Abstract
A soil solution displacement method was used to evaluate the effect of CaCO3 on soil retention of sulfate. A decreased amount of sulfate retention was noted with increased rates of CaCO3.By means of a split‐root technique, plants of soybeans (Clycine max (L.) Merrill) and cotton (Gossypium hirsutum L.) were grown in a Dothan subsoil which contained a large amount of adsorbed sulfate, and to which had been added several rates of CaCO3. As CaCO3 rate was increased the uptake of sulfate by five crops of soybeans and one crop of cotton grown successively in the same soil was generally greater. A portion of the adsorbed sulfate in the untreated soil was available, but available sulfate became limiting for the third crop of soybeans and for all successive crops of soybeans and cotton.This publication has 0 references indexed in Scilit:
