www.nrcs.usda.govgiven amount. As cation exchange capacity increases (higher clay and organic matter), the amount of liming material needed to change soil pH also increases. Soils with a low cation exchange capacity may only require 1 ton of agricultural limestone to change a pH from 4.5 to 6.5; whereas, a soil with a higher CEC may require 2 tons

www.dmr.nd.govDispersion will occur when more than 15% of the cation exchange capacity sites on clays are occupied by sodium ions and when the total EC in the soil solution is low. The potential dispersion of a soil can be determined by the exchangeable sodium percentage (ESP). Soil dispersion results in: • Loss of soil structure • Loss of pore structure
Zeolite Ion Exchange Softening - MRWA
www.mrwa.comThese reactions represent cation exchange, the exchange of positive ions. To replenish the sodium ions used, units need to be regenerated with material containing high amounts of sodium, normally salt brine. This allows the resin to be reused many times. Ion-exchange does not alter the water’s pH or alkalinity. However, the stability of the ...
