One important cool-season perennial grass seed crop grown in Oregon is fine fescue (Festuca rubra L.). Open-field burning has been used for many decades to manage pests, cycle nutrients, and stabilize yield, in fine fescue seed fields, especially as stands age. Legislative restrictions currently limit open-field burning to 6,070 hectares...
This guide covers key nutrient management topics related to tall fescue grown for seed in western Oregon. Crop growth and timing of nutrient uptake is covered. Specific recommendations for nitrogen, phosphorous, potassium, sulfur, and soil pH provided. A number of appendices address micronutrients, and other research projects that are relevant...
This guide provides nutrient and lime recommendations for establishment of turf and forage perennial ryegrass grown for seed in western Oregon. Healthy plants with adequate root systems are required to obtain the greatest return from your fertilizer investment. The nutrient recommendations in this guide assume that adequate control of weeds,...
Soil acidity, expressed by low soil pH, causes reduced crop growth and significant economic loss. It is the most commonly overlooked and poorly understood yield-limiting factor in western Oregon and a developing concern in eastern Oregon. This publication describes the concept of soil acidity and the limitations it causes for...
This publication describes how to estimate lime application rate and lists criteria for choosing liming materials (source), lime application method (placement), and how often to apply lime (frequency).
This publication incorporates 20 years of field research by OSU faculty comparing two grass-seed residue management methods: full straw load (straw is chopped and left on the field) and clean nonthermal (straw is baled and removed from the field). Comparison includes discussion of seed yield and quality, nutrient management considerations...
