Leves trench tillage can retain runoff, decrease soil wash and nutrient loss, increase utilization rate of soil water, and further increase crops yield.
水平沟能够显著地拦蓄径流，减少土壤冲刷和养分流失，提高土壤水分利用率，进而提高作物单产。
In addition, conservation tillage could reduce the nutrient loss of the soil.
另外，保护性耕作地能够减少农田土壤养分损失。
The amounts of nutrient loss were in direct proportion to rainfall intensity.
养分流失量与雨强成正比；
The invention relates to a puffed leisure food, in particular to puffed pumpkin chips with less nutrient loss and easy digestion, and a preparation method thereof.
本发明涉及一种膨化休闲食品，尤其是涉及一种营养物质损失小，且易于消化的膨化南瓜片及其制作方法。
Sloping spatial distribution of soil nutrient loss responds to spatial distribution of soil erosion patterns erosion intensity. Shallow gully ditch is the severest position of soil nutrient loss.
坡面土壤养分流失的空间分布与坡面侵蚀方式和侵蚀强度的空间分布相一致，浅沟沟槽是坡面土壤养分流失最严重的部位。
Studies have shown that the soil nutrient loss has strong connection with its content, and the accumulation of soil nutrient can increase the loss potential.
农业面源污染物质氮、磷流失是与土壤营养物含量之间存在较强的联系，土壤营养物的累积可增大流失风险。
