人们认为，长期耕种可耕种作物的土壤和不施有机肥会降低作物生产所需的土壤质量。我们研究了来自有机奶牛场的两种砂壤土的孔隙度，并将它们分别与常规管理的只种植农作物的奶牛场和只种植矿质肥料的耕地进行了比较。测定了土壤耕层的饱和导水率、持水特性、空气扩散率和透气性。
Long‐term cultivation of soils for arable crops and without application of organic manure is thought to reduce the soil quality for crop production. We studied the porosity of two sandy loam soils from organic dairy farms with a ley cropping system and compared them with a conventionally managed dairy farm growing arable crops only and an arable soil receiving only mineral fertilizers, respectively. Saturated hydraulic conductivity, water retention characteristics, air diffusivity and air permeability were determined in the plough layer of the soil.
