Abstract

Indonesia is a coal producing country and coal mining activities are carried out using the open pit method. The activity resulted in the acid mine drainage (AMD). AMD has low pH and contains high concentrations of heavy metals ions such as aluminum (Al), iron (Fe) dan manganese (Mn). One of the interesting technologies in the AMD treatment is passive treatment using constructed wetland. The system can increase pH and reduce level of dissolved metals. Oil palm empty fruit bunches (OPEFB) are potential to improve soil pH, because they have a high nutrient content such as N, P, and K. This study aims to determine the effect of OPEFB as amendment material on artificial wetland media on pH, Fe, Mn in AMD management. The method used was a single Randomized Complete Design with the treatment of OPEFB of 0, 100, 200, 300, and 500 g 5.5 kg-1 soil then replicated four times. The results showed that oil palm empty fruit bunches high significant increase in pH, Fe, Mn and 100 g 5.5 kg-1 soil doses effectively used for the AAT management by passive treatment as fulfilled the mining liquid waste quality standards according to the Ministerial Decree State of the Environment Number 113 of 2003 and South Kalimantan Province Governor Regulation Number 04 of 2007.

Abstract

Organic matter application and water management were frequently applied to prevent the oxidation of pyrite in acid sulfate soils. The purpose of this study was to determine the effect of cow manure application with varying height of inundation on soil pH, soluble-Fe, and available P of acid sulfate soils. This study employed factorial treatments and in a completely randomized design. The first factor was the dosage of cow manure: 0, 10, and 20 t ha-1, while the second factor was various water depths: 5, 10, and 15 cm. Results of study showed that the interaction of cow manure and water depth did not affect soil pH, but single factor of the treatments (cow manure and water depth) significantly affected soil pH. The interaction of cow manure and water depths did not significantly decrease the solubel-Fe in the fourth week. The interaction of cow manure and water depths significantly increased P-availability in the fourth week. Results of this study demonstrated that cow manure application and water depth improved soil pH and P-availability of acid sulfate soils.

Abstract

Soil acidity (pH) is the main obstacle in tidal swampland. The high soil acidity (pH < 4.0) causes an increase in the solubility of iron (Fe). The high soil acidity affects the balance of chemical reactions in the soil and the availability of nutrients in the soil. The purpose of this study was to determine soil acidity (pH), redox potential (Eh), and soluble Fe at at varying soil depths with different pyrite locations in tidal swampland. This study used a nested design and studied the following factors: 1) Depth of pyrite 0-50 cm layer (actual acid sulfate soil) and 50-100 cm layer (potential acid sulfate soil). 2) Soil depth includes 0-25 cm, 25-50 cm, 50-75 cm, and 75-100 cm. Soil samples were taken at the depth where pyrite was detected, with 3 replicates at each soil depth. This resulted in a total of 24 experimental units. The depth of the nested soil coincided with the depth of the pyrite. The study analyzed the acidity of acid sulphate soil, redox potential, and dissolved Fe at pyrite locations within soil depths of 0-100 cm and 0-25 cm, 25-50 cm, 50-75 cm, and 75-100 cm. The results indicate that there was no significant difference in the measurements between the various soil depths of 0-50 cm and 50-100 cm.

Abstract

The level of solubility of aluminum and iron metals in the soil is one of the post-coal mining land problems. The high solubility of Al and Fe can be toxic to plants, so that plants are difficult to grow. This study aims to reduce the solubility of Al and Fe using formulations of liming, organic matter, and NPK fertilizer and to examine their effects on the growth and height of corn in post-coal mining land. The study used a Completely Randomized Design (CRD) with a single factor of ameliorant formulation. The treatment consisted of 10 treatments and was repeated three times, so there were 30 experimental units. The results showed that the application of ameliorant formulation of liming, organic matter, and NPK fertilizer had an effect on decreasing the solubility of Al and Fe in the soil and increasing the growth of corn in post-coal mining land. Soil that has been applied with K1 treatment (lime 3 t ha-1) can give the best results in reducing the solubility of Al and Fe metals in the soil. Application K2 treatment (giving organic matter 10 t ha-1), gave the best results for increasing the growth of corn in post-coal mining land. The best treatment for reducing Al and Fe soluble and increasing plant height growth was found in the treatment of lime 3 t ha-1 + organic matter 10 t ha-1 + NPK fertilizer 50 kg t ha-1, which was 0.42 (me 100g soil-1), 4.48 (ppm) and 108 (cm). The conclusion of this research is that the application of lime formulations, organic materials and NPK fertilizer is able to reduce levels of Al-dd, soluble Fe in the soil and increase the height growth of corn plants. Dolomite is able to reduce Al-dd and Fe-soluble levels. The application of organic and inorganic fertilizers affects the growth of corn height.

Abstract

Ultisol has problems such as soil acidity <5.5, high Al saturation >42%, low organic matter <1.15%, low nutrients such as 0.14% N, P 5.80 ppm, and low base saturation < 35%. Chicken manure is an organic material that alters soil pH and increases total N, total P, and P uptake. Coffee grounds can increase pH, N nutrients, organic matter, available P, prevent fungal growth. The purpose of this study was to determine the effects of feeding chicken manure and coffee grounds compost extract in increasing pH, increasing N availability, decreasing exchangeable Al, and increasing P availability of Ultisol. The research method used was a one-factor Completely Randomized Design (CRD). Factors tested were chicken manure, coffee grounds compost extract, and a combination of the two up to five treatments. K0 = Control, no chicken manure and coffee grounds compost extract; K1 = Coffee grounds compost extract 4 kL ha-1; K2 = Chicken manure 2 tons ha-1; K3 = Chicken manure 2 tons ha-1 + coffee grounds compost extract 4 kL ha-1; K4 = Chicken manure 4 tons ha-1 + coffee grounds compost extract 8 kL ha-1. Each treatment was replicated four times for 20 experiments. The results showed that the application of chicken manure and coffee grounds compost extract decreased soil pH, and soil exchangeable Al and increased soil ammonium, nitrate and available P levels.

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.
