Improving the availability of phosphate fertilizer in the soil can significantly improve the yield and quality of crops, which is related to China’s food security. In the present study, malonic acid, a low molecular weight organic acid, was used as a synergist and monoammonium phosphate. The results showed that the availability of phosphorus increased by 12.02% compared with monophosphate. By analyzing the morphology and correlation of inorganic phosphorus in the soil, it was found that the conversion rate of Ca2-P to CA8-P slowed down. Therefore, the addition of malonic acid can improve the availability of phosphate fertilizer in calcareous soil.
