Abstract:

Four neighboring locations, two noncultivated and two gypsum-treated, were sampled and analyzed for chemical composition of soil solution. Accumulation of soluble sodium salts in the gypsum-treated loessial soil irrigated with sodic waters was found to be significant after 11 yr of amendment application. A combination of high salinity and low ESP values in the topsoil significantly improved soil hydraulic conductivity and thus enhanced salt input and accumulation. It is predicted that continuation of such management could result in an increase in the concentration of sodium-soluble salts at shallower depths. Under these circumstances, the common ion effect would inhibit gypsum dissolution, thus making additional gypsum application useless.

Long term effects of extensive gypsum amendment applied with sodic water irrigation on soil properties and soil solution chemical composition

Four neighboring locations, two noncultivated and two gypsum-treated, were sampled and analyzed for chemical composition of soil solution. Accumulation of soluble sodium salts in the gypsum-treated loessial soil irrigated with sodic waters was found to be significant after 11 yr of amendment application. A combination of high salinity and low ESP values in the topsoil significantly improved soil hydraulic conductivity and thus enhanced salt input and accumulation. It is predicted that continuation of such management could result in an increase in the concentration of sodium-soluble salts at shallower depths. Under these circumstances, the common ion effect would inhibit gypsum dissolution, thus making additional gypsum application useless.
