Water is a natural resource that is very important because its existence is needed for living things, including plants that need water for their growth and development. The availability of water in the soil has different amounts because it is influenced by various soil properties in the land. Land that has a sloping ground surface, the movement of water that enters the ground does not only move vertically as in land that has a flat surface but also laterally is parallel to the sloping land surface and moves down the slope. The first land has a slope percentage of 6%, the second has a slope of 13%, the third has a slope of 23%, and the fourth has a slope of 37%. The study consisted of 4 treatments for different levels of a land slope, and nine replication points were carried out. The results of this study indicated that the difference in the level of slope in each land had an effect on the water content in the soil at a depth of 40-60 cm; the higher the percentage of the slope of the land reduced the availability of groundwater. Specific gravity, porosity, and soil meso pore had a significant effect on the soil water content with a positive correlation direction, meaning that the higher the density, porosity, and soil meso pores, the more water available in the soil. Macro pores and soil micro pores had a significant effect on soil water content with a negative correlation, meaning that the higher the macro pores and soil micro pores will reduce the available water in the soil.

Regosol has low fertility, especially carbon (C), nitrogen (N), phosphorus (P), potassium (K) and other macro elements, but it can be potential for agriculture cultivation. Addition of straw compost and tithonia granule (Kojeto granule) with clay binder can improve chemical soil fertility. This study aimed to determine the composition of the Kojeto granule with a clay binder and to define the interaction between type of Kojeto granule and dosage of compost granule in the chemical characteristics of Regosol. This research was conducted in a wirehouse and soil laboratory, Andalas University. The experiment used a completely randomized factorial design, with two factors and three replications. The first factor was the ratio between compost composition and clay binder 9:1 and 8:2. The second factor was 4 levels of granule compost doses (0; 7,5; 15; 22,5 t ha-1). The results showed that the best composition ratio between Kojeto and clay binder on chemical properties was 9:1. The type of Kojeto 8:2 and dosage (22 t ha-1) had an interaction on Ca-dd (3.75 me 100 g-1). The single effect on the type compost granule at type 9:1 was parameter C-org (2.23%), and single effect on increasing the dosage of granule compost at a dose of 15 t ha-1 was C-org (2.30%), N-tot (0.27%), P-available (14,30 ppm), pH (5,80), and K-dd (0.62 me 100 g-1). The optimal recommended dose is 15 t ha-1.

Rice husk biochar and compost application are expected to improve soil chemical properties such as pH, organic carbon, and available P in Ultisol, which in turn improves crop growth and P uptake by plants. The purpose of this research was to analyze the effect of the combination of rice husk biochar and compost on the soil chemical properties (pH, organic carbon, and available P), maize growth, and P uptake by maize in an Ultisol. The research used a Randomized Block Design with six treatments (P0: control; P1: 4 t biochar ha-1; P2: 30 t compost ha-1; P3: 4 t biochar ha-1 and 30 t compost ha-1; P4: 8 t biochar ha-1 and 30 t compost ha-1; P5: 4 t biochar ha-1 and 60 t compost ha-1) and four replications. The result showed that the combination of 8 t rice husk biochar ha-1 and 30 t compost ha-1 showed a significant effect on increasing pH, organic carbon, and available P in an Ultisol, increasing the height of maize crops at 4 and 6 WAP (weeks after planting). However, it had no effect on the number of leaves and showed an effect on the increase in P uptake of maize crop.

Differences in tree age and cropping systems may influence the microbial diversity, including fungal species and population. The purpose of this study was to determine the diversity, of species and population of arbuscular mycorrhiza spores and the relationship between the number of arbuscular mycorrhiza spores and the soil chemical properties in different pine age group and coffee as an intercropping system at sloped areas. The study was conducted from April to July 2017. The study used a survey method with 5 age groups (KU) and three replications. The study was divided into 3 stages: 1). collection of soil and root samples, as well as measuring plot characteristics (i.e. basal area, canopy cover, standing litter mass); 2). Measurement of Mycorrhizal in the laboratory (spore extraction, spore identification, root colony percentage analysis); 3). Soil Chemical Analysis (pH, total P, available P). All data was tabulated, and tested using ANOVA with Randomized Block Design. If there is a significantly different, a further LSD test is performed with a level of 5%. Correlation and regression tests were performed to determine the relationship between parameters. The results showed that there were significant differences in the parameters of canopy density, number of genus spores of Acaulospora 100 g-1 soil, Soil pH, and total P in the soil. However, the study was unable to detect significant differences in, other parameters, such as root infection, number population of Glomus and Gigaspore, available P, etc.. The correlation test showed that the increase in the age group of the coffee intercropping system did not correlate with the number of arbuscular mycorrhizae in each plot observed. The number of Arbuscular Mycorrhizal Spores in each age group of intercropping pine did not correlate with the soil's chemical properties (pH, P-Total, P-Available).

