The Mathematical Model as an Aid to Developing Concepts concerning the Soil-Atmosphere-Crop Relation

The relation between light absorption rate and crop growth rate may be deduced from the kinetics of net photosynthesis showing that for a crop, such as winter wheat, growing from winter to summer this relation must be S-shaped. Altering the soil-solution nutrient level changes, in an opposite sense,...

Description
Summary:The relation between light absorption rate and crop growth rate may be deduced from the kinetics of net photosynthesis showing that for a crop, such as winter wheat, growing from winter to summer this relation must be S-shaped. Altering the soil-solution nutrient level changes, in an opposite sense, the root:shoot ratio, thereby changing light interception. Destruction of live roots by soil organisms by increasing root growth enhances the long-life organic content of the soil. The relation between growth of the plant and the growth of seeds or tubers on the plant is determined by their relative competitive strengths for attracting nutrients.
