 committee will need to resubmit a proposal in 2015 for continued existence. He recommended that a sub-committee be appointed at the 2014 committee meeting to prepare the resubmission necessary for continuing WERA-103 for another 5 years. He commended the committee for putting together an outstanding program for the 2013 WNMC which is the flagship activity of the committee. He said that he had been part of the committee since 1995. He said that he attended the very first WERA-103 committee meeting in 1993 in SLC, UT. Many of the faces have changed but there are a few people left from that original meeting. He noted that 2013 is the 10th WNMC organized by the committee. It is the desire to the western directors that this committee will continue to facilitate collaboration in the western region between university personnel and industry participants. The western directors have a competitive directors award ($10,000) that the give to committees to encourage collaboration in the region and suggested that the committee consider applying in 2014. There are some restrictions on the award money can be used. Award money cannot be used to fund speaker honorariums but can be used to fund other components of educational events and for someone to travel to the directors meeting to receive the award. Rich covered the following topic with discussion from the committee:
- Ag research funding faces significant cuts. Some of the capacity funds may become more competitive in the future
- Some discussion about extending the current farm bill beyond 2013.
- The National Research Council will be reviewing Agricultural Food and Research Initiative (AFRI). There is some question about formula funding the future.
David Tarkalson led a discussion on Crops and Soils Magazine. Crops & Soils audience is 15,000 certified professionals. Article length: 1500 words or less. Images are encouraged in .jpg or .tif format, high resolution (at least 300 dpi); size = at least 3.5" wide. Images cannot be in Word and no copies from a web site. Deadlines: The magazine is published every 2 months, Jan-Feb, Mar-Apr. The articles for the next year are due to ASA on Apr 1, Jun 1, Aug 1, Oct 1, Dec 1, and Feb 1. The publication board relies on volunteer articles. A recent article from Montana State Univ. Minimizing urea volatilization in cool semi-arid regions was discussed as an example from the western region. The committee was asked who might like to submit article during the next year. The following volunteered articles of Crops and Soils:
- 1) April 1- Alan Blaylock controlled release fertilizers based on information presented at 2013 WNMC
- 2) June 1- Nat Dellavalle on fertilizer recommendations
- 3) August 1 -Amber Moore work with an author out of a previous issue Nutrient Digest
- 4) October 1- Bob Miller on effect of number of soil cores on soil sample analysis results
- 5) December 1-Eric Bremer on correlation of resin probes to soil testing
- 6) Feb 1- Amber Moore work with an author out of a previous issue Nutrient Digest
David Tarkalson said he will be responsible to follow-up with volunteers to remind them of the deadlines.
Bob Miller led a discussion regarding the poster session. There are 9 student posters (out of 17 total). The student posters will be judged in a competition by Bob Miller, Jim Ippolito, and Tim Hartz. Judges will be using the same form used for ASA student poster competitions. No specific time was scheduled to view the posters so time will be allotted during breaks and after the luncheon. Thanks to Fresno State students for delivering the poster boards for the poster competition.
David Tarkalson led a discussion to identify 2014 off year committee meeting location. Three possible locations were discussed:
- Hawaii (2006 was the last time the WERA-103 committee meeting met there)
- Columbia basin Washington
- Ft. Collins Colorado (would probably need to be later than March)
Rich Koenig led a discussion on NRCS reliance on land grant university guidance for their 590 standard land grant university information. Rich expressed his concern that some of the information that the NRCS has included in their data base of nutrient recommendations is very dated and is no longer valid but is still being used. He indicated that NRCS and EPA have teamed up to put together a list of nutrient recommendations from all states. He expressed concern that if the list is not tied to a document that is current that the incorrect information could be used in nutrient recommendations. If documents are posted in a form like a .pdf document that information is not being updated but should be linked to a website where the information is being updated and is current data. He also has a concern that land grant universities may not have the data to support the 590 standards. He has heard from agronomists in the field that the recommendations are being misinterpreted in the field. There is an opportunity for the WERA-103 committee to work together to identify guidelines that work regionally. Need to identify gaps in the recommendations and determine if other adjacent states have the data to fill in the data gaps. There was discussion regarding the list of nutrient recommendations that Stu Pettygrove has complied for CA. Stu will pass on the information that he has collected on nutrient management in CA to Tim Hartz before he retires. Rich will report to the committee what WA decides to do with the request.
