Abstract
We summarize a series of developments in modeling soil water dynamics and plant responses and their applications in water management decision-making and irrigation scheduling.
A numerical model was developed to simulate root water uptake (transpiration), nitrogen uptake, and plant response to water and nitrogen environment in the root zone.
Improvements to the model, published in a series of manuscripts, include use and matching of root distribution to water in soil in uptake processes, consideration of plant stress and recovery in uptake, consideration of salinity, an index of plant water deficit and its coupling with soil water status for uptake prediction, and the use of the index and model to optimize irrigation scheduling.
