2) dryland soil
旱地土壤
1.
Effects of soil-surface mulching on organic carbon,inorganic carbon and light fraction organic carbon in dryland soil
不同地表覆盖栽培对旱地土壤有机碳、无机碳和轻质有机碳的影响
3) Upland soils
旱地土壤
1.
Although the averaged P sorption maxima of upland soils derived from Langmuir sorption plot was a little higher than that of paddy soils the potential of P loss from upland soils to waterbodies was greater because upland soils usually had a much higher P level.
旱地土壤中流失的磷是地表水体中磷的重要来源 ,本文通过模拟实验对比太湖地区丘陵旱地土壤和水稻土对磷的吸持解吸特征 ,结果表明虽然旱地土壤对磷的固定能力略高于水稻土 ,但由于旱地土壤的有效磷水平普遍高于水稻土 ,因而前者磷的吸持饱和度 (DPS)要大大高于后者 ,这就决定了旱地土壤中的磷被淋溶或以溶解态随径流流失的风险和数量也显著高于水稻土 。
4) dry land
旱地土壤
1.
The nitrogen leaching loss from the soils in dry land at different depths (20, 40 and 60 cm) of columns was studied.
用土柱研究旱地土壤60cm土体夏季的氮肥淋溶损失，结果表明，在土壤施尿素后35d内淋水350mm，在不产生泾流的条件下，淋失率平均为25。
5) upland soil degradation
旱地土壤退化
6) dryland soil conservation
