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 matter. Researchshowsthat thedepth ofthe ground water levelpeatsignificantly affectthe availability of nutrientsammonium(NH4+), nitrate (NO3-), P-available, an increasethat occurred ineachparameterwere observed,treatmentis bestfoundat a depth ofground water level60-70cmcomparedto thedepth ofthe ground water level40 - 50cmand80 - 90cm.
