Pengaruh Cara Pemberian Kompos Kulit Durian pada Tanah Sawah terhadap pH, P-tersedia, Al-dd dan Serapan P serta Pertumbuhan Tanaman Padi (Oryza sativa L.)

Abstract

This experiment studied the influence of treatment method of durian husk compost on flooding soil to pH, available P, exchangeable Al, P-absorbtion and growth of paddy, flooding soil sampel (0-20 cm) taken from Pardamean village in T.Morawa subprovince of Deli Serdang. Experiment design used a randomized block factorial with two factor. The first factor is treatment of durian husk compost Og (Co) dan 50g (C), and second factor is compost incubation on field capacity condition (WI) and flooding soil (W2), with eight replication. Combination treatment mixed in soil of experimental unit, and incubated in fourtyfive week. After that, analysis of soil was done in laboratory and seed plantation, analysis in laboratory is exchangeable Al determined with IN KCI exitaction, available P used bray 11 method P-absorbtion used wet destruction method and pH(HO) measured with pH meter. Plantation done by planting 5 seed pot, after 21 day done seldom by to leave 3 crop which its growth is well. The treatment method of durian husk compost on flooding soil, can decrease exchangeable Al, and increased available P, pH and durian husk compost through organic compounds so that P become available.
