Research Interests
My research program focuses on soil-plant-water relations, soil physical and hydrologic health, soil fertility, and water-nutrient interactions. Key questions include: How can we manage soils to improve water relations, and how can we manage water to optimize soil processes and plant productivity? In western Washington where my research program is based, infiltration and hydraulic conductivity are central considerations for farmers wanting to get excess water off the field during the wet winters, but dry summers and limitations on irrigation mean that the soil’s water-holding capacity quickly becomes a key factor. With regard to soil fertility, key interests include nutrient requirements of understudied crops, the relationship between soil properties and crop nutrient requirements, interactions between nutrient management and plant health, and impacts of novel or alternative irrigation practices on soil nutrient dynamics. The focus of my Extension program is to help farmers to make informed decisions about managing soil moisture, irrigation, soil health, and soil fertility to improve productivity, reduce costs, safeguard plant health, and promote good stewardship of our natural resources.
