Abstract: This studyaims to
determinethe effect ofthe depth ofthe ground water leveland thesoilorganic
matterand obtainthe combination ofthe depth ofthe ground water levelto the type
oforganic matterthat isbestfornutrient availabilityandgrowthof oil palm
plantationson peatlands. This research was conductedusing Split PlotDesign, the
mainplotisthe depth ofthe water tableandthe subplotis thetreatment oforganic
