Abstract

The purpose of this research was to know the effect of giving compost in sub soil (over burden) nickel mine toward chemical properties of soil and growth of sengon crop seed in an effort for introduce initial condition of the growing environment for sengon crop, so that earned seed for support revegetation activity of land ex minning.  The research was arranged in Randomized Block Design (RBD) with single factor scheme for 7 treatment degree, that is A0 (without compost), A1 (125 g compost polybag-1), A2 (250 g compost polybag-1), A3 (375 g compost polybag-1), A4 (500 g compost polybag-1), A5 (625 g compost polybag-1) and A6 (750 g compost polybag-1). The treatment reapet for 3 times so that has 21 unit tried. Every experiment unit from 9 crop so that all over has 189 crop. Variable with observed are chemical properties of soil (pH, cation exchange capacity (CEC), N-total, available P and available K) and sengon crop growing (increase high crop (cm), total leaf stalk (stalk), stem diameter (cm), ratio root tip of a leaf and index quality of seed).  The research shown that compost fertilizer giving toward chemical properties of sub soil (over burden) nickel mine raising of value for soil pH, CEC, N-total, available P and available K. However, compost giving toward sengon growth only show effect more real the increase high crop in age 45 hst. Key Word : Chemical properties of soil, compost, growth of sengon crop.

Abstract

Utilization of climatic information and physical characteristics of the soil to determine the soil water balance in agriculture is a very important factor because it relates to the planning model of activity to be undertaken. This is important because the output is known a periods of surplus and deficit water of the regions. Periods of surplus and deficit is implications for the length of growth period available to facilitate the planning of agricultural models that will be developed. The planning agricultural model is still oriented to the needs of farmers and the willingness of the government, not based on the climatic information and physical characteristics of the soil. Keywords : climatic information, soil characteristics, water balance.
