Abstract

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

Abstract

Acid mineral soils in Indonesia mostly develop in wet tropical climates supported by high temperatures, so the weathering process runs faster than in dry climate areas. High rainfall causes intensive leaching, so basic cations are lost from the soil layer, and the soil has low base saturation. Some acid mineral soils in Indonesia are farmed under rainfed systems. This soil has a low nutrient availability status compared to irrigated rice fields, due to the lack of water availability, and is still dependent on rainfall. Eco-Enzyme (EE) contains several nutrients and microbes from fermentation that can increase soil fertility. This research aims to determine the effect of EE N nutrient availability and early rice growth in rainfed paddy fields. This study uses a Completely Randomized Design single factor, namely the total bacterial population in EE consisting of 5 treatments, namely K0= control; K1= 8,1 x 106 cells mL-1 in EE; K2= 1,2 x 107 cells mL-1 in EE; K3= 1,6 x 107 cells mL-1 in EE; and K4= 2 x 107 cells mL-1 in EE. Each treatment was repeated 4 times so that there were 20 experimental units. The results of the study show that the provision of the total bacterial population in EE 1,2 x 107 cells mL-1 can increase the pH to 5,38, N-NH4+ to 154,60 mg kg-1, and N-NO3- to 8,26 mg kg-1. Giving total bacteria in EE 1,6 x 107 cells mL-1 can increase the viability of non-symbiotic N2 fixing microbes.

Abstract

Although ultramafic rocks are widespread in Indonesia and have the potential to influence soil properties, studies on the genesis and properties of soils formed from these rocks, especially to understand the characteristics of the lower defining horizon or endopedon, are still limited. This study aims to identify the endopedons formed, which developed from the ultrabasic rocks. This research is descriptive, soil profile points are determined by purposive sampling method by considering that points are true ultrabasic rock distribution. Observations made in this study include observations in the field and observations in the laboratory. The data from the description and laboratory analysis were used as reference for identifying endopedon. Endopedon determination refers to the Keys to Soil Taxonomy 2014 , the twelfth edition. The oxic horizon in Profile-1 is found at a depth of 7 cm to 37 cm from the soil surface with the horizon codes Bo. The Oxic horizon in Profile-2 is located at a depth of 20 cm to 106 cm from the soil surface with the horizon codes Bo1, Bo2. Latosolization is the process that causes the formation of the oxic horizon. The study site is also an area with a wet tropical climate that supports the formation of the oxic horizon.

Abstract

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

Abstract

The issue of acid sulfate soil in Indonesia, characterized by high acidity due to pyrite (FeS2) oxidation, produces sulfuric acid and iron oxide detrimental to agricultural productivity. The use of ameliorants such as coal fly ash (ATB) and empty oil palm bunches (TKKS) is expected to improve soil chemical conditions. The study aims to assess the impact of the ATB and TKKS combination on increasing pH, lowering Eh, and reducing soluble Fe concentration in acid sulfate soils, determining the most effective dose. The research method employs completely randomized design (CRD) with various doses of a combination of ATB and TKKS applied to acidic sulfate soil. Observations focus on changes in pH, redox potential (Eh), and soluble Fe concentration post-treatment. Results of study indicated that application of the ATB and TKKS combination given significant effect to increase soil pH and decreased Eh values. Certain dose combinations exhibit higher effectiveness than single treatments. In conclusion, the combined use of ATB and TKKS offers an efficient and environmentally friendly solution to acidity and iron solubility issues in acidic sulfate soils, supporting increased agricultural land productivity.

Abstract

Ultisol is one type of land in Indonesia that has an area distribution of about 25% of Indonesia's total land area and the widest distribution is in Kalimantan (21.938.000 ha). The acidic pH of the soil causes low availability of P in Ultisol and the occurrence of P fixation by Al and Fe which are positively charged, making P difficult to be available to plants. In this study, ameliorant was added in the form of dolomite and chicken manure to see the effect on Ultisol soil by isothermal phosphate absorption analysis and processed using the Langmuir, Freundlich, and Brunauer-Emmett-Teller (BET) equations. The results of the study concluded that the application of P on Ultisol soil in Gunung Kupang Village, Cempaka District, Banjarbaru City, was in accordance with the Freundlich Equation. High or low P absorption indicates the level of P availability in the soil. In other words, fixation on acidic mineral soils can reduce the amount of P available to Plants.

Abstract

Podzolic soil fertility and health are generally low due to its poor physical and chemical properties. Consequently, the use of organic soil amendments is essential to improve these properties and provide essential nutrients. Palm oil mill sludge solid waste is rich in nitrogen, phosphorus, potassium, magnesium and calcium which makes it a suitable fertilizer. This study aimed to evaluate the effect of palm oil mill sludge solid waste application on the availability of nitrogen, phosphorus and potassium in podzolic soil and corn (Zea mays) production. The experiment was conducted in a pot using a single factor Completely Randomized Design (CRD). The findings showed that application of palm oil mill sludge solid waste to podzolic soil increased the availability of nutrients N-NH4+, N-NO3-, available P and available K and the fresh and dry weight of corn plants. However, it did not increase soil pH. Treatment P4 (20 t ha-1) produced the highest values ​​of N-NH4+, N-NO3-, available P, available K and the fresh and dry weight of corn plants, making it the most effective treatment for the utilization of palm oil mill sludge on Podzolic soil.
