A New Roadway to Improving Phosphorous Management in Crop Production
Supplying adequate phosphorus (P) to crops in an essential component of agronomic systems. The availability of P in agricultural soils is influenced by interactions between soil properties and management strategies. Shifts in management strategies can have effects upon soil P availability, soil-test P, yield response, and susceptibility of loss to surface runoff and erosion. Improvements in P management require looking at the whole system, and considering agronomic, economic, and environmental outcomes of management decisions.
