Most of the oil palm cultivation in Ultisols who have low fertility, nutrient deficiency and toxicity of micronutrient. The objectives of this research were to explore the interaction between sugarcane filter-cake (blotong) compost with synthetic fertilizer to improving chemical properties of Ultisols, growth of oil palm seedling, and the benefit of compost to save on the use of synthetic fertilizer. This research used a completely randomized factorial design, with two factors and three replication. The first factor was level of compost (0, 0.5, 0.75 kg polybag-1). The second factor was level of synthetic fertilizer (0, 0.25, 0.5, 0.75, 1 recommendation). The result showed that addition of compost till 0.75 kg/polybag in Ultisols could improve chemical properties of Ultisols like pH 6.11 units, organic C by 4.27%, total N by 0.47%, exchangeable-Ca by 7.78 cmolckg-1, exchangeable-Mg by 1.01 cmolckg-1, exchangeable-K by 0.36 cmolckg-1, CEC by 31.94 cmolc.kg-1 and decreased exchangeable-Al till not measurable. Combination of compost and synthetic fertilizer gave the interaction to increasing growth of oil palm seedling and nutrient uptake like tall of stem by 65.17 cm, biomass by 46.38 g, nutrient uptake of N by 62.47g crop-1. From this research recommended addition 0.5 kg polybag-1 compost and 0.5 R synthetic fertilizer to decrease the used of synthetic fertilizer till 50%, so that support soil health and environment.

Each land use has a different vegetation density and the litter input as a source of soil organic matter. Vegetation density index can be analyzed based on the NDVI equation using the GIS approach. This study aims to determine the effect of different land uses and NDVI on soil organic matter content and the mapping of soil organic matter content. This research was conducted from AprilÂ to August 2019 in Turen District, Malang Regency. The survey method used for collecting data in the field (36 observation points) based on differences in landform, relief, slope, land use (irrigated and rainfed rice fields), and vegetation density index classes (low, medium, high). Soil samples were taken at 0-20 cm depth and analyzed for soil organic matter content. Data interpolation using IDW was used for mapping soil organic matter. The results showed that there was a very significant effect between differences in land use and NDVI class on the content of soil organic matter (p <0.001). NDVI value gives an effect of 81.5% on soil organic matter content. The distribution of soil organic matter content is classified into 5 classes, which are very low, low, moderate, high and very high.

The distribution of very abundant AM in UB forest is very potential to be used as biological fertilizer. Biofertilizer production through the utilization of AM spores requires the multiplication of AM by using host plants namely maize (Zea mays L.), soybean (Glycine max (L) Merill) and tithonia (Tithonia diversifolia) and planting media consisting of soil added with cattle manure and rock phosphate. This study aimed to obtain the best host plants and growing media in producing the number of AM spores and AM colonies so that they can be used as AM biological fertilizer production. The study design used was a factorial randomized group design with host plants (H) as the first factor and planting media (M) as the second factor consisting of 18 treatments with 3 replications. The multiplication results showed that media with an M5 dose (150 kg ha-1 rock phosphate + 5 t ha-1 cattle manure) was high in producing AM spores amounting to 324,67 AM 100 g soil-1 in maize and 61.11% AM colonies in soybeans. Rock phosphate and cattle manure were sources of P in the growing media and AM which was multiplied to carry out its activities in producing phosphatase enzymes to produce P available for plants. Maize and soybeans had stable growth, good rooting, fast plant growth and low root lignin content which made it easy for AM to make colonies.

Training activities on the process of making organic fertilizer and LMO (local microorganisms) from various agencies have long been carried out in order to increase land productivity. According to the Regulation of the Minister of Agriculture number 70 / Permen / SR.140 / 10/2011, Â organic fertilizer products and soil ameliorant traded must include information on the label and there must be an effective test that applies an experimental design. The implementation of the Ministerial Regulation in the community partnership program is translated in the form of a) assistance to the business unit embryo to take care of a micro-small business permit certificate (SIUMK), b) assistance in making demonstration plots and observing records, c) laboratory testing facility assistance on the type and density of microbes from ameliorant products, as well as soil nutrient testing in various ameliorant application treatments, d) assistance in making packaging labels to search for stores where to buy packaging, and e) assistance in preparing reports on production patterns, production and marketing quantities, and preparing financial reports. Assistance activities can give birth to an ameliorant micro business unit in rural areas that has a business permit certificate and its products can meet the needs of the surrounding community. Besides, the assistance activities can improve the quality of production process skills and increase the quantity of ameliorant production that can provide provisions for micro-businesses to become independent. Because the potential for developing production and marketing of local ameliorant products is faced with the products of large companies, further technical and managerial support is needed. The form of continued support through the incubation of a small scale start-up business is expected to realize the micro-scale local ameliorant business unit to become independent and develop into a medium scale.

