Abstract

Land management in, Amandit sub-sub watershed must comply with the principles of soil and water conservation to avoid erosion and sedimentation. The aim of this research was to assess water quality and soil characteristics that predict erosion in the upstream, middle and downstream areas. The purposive sampling method was used by taking soil and water samples in the upstream, middle and downstream parts. In the upstream section soil samples were taken with a slope of 15-25%, in the middle section with a slope of 8-15% and in the downstream section with a slope of 0-8%. Soil samples were taken at each of six points representing the upstream, middle, and downstream parts of the area. Water sampling was carried out in the soil sampling area by paying attention to the slope of the land. The results showed that the water quality (pH, DHL, SAR, and TSS) in the area was in accordance with the quality of water for irrigation. Soil erodibility values in the upper and middle areas did not show significant differences. In the upstream part, soil erodibility had very low criteria and the middle part had low criteria but were different from the downstream area (medium criteria).

Abstract

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.

Abstract

One of the challenges of acid sulfate soil is the high Fe content in the soil, thus effective processing is needed to address its toxicity. The purpose of this study was to determine the changes in soil pH, Fe solubility, and organic-C from liquid fertilizer in acid sulfate soil in Danda Jaya Village, as well as to determine the relationship between soluble Fe and soil pH, organic-C and soil pH, and soluble-Fe. This research was structured using a descriptive method by comparing the application of liquid fertilizer with a control. The study was conducted in the Chemistry, Physics, and Biology Laboratory of the Soil Department, Faculty of Agriculture, Lambung Mangkurat University. The results of the study showed that the application of liquid fertilizer was able to increase pH and organic-C and decrease Fe solubility. Additionally, there was a correlation between soluble-Fe and pH with a coefficient of -0,95, a correlation between organic-C and pH with a coefficient of 0,91, and a correlation between organic-C and soluble-Fe with a coefficient of -0.89. Furthermore, the equation for the relationships was soil pH = -0.002 soluble-Fe + 5.958, Soil pH = 0.30 organic-C + 4,43, and soluble Fe = -154.92 organic-C + 830.15.

Abstract

Paddy fields for all of Indonesia are 8.1 million ha, about 43% are in Java and about 57% are outside Java. Paddy fields are part of the wetlands. Paddy fields control the global climate through the gases they produce and have a greenhouse effect. One of the greenhouse gases is methane, therefore the purpose of this study was to determine the effect of rice field waste management on methane emissions and the population of methanogenic microorganisms. The research method used is one-factor Completely Randomized Design (RAL). The factor tested was the method of managing rice waste before planting rice with five treatments namely: A = Rice field waste was slashed and then lifted into the mound after a few days of being returned to the field; B = Rice field waste is carried out management slashed, rolled up, reversed, and stretched; C = Rice field waste is slashed, planted with traces and then slashed again after the trace is transferred to land outside the research plot; D = Rice field waste sprayed with herbicide 2 times; E = Ricefield waste sprayed with herbicide 1 time and then soil in the tractor. Each treatment was repeated four times so 20 units of the experimental. CH4 gas retrieval used the hood method while the microorganism population used the MPN (most probable Number) method. The results showed that the rice field waste management method had an effect on methane emissions and populations of methanogen microorganisms in the planting and vegetative phases, while the generative phase had no effect.

Abstract

Podzolic soil is marginal land for agriculture because low N availability and low lettuce plant growth production can be overcome by appropriate fertilization. This study aimed to determine the effect of fresh Azola application on nitrogen availability, number of leaves, and fresh weight of lettuce plants on Podzolic soil. This research employed a single factor of completely randomized design (CRD), in which the treatments were: A0= control, A1= fresh Azola 4 t ha-1, A2= fresh Azola 8 t ha-1, A3= fresh Azola 12 t ha-1, A4= fresh Azola 16 t ha-1. Soil chemical characteristics: soil pH, contents of total N, NH4+, NO3-, organic C, and cation exchangeable capacity were determined on the 21st after incubation, while plant height and plant fresh weight were observed at harvest. The research results showed that increasing the amount of fresh Azola applied to the soil resulted in a tendency to increase soil pH, total N-content, N-NH4+, N-NO3-, number of plant leaves, and fresh weight of lettuce plants.

Abstract

Critical land is land that is no longer productive from an agricultural perspective, because management and use do not consider land management requirements and soil conservation principles. This research aims to assess the level of criticality of land based on the level of erosion that occurs at various coal mining land locations in several districts in South Kalimantan. This research is non-experimental research using exploratory descriptive methods. The data collected is secondary data obtained through official publications from the Environmental Service and related agencies from several environmental documents of coal mining companies that have received approval from the authorized Agency. The secondary data used is the data needed to calculate the amount of erosion which is used as a basis for evaluating land criticality. These data include: soil texture, permeability, bulk density, rainfall, slope and slope length, management factors, land cover vegetation factors and soil organic C. Erosion estimation uses the Universal Soil Loss Equation (USLE) method. The results of erosion calculations using USLE show that in open mine land in Banjar Regency it is 233.9 tons ha-1 year-1, while in Tanah Laut Regency is 173.1 tons ha-1 year-1 and in Kotabaru Regency is 275.1 tons ha-1 year-1. The level of criticality of land in the mining area is at a critical and very critical level compared to natural land and cultivated land due to differences in erosion values ​​and also the thickness of the soil solum studied.

Abstract

Tidal land has low P availability due to soil acidity (pH) and the high fixation of Al and Fe into complex compounds. This study aims to determine the effect of dolomitic lime, calcite, and tohor (quicklime) on the soil pH, exchangeable Al, soluble Fe, available P and cation exchange capacity (CEC) in tidal land. The research method used was a one-factor Completely Randomized Design (CRD). The factors tested were the type of lime with three different doses (10 treatments) including control, 1.6, 2.7, and 3.9 t dolomite ha-1, 3.0, 5.0, and 7.0 t calcite ha-1, and 1.9, 3.2, and 4.5 t quicklime ha-1. The results showed that the application of various types of lime had a significant effect on pH, exchangeable Al, soluble Fe, available P, and CEC. The quicklime application at 4.5 t ha-1 increased the soil pH, solubility of P, CEC significantly and decreased exchangeable Al and available Fe compared to dolomite and calcite.

Abstract

Soil properties are the inherent characteristics of soil bodies in different locations that are influenced by factors such as mineral composition, structure, texture, and organic content. Soil has characteristics that affect the growth of the plants that are cultivated. This study aims to determine the physical and chemical characteristics of Ultisol soil at a depth of 0-50 cm on rubber plantation land in Cempaka District, Banjarbaru City. This research was conducted in the laboratory of ULM Soil Department. The land used was in Gunung Kupang, Cempaka Village, Cempaka District, Banjarbaru City, South Kalimantan Province. The research method used in this study is an exploratory descriptive method whose implementation is carried out directly at the research site and continued with soil sampling as material for analysis in the laboratory. Soil sampling was purposefully determined in 10 minipits in rubber plantations with two sides of observation at five depths, namely 0-10 cm, 10-20 cm, 20-30 cm, 30-40 cm, and 40-50 cm. Thus, all observations amounted to 100 samples. The data analysis used is presented in graphical form and analyzed descriptively. The results of this study show that increasing soil depth causes changes in soil physical characteristics. Physical characteristics of soil texture values affect the value of bulk density, particle density,and soil moisture content. The phenomenon of changes in physical characteristics ultimately affects the chemical characteristics of C-organic, soil pH, N-total, P-total and K-total values.

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
