This study aims to determine the effect of the groundwater level on the evolution of CO2 in peat soils if the groundwater table is lowered from a depth of 40 cm (PP No. 57 of 2016 concerning protection and management of peat ecosystems) to a depth of 60 cm. This study was conducted in a greenhouse and Laboratory of Physics, Chemistry and Biology Department of Soil, Agriculture Faculty, ULM. This study was began in October 2021 and continued until February 2022. The research method used was a factorial Completely Randomized Design (CRD) with four replications. The factors tested were the water table of the peat at a depth of 0 cm just above the soil surface (T1), 20 cm below the soil surface (T2), 40 cm below the soil surface (T3), and 60 cm below the soil surface (T4). The results of this study showed that the CO2 evolution of peat soil during incubation for 1, 2, 3, 7, 14, 21, and 28 days at a depth of 20 cm was not significantly different from a depth of 40 cm and 60 cm, but significantly different when the groundwater level was right at the surface soil. The CO2 evolution of peat soils at groundwater levels at the soil surface was lower than water levels 20, 40, and 60 cm below the ground.

Peatlands are developed for the cultivation of plantation crops such as oil palm. However, recently the focus on the development of peatlands for this activity has been so great, especially in relation to the emission of carbon dioxide CO2 into the atmosphere during land clearing, burning of biomass and maintenance of oil palm. The potential for peatland to be used as agricultural land must pay attention to environmental aspects such as the level of CO2 emissions to these changes. This study aims to determine the effect of wood charcoal and empty oil palm fruit bunches on CO2 emissions and their relationship to C-Mic and C/N ratios on peatlands overgrown with oil palm. This study used a randomized block design. The factors studied were the distribution of wood charcoal and empty palm fruit bunches at four levels, namely: control; wood charcoal 0.75 kg; empty palm fruit bunches 0.75 kg and empty palm fruit bunches 0.375 kg + wood charcoal 0.375 kg. Each treatment was repeated 3 times, so that 12 experimental units were obtained. The results showed that on day 0 and day 45 the addition of wood charcoal and empty palm oil bunches had no effect on CO2 emissions, but on day 15 the results showed that the treatment had an effect on CO2. emissions and soil microorganisms (C-mic). Unstable C/N ratios and value of CO2 emission increased or decreased when sampling on different days.

Peatlands are developed for agricultural cultivation, such as oil palm. The agricultural sector contributes 13.5% of the total greenhouse gas (GHG) emissions. Emissions from this sector are generally in the form of N2O 46%, CH4 45%, and CO2 9%. Recently, the focus on the development of peatlands for this activity has been so great, especially in relation to emissions of nitrous oxide (N2O). The potential for peatland to be used as agricultural land must pay attention to environmental aspects such as the level of N2O emissions. This study aims to determine the effect of wood activated to empty palm oil fruit bunches on N2O emissions from peatlands oil palm. This study used an allocation block design. The factors studied were the distribution of wood charcoal and empty palm oil bunches at 6 levels, namely: wood charcoal + 0 kg of empty palm fruit bunches; wood charcoal 0.75 kg + 0.75 kg of empty palm fruit bunches, and 0.375 empty palm fruit bunches+0.375 kg of wood charcoal; empty palm fruit bunch charcoal 1.5 kg+wood charcoal 1.5 kg. N2O gas was analyzed using the closed chamber method and the soil was analyzed for soil pH and field water capacity. The treatment was repeated 3 times, resulting in 18 experimental units. The results showed that on day 0, the application of wood charcoal and empty palm oil bunches did not affect N2O emissions, but on the 15 and 45 days. The results showed that the treatment affected N2O emissions.

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.

In the practice of oil palm plantation management, land clearing and cultivation using heavy equipment will change soil conditions from anaerobic to aerobic. This condition will cause sulfide compounds contained in the soil, or commonly referred to as pyrite (FeS2) to undergo an oxidation process that can cause the formation of sulfuric acid compounds (H2SO4) which when dissociated will release H+ ions in the soil solution, thus increasing soil acidity. In addition, improved drainage will also lead to a high likelihood of plant nutrients being leached from the soil. On the other hand, the HCV areas will be left unmanaged by maintaining the original vegetation adjacent to the oil palm plantations. So there are two different land management systems between oil palm land and HCV areas which in theory will have different land characteristics, one of which can be seen from differences in soil chemical characteristics. The purpose of this study was to determine the differences in the characteristics of several soil chemical properties including pH, C-organic, Al-dd and P-available in oil palm land and HCV areas. This research is a field research using survey method. Sampling in the field was carried out by purposive sampling at PT Kharisma Inti Usaha, Tapin Regency, South Kalimantan Province. Soil samples used in this study were soil samples at a depth of 0-30 cm and 30-60 cm on oil palm land and HCV areas where each land was taken as many as 10 sampling points, so that the total sample points amounted to 40 sampling points. The results showed that the characteristics of soil acidity (pH), carbon (C-organic), aluminum (Al-dd) and phosphorus (P-available) on oil palm land were lower than HCV areas in PT Kharisma Inti Usaha Tapin Regency.

Supporting the increase in agricultural production today cannot be separated from the use of herbicides in land preparation activities. Most of the herbicides applied to plants will eventually fall to the ground, then undergo changes and in a certain time will be absorbed by the clay fraction and organic matter in the soil, which is generally known as herbicide residue. Toxic herbicide residues in the soil can kill soil microbes, which are not actually the target (non-target microorganisms) so that they interfere with the activity of soil microorganisms which in turn can affect the nutrient cycle in the soil.This research was conducted with the aim of knowing the effect of giving herbicides with various types of active ingredients in paddy fields on the viability of N-fixing bacteria and their relationship to soil chemical properties.The research and analysis was carried out from November 2021 to January 2022. The method used in this study was the Completely Randomized Design (CRD) environmental design method with a single factor treatment design, namely the type of herbicide active ingredient. Based on the results of research that has been carried out, it is known that the herbicide Glyphosate can increase the population of atmospheric N2-fixing bacteria in the soil, while the herbicide Paraquat and Methyl Metsulfuron can suppress the population growth of atmospheric N2-fixing bacteria

Podzolic soil is characterized by acidic condition, low base saturation, and low CEC and nutrient contents. The use of chemical fertilizers in agriculture may damages soil and environment and may eventually affect the health of humans. The objective of this study was to quantify the effect of cow urine on changes in pH, available N (NH4+ and NO3-), and available P of Podsolic soil. This study employed the completely randomized design two factors, in which first factor was the amounts of applied cow biourine: control (without biourine, 5.2, 10.4 and 15.6 mL of biourine), while the second factor was the incubation period: 2 and 4 weeks. Following the completion of each incubation period, soil pH, contents of ammonium, nitrate, and available phosphrous were determined for each treatment. Results of this study showed that the application of cow biourine with an incubation time of two and four weeks significantly influenced the ammonium and nitrate contents in soil. The higher amount of biourine applied, the higher ammonium and nitrate contents in the soil. The research results also showed that the application of cow biourine had an influence on available P content, but had no effect on changes in soil pH.
