Abstract:: This publication provides information on the timing and pattern of biomass accumulation and nitrogen (N) uptake for a variety of Pacific Northwest crops. You can use this information to schedule N fertilizer applications for maximum efficiency. To achieve near-maximum crop yields, an adequate supply of available N must be present...

Abstract:: Biosolids are a by-product of municipal wastewater treatment. They contain organic matter and nutrients that are beneficial for soil, crop, and livestock productivity. Raw sewage solids must be processed to meet U.S. Environmental Protection Agency (USEPA) standards before they can be called biosolids. This publication focuses on how biosolids can...

Abstract:: Accumulation of excessive salt in irrigated soils can reduce crop yields, reduce the effectiveness of irrigation, ruin soil structure, and affect other soil properties. This publication is designed to help you evaluate the kind and amount of salts present in soils and to select management alternatives. This publication describes the...

Abstract:: This nutrient management guide is designed to assist onion growers and crop advisors in producing a high-quality crop while protecting the environment from excess nutrients. Nutrient management strategies recommended here are based on data accumulated over many growing seasons with many different onion varieties in Idaho, Washington, and Oregon. This...

(Dan Matthew), 1954-, Horneck, Donald Arthur, Brown, Bradford D., Stevens, Robert G., and Pacific Northwest Cooperative Extension
Abstract:: This publication focuses on how to design a soil nutrient monitoring strategy that fits today’s requirements for record keeping and increased accuracy in managing nitrogen (N), phosphorus (P), and other nutrients. We advocate the use of management units or zones for soil testing and nutrient application. To measure a real...
