projectblue.blob.core.windows.netSoil organic matter (OM) is the term used for all living or once-living materials in the soil. It adds to soil fertility and enhances the physical, chemical and biological properties of soil. It is critical to soil health, although the precise contribution of OM to soil function remains poorly understood. However, there is growing evidence

SSP is defined as the ration of sodium in epm (equivalents per million) to the total cation epm multiplied by 100.A water with a SSP greater than 60 per cent may result in sodium accumulations that will cause a breakdown in the soil’s physical properties.
