A nutrient uptake model that accurately predicts the P uptake of crops in the field where environmental conditions are continually changing can be a useful tool in developing more efficient systems of fertilizer applications and recommendations. The objectives of this research are: 1. The determination of the effects of P rate, P dilution, and P band number on root distribution and root growth function of corn. 2. The evaluation of the Barber - Cushman mechanistic P uptake model under South Dakota field conditions.
