Various crop commodities are grown in Ngawonggo Village with various land uses, including rice fields, dry fields and agroforestry which are dominated by intensive agriculture. As a result, this agricultural pattern can potentially cause land degradation. One of the technological inputs in improving sustainable crop production systems is the application of mycorrhizal biofertilizers. This study aims to determine the level of population, mycorrhizal colonies and types of spores and the factors that influence them in rice fields with rice (Oryza sativa), dry fields with sengon (Paraserianthes falcataria), and agroforestry with coffee (Coffea sp.) and Durian ( Durio zibethinus). The study used a randomized block design with sampling on three land uses, with 5. The results obtained only one type of mycorrhizal spore of Glomus sp. on all land uses. The highest number of spores was in agroforestry land use, as much as 102 g-1 soil, and the lowest was in rice fields, as much as 10 g-1 soil. Mycorrhizal colonies on plant roots were the highest in agroforestry land use, it was found that 42.77% of coffee roots were colonized by mycorrhizae, followed by durian with a colonization proportion of 42.29%, rice fields with commodities had the lowest colonization proportion of 16.21%.

Leaves of Reutealis trisperma (locally known as kemiri Sunan) are potential sources of organic matter and improve soil fertility, especially by increasing soil nutrient availability. This study aimed to analyze the impact of the application of compost using kemiri Sunan leaves as raw material on soil fertility, such as pH, total N and soil organic C. This study used a completely randomized design with six treatments and four replications. The treatments were without compost (control), compost 4 t ha-1, compost 8 t ha-1, compost 12 t ha-1, compost 16 t ha-1 and compost 20 t ha-1. This study used a PVC pipe with a diameter of 14 cm and a height of 60 cm for the composting process and using polybags for the soil incubation process. The leaves were mixed with EM4, molasses, and water in a ratio of 1:1:50; after mixing, all the ingredients were put into a tube, and observations were made. The soil was then mixed with compost according to the treatment dose of compost 0; 4; 8; 12; 16; 20 t ha-1, then added water until it reached field capacity and then put into a polybag and incubated for 30 days. Observations were made at 0, 15, and 30 days after incubation. The results of this study showed that the application of waste compost of kemiri Sunan leaves had a significantly increased soil pH, total N, and organic C. The best application of kemiri Sunan leaf compost was found at a dose of 20 t ha-1 .

Vertisols have a comparatively low total N content till they are needed, so they need extra external fertilizers within the sort of fertilizers. The coating is one methodology for making fertilizer within the sort of slow-release. The aim of this study was to analyze the impact of zeolite, sago, a mixture of chitosan, and potato flour as a coating for urea fertilizer on the provision of available N and also the chemical properties of Vertisols Pasuruan. This study used a completely randomized design (CRD) with 6 treatments consisted of K (no coating), P1 (zeolite 10%), P2 (sago 2%), P3 (chitosan 3% : potato starch 8%), P4 (zeolite 20%), P5 (sago 4%) and P6 (chitosan 6% : potato starch 6%) with 3 replicates. The results showed that the application of several coating materials on urea had a significant effect on the rate of nitrogen release in the form of ammonium and nitrate from week 1 to week 4. P6 (chitosan 6%: potato starch 6%) treatment showed the lowest results in the release rate of ammonium by 12.517 ppm, which was categorized as high and nitrate by 3.005 ppm, which was categorized as low. The urea coating treatment resulted in lower ammonium and nitrate than the uncoated treatment. The application of several coating materials on urea had a significant effect on the pH value of the soil and cation exchange capacity (CEC). The P6 treatment showed the highest result on the soil pH of 5.363 and CEC values of 41.878 me 100 g-1.

Alfisols have low fertility, so fertilization is carried out to increase soil fertility and support the growth of maize plants. The continuous use of inorganic fertilizers in high quantities can cause land degradation, so it is necessary to reduce the amount by adding other fertilizers, such as organic fertilizers, as well as the relatively high price of inorganic fertilizers. This research was aimed to examine the potential of organic fertilizers in replacing inorganic fertilizers. The experimental design was a completely randomized block design with nine combination treatments of organic and inorganic fertilizers with three replications. The results showed fertilizer treatment ½ NPK + 1 PO affected and increased levels of organic C, CEC, base saturation, total N, and available P in Alfisols and maize yield. However, it did not significantly affect pH, base saturation and available S in Alfisols. The chemical properties of the soil had increased values of 48%, 9.01%, 61.3%, and 134.5%, respectively. The treatment of ½ NPK + 1 PO increased maize productivity by 47.76% compared to the control with the productivity of 12.7 t ha-1, which the results were not significantly different from standard NPK. Thus, the application of 10 t ha-1 of organic fertilizer has the potential to replace ½ doses of inorganic fertilizer.

Soil thickness has a significant influence on many of earth surface processes, and it can be mapped using various methods. Digital soil mapping can be used to estimate the spatial distribution of soil thickness and can estimate the uncertainty of the soil prediction map. Digital soil mapping using regression methods such as Multiple Linear Regression (MLR) and Regression Krigging (RK) was used to estimate soil thickness of the slope of Bener Reservoir. Bener Dam is a national strategic project which is built for irrigation to improve farming quantity. The aim of this research was to determine the spatial variation of the soil thickness at the slope of Bener Reservoir. The accuracy of MLR and RK were compared to select the best soil thickness prediction. There were 212 and 53 soil thickness samples from fieldwork which were used for data training and testing, respectively. There were 5 environmental variables such as elevation, distance from river, slope, plan curvature, and topographic wetness index. R programming language with gstat, krige, and stats Packages was employed for MLR and RK prediction. The result showed that KR is more accurate than MLR.

Onion has become one of the popular horticulture commodities in Indonesia due to the crop having several benefits. Consequently, the demand for onions in Indonesia increases annually. In contrast, the supply of onion fluctuates because of unstable onion production. One of the factors that affect unstable onion production is soil fertility degradation. Therefore, the study aimed to analyze the effect of different doses of inorganic fertilizer compounds on the chemical properties of soil, plant growth and production. The field research was conducted in the experimental land of the Faculty of Agriculture, Brawijaya University, located in Jatimulyo Village, Lowokwaru District, Malang City. This study could not detect a significant difference in fertilization doses on onion plant growth but could increase the yield and tiller numbers. The highest values of tillers number, tuber fresh weight and tuber dry weight were observed for the treatment of 50% basal fertilizer + 150% compound inorganic fertilizer and the lowest production of biomass, tillers number, wet weight, and tuber dry weight was on treatment control.

Land use in Bogor Regency has diverse vegetation and different soil characteristics. Soil characteristics have an influence on land management. Improper land management has led to a decrease in microbial populations, biodiversity and a decline in soil quality and fertility. Soil fertility is produced by the interaction of the physical, chemical, and biological properties of the soil. This study aims to determine the correlation of soil biological and chemical properties in several different types of land use in Bogor Regency. Soil sampling was carried out using the purposive random sampling method with five replicates. Soil samples were taken at a depth of 0-20 cm by ±1 kg. The research site includes eight land uses namely bamboo gardens, sengon gardens, lamtorogung gardens, and dragon fruit orchards. The results of the analysis showed that the dragon fruit field had an acid pH with very high organic C and total N levels with the highest fungal population of 2.27 x 105 CFU g-1. Meanwhile, bamboo fields with an acid pH also have a medium organic C content and low total N with the lowest total fungi population of 0.37 x 105 CFU g-1. Azotobacter populations and respiration values had the highest correlation with the total P content of the soil. The correlation value of the total population of fungi was the highest, with a total N levels of 0.427.
