Abstract
A mathematical model was developed which describes water uptake by a plant as a function of leaf water potential, initial soil water potntial and other soil and plant parameters. The model utilizes two nonlinear partial differential equations for which there are no known analytical solutions. Therefore, to operate the model it was necessary to develop a numerical procedure employing finite difference techniques for the solution of the equations. A computer program, MULTROOT, was developed to solve the numerical model on a digital computer. A review of the literature presented describes the studies made on soil water potential.
