An Integrated Decision Support Package for Evaluation of Reactive Phosphate Rock Fertilizer Strategies for Grazed Pasture

摘要

A reactive phosphate rock (RPR) submodel has been incorporated into an integrated decision support package, Overseer~(TM) which is a tool to derive site-specific phosphorus (P), potassium (K), and sulfur (S) nutrient recommendations accounting for thekey biophysical, economic, and environmental factors that influence fertilizer requirements and effects. The software uses input information readily available to farmers and their consultants and is primarily targeted to fertilizer company representatives and farm consultants.
