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 […]
