Evaluate Soil Test Results for Applications of Nutrients

The application of some micronutrients has been shown to increase winter and spring wheat production yields. A full analysis of soil samples will provide information as to which essential nutrients are deficient and providing limited availability to the young plants as they develop. Recent research results have shown the potential to increase winter wheat yields by 6 bushels (7% increase) per acre and spring wheat as much as 12 bushels (15% increase) per acre, data collected by Paul Carter in Columbia and Walla Walla Counties.Application of nutrients can be applied after seeding in many cases and will be available to the new young plant roots as they begin to develop.Soil acidity and health is of primary concern as growers continue to pursue yield increases and manage for even greater production while managing herbicide applications, water infiltration and use efficiency, and residue breakdown.The 2017 WSU Wheat Academy will include a session on essential soil nutrients, deficiency symptoms, and soil test results.
