  30. Developed a joint proposal with the Polish Academy of Sciences, Institute of Agrophysics in Lublin to develop instruments for measuring soil water status. This resulted in Dr. Marek Malicki spending two years with us and was instrumental in the evaluation of moisture blocks and other methods. As a result upon his return to Poland, he has developed very simple instruments for measuring soil water content using the TDR method (time domain reflectrometry). This instrument promises to be much more inexpensive ($600) than present instruments ($6000).

  32. Spent a month in South Africa in 1988 to advise the Ministry of Agriculture on research in irrigation as related to crop water use and productivity. Emphasis was on initiating people to the use of models to organize their research plans and evaluate research.
  33. Developed a proposal, with Gail Bingham, to provide instruction and training on "water production functions as related to time and amount of irrigation and rain". As a result there are two visiting scientists (Drs. Srivastava and Rao) training at USU (Aug. 1989 - Jan. 1990). A two-week short course will be developed to be given in India in 1990 or 1991.
  34. Developed training programs 1987 and 1989 for several students from Pakistan (Mirza and Raza) to upgrade their education to the use of models and simple computer techniques to organize research planning and evaluation.
  35. Invited to give two papers at the 1990 Western Soil Science Society meeting in Davis, CA, in the symposium "Agricultural Water Conservation and Quality" - 1) Comparison of Water Application Systems for Conservation, and 2) Long-time Use of Power Plant Water with Limited Irrigation.