Peat land has an important role, function, and benefit for human life, biodiversity, and global climate. The peat swamp forest in Central Kalimantan was devastated to a very large extent, which addresses the restoration of peat swamp forests, has changed the characteristics of peat which contain physical, chemical, and biological characteristics. Peat recovery efforts carried out at the KHDTK Tumbang Nusa consist of natural succession and revegetation. The study aimed to analyze the chemical properties of peat soils in different types of post-fire forest protection and to assess the spatial variability of peat chemical properties in Forest Areas for Special Purposes (KHDTK) Tumbang Nusa, Desa Tumbang Nusa, Jabiren Raya District, Pulang Pisau Regency. The research plot consisted of forest restoration efforts, namely secondary forest, revegetation, and natural regeneration. Variable measured consisted of pH, total organic C, CEC, N, P, K, exchangeable K, Na, Ca, Mg, as well as ash content and water content. The results showed that secondary forest treatment was the best peat swamp forest restoration technique. Spatial variability sub-plots and sample points did not significantly affect the differences in chemical properties of the peat, but the differences in chemical properties of peat is the peat swamp forest was determined by restoration technique.

The research that was conducted from April to December 2020 in the Supiturung Micro-Watershed, located on the western slope of Mount Kelud, Kediri was aimed to study the morphological characteristics and soil classification using a topo-sequence approach. Four pedons were observed across the physiographic positions (upper, middle and lower slopes) on dry-land farming land use. The method used in this research included 8 stages, namely the preparation stage, pre-survey, map making, field observations, laboratory analysis, soil classification, data processing, and reporting. On the field, cross-sectional profiles were carried out on four selected pedons by testing the soil profile measuring 1 x 1 meter with a depth of 150-200 cm, followed by soil horizon, soil thickness, texture, structure, consistency, effective depth, type and number of pores, as well as other characteristics. Soil samples were collected from the genetic horizon of the pedons for being analyzed using standard procedures, then taken to the laboratory for soil physical and chemical analysis. Soil morphology with physicochemical properties was then classified based on the Keys Taxonomy of Soil to the Sub Group level. The results showed that each pedon has a different Sub Group. This condition can be caused by many factors, such as differences in epipedon thickness, base saturation values, organic C levels, and other morphological conditions at the time of direct observation. Four pedons have lithologic discontinuities, recognition of these types of lithologic changes is important because pedogenesis and pedogenic interpretations are greatly influenced by changes in the parent material.

Landslide is a form of natural phenomenon that often occurs in mountainous and hilly regions with steep up to very steep slopes. Landslide is the movement of slope-forming materials in the form of rocks, debris, soil or materials down the slope. This study aimed to identify the distribution of landslide-prone areas in Ajibarang, Banyumas Regency. The research was conducted by survey method. The model used to determine landslide-prone areas was the Stories Index Model approach. Analysis of geophysical factors was based on SPOT-5 image data and the Indonesia Topographical Map (RBI Map). Identification of land geophysical factors for susceptibility level was determined according to geological map, slope map, soil type map and land use map. The results showed that the level of landslide susceptibility in the study area was divided into 4 classes, namely very low (3.733,41 ha), low (3.303,73 ha), moderate (123,49 ha) and high (150,37 ha).

Soil degradation to support the growth and development of plants and produce goods and services has become a global concern. To support government programs and efforts to improve land, the role and cooperation of researchers with local governments should be increased to multiply, and information related to the potential of soil degradation can be used as supporting data for development planning in an area. The potential and status of soil degradation in the region of East Kutai Regency, are still relatively low. But it has a high potential for damage because land use more increasing for various purposes. Soils in East Kalimantan is dominated by old soil, such as Podsolic or Ultisols, easily damaged if utilized without regard to principles of conservation. Especially for soil in Rantau Pulung there is a parameter with exceeded status of standard quality, i.e. permeability; then in Batu Ampar found four parameters, namely permeability, the composition of soil fraction, bulk density and soil pH, next to Long Masangat founded two parameters, namely bulk density and permeability. The more of limiting factors, then in the land use should also apply and demand high conservation treatment to maintain the land or soil quality.

Coffee plants are one of the plantation crops that are widely cultivated by smallholders in Sumbermanjing Wetan District. The problem that is often experienced by coffee farmers is the decline in coffee production due to climate. The adverse effect of climate change can be overcome through mitigation by implementing shade plants. The saturated hydraulic conductivity of the soil is defined as the movement of water in a porous medium in a saturated state. By measuring hydraulic conductivity, it can determine the ability of the soil to conduct water and see the movement of water in the soil. The highest value of saturated hydraulic conductivity at a depth of 0-20 cm was found in coffee plants with sengon shade at 31.02 cm hour-1. The highest value of saturated hydraulic conductivity at a depth of 20-40 cm was found in coffee plants with the shade of Dadap plants, which was 56.67 cm hour-1, included in the fast category. Differences in shade and soil depth in coffee fields affect the value of the saturated hydraulic conductivity. There is a relationship between several physical properties of the soil and the saturated hydraulic conductivity of the soil. The physical properties of the soil affect the saturated hydraulic conductivity of the soil.
