Abstract
Pyrite is almost exclusively present in the reduced zone of acid sulphate soil profiles. This pyrite is believed to interfere with determination of C org in the soils by the wet combustion method using Cr2O7(2-). A study was conducted to determine an accurate and reliable method for estimation of C org in acid sulphate soils in Malaysia containing variable amounts of pyrite. Some of the established methods of carbon (C) determination were tested against Carbon Determinator (Leco IR-312) which was regarded as the standard method. It was found that the interference of pyrite in the determination of C in acid sulphate soils by wet combustion was minimal. The total oxidation procedure was found to be the most reliable and accurate method for determination of C org in acid sulphate soils in the absence of Carbon Determinator. The Walkley-Black method underestimated while the loss on ignition method overestimated the C org content in the soils
