Impact of Biochar, Black Liquor, and Fly Ash Application to Soil on Productivity of Wheat in Eastern Washington

Soil acidification is a significant issue faced by agriculture in Eastern Washington. Acidification increases concentration of exchangeable aluminum (Al) in soil and reduces nutrient availability leading to reduced plant vigor, greater disease incidence, and reduced yield. Liming is the recommended remedy, but economic feasibility is questionable due to its high cost and limited supply of […]

Sustainable Crop-Livestock Integration for System Health in the Dryland Inland Pacific Northwest

Dryland wheat-fallow producers have begun switching to a direct seed tillage system for soil health benefits such as reduced runoff, increased water infiltration, increased consistency of crop stands, more and longer period of surface cover from crop residue, better soil moisture, and fewer dust clouds at planting time. However, this practice often requires increased pesticide […]
