Abstract

Ultisol is a soil that contains low nutrients N, P and K and has the potential for Al-poisoning. Ultisol also has a low Cation Exchange Capacity, acidic soil pH and is sensitive to erosion. Improvements need to be made to increase Ultisol productivity, one of which is by adding organic ingredients. In addition to sugarcane bagasse compost, chicken manure contains many benefits because it contains a lot of organic materials that are good for the soil and plants. Increasing soybean yield is one of the priorities and can be done by utilizing Ultisol land. The purpose of this study is to determine the effect of composting a mixture of bagasse and chicken manure on ultisol fertility and soybean crop production. The research method carried out is experimental by conducting initial analysis of soil samples, compost application, maintenance, harvesting, soil analysis after compost application, calculation of height and crop yield. The results obtained were that the application of mixed compost of bagasse and chicken manure did not have a real effect on soil pH, P-available and Aldd, but could increase soil pH and P-available and lower Aldd in the soil. The application of mixed compost of bagasse and chicken manure was significantly different from plant height and was very different for soybean yield with the highest crop P3 (average plant height of 84.678 cm) and the highest yield of P3 3.938 tons/ha. The recommended treatment for soybean plants is P3 treatment with a dose of 15 tons/ha.

Abstract

Low infiltration is one of the limiting factors on suboptimal land for agriculture. The infiltration is closely related to the soil's available water for plants. Low infiltration impacts soybean productivity. The contour planting system is a soil and water conservation technology that can be applied to increase infiltration. This research aimed to examine the impact of modifying the contour planting system on the infiltration characteristics of suboptimal land and soybean yields. The research used a quantitative approach with experimental methods (split-plot design) and three replications. The main plot treatment was the position of the land on the slope (the upper, middle, and lower). The subplot treatment was the contour planting system (standard contour planting system, 30o, 45o, and 60o from the contour line). Data were analyzed using analysis of variance and Duncan’s Multiple Range Test. The results showed that the modification of contour planting systems had no significant effect compared to the standard contour planting system in improving organic carbon content, bulk density, infiltration characteristics, and soybean plant height. The standard contour system resulted in higher soybean yields than the modification of the contour planting system. The position of the soil had a significant influence on soil properties, infiltration characteristics, plant height, and yields of soybeans. The soil characteristics, infiltration characteristics, and soybean yields resulting from standard and modification of contour planting systems showed suboptimal improvements. Therefore, further studies are needed to optimize the application of modification of contour planting systems to support the implementation of conservation agriculture systems.

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

Abstract

Peatlands naturally function as water storage, water supply, and water controller. However, if they are not managed properly, this can cause changes in the water system or hydrology, especially fluctuations in groundwater levels. The decline in groundwater levels in peatlands triggers oxidation and subsidence, especially during the dry season. One effort that can be made to control this decline is to carry out a water balance analysis, which will provide a spatial and temporal understanding of the water's condition. This research was carried out in the Mangsang area at HTI PT. Rimba Hutani Mas, Merang District, Bayung Lencir District, Musi Banyuasin Regency, South Sumatra. The research was carried out by the survey method using the Thornthwaite & Mather Water Balance method. The data used included dimensions of drainage channels, rainfall, temperature, ground water level, and canal water level. The calculated data consisted of average monthly rainfall, average monthly air temperature, potential evapotranspiration, accumulated potential water loss, available water capacity, monthly differences in soil moisture storage, actual evapotranspiration, deficit, surplus, and direct runoff. The research results show that in the Mangsang area of ​​PT. Rimba Hutani Mas, there was a water surplus in March, April, November, and December and a deficit in January, February, May, June, July, August, September, and October. Although the calculation results indicate that water-deficit months occur in January, February, May, June, July, August, September, and October, this research area has been anticipated to avoid groundwater level fluctuations through effective water management and the construction of canal blocks.
