Potassium (K) is an important nutrient for soybean development. After Nitrogen, K is the most heavily absorbed nutrient in soybeans. A large portion of potassium is stored in the soybean seed and is therefore removed from the field each year at harvest. Potassium deficiency can severely limit soybean yield potential; deficiencies can also lower disease resistance and impact nodule formation.

This project was set up to assess if added liquid potash fertilizer can increase soybean yields and reduce deficiencies by providing an easily accessible source of potassium. The project also evaluated what soil types would have the greatest responses based on the existing soil test levels.
