Treating Salinity and Sodic soil with Recycled Gypsum
Treating Salinity and Sodic soil with Recycled Gypsum A sodic soil has an exchangeable sodium percentage (ESP) of more than 6. This means that sodium comprises more than 6% of the total exchangeable cations in the soil. Sodic soils are likely to disperse, that is, break down into individual clay particles that block pore spaces. This dispersion
