Abstract Different drought-resisting measures were adopted in red soil sloping field. In this paper, downslope farming is taken as CK and the influence of different drought-resisting measure, i.e., terraces, pit and pin hole, on nutrient were analyzed. The results showed that pit had the better effect on soil organic matters, total nitrogen and total phosphorus than pin hole and terrace. Pin hole was the best in improving the mass fraction of total potassium. Compared with downslope farming, terrace did not improve soil total phosphorus mass fraction. Pit on the improvement of available nitrogen and available phosphorus capacity was better than the pin hole and the available potassium contrary. Terrace increased the mass fraction of available phosphorus, available nitrogen and potassium mass fraction decreased.
