Soil from an oxisol from Toradja (Indonesia) was treated with NPK fertiliser at rates of 20, 100 and 200 kg ha −1 . Each sample was subjected to 60 mm of simulated rainfall and analyses made of the run‐off suspension and water, and of drainage, for N0 3 ‐N, P and K. For two storms, separated by a drying period of 10 days, the total losses were 16.8% of the added N, 12.1% of P and 19.6% of K.
