Abstract

Characteristics of the most prominent former coal mining land are severe damaged land, causing decreased soil productivity, erosion and sedimentation, soil movement and resulting in land slides, and soil compaction so that it is difficult to process. Efforts to improve the physical properties of coal mining reclamation soils, namely by adding biochar and compost. Biochar and compost can improve the physical properties of the soil by increasing the content of organic matter, total pore space, water content and reducing the weight of soil volume. This study uses a complete random design with 6 treatments and 4 replications. The treatment used in this study is B0 without treatment (control); B1 15 tons/ha biochar oil palm shells; B2 10 tons/ha biochar oil palm shells and 5 tons/ha of city waste compost; B3 7.5 tons/ha biochar oil palm shells and 7.5 tons/ha of city waste compost; B4 5 tons/ha Biochar palm oil shell and 10 tons/ha of city waste compost; B5 15 tons/ha of city waste compost. The observed variables are the content of organic matter, the weight of soil volume, total pore space, soil water content in several PF values, plant height, plant yields and the number of plant pods. The results obtained that the treatment combination of 7.5 tons/ha of biochar oil palm shells 7.5 tons/ha of city waste compost is the best composition to improve the groundwater content of coal mining reclamation. Furthermore, the provision of 15 tons/ha of city waste compost has effectively improved soybean yield. Keywords : biochar, compost, some physical properties, coal, soybeans

Abstract

Oil palm cultivation is increasingly carried out on suboptimal land, such as Ultisols. Application of ameliorant such as biochar and compost may be chosen as an alternative to solve the problem occurred on this sub optimal soil. This study aims to determine the optimal dosage of a mixture of oil palm empty fruit bunch (EFB) biochar, poultry manure compost, and Rock Phosphate (RP) to enhance soil quality and support the growth of one-year-old oil palm plants. The study was conducted over six months in a one-year-old oil palm plantation located in Panca Mulya Village. A randomized Complete Block Design (RCBD) was employed with the aplication of biochar, compost, and rock phosphate (RP = Togo Rock Phosphate, 33.5% P₂O₅) in the following treatments: P0 = control (no treatment); P1 = biochar 20 tons.ha-1 + RP 200 kg.ha-1; P2 = biochar 10 tons/ha + compost 10 tons.ha-1 + RP 200 kg.ha-1; P3 = compost 20 tons.ha-1 + RP 200 kg.ha-1; P4 = biochar 20 tons.ha-1 +compost 10 tons.ha-1 + RP 200 kg.ha-1; P5= biochar 10 tons.ha-1 + compost 20 tons.ha-1 + RP 200 kg.ha-1. Results indicated that the application of biochar, compost, and RP, whether individually or in combination, enhanced oil palm growth compared to the control. The application of biochar and compost improved soil physical properties, increased soil organic matter content, total pore space, available water content, reduced bulk density, soil penetration resistance, and promoted oil palm growth. The best treatment was found to be 10 tons.ha-1 biochar + 20 tons.ha-1 compost + 200 kg.ha-1 RP. Keywords: ameliorant, empty fruit bunch, soil quality
