Abstract:

Leaching from soil nutrients is important reasons leading to losses of soil nutrition elements. Nutrient leaching is a serious problem, not only will cause nutrition losses and reducing fertilizer use effiency, but also pollute ground water, and bring about bad environmental impact. Therefore, leaching of fertilizer nutrients from agricultural soils has been attracted more attention, whether from an agricultural view, or from an environmental one. This paper reviewes the research progress and trend of the leaching of fertilizer nutrients from agricultural soils at home and abroad, illuminates the forms and mechanism of the leaching loss of N, P, K nutrients from agricultural soils, as well as its affecting factors, and points out the existing problem and future direction of domestic research on the leaching of fertilizer nutrients from agricultural soils.
