Responses of (a) soil nitrate nitrogen content (NO3--N) and soil ammonium nitrogen content (NH4 + -N), and (b) available soil phosphorus to the variation in rainfall amounts and dry intervals. The values at each dry interval are the means ± SE (n = 4). Capital letters indicate significant differences (p < 0.05) between rainfall amount treatments and small letters between dry interval treatments
