Preliminary experiments were conducted to evaluate the addition of H/sub 2/SO/sub 4/ to high Na water for the purpose of preventing or reducing plant uptake of Na by increasing the solubility of Ca. The addition of up to 4 meq/liter of H/sub 2/SO/sub 4/ to irrigation water containing 1 to 40 meq/liter of NaCl had no significant effect on the growth of peas (Pisum sativa) and beans (Phaseolus vulgaris) cropped twice in calcareous soils in greenhouse experiments. However, H/sub 2/SO/sub 4/ had an adverse effect at NaCl na concentrations of 60 and 80 meq/liter. Sodium concentrations greater than 10 meq/liter appeared to decrease the yield of both plants. A leaching fraction of 0.3 + or -0.05 was maintained. The Na content of the plant material increased as the Na content of the irrigation water increased, but no reduction in na content was observed with the H/sub 2/SO/sub 4/ treatment. The Ca content was not affected. The results suggest that this practice was ineffective at the H/sub 2/SO/sub 4/ concentration range studied.
