Animal dietary P management can significantly alter both the amount and forms of P excreted in manure. We will show how phytase, high available P (HAP) grains, and reductions in non-phytate P impact manure P excretion and P transformations during storage. We also will show how the manure generated impacts P loss from soils under simulated rainfall.
