The general obstacles in cultivating rubber and oil palm are soil acidity and limited availability of nutrients, especially N, P, and K. These nutrients play an important role in the growth of rubber and oil palm plants. Knowing the nutrient content is necessary to be able to determine the management that needs to be carried out. The objective of this study is to determine differences in the nutrient content of N, P, and K on various lands planted with rubber and oil palm plants. Soil sample analysis was conducted in the laboratory for available N, available P, and available K. To determine differences in land use for the elements N, P and K, data were analyzed using an unpaired two sample t test. The results showed differences in available K and available P levels between the two land types, while no differences were observed in N availability between the two land types. This variation may be caused by differences in land management practices.

Endopedon identification is very necessary to determine the development, physical and chemical properties of soil. The development of endopedons originating from ultramafic rocks around Kiram Village, Karang Intan District, Banjar Regency has not been studied much, therefore it is necessary to explore more about the results of soil development. This research was a descriptive method to identify diagnostic horizons that develop in the endopedon. South Kalimantan is one of the areas where ultrabasic rocks are distributed and is an area with a wet tropical climate. The weathering force of the parent material will be faster in the wet tropics. Ultrabasic rocks in each region have different mineral and chemical compositions. Based on the research results, the Oxic horizon in Profile-1 was found at a depth of 29 cm to 76 cm from the ground surface. While in Profile-2 the Oxic horizon was found at a depth of 19 cm to 110 cm from the ground surface. The formation of the oxic horizon is due to the Latosolization process. Such as the long laterization process is supported by environmental conditions, climate, and rainfall making this laterization process will be better.

Peat soils contain high concentrations of organic nitrogen, but in a form that is not available to plants. South Kalimantan has NH4+ in the range 4.51- 736.86 mg.kg-1 and NO3- content is in the range of 0.37-54.69 mg.kg-1. The low availability of N nutrients in peatlands is due to the slow nitrogen mineralization process and the very high mobility of N in the soil. This study aims to determine the effect of the composition of peat and chicken manure on nitrogen mineralization. This study used a single factor in completely randomized design (CRD) with 5 treatments and 4 replications. carried out in greenhouses and in the Soil Laboratory of the Faculty of Agriculture, Lambung Mangkurat University, Banjarbaru. The treatment is the composition of peat and chicken manure, namely 100% peat material, 80% peat material + 20% chicken manure, 60% peat material + 40% chicken manure, 40% peat material + 60% chicken manure, 20% peat material + 80% chicken manure. The best composition for nitrogen mineralization is based on the high nitrate content, which is found in the composition of 80% peat soil + 20% chicken manure in the first month of incubation, and on the composition of 80% peat soil + 20% chicken manure in the second month. This composition is the best composition from a combination of peat material and chicken manure against nitrogen mineralization in the form of nitrates.

The mining process can result in the mixing soil (post-coal mining soil) that tends to have low nutrient content, such as nitrogen, phosphorus, and potassium, which are crucial for plant growth. Additionally, the water flow in post-coal mining soil is often disturbed. The coal mining process can damage the soil structure and affect its ability to absorb water. The purpose of study is to examine the impact of palm boiler ash (PBA) and chicken manure fertilizer influence on soil pH, bulk density, and permeability, as well as the concentrations of total nitrogen, total phosphorus, and total potassium. The research method used a Completely Randomized Design with two factors: PBA (0 t ha-1, 5 t ha-1, 10 t ha-1) and chicken manure (0 t ha-1, 10 t ha-1, 20 t ha-1). The research findings show that applying PBA fertilizer and chicken manure impacts pH, bulk density, permeability, total nitrogen, total phosphorus, and total potassium from chicken manure. The application of 10 t ha-1 PBA and 20 t ha-1 chicken manure showed the best treatment that could increase the permeability, pH, total P and K of the soil

The slope is one of the important elements in topography that affects various natural processes and human activities. Slope position can lead to reduced soil fertility due to runoff. This research aims to analyze the comparison of water-stable aggregate on different slope positions which are divided into three, namely between upper slope, middle slope and lower slope. The research method used is descriptive comparative, which is carried out by deliberate sampling on sloping land planted with rubber plants with a depth of 0-20 cm and the same slope of 25-45% and then analyzed in the soil laboratory. Data were analyzed by t-test to determine the comparison of water-stable aggregate different slope positions. The results showed that water-stable aggregate values at different slope positions had significant differences. Water-stable aggregate values in the upper slope tend to be smaller than those in the middle slope and lower slope which are much larger. Slope position, organic-C content, and clay fraction affect water-stable aggregate values
