soil nutrient content

基本解釋

Cereal crops can all-sides improve soil nutrient content.
谷類作物能較全面地改善土壤的養(yǎng)分含量；
Tillage treatments affect soil nutrient in soil profile, soil nutrient content, and fertilizer use ratio.
不同耕作處理能影響土壤養(yǎng)分的剖面分布和養(yǎng)分含量及肥料的利用效率。
In addition, rational fertilization can maintain the soil fertility of artificial forest land of Pinus kesiya var. angbianensis and even raise the soil nutrient content of the forest land.
此外，合理施肥能夠保持思茅松人工林地的土壤肥力，以至提高林地土壤的養(yǎng)分含量。

Dr Bowden and his colleagues also hope to understand the impact of thermokarst activity on the structure of the soil, and its nutrient content.
