Abstract

The common problem of acid sulfate soil is its acidity that very low which affect on the availability of nutrients. Due to of that, this study was conducted to identify the effect of Pleurotus ostreatus substrate compost on the chemical properties of acid sulfate soil. The greenhouse experiment was arranged in completely randomized design (CDR) with five treatments, i.e. 0 (b0), 5 (b1), 10 (b2), 15 (b3), and 20 (b4) ton.ha-1. The highest value of pH (5.05), available N (1.70 ppm and 2.13 ppm, ammonium and nitrate, respectively) and organic-C (3.45%) was found in the b4 treatment. Compared to control, the b4 treatment improved about 40.50%, 77.50%, and 40.82% for ammonium, nitrate, and organic-C, respectively. While, the highest available P (16.36 ppm) was found in the b3 treatment, it is improved about 166.88% compared to control (b0). Application of Pleurotus ostreatus substrate compost was able to ameliorate the chemical properties of acid sulfate soil.
