Abstract

Pot experiment conducted to find out the changes in soil properties due to the use of bicarbonate waters for rice in the presence and absence of pyrite application revealed that increase in the RSC of water, increased Soil pH, EC., CO, HCO3, Na, exchangeable Na*, Exchangeable Sodium Percentage (ESP) and CaCO3. Decrease in SO4, Ca, Ex.Ca2, Ex.Mg2 and Ex.K* was observed with the increase in levels of RSC of the water used. Pyrite application altered all the above said soil properties to an appreciable magnitude, commensurate with the quantity. However, the trend was exactly in contrast with the absence of pyrite application.
