Effects of cattle slurry and cultivation on air exchange in sandy and silty soils from northern Norway
Gas diffusivity and permeability, and air-filled porosity, were measured in undisturbed soil cores at four water potentials between -1.5 kPa and -60 kPa. Virgin (never ploughed) and cultivated sandy and silty soils from two sites in northern Norway were used in the investigation. The cultivated soil...