Amber Moore led a discussion on the Nutrient Digest, a quarterly WERA-103 publication regarding nutrient management issues. It covers research and extension subjects on nutrient management in the western region. Amber reported that the Nutrient Digest had received a $2000 grant from IPNI to help support the Nutrient Digest. Amber uses Susan to do the formatting and it usually takes about 10-11 hours per issue to formatting. A motion was made by Bob Miller that when the IPNI grant has been exhausted that the formatting costs be paid by WERA-103 funds. The motion was seconded by Joan Davenport. The motion passed. Amber thanked guest editors for their contribution to the newsletter. It is the responsibility of the guest editor to collect 4 nutrient management related articles and then edit them before submitting to Amber and Susan of formatting. Amber suggested that the guest editors branch out and include articles from other authors outside the WERA-103 committee. There are currently approximately 800 people on the email list. She encouraged those receive the newsletter to forward it on to others. The target audience is anyone interested in nutrient management which include CCA's in the western region. It was also discussed that it might be time for a facelift for the Nutrient Digest. Rob Mikkelsen indicated that IPNI can help with the facelift. Jason Ellsworth indicated that he also has graphic design resources to help with the face lift. It was determined that the WERA-103 committee site on the IPNI homepage also serves as a repository for the Nutrient Digest.
David Tarkalson led a discussion regarding the WERA-103 Website. IPNI is now housing website for WERA-103 committee. When you Google "Western Nutrient Management Conference" it links you to the following https://community.ipni.net/wera . Phyllis Pates has access to upload information to the website. Currently previous state reports, meeting minutes, and WMNC proceedings are on the website. Information regarding the 2013 WNMC meeting was also posted on the website. Joan Davenport and Allison were involved in getting the previous proceedings prepared to go onto the website. It was acknowledged that IPNI is a gold sponsor of the WERA-103 committee and they make their payment in kind through providing services to the committee by supporting the operation of the committee with Phyllis Pates time and talents. Thank you IPNI for all of your support.
Rob Mikkelsen led a discussion on "Agronomic data access: on-Farm/company database use and availability." There is currently in California legislation under consideration that will require California central valley growers to have nutrient management plans for their farms and the crops that they grow. Rob is aware of some companies that have services that track fertilizer applications for growers that may fulfill some of the reporting requirements. Jason Ellsworth indicated that Wilbur-Ellis has some data management ability that is part of their farmer services that will help track nutrient applications under a program called Ag Verdict. Galen Mooso indicated that Simplot has the ability to tract nutrient applications that is called Simplot Smart Farm. Rob indicated that these services will become more important to California growers in the futures at legislative mandates are finalized. This may be a topic for a future WMNC session.
Troy Bauder reported to the committee that funding for the old 406 Water Quality Committee has been slashed. A WERA group for water resources has been formed and will be meeting at Lake Tahoe June 14-15.
From 2:30 to 4 pm the committee was divided in to 3 breakout groups to review past tasks and identify specific tasks / projects that address WERA-103 Project objectives and procedures.
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.

Action Items
1) WERA-103 Secretary will submits an annual report on the committee activities to NIMS within 60 days of the committee meeting which will include a list of participants, state reports, committee meeting and an executive summary. Rich will send Galen the information necessary to make sure that the report can be submitted in a timely manner.
2) At the 2014 committee meeting a sub-committee needs to be appointed that will revise the WERA-103 proposal for submission in 2015 to continue the committee activities for another 5 years.
3) 2014 Directors Award applications are due by March 10, 2014. A sub-committee of Amber Moore and Rob Mikkelsen was decided. This sub-committee will need a reminder on approximately January 1, 2014.
