The influence of topography on soil morphology, classification and characteristic is poorly understood in Ayer Hitam Forest Reserved, Malaysia. Topographic vegetation-soil interrelations are important because the existing plants are used to indicate environmental conditions and potential forest productivity. This study aims to identify the effect of toposequence on soil morphology, soil classification, soil characteristic and forest vegetation. Five plots surveyed on 100-150 cm soil profile depth to identify soil development, soil classification and nutrient status (i.e. organic matter, Al, pH, K, Na, Ca, Mg, CEC, Base Saturation). Besides, the distribution of forest vegetation serve as the basis to evaluate the trees’ basal area and diversity. Soil subgroups ranged from Fragic Hapludults in the ridge, Typic Hapludults and Plintic Hapludults on the middle slope, Typic Hapludults on the lower slope, and Typic Hapludults in footslope. Each soil subgroup has its characteristics at various elevations (Morphology and Physio-chemical). Vegetation on each plot was dominated by species of Euphorbiaceae, Myrtaceae, Dipterocarpaceae Malvaceae, Moraceae, Verbenaceae, Phylanthaceae, and Santalaceae.

This extraordinary peatland area can have various impacts, especially in Indonesia and even globally. In general, in soil classification, peat soil is known as Histosol. Based on the maturity level, there are safric, fabric, and hemic maturity levels. In general, peat soils have a relatively high level of acidity with a pH range of 3-4. Peatland management in the Central Kalimantan region has developed quite rapidly where many peatlands can be used as agricultural lands, such as in the Kalampangan area. Several types of land use analyzed in this study are dragon fruit monoculture, agroforestry with chili as the main crop, burnt forest, and natural peat forest. The analysis was carried out to determine the pH and available P content in the peat soil on each land use. The pH range in each land use is acidic with the highest actual pH range of 4 in the dragon fruit monoculture land use and the lowest in the natural forest landuse of 3,2. Meanwhile, the potential pH has a fairly similar value in the range of 2.1 to 2.5. The highest available P was obtained in chili agroforestry and the lowest was in the burnt forest. The highest available P was obtained in chili agroforestry and the lowest was in the burnt forest. The available pH and p values are strongly influenced by the management carried out by farmers, whereas in some areas the management is carried out quite intensively. An inventory of peat characteristics data is needed for current and future land development.

From the conservation standpoint, critical land is land that can no longer function to operate the water system, soil resources, and biodiversity that lives on the land. Critical land exhibits signs indications of environmental degradation as a result of numerous sorts of improper land resource utilization. The impact of critical land results in a decrease in the function of conservation, production function, and socio-economic life of the community. The Sumadi Farmer Group encountered hurdles downstream (marketing) and upstream (cultivation) due to limited land use and lack of human resources who understood plant conservation systems. Therefore, this community service aims to preserve critical land with biological conservation methods by improving soil quality, cultivating healthy plants, and controlling pests and diseases using vegetable pesticides. The activity began with the observation of agroforestry planting land, then socialization and presentation of material by the team of lecturers, followed by demonstrations on the land, and ended with an evaluation. Empowered with an understanding of cultivation techniques and restorative plant care, the Sumadi farmer group is passionate about developing an organic farming system to overcome land issues

Soil erosion is an environmental problem in the tropics that can cause the loss of topsoil. If it continues, it will result in a decrease in soil fertility and land productivity. So, it is necessary to quickly predict the erosion hazard level using the USLE method based on GIS. This research aims to analyze the distribution of erosion hazard levels in the Durensewu Sub-watershed, Gadjah Mungkur Reservoir Wonogiri, based on GIS. The research was conducted in the Durensewu Sub-watershed, Wonogiri, in January-April 2024. Data processed include rainfall (R), erodibility (K), slope (LS), and land cover and management (CP). The R-value in the Durensewu Subwatershed is 169.24-204.216. Soil groups of Ustropepts and Dystrudepts showed K values of 0.39 and 0.46, respectively. The topography of the Durensewu Subwatershed is gently sloping to very steep. Mixed gardens, settlements, and rice fields dominate land use. The erosion hazard level in the Durensewu Subwatershed is evenly distributed in the mild, moderate, and severe hazard classes.

Soil is the result of the transformation of minerals and organic matter from the surface to a certain depth. This process is influenced by various genetic and environmental factors, such as the properties of the parent material, climatic conditions, interactions with living organisms, topography, and changes that occur over a long period of time. This study aims to analyze the chemical properties of three different soil types—red soil, humus soil, and limestone soil—to understand their implications for soil management and agricultural productivity. The analysis was conducted at the Soil and Water Laboratory of UPT Agribusiness Development Malang from December 2023 to April 2024. The parameters tested included pH, P₂O₅ content, nitrogen, and K₂O. The results showed that limestone soil had the highest pH, phosphorus, and potassium values compared to red and humus soils, while all three types of soil had very low nitrogen content. This study highlights the importance of proper soil management to improve soil fertility and agricultural productivity.

Nutrients in sandy soil are limited due to low absorption capacity and are easily leached or evaporated. Biosilica and humic acid extracted from compost and husk ash can improve the soil structure and absorption capacity to optimize the availability and uptake of nutrients. Therefore, this research aims to examine the optimal application dose of biosilica and humic acid to improve the chemical properties of soil with a sandy texture. The experiment was structured based on a completely randomized design (CRD). Factor 1 consisted of biosilica doses of 0, 0.5, 1.0, and 1.5 tons ha-1, while factor 2 comprised humic acid doses of 0, 20, 40, and 60 kg ha-1. Data analysis was performed using ANOVA, followed by Tukey’s Honest Significant Difference (HSD) test, correlation, and determination analysis. The study results indicate that the combination of biosilica and humic acid contributes to the changes in nutrient availability. The impact of the treatment was observed 90 days after application on the parameters of soil pH, organic C, total N, and exchangeable K. The effects of the treatment were also evident in plant nutrient uptake, specifically in total N in the roots and total K in the stems. The optimal combination for improving soil nutrient availability and nutrient uptake in plant tissues was a biosilica dose of 1.0 tons ha-1 (S2) and humic acid at 40 kg ha-1 (H2).
