The aim of this research was to study the decline of organic functional group through the process of burning in peat. In addition, this study was also to examine the relationship between water content in peat and organic functional group after combustion (burning). Peat drying was conducted in an oven at a temperature of 75°C with the interval of 0, 1, 2, 3, 4, 5 and 6 hours. Each time interval had three replicates within two sets of experiments so that the total number of samples were 42 (experimental units). Variables measured were moisture content, total acidity, COOH groups, and OH-phenolate. The relationship between the water content with total acidity, COOH groups and OH-phenolate were determined by the equation y = bx + a. The results showed that the relationship between the water content with organic functional group was linear. While the relationship between peat water content with organic functional group after burning was irregular, although water levels through the process of burning have been greatly reduced.

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.

Peat swamp land in Indonesia is quite extensive, which is 10.8% of Indonesia's land area, the area of peatland in Indonesia is estimated at around 14.95 million hectares, the largest on the islands of Sumatra, Kalimantan and Papua and a small part in Sulawesi. The dry process is not good can be associated with bulk density. Irreversible dryness can occur in peat with low lindak density, while peat with high lindak density is relatively easy to reabsorb water. Peat soils store much higher carbon than mineral soils. Every gr of dry peat stores about 180-600 mg of carbon, while every gr of mineral soil contains only 5-80 mg of carbon. This research method uses a descriptive exploratory method whose variable approach is carried out through land surveys and is supported by the results of soil analysis in the laboratory. The results showed the value of water content and water absorption of peat soil in the protected forest of Banjarbaru peat soil based on different times and showed a decrease in the level and absorption of peat soil.

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.

Podzolic soil is characterized by acidic condition, low base saturation, and low CEC and nutrient contents. The use of inorganic/chemical fertilizers in agricultural activities is very worrying because it can cause damages to the soil and the environment and will even affect the health of humans. This can be anticipated by using organic fertilizers , including organic waste or animal waste. Cow urine is an alternative that can be used as liquid organic fertilizer because it contains high levels of nutrients in the form of nitrogen, phosphorus and potassium. The objective of this study was to determine the effect of cow urine on changes in pH values, available N (NH4+ and NO3-), and P-available of Podsolic soil. The soils were given cow biourine with 4 levels (namely: without biourine, 5.2 ml, 10.4 ml and 15.6 ml) and were incubated with 2 different periods (2 weeks and 4 weeks). After two and four weeks incubation, the soil pH, Ammonium, Nitrate, and P-Available were analyzed. Then the effect of treatments on soil pH, Ammonium, Nitrate, and P-Available was tested acording to factorial randomized complate design and DMRT. The results showed that the administration of bovine biourin could increase Ammonium, Nitrate, Nitrogen and P-Available.
