Abstract

Kemampuan gambut dalam menyerap air mempunyai arti penting bagi pengelolaan lahan gambut yang sering digambarkan dengan kurva retensi air menurut fungsi potensial air. Penelitian ini dirancang untuk memahami hubungan antara tinggi muka air dengan kadar lengas tanah gambut. Data tinggi muka air tanah (TMA) yang diperoleh melalui pengukuran langsung di lapangan. Data kadar lengas ditetapkan di laboratorium. Data kadar seratnya dianalisis secara kuantitatif dengan bentuk diagram menurut tipe penggunaan lahan dan tingkat kematangan gambutnya. Hasil penelitian ini mengindikasikan bahwa semakin tinggi muka air gambut semakin jauh dari permukaan tanah diikuti semakin tinggi kadar lengas gambut pada lahan terbuka. Hasil penelitian menunjukkan hasil yang kontradiktif dengan penelitian lain. Hal ini menunjukkan bahwa kadar lengas gambut tidak semata dipengaruhi oleh TMA, karena dapat terkait dengan daya kapilaritas atau ada faktor lain yang mungkin berpengaruh lebih dominan terhadap perubahan kadar lengas gambut

Abstract

Podsolic soil is acidic soil, low nutrient content, especially N, P, K, Ca, Mg. One of the efforts that can be done to overcome this problem in soil is the addition of organic material. The addition of organic material bokashi rice straw and oil palm empty fruit bunches (TKKS) compost can add nutrients in the soil such as nutrients N, P and K. This study aims to determine the effect of rice straw bokashi and oil palm empty compost applied to Podsolic soils. The method used in this study was a single Randomized Complete Design (RAL) with the treatment of dose of 0 t ha-1 (bokashi and TKKS) 3 t ha-1, 5 t ha-1, 7 t ha-1 (bokashi) and 1.5 t ha-1, 3 t ha-1, 4.5 t ha-1 (TKKS). The results of this study indicate that the application of rice straw bokashi and TKKS compost has a significant effect on N-ammonium and P-available.

Abstract

One of the problems in upland soils is poor in nutrient N. One effort to increase the availability of N in the soil is by providing swallow’s droppings which has a high N content. Thus, the purpose of this research was to determine the availability of N on upland soil was by applying swallow manure. This research employed Completely Randomized Design (CRD) with single factors (several levels of swallow’s manure: 0.0; 2.5; 5.0; 7.5; and 10.0 t ha–1). The availability of N in the soil was observed through the experimental column leaching, where 20 g of Ultisols was mixed with 20 g of quartz sand and swallow’s manure on a leaching column of 1-inch diameter and 20 cm height. Mineralized amounts of NH4+ and NO3– from the soil were determined by the percolation method (leaching) in every five days for 25 days. The results showed that the application of swallow’s manure increased the availability of total-N in the soil in the form of NH4+ and NO3–, and produced the release pattern of NH4+ and NO3– which was still relatively high until the end of the testing period. The results of this study demonstrate that application of swallow’s manure may be used as a slow-release fertilizer.

Abstract

Ultisols have the potential to be developed as productive agricultural land, but need several efforts by means of organic matter and fertilizer applications. Biourine is a fermented liquid waste from cow urine. One of the commodities developed in Ultisol is spinach (Ipomoea reptans Poir). The study aims to determine the effect of treatments of six biourin concentrations on available nitrogen, soil pH, and growth plants of spinach on Ultisol soil. The single factor of completely randomized design (CRD) used as an experimental design consists of six treatments with four replications (24 experimental units). The results showed that biourine had no effect on increasing soil ammonium-N and had no effect on soil nitrate-N and soil pH. Biourin affects the increase in wet weight and dry weight of spinach plants. There is a relationship between soil NO3- and NH4+ levels with wet weight. Biourin concentration level of 2% is the best concentration to increase ammonium-N, wet weight and dry weight.

