Abstract

The change from forest to oil palm plantation probably changes the distribution of phosphorus (P) fractions in the soil. This study was aimed to evaluate the soil top layer P fractions, collected in forest and oil palm plantation in Jambi, as well as their correlation with soil chemical properties. Soil samples were collected in top layers of forest and oil palm plantation. Some soil chemical properties and P fractions were analyzed. The P fractions analyze were conducted according to Tiessen and Moir method. The results showed that the moderately labile P fractions namely  NaOH-Porganic (-Po ) and -Pinorganic (Pi) were the dominant fraction in forest soil and oil palm plantation as well. The forest had a higher percentage of avaliable P (resin-Pi, NaHCO3-Pi,-Po) and organic moderately labile P (NaOH-Po) compared to those of oil palm plantations in their total fractions analyzed. As for NaOH-Pi, oil palm plantation had higher amount of this fraction compared to that of forest. This means that naturally the change from forest to oil palm plantation changed the P fractions distribution due to the changes of organic carbon (C) content. The correlation test showed that almost all P fractions significantly correlated with organic C indicating that the mineralization of organic C affecting the P fractions distribution, suggested that organic C controlled the P fractions distribution in the top soil of forest and oil palm plantation.
