GLRPPR Sector Resource: Annual Phosphorus Loss Estimator (APLE)
Annual Phosphorus Loss Estimator (APLE)
APLE is a Microsoft Excel spreadsheet model that runs on an annual time step and simulates sediment bound and dissolved P loss in surface runoff. It is intended to simulate edge-of-field P loss for uniform fields of several hectares in size, or smaller. APLE considers different kinds of animal manure (beef, dairy, poultry, swine), applied either by machine or by grazing beef or dairy cattle, and highly soluble commercial fertilizers.
