8. QUANTATIVE INVESTIGATION OF CIRCULATION PATHS OF ESSENTIAL ELEMENTS: Nitrogen (N) Potassium (P) Calcium (Ca) Input From Rain. Subsoil Weathering. Circulation within Forest-Soil-Animal System. Losses by way of Crops of Plants or Animals. Runoff in Dissolved & Particulate Forms. Evolved a Circulation System which reduces Nutrient loss from leaching and runoff by keeping Most of the minerals locked up in Vegetation.
