Evaluation of Soilproperties In Some Soil and Water Concervation Techniques in Oil Palm Plantation. The purpose of this study to determine the most appropriate concervation tecniques used in oil palm plantationsintherepairofsoilproperties. ThisstudywasconductedfromApril2013toFebruary2014in the Bangun Estate, PTPN III Simalungun district, North Sumatra Province. This study using a randomized block desing (RBD) nofactorial with treatmentfactors, consisting of; VM: Vertical Mulch,
CB: Compost Biopori, CD: Concave Disc, PG: Planting Grass. The results show (1) the treatment of concervation techniques concave disc with compost bioporifoundsignificant effect on soil water content. The best treatment to the amount o f moisture contained in the compost treatment biopori. (2) In the treatment of concervation techniques for disk concave vertical mulcing, planting grass, compost treatmentandplantinggrass, bioporifoundarealinfluenceonthepermeabilityofthesoilprofil, whichin the best treatment to thepermeability ofthe soilprofile contained in the treatment ofgrassplanting. (3) The treatment technique implemented concervation in oil palm plantation did not significantly affect organic C, Total-N, C/N, Bilk Density, infiltration, levels ofN, P, K in the leaves.
