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

One of the prospective places for agricultural usage in acid sulfate rice fields, which are typically spread out in lowland areas along coastlines that occasionally undergo flooding. If handled effectively in accordance with the issues found in the land, this site can be developed as a productive agricultural region. Agricultural development on acid sulfate soils frequently encounters a number of issues, including (pH) acidic soil, high iron content, a lack of phosphate availability, and the presence of pyrite (FeS2). In this study, the relationship between P availability, Fe solubility, the Fe-P fraction, pH, Eh, and pyrite depth in acid sulfate paddy fields will be examined. Purposive sampling was used in field research utilizing the survey method in the acid sulphate rice fields of Barito Kuala Regency. This research was based on the distribution map of Fe solubility in Barito Kuala Regency. The results of this study indicate that there are three variables that have a significant effect on P availability: soluble Fe amd Fe-P fraction with the power regression form and a very strong relationship; and soil pH with a linear regression form and a strong relationship. Pyrite depth and soil Eh had no significant relationship with P availability in acid-sulfate lowland rice fields.

An understanding of land suitability or management such as on peat and mineral soils in oil palm plantation areas is also very necessary as a basis for determining technical cultural actions to be taken in order to ensure the sustainability of the productivity of a land. This research was conducted with the aim of knowing the chemical properties of peat soils in Margasari Village, Candi Laras Utara District, Tapin Regency and mineral soils in Martadah Baru Village, Tambangulang District, Tanah Laut Regency under the auspices of oil palm plantations. The method used in this study was a quantitative descriptive method. The sampling point was determined by purposive sampling by showing the existing canopy in the field. Soil sampling in the field at a depth of 0-30 cm for each type of soil. This research plan is intended to describe soil pH, organic-C, total-N, and available-P. In general peat soils had quite high C-organic content values compared to mineral soils. Changes in organic C affected the properties of the soil. The organic C content in all research locations was categorized as very low to medium, the soil pH is acidic, the total N content was moderate and the available P content was categorized as very low.

Peat soil is a soil that has been decomposed by organic matter. Man-made peatlands have been converted into agricultural land. In addition to being turned into agricultural land, some peatlands are also not used, causing the land to turn into shrubs and causing land to burn because it is not managed by the owner. Peatlands therefore consist of various types of land use. Peat soils in different types of land use have different characteristics. The purpose of the study was to determine the differences in some of the chemical properties of peatlands that have been used for shrubs, open land, and agriculture. To see the differences in soil chemical properties on various land uses, descriptive analysis, and standard deviation are used by presenting bar charts. The soil pH content on agricultural land is higher. The C-organic content in shrubs is higher than in agricultural land. Ash content on agricultural land is higher. Dissolved organic carbon on agricultural land tends to be lower.

This research aims to determine differences in soil acidity, C-microorganisms and the growth of spring onion (Allium fistulosum L.) on peatlands based on the difference in distance from waterways. The study will be conducted from February 2022 to May 2022. The implementation of the research is located in the Greenhouse and in the Laboratory of Physical Chemistry and Biology, Department of Soil Science, Faculty of Agriculture, Lambung Mangkurat University, Banjarbaru. This research method is quantitative research with a survey approach using exploratory descriptive methods. The data analysis used was by paired T-Test analysis to find out the differences in parameters observed over a period of five days. The result of this study was that there was a difference in soil acidity and growth of spring onion plants, while C-microorganisms was not.
