Interpretive Summary:

Technical Abstract: The Annual P Loss Estimator (APLE) is a simple spreadsheet model developed for predicting annual field-scale dissolved and particulate P loss in surface runoff as well as annual changes in soil test P (STP). The model accounts for field application of P through the addition of animal manure (solid and liquid), dung from grazing cattle, and inorganic fertilizer. This empirical annual time step model was designed to provide a relatively easy-to-use tool for those without significant modeling experience. The APLE model is currently available only as an Excel spreadsheet and thus its user interface is limited and not easy to navigate. We have developed a graphical user interface (GUI) for APLE that reads in data populated in Excel spreadsheets without requiring users to scroll through different worksheets to enter data and view results. This GUI provides a more seamless way to run the model and view model output.
