Brief Summary of Minutes of Annual Meeting

March 6, 2019, El Dorado Hotel, Reno, NV (see full minutes in Appendix 2)

Executive Committee Election

As of the end of the meeting, executive committee includes:

Eric Bremer, Chair

Jay Norton, Vice-chair

David Tarkalson, Secretary

Update and Discussion of IPNI Closure

IPNI will close at the end of May, 2019. Since IPNI has been handling the WERA-103 bank account, providing logistical support for the Western Nutrient Management Conference (WNMC), which is held every other year (odd-numbered years) by WERA-103, and publishing and housing on-line archives of WNMC proceedings, WERA-103 must identify alternatives for each of these activities as soon as possible. Many possible solutions were discussed and a subcommittee including the executive committee plus Cindy Smith, Jim Ippolito, Joan Davenport, Alan Blaylock, Grant Cardon, and Fabian Hernandez (as SSSA liaison) was formed with the charge of identifying a way to continue the WMNC by the end of 2019. The subcommittee will meet by teleconference on April 26.

Financial Report

Account balance is $20,814 as of 06-Mar-2019. This amount tends to be about how much WERA-103 spends prior to each conference and then brings in from registration. Total attendance held constant at 130 ±2 during the 2013, 2015, and 2017 WNMCs after increasing from 62 in 2009 to 90 in 2011. An urgent aspect of transitioning away from IPNI support is to find an alternative place for WERA-103 funds by the end of May. See full report in Appendix 3.

Contributions to Crops and Soils Magazine

Volunteers to provide ~800-word articles for the bimonthly publication:

1. May 1: Nat, Gypsum requirements;
2. June 1: Grant, N requirements following alfalfa;
3. August 1: Christopher, CaCO₃ testing;
4. October 1: Joan, blueberries;
5. December 1: Jim W., soil variability in pecan orchards;
6. 1, 2020: Haiying Tao (Alternate: Jim I.)

2020 WERA-103 Meeting

Will be held in Hawaii. Executive committee will coordinate details with Jonathan Deenik.

Administrative Advisor Report

Rich Koenig reviewed procedures for submitting this annual report and for preparing and submitting the WERA-103 Renewal Proposal by the due date of January 15, 2020. Rich noted that this multi-state project must be renewed every five years based upon a proposal that makes a case for renewal. The Renewal Proposal will be prepared by the executive committee along with Urszula Norton and Amber Moore.

Rich reviewed the structure and procedures of multi-state projects like WERA-103, including submittal of the Appendix E to join and that universities are required to spend a percentage of USDA formula funds on this type of multi-state activity. He noted that there is no difference between WERA projects and multi-state research projects and that states that recognize them differently are mistaken. Extension programs and Ag Experiment Stations both need to invest formula funds in these multi-state extension and research activities.
