Current Work Focus:

Lead the research program on environmental issues including erosion control, excessive nutrient losses in surface water runoff, and groundwater contamination with nitrate and Dacthal breakdown products. Effectively participated in a cooperative team effort to correct environmental problems in the County.

Wrote much of the station web site.

Conducted research with emphasis in three areas: water quality issues (including soil water measurements), product quality, and new crops. Water quality research made progress that was immediately implemented. Erosion control practices with mechanical furrow mulching and polyacrylamide were developed and proven effective. Fertilization and irrigation methods were developed that saved growers N costs, and protected groundwater. Natural soil N-mineralization was discovered to contribute more available-N to the soil-plant environment than previously thought. Growers' N fertilizer costs were lowered. Environmental N loading was reduced.

Soil water measurements using GMS were developed. Calibrations of instrument readings are being used by growers world wide. Product quality of sugar beets is increasing by the use of soil N-mineralization credits for calculating N requirements. Better beets (less conductivity) results from lower N fertilizer inputs. Consequently many growers now use the beet crop in the crop rotation to ''sop up'' available-N, helping to protect the ground water from nitrate contamination.

New crops being investigated include native range plant seed productions, soybeans, poplar trees, and Hicksii yews.

Continued grower support trials that include variety and crop quality testing on onions, potatoes, sugarbeets, small grains, and alfalfa.

Onions grown under automated drip irrigation had improved yield and quality.

Real time late blight risk was predicted using the ''Wallin model''.

Evaluated drip irrigation for use overseas. Evaluated erosion around the Ilha Grande Bay in Brazil as a short term consultant. Developed specific recommendations for decreasing the potential for erosion.
