Abstract:
Cinnamon soil with relatively high calcium was used as material，using batch method of constant temperature oscillation,the effect of two kinds of exogenous low molecular weight organic acids (oxalic acid and citric acid) on soil calcium，phosphorus release kinetics characteristics was studied.The results showed that adding oxalic acid and citric acid could promote the release of calcium element in the soil.With the increase of organic acid concentration，calcium releasing quantity in the soil increased gradually.The activation capacity of exogenous low molecular weight organic acids to calcium element in the soil was oxalic acid
