Recently, researchers at Iowa State University discovered a way to increase the accuracy of a popular crop model. By zeroing in on early stages leading up to kernel formation, scientists believe they ...

Mathematical models may be used to develop management strategies that optimize the use of nutrients from complex sources such as manure in agriculture. The Precision Nitrogen Management (PNM) model is ...

This image shows mechanistic (top row) and empirical (bottom row) simulations compared recent, or "baseline," maize production in South Africa (1979-99) to projected future production under climate ...

The study presents a theoretical basis of a stomatal behavior-based coupled model for estimating photosynthesis, A, and transpiration, E. Outputs of the model were tested against data observed in a ...
