Management of phosphorus in farmland for healthy soil cultivation
The relationship between phosphorus nutrient management and soil health in farmland ecosystems is systematically sorted out,and the current status and problems of phosphorus fertilization in farmland soil in China are summarized.From the perspective of health soil cultivation,it is proposed to scientifically manage phosphorus nutrient resources,explore and make use of functional microorganisms related to soil phosphorus cycle,and build a phosphorus nutrient resource management technology system based on different soil conditions,crop types and environmental factors,aiming to improve the bioavailability and utilization efficiency of phosphorus,promote nutrient recycling,reduce soil phosphorus loss and avoid non-point source pollution.Management of phosphorus nutrient resource in farmland,including the development and application of new type phosphate fertilizers,can help maintain and increase crop yields,improve farmland soil health,and provide scientific and technological support for maintaining national food security and promoting the sustainable development of agricultural production.