Coffee is a source of foreign exchange that plays an important role in the development of the plantation industry. However, many coffee-producing regions have experienced quite detrimental yields in recent years due to the rust of coffee leaves (Hemileia vastatrix), a parasitic fungus that reduces yields and that can ultimately kill coffee plants. The use of biochar enriched with Trichoderma can help to improve soil conditions and increase crop production because biochar can increase the availability of N and P. Trichoderma as a biocontrol agent that can help in solving the problem of coffee leaf rust. This study that was conducted at Gondorejo Village, Oro-oro Ombo sub-district, Batu District used a completely randomized design with seven treatments and four replications. The results showed that the application of media with a composition of 1% biochar enriched with Trichoderma supported the growth of Arabica coffee seedlings at the age of 3 months. It can be seen from the available N content, which showed an increase and the number of leaves which had the highest increase among other treatments. This indicated that the composition was sufficient to support good media for the growth of Arabica coffee seedlings.

Various efforts have been carried out by the Indonesian Government to increase rice production, especially the construction of new paddy fields and paddy intensification through increasing intensity or planting frequency in a year. Overcoming the problems of chemical and physical soil properties that have caused low soil productivity is an effort that can be made to increase rice production. This study was aimed to assess the quality of soil physical and chemical properties of the paddy fields in order to find out the cause of the low productivity of paddy soils. The study was conducted in 24 locations in Banten and West Java Provinces. In general, based on their soil quality indexes, the study found that the soil physical quality of paddy soil is good and better than soil chemical quality. There was no significantly different between soil physical quality of paddy soil in Banten and West Java Provinces. However, the soil chemical quality of paddy soils in West Java Province is significantly better than in Banten Province. There were no limiting factors for soil physical properties, while in some locations, some limiting factors of soil chemicals properties were found. Dominant limiting factors for plant growth were the low available P, organic matter and total organic N contents, low pH, and low exchangeable K, and high level of Fe.

The land use condition in Sumber Brantas Village, Batu City is 25.66% not compatible to the land capability class, while the land use condition based on the regional spatial plan there is an increase in land use by 32.05%. Land use conversion at Batu City in 2008 - 2015 reduced 748.06 ha of forest area in line with an increase in dryland area of 565.18 ha; and the increase of garden area by 329.84 ha. Transfer of land functions results in changes in land cover and causes a decrease in the potential of the actual forest function. A study related to the physical properties of the soil in Sumber Brantas Village is thus needed to obtain data on current soil conditions. This study was conducted to analyze the effect of differences in land cover and soil depth on aggregate stability and its correlation with other soil properties on the western slope of Mount Arjuna. Soil sampling was carried out on four types of land cover, i.e. horticulture, forest, shrub, and grassland at depths of 0-20 cm, 20-40 cm, and 40-60 cm with three replications for each treatment. The results showed that the type of land cover affected the soil aggregate stability, while the depth of the soil did not affect the soil aggregate stability. Organic matter influenced the value of aggregate stability with the R2 value of 0.87. Clay particles affected aggregate stability by 0.56. Aggregate stability affected soil porosity, soil macropores, and soil hydraulic conductivity with the R2 values of 0.76, 0.53, and 0.42, respectively.

This study aimed to determine the effect of rice straw compost and rice husk ash on some chemical properties of an Ultisol soil under sweet corn plant. This study was conducted at the Labuhan Batu Rantau Prapat University Campus Land and the PT. Socfindo Laboratory. The design used in this study was a randomized factorial design consisting of two factors with two replications. The first factor was the application of rice husk ash with four dose levels (g 5 kg-1 of soil), i.e. P0 (0), P1 (10), P2 (20), and P3 (30). The second factor was the application of rice straw compost with four dose levels (g 5 kg-1 of soil), i.e. J0 (0), J1 (25), and J2 (50), J3 (75). Results of this study indicated that the application of rice straw compost significantly increased soil organic-C and available P contents, as well as plant height, plant dry weight, N and P uptake by the plant. The treatments, however, did not significantly increase soil pH and total-N content. The application of rice husk ash significantly increased soil organic-C content and N uptake by the plant, but it did not significantly increase pH, available P content, and total N content of the soil.
