9. How many grams of limestone with a CaCO3 equivalent of 100%would you need to apply to an acidic soil with 85% exchangeable Alsaturation to reduce it to 10%? The CEC of the soil is12.5cmolc/kg.
10. How many grams of gypsum (CaSO4.2H2O) would you need toreclaim a sodic soil with an exchangeable sodium percentage (ESP)of 80% to reduce to it to 50%? The CEC of the soil is12.5cmolc/kg.
