Sammanfattning

A 13-year long-term experiment on the Loess Plateau of China was used to evaluate the effect of two different fertilizer regimes on the soil's physical/hydraulic properties. The fertilizer regimes included (i) control without any fertilizer (C), (ii) applications of chemical fertilizer (NPK), and (iii) applications of chemical fertilizer plus dairy manure (MNPK). Undisturbed soil cores were collected from the field to determine soil water retention curves and hydraulic conductivity (saturated and unsaturated). In addition, gravimetric water content, soil bulk density, porosity and saturated hydraulic conductivity were measured several times during the crop growing season to check seasonal variations. Annual application of manure increased soil water retention at the two soil depths tested (0-5 and 10-15 cm) relative to the control treatment (P