4) Discussion item for the 2014 committee meeting "Where does the committee draw the line of presentation of information on proprietary productions and information?" The question was prompted by a poster submitted by Solivta which has a test that they are selling for biologically active carbon. The poster ended up being not presented because he author is no longer with the company. Guidelines should the recommended for the presentation of information that may not have a scientific component.
5) 2015 WNMC committee needs to make sure there is a time slot scheduled for viewing posters.
6) Item for discussion at the 2014 committee meeting is "What kind of presentations should be expected to provide a manuscript for the proceedings?" Should we expect a manuscript when the presenter is part of the CCA presentations? To view State Reports in their entirety, they can be found at the WERA-103 Homepage under the Additional Documents tab using the following link: http://lgu.umd.edu/lgu_v2/homepages/attachs.cfm?trackID=12156

Collectively, committee representatives reported publication of 62 refereed journal articles; 26 extension publications; 43 proceedings and abstracts; 1 short course; and 2 web sites, all focused on various aspects of nutrient management. A complete list of publications is included in the state report attachment.
WERA-103 objectives
The WERA-103 committee divided into three groups to discuss how we are addressing the three core objectives that have been established for our committee:
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 new model for making nutrient recommendations using boundary analysis was discussed. This methodology can utilize survey data as opposed to replicated controlled experiments. A concern was expressed that there is no funding for the traditional calibration and correlation studies that have traditionally been used to make nutrient recommendations. Some corporate farms are so large that they are creating their own observational data sets. There was discussion about how can we use observational data improve existing fertility recommendations. To make good recommendations you need yield data that is related to environmental information. It may be useful to like yield data with plant tissue analysis. As possible topic for the 2015 WNMC is How can we use observational data to improve nutrient management. Jim Walworth expressed interest in moderating this session. Bob Miller also expressed interest in being involved in this session. Prior to the meeting, Rich Koenig had emailed a master list for the western region on past and present fertilizer recommendations (see previous discussion item). There was discussion about a current emphasis with in NRCS on improving soil health. NRCS agronomist by the name of Ray Archuleta is making visits to western states talking about improving soil health by reducing tillage. He has several presentations on YouTube. There was also discussion about evaluating the efficiency of new fertilizer products and technologies. There is confusion about how products get approved for incentive NRCS/USDA programs. NRCS seems to rely heavily on land grant university data when land grant universities are not necessarily testing all products. There is no minimum performance level. There is no consistency form state to state. Who's job is it to evaluate the efficiency of fertilizer products for efficiency? Does there need to be a clearing house for non-traditional soil amendments? There was also some discussion about a new Solvita test for soil health which measures soil respiration and there was concern that on western soils that it may not correlate to N mineralization.
Objective 2: Promote effective use of soil plant testing information
This group discussed the question "How do you integrate analytical data into fertilizer recommendations?" They discussed Biological Nutrient Program developed by OSU to predict N mineralization by organic N sources. Crop Manager is a program developed by the California system to schedule irrigation applications and N applications. Crop Time is another tool developed by OSU to predict growing degree days. Western Labs out of Canada has commercialized resin probes to predict nutrient availability. Tim Hartz will be the keeper of Stu Pettygroves data base that he has developed over the years. Bob Miller indicated that the revision of the 2005 Methods Manual is complete and under review. Meleich 1 and 3 methods were removed from the new edition.
Objective 3: Provide education on the principles of soil-plant-animal-water system management and the tools and practices that lead to sustainable agricultural production.

Impacts
- The purpose of a WERA (Western Education/Extension and Research Activities) is to bring researchers together to coordinate related research without the need for a formal multi-state research plan, to organize technical conferences, work groups, task forces, or symposia for exchange of experience and opinions.
- The primary impact of the WERA-103 Committee has been to disseminate knowledge through the Western Nutrient Management Conference (biennial basis) for over 20 years. This conference brings agricultural professionals and industry members from the western region together to provide training and communication regarding nutrient management.
- The work of the WERA-103 committee has: 1) improved fertilizer use efficiency in the Western Region; 2) improved use of animal waste in environmentally safe ways; and 3)provided information to consultants and governmental agencies that can lead to less nutrient contamination of ground and surface water resources.
