Abstract: To improve soil quality and alleviate phosphorus leaching caused by soil acidity after long-term fertilization, a field experiment was designed and consisted of seven treatments: No phosphorus fertilizer application (CT); applied FCMP at 45 kg/hm2 (45FCMP); applied FCMP at 90 kg/hm2 (90FCMP); applied FCMP at 180 kg/hm2 (180FCMP); applied calcium superphosphate at 90 kg/hm2 (SSP); applied diammonium phosphate at 90 kg/hm2 (DAP) and applied FCMP at 45 kg/hm2 combined with diammonium phosphate at 45 kg/ hm2 (FDAP). The results showed that phosphorus fertilizer application helped to increase the corn production, and the increases of corn yield was 20.8% with 90FCMP, 4.8% with SSP, 5.7% with DAP and 18.1% with FDAP compared to CT. Moreover, an equation for the relationship between corn grain and the amount of FCMP application was:y =22.073x -0.1027x 2 5537.4, and 107.5 kg/hm2 of FCMP was required to get the highest corn yield. Thus, this research suggests that FCMP application is a new technique to further increase the corn grain yield in Shajiang Black Soil. Moreover, because of its alkaline, FCMP may also help alleviate soil acidification and prevent non-point pollution of agriculture caused by long-term mineral fertilizers application in Shajiang Black Soil.
