Can someone please recommend a software analysis tool that use water quality parameters (EC, SAR, pH, salt concentrations, etc) to evaluate quality of irrigation water and potential effect on soil health?
Dear Gerhard,
Several models exist for water and solute transport in the soil, such as SWAP, DRAINMOD-S, UnSatChem, and Hydrus. They are based on Richard differential equation in combination with the differential equation of convection-diffusion Fick for advection and dispersion of the salts. There are also simple models as SALTMOD. It is useful for the long-term salinity forecasts relative to irrigation and drainage practices.
With my best regards
Prof. Bachir ACHOUR
Thank you for this info Prof. Is there maybe a model that is more applicable to soil health in terms of salt toxicity to soil biota?
