Many nutrients and lime are not mobile in the soil. When applied to the soil surface without tillage, these materials remain in the top 2 inches, especially in production systems that lack tillage. If a soil sample is taken...
Ron Jirava’s approach to conservation tillage helps his farm to remain economically viable. Learn more in this farmer-to-farmer case study.
Lorin Grigg grows onions and sweet corn under sprinkler irrigation in Quincy, Washington. In this publication, Grigg discusses his strategy for cover cropping to protect seedlings from windblown sand and reduce wind erosion.
Scientists have developed a new approach to modeling potentially drought-prone soils in Pacific Northwest forests, which could aid natural resource managers to prepare forested landscapes for a changing climate.
Some farmers in the Inland Pacific Northwest have reported lower grain yield of spring cereals with no-till (NT) compared to conservation tillage (CT). A 4-year field study was conducted in a 12-inch annual precipitation zone to determine tillage method and sowing rate effects on seed-zone water, seed-zone temperature, plant stand, grain yield, grain yield components, and straw production for three spring-sown cereal species.
Christmas trees planted in unirrigated sites depend on the weather for survival. A research trial set out to find factors that would help seedlings survive during drought years. Results were mixed.
Most “sick tree” problems can be traced back to underlying stresses that have reduced the tree's vigor, making it more vulnerable to diseases or insect pests.
The wet and mild conditions of autumn can help prevent transplant shock.
At times we see many of our cool-season perennial and annual forages looking stressed and growing very slow as they struggle with heat and no rain. The hot, dry conditions we sometimes experience in western Oregon have many ...
