6.2.11 Pond Class

A decision support system that provides guidelines for freshwater pond fertilization and liming. Nutrient requirements for a pond are calculated using limnological principles. A linear Programming algorithm enables calculation least-cost inorganic and/or organic fertilizer combinations that meet the predicted nutrient requirements. Lime requirements are calculated on the basis of soil pH-percent base saturation relationships developed for major categories of soil types. Version 1.2 provides limited capabilities for simulating pond water temperature.
