Method and System of Determining Soil-Water Properties

A system and method for simulating soil moisture of farmland and large agricultural areas in three dimensions is described. The invention utilizes numerical techniques to solve a three dimensional boundary value problem which is defined by the soil to air interface (surface, x and y), and soil below surface (depth along the z axis) over the area of interest. Solved are key parameters which describe the soil which include soil particle size distribution (soil type), Hydraulic conductivity (water flow in the Z axis) Soil water diffusivity (water moving in the x, and y direction). This model will result in delivering soil moisture readings and soil water storage as a function of time thereby helping local managers of farmland or large agricultural areas to optimize watering and care of crops.
