Project Description


Little Ontario research has been done on soybean potassium (K) needs. The relative chloride (Cl) sensitivity of Ontario cultivars has not been tested. The objectives of this project were to determine whether Cl or magnesium applied with K fertilizers influence soybean response to K, and to determine whether Ontario soybean varieties differ in response to K and sources of K.
