Nilai Zero Point of Charge (ZPC) serta hubungannya dengan erapan kalium pada tanah gambut Pantai Jambi dan Kalimantan Tengah

Abstract

One of the important chemical aspect is peatland management which has not been paid attention to is Zero Point of Charge (ZPC). By determining soil ZPC value, the sorption and bounding of cations can be estimated in certain pH value. Low of Kalium (K) is the one of other problems of peatland. This nutrient is easily leaching from peat because of the weakness bounding. This research is aimed to determine ZPC value, maximum sorption of K and bounding form of K being contained by the coastal peats of Jambi and Central Kalimantan with decomposition degrees of sapric, hemic, and fibric.
