University of Virgin Islands Mick O'Neill, New Mexico State University Larry Parsons, University of Florida Dana Porter, Texas A&M University Danny Rogers, Kansas State University Larry Schwankl, University of California, Davis Ken Shackel, University of California, Davis Clinton Shock, Oregon State University Prem Singh, University of Guam Tom Spofford, NRCS Hank Taber, Iowa State University Todd Trooien, South Dakota State University
The 2001 Business Meeting was convened.
The Minutes of the 2000 Meeting were discussed and it was moved (Shackel moved, Taber seconded) that the minutes be accepted. The vote was unanimous in favor of acceptance.
Discussion on nomination of an incoming Secretary was opened. Clint Shock volunteered to serve as Secretary in 2002. It was moved (Clark moved, Shackel seconded) that Clint be the 2002 W-128 Secretary. The motion was unanimously accepted.
Discussion was opened on the location of the 2002 meeting. It was suggested that the W-128 meeting be held in conjunction with the 2002 IA meeting in New Orleans (Oct 24-26, 2002). Jackie Robbins, an irrigation equipment dealer in the New Orleans area, had volunteered to arrange a tour for W-128 members. After some discussion, a decision was tabled until further discussion which was to be held the next morning (Wed, 11/7/01).
Freddie Lamm discussed the results of the W-128 technical session at the 2001 IA conference. Approximately 45-50 attended the session. It was felt that the IA technical session was effective in getting W-128 activities recognized and it was an effective means of extending the results of W-128 sponsored research.
Freddie Lamm also discussed the current status of the rewrite of the microirrigation book Trickle Irrigation for Crop Production. Numerous W-128 members are contributing authors. Drafts of all the chapters have been submitted and revisions are proceeding.
Maintenance and hosting of the W-128 web site was discussed. New Mexico was not interested in continuing to host the web site. Clint Shock, Oregon, will take over hosting and maintaining the web site. He will work with Mike Burke to make sure that the W-128 membership list is up to date and posted to the web site.
Tuesday mornings business meeting concluded and State reports commenced
The meeting adjourned at 5:10 pm.
Wednesdays (11/7/01) meeting began at 8:25 AM.
A break was taken at 10:30 AM.
At 10:50 AM, the business meeting was re-convened to discuss the location of the 2002 meeting. It was decided that the W-128 meeting would be held beginning Oct 22, 2002 and ending at noon on Oct 24, 2002 in New Orleans. The IA meeting begins on the afternoon of Oct 24 and continuing through Oct 26, 2002.
Freddie Lamm will investigate again having a W-128 technical session at the IA conference.
Mike Burke gave an update on the status of the W-128 project. Discussed was the current membership of the project. He also discussed that a publication list, a list of students (undergrad and grad) who have been involved with W-128 related activities, and oral presentations by W-128 members extending the results of W-128 activities will need to be submitted.
It was also decided that Mike Burke would work with Clint Shock to get an updated W-128 membership list on the web site.
The Wed AM business meeting adjourned at 11:30 AM.
State reports resumed at 1:00 PM.
The W-128 Wednesday meeting adjourned at 6:00 PM.
Thursday (11/8/01) meeting of W-128 was a Technical Tour. The tour began at 7:40 AM and included five stops.
The first stop was a Turfgrass Demonstration Site. We were met by Joe Taylor of the Bexar County Texas Cooperative Extension who explained the demonstration and its out-reach activities.
The second stop was site in which water interception by Juniper trees was being investigated. The W-128 tour was met by Keith Owens of the Uvalde Research and Extension Center who discussed the on-going research work.
The third stop of the tour was the Honey Creek State Natural Area. We were met by NRCS and Texas CE personnel who discussed activities in the area. Among other topics, a USGS monitoring weather site was visited.
The fourth stop was an application site of effluent through subsurface drip dispersal systems. Paul Reynolds of Wastewater Technologies met the tour at a school site where such a system was in place.
The final stop was a site where subsurface drip systems were being used for pepper production. Jerry Parsons of Bexar Co. Texas CE met the tour and explained the on-going trial.
The days tour ended at approximately 4:00 PM.
