Sustainable mechanochemical activation of rock phosphate with oxalic acid for high-efficiency phosphorus fertilizers
Abstract
) achieved 79% of the maximum yield while improving phosphorus use efficiency by 58%. This environmentally benign approach valorizes the domestic phosphate resources, reduces fertilizer input requirements, and aligns nutrient release with crop demand. The findings demonstrate the potential of mechanochemical oxalic acid modification as a scalable strategy for producing sustainable, controlled-release phosphorus fertilizers that enhance agricultural productivity and resource efficiency.
