Relation of Fertilizer Placement to Nutrient Uptake and Crop Yield: II. Effects of Row Potassium, Potassium Soil-Level, and Precipitation1
- Stanley A. Barber2
Both potassium soil-level and row potassium treatments were about equally effective in supplying potassium for a corn-soybean-wheat-hay rotation. Relative increases in corn and soybean yields due to potassium fertilization were inversely correlated with the amount of rainfall which occurred during the growing season.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
