Soil Nutrient Analysis of High Standard Farmland Construction in Fengxiang Area

Abstract

In order to ensure China's grain output and food security, we should upgrade the grade of farmland, increase farmers' income, and realize the storage of grain in the land and the storage of grain in technology. While promoting the planning tasks of high-standard farmland construction projects issued by the state and Shaanxi Province, through the determination of soil nutrient indicators in the proposed high-standard farmland area in Fengxiang District, it is pointed out that the average content of soil organic matter in the study area was 12.18 g/kg, which was relatively insufficient as a whole; the average content of soil available nitrogen was 149.45 mg/kg, which was relatively abundant as a whole; the average content of soil available phosphorus was 8.94 mg/kg, which was also relatively insufficient as a whole; and the average content of soil available potassium was 124.82 mg/kg. The whole is moderate. To sum up, after appropriately increasing the content of organic matter and phosphorus, the newly built high-standard farmland can meet the demand for soil nutrients for food crop growth and meet the requirements of high-standard farmland construction in Northwest China.
