1. Factors Affecting the Relative Benefit of Deep-banding versus Broadcast Application of Phosphorus and Potassium for Corn and Soybean

Scientifically based recommendations concerning the choice of deep banding versus traditional broadcast application of phosphorus (P) and potassium (K) for corn and soybean production in conservation tillage systems have been hampered by insufficient research and inconsistent results. Even when the decisi on is made (e.g. by strip-tillage corn farmers) to go with deep- banding of P and K, numerous questions remain about fertilizer rates, optimum deep-banding depth and frequency, whether to have a...
