Irrigated Warm Season Cover Crops for Western Oregon
Cover crop use is increasing in the Pacific Northwest, but information is not readily available on the growth potential, biomass production, adaptability, and bloom period of warm season cover crop species and/or varieties for this region. A study was conducted in 2015−2016 at the United States Department of Agriculture – Natural Resources Conservation Service (USDA-NRCS) Plant Materials Center in Corvallis, Oregon to evaluate commercially available summer cover crops for the Willamette Valley of western Oregon. The replicated trial included ten warm- season species that were evaluated for emergence, canopy cover, vigor, pest and disease susceptibility, bloom period, plant … Read the rest
Oregon State University Cover Crop Calculator and User Guide
This free online tool compares the nutrient value and cost of cover crops, organic and synthetic fertilizers and compost. Use this Calculator to develop well balanced and cost effective nutrient management programs for your farm. Developed by Nick Andrews, Dan Sullivan, Jim Julian and Kristin Pool.
The OSU Organic Fertilizer and Cover Crop Calculator is a tool to assist with preplant nitrogen (N) input decisions. It forecasts the quantity of plant-available nitrogen (PAN) provided by inputs such as fresh organic materials, cover crop residues, and finished compost.
