Abstract

Reclamation of ex-mining land is important in restoring environmental conditions approaching the original soil conditions before mining. The aim of this study was is to observe the effect of organic matters and organic matter placement on soil fertility in an effort to improve growth of Merbau (Intsia spp. (L bijuga, L palembanica) and Sengon Buto (Enterolobium cyclocarpum) trees. The study was conducted on a former mining land area of PT. Bukit Asam, South Sumatra. The experimental design used in this study was factorial randomized block design with organic matter factors and organic matter placement. Parameters used for evaluating soil fertility were pH, Al-dd, H-dd, C-organic, total-N, available-P, potential P and K. Parameters of tree growth measured were height, diameter, number of leaves and number of branches and roots. The results showed that organic matter had significant effect on soil fertility and could increase the rate of tree growth and root development. The use of oil palm empty fruit bunch compost significantly increased soil fertility. Results of this study explained the positive relationship between soil fertility with the growth of young trees.

Abstract

Ultisol is one of soils type in Indonesia which has several problemsr for the cultivation of plants such as low pH, high Al saturation, low content of organic matter, and limited water storage. The objective of this study was to investigate the effect of zeolite and compost application on water retention, cation exchange capacity, and growth of sorghum at an Ultisol. The study was conducted using a completely randomized factorial design with two factors, the first factor was zeolite doses with five levels consisting of Z0 (no zeolite), Z1 (20 t ha-1), Z2 (40 t ha-1), Z3 60 t ha-1), Z4 (80 t ha-1) and the second factor is variation of compost dosage with three levels consisting of K0 (no compost), K1 (compost 3%), K2 (compost 6%) Each treatment was repeated three times. The results showed that in the treatment of zeolite 80 t ha-1 water retention increased by 13,7% and in the treatment of compost 6% reached 13,76% but there was no interaction between zeolite and compost to water retention. The increase of water retention was due to the increase in C-organic and porosity and the decrease of soil bulk density. The application of zeolite and compost succeeded in increasing the cation exchange capacity at the zeolite treatment of 80 t ha-1 + 6% compost to 17,46 cmol kg-1 due to the increase of soil pH. If zeolite and compost were given in high doses they could increase the growth of sorghum.

Abstract

The existence of industries can cause severe environmental pollution. The impact of environmental pollution can be reduced by phytoremediation by using aquatic plants such as Echinodorus radicans and Pistia stratiotes. This study was aimed to determine the potential of aquatic plants Echinodorus radicans and Pistia stratiotes as lead (Pb) remediators. This study used a completely randomized design with six treatments, i.e. T0F1 (without plant/control 2 ppm), T0F2 (without plant/control 4 ppm), T1F1 (Echinodorus radicans 2 ppm), T1F2 (Echinodorus radicans 4 ppm), T2F1 (Pistia stratiotes 2 ppm), and T2F2 (Pistia stratiotes 4 ppm). The result of this research indicated that T2F2 (Pistia stratiotes 4 ppm) treatment reduced Pb by 92,53% which was higher than T1F2 (Echinodorus radicans 4 ppm) treatment of 89,59%. Pistia stratiotes more effectively reduced Pb content than Echinodorus radicans. Pb contaminated water that was previously used for growing Echinodorus radicans and Pistia stratiotes could be safely used for watering spinach plant (Amaranthus tricolor) to improve its growth