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

Peat soil has various characteristics due to differences in peat-forming materials, formation processes, and environmental conditions. In South Kalimantan, the environment of peat formation is more dominant in the form of transition peat and inland peat. This study aims to determine the characteristics of transition peat soil and inland peat, including soil pH, total acidity, carboxylic functional groups (-COOH) and OH-phenolic functional groups, in South Kalimantan at the level of hemic reshuffle. This study used a purposive sampling method with regard to the decompotion degree of peat, i.e., hemic (half baked). The soil used comes from transitional peat (Sub-district of North Ulin/LUU and West Ulin Platform/LUB) and inland peat (Banjang District, Hulu Sungai Utara/HSU) and Kandangan Subdistrict, Hulu Sungai Selatan/HSS). The results showed that soil acidity in transitional peat (LUU and LUB) was higher than inland peat (HSU and HSS) as indicated by the pH value of transitional peat soil with a range of 4.25 and a total acidity concentration of 234.16 cmol kg-1 for transitional peat, while the carboxylic groups (-COOH) concentration in transition peat (LUU and LUB) and inland peat (HSU and HSS) showed almost the same concentration of 94.91 cmol kg-1 in transitional peat (LUU and LUB) and 92.83 cmol kg-1 in inland peat (HSU and HSS). The concentration of OH-phenolic groups in transitional peat (LUU and LUB) is higher than inland peat (HSU and HSS), which is indicated by the transitional peat OH-phenolic (LUU and LUB) groups concentration of 139.25 cmol kg-1.

Abstract

Podsolic soil in South Kalimantan has a low fertility rate including pH, organic matter, cation exchange capacity (CEC), solubility P, and has a high solubility of aluminum (Al) and iron (Fe). It causes fixation P by Al and Fe in the form of Al-P and Fe-P, which makes P difficult to dissolve in the soil. Zeolite is an ameliorant that is capable of improving soil chemical properties based on its ability to carry out ion exchange, adsorption, absorb molecules, increase fertilizer efficiency, increase soil CEC, and the availability of Ca, K, and P ions, which can reduce aluminum content. The purpose of this study was to identify the pattern of relationships caused by application of activated natural zeolite on Podsolic soil against pH, CEC, available P, soluble Fe, and exchangeable Al. This study was a pot experiment weighing 0.5 kg of soil, carried out in a greenhouse and arranged using CRD a single factor . The incubation period was carried out for eight weeks with three replications. The results showed that there was a relationship between the zeolite dose activated against the available P (the linear regression equation Y = 0.6 + 0.032 X, R2 = 0.4969, and r = 0.7006*), while the doses of zeolite had no significant effect on pH, CEC, soluble Fe, and exchangeable Al.

Abstract

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.

Abstract

Swampland in Indonesia covers an area of ​​34.93 million ha spread over various islands such as Sumatra, Java, Kalimantan, Sulawesi, and Papua. One type of swamp land that is often used in agriculture is tidal lands. The problems faced in the development of tidal lands for agriculture include acidic soil pH, high levels of soluble Fe and Al. One of the efforts to overcome the problem of acidic soil pH, high levels of soluble Fe and Al-dd is liming. The finer grain level of lime may increase the effectiveness of liming. The purpose of this study was to quantify the effect of lime grain sizes on changes in pH, dissolved Fe, and exchangeable Al of tidal lands. This study employed a one-factor completely randomized design (CRD) consisting of 6 treatments (Control; CaCO3 more than 1.00 mm (> 18 mesh); CaCO3 lime, 0.5-100 mm (18 -35mesh); CaCO3 measuring 0.21-0.50 mm (35-70 mesh); CaCO3 measuring 0.21 mm (<70 mesh); CaCO3 lime measuring 0.15-1.00 mm (18 -100 mesh)). The results showed that the difference in the size of the CaCO3 lime granules had a significant effect on changes in pH, soluble Fe and exchangeable Al. The application of CaCO3 lime granules 0.21 mm (<70 mesh) result in increases in soil pH and suppress soluble Fe and exchangeable Al.
