Abstract
Calcium sulfate, a common soil amendment was applied at rates of 0, 1,000 and 2,000 kg ha-1 to flooded rice plots treated with urea-N (128 kg ha-1). Experimental plots were drill-seeded with Toro-2, a mid-season long-grain rice cultivar, and CH4 emissions were measured over the first cropping season. Over the 70 d sampling season, the low and high rate of CaSO4 reduced CH4 evolution 29 and 46%, respectively, compared to control plots. No significant correlation between soil temperature (0, 5, 10 cm depths) and CH4 emission was observed.
