Abstract

One of the prospective places for agricultural usage in acid sulfate rice fields, which are typically spread out in lowland areas along coastlines that occasionally undergo flooding. If handled effectively in accordance with the issues found in the land, this site can be developed as a productive agricultural region. Agricultural development on acid sulfate soils frequently encounters a number of issues, including (pH) acidic soil, high iron content, a lack of phosphate availability, and the presence of pyrite (FeS2). In this study, the relationship between P availability, Fe solubility, the Fe-P fraction, pH, Eh, and pyrite depth in acid sulfate paddy fields will be examined. Purposive sampling was used in field research utilizing the survey method in the acid sulphate rice fields of Barito Kuala Regency. This research was based on the distribution map of Fe solubility in Barito Kuala Regency. The results of this study indicate that there are three variables that have a significant effect on P availability: soluble Fe amd Fe-P fraction with the power regression form and a very strong relationship; and soil pH with a linear regression form and a strong relationship. Pyrite depth and soil Eh had no significant relationship with P availability in acid-sulfate lowland rice fields.

Abstract

The study aimed to determine the effect of application fertilizer derived from animals (manure) or plants (green manure) on the supply and absorption of plant N, changes in pH, CEC, and suppressing Al solubility and to determine the best type of organic matter in supplying and absorbing plant N, change in pH, CEC, and suppress Al solubility. This study was carried out in the field and arranged using a single factor completely randomized design (CRD). The treatments applied in study were K0 = control, K1 = cow manure (50 g pot-1), K2 = goat manure (50 g pot-1), K3 = chicken manure (50 g pot-1), K4 = green manure for weed hair buns (50 g pot-1), K5 = rice straw green manure (50 g pot-1), K6 = gamal green fertilizer (50 g pot-1). The application of various organic materials can increase pH, CEC, available N, plant dry weight, N uptake of corn plants, and reduce Al solubility.

Abstract

Land degradation is a major environmental issue that reduces soil productivity and impairs ecological functions. Kalibeluk Village, Batang Regency, has diverse biophysical characteristics that may result in varying levels of land degradation. This study assessed land degradation potential and the corresponding degradation status in Kalibeluk Village, using GIS-based spatial analysis supported by field verification and laboratory assessment. Spatial analysis was conducted using soil type, slope gradient, rainfall, and land use parameters through an overlay technique to determine land degradation potential. Field verification and laboratory analyses were subsequently performed for each Land Mapping Unit (LMU) to evaluate land degradation status based on Government Regulation of the Republic of Indonesia Number 150 of 2000 and Regulation of the State Minister of Environment Number 07 of 2006. The results classified land degradation potential into three categories: low (71.481 ha; 39.8%), moderate (104.167 ha; 57.9%), and high (4.137 ha; 2.3%). Evaluation of land degradation status indicated that LMUs with low and moderate degradation potential were categorized as Slightly Degraded (R.I), whereas LMUs with high degradation potential were categorized as Moderately Degraded (R.II). The main limiting factors were soil fraction composition, water permeability, redox conditions, and surface rockiness. The findings demonstrate that GIS is an effective tool for identifying land degradation levels and supporting land management planning. Recommended rehabilitation measures include agroforestry, cover crops, terracing, the application of organic matter and soil amendments, and conservation drainage systems to improve soil quality and reduce land degradation risks sustainably.
