Effects of Straw, Calcium Chloride, and Submergence on a Sodic Soil1

B. S. Puttaswamygowda and P. F. Pratt2

ABSTRACT

The effects of straw and CaCl2 during 130 days of submergence, and the effects of these amendments under submerged aerobic vs. anaerobic conditions for a period of 30 days were studied. Comparisons of pH, EC, Na, Ca + Mg, K, Fe, the optical density of the water extract, and ESP were used to evaluate the effects of these amendments. The straw and straw + CaCl2 treatments had the largest effect in lowering the pH and the ESP, increasing the Na and Ca + Mg concentrations and the EC. Submerged anaerobic conditions had the largest effect on promoting these reactions. The concentration of Fe2+ was highest in the straw treatments whereas CaCl2 had a depressing effect on the soluble Fe2+. The optical density was lowest in the straw plus CaCl2 amendment treated soil and the effect of this treatment was larger under anaerobic conditions.

Wheat straw under anaerobic conditions caused an increase in the sum of Na plus Ca plus Mg that was about three times greater than the sum of these cations in the straw itself. In combination with CaCl2 wheat straw reduced the loss of Ca from solution observed when CaCl2 alone was added to soil.
