To investigate the acid sulfate soil-adapting strategies of South Kalimantan local rice varieties, their rhizoplane pH was preliminarily examined using a glass-made micro-electrode. Although raw acid-sulfate soils in paddocks in South Kalimantan were generally pH 3.5-4.5 and sometimes pH 2.5, pH values of the rhizoplane of living roots directly measured by the microelectrode always converged to approximately 7.0 (variance 0.02-0.22, n=10). On the other hand, the pH of dead roots, which was… CONTINUE READING
