Fulfilment of nutrients for plants can be maximized when fertilization, but the application of inorganic fertilizers can cause damage to the soil if the dosage is excessive. The utilization of phosphate solubilizing bacteria is an effort to increase the efficiency of phosphate fertilization that can extract phosphate from an insoluble form that becomes available. This study aimed to obtain a combination of inorganic fertilization doses (SP-36 and NPK) and the application of biological fertilizers that utilize phosphate solubilizing bacteria (PSB) to increase the population of phosphate solubilizing bacteria and P-available in the soil, as well as corn crop yields. This study used a randomized block design with nine treatments and three replications. The result showed that the application of PSB and inorganic phosphate fertilizer shows a significant effect on the population of PSB, P-available, plant height, stover dry weight, cob weight with husk and cob weight without husk, but didnâ€™t show a significant effect on 100 seeds weight and number of plant leaves. Based on the correlation analysis, the results show a positive correlation between soil chemical properties, P-available, and corn yield.

Coffee (Coffea sp.) is one of the leading commodities in Indonesia for it has a high economic value. In Bangelan Village, Malang Regency, there is a company that manages robusta coffee commodity. The land was converted into a coffee plantation from forest land. The conversion of forest land into a coffee plantation caused the decreasing number of total soil pores lower than the forest land. This will make it difficult for water to absorb into the soil. This research was conducted in Afdeling Besaran, PT. Perkebunan Nusantara XII Kebun Bangelan to elucidate the value of soil permeability and the nature of the relationship between them. The result of this research indicated that the permeability of the soil on each land map unit was in the category of fast permeability class and slightly fast permeability class. The highest soil permeability value was found on land map unit 2 at the 56 years average age of coffee robusta field, with each depth of 6.03 cm hour-1, 7.95 cm hour-1, and 7.82 cm hour-1. Soil permeability is influenced by soil porosity, sand and silt with a positive correlation way. In addition, aggregate stability, soil bulk density and clay also significantly affected the soil permeability with a negative correlation way. Permeability affected the production of robusta coffee plants with a positive correlation way of 16.09%.

Land continuously planted with corn will decrease land quality. Good land quality is needed to support soil function as a growing medium and keep a sustainable environment. This research was aimed to identify the soil quality index at land unit planted with corn in Mungka, ,Lima Puluh Kota Regency. This research used an explorative descriptive method through land survey and soil analyses in the laboratory. The samples were taken based on purposive random sampling at each land unit under the same slope (8%). There were three land units being sampled, and those were corn-corn, corn-eggplant, and corn-cassava cropping pattern. Corn-corn ropping pattern had the best soil quality index (0.89), followed by corn-cassava (0.86), and corn-eggplant (0.85) on the top 20 cm soil depth. On the 20-40 cm soil depth, the soil quality indices 0.82, 0.82, 0.83, for corn-eggplant, corn-corn, and corn-cassava cropping pattern, respectively. The quality index of the land under the corn cropping pattern was considered good either on the top 0-20 cm or 20-40 cm soil depth. This was due to the addition of organic matter from poultry manure to the land regularly. Based on this research, it is recommended to apply OM regularly to corn cropping pattern to keep a good soil quality index.

The maize crop is an important commodity other than rice in Indonesia. Maize production reached 30 million tons in 2018. Efforts that can be made to increase maize production on Ultisols in Indonesia is by the application of biochar rice husk and compost. Biochar that has a high affinity for nutrients does not experience decay in the soil for decades, while compost can improve soil chemical properties by increasing nutrient content. The purpose of this study was to analyze the effect of the application of a combination of rice husk biochar and compost on soil chemical properties, N uptake, and growth of maize on an Ultisol. This study was conducted with six treatments. The results showed that the application of a combination of rice husk biochar and compost had an effect on increasing the C-organic and N-total in soil, but it did not affect the C/N of the incubated soil. Application of a combination of 8 t rice husk biochar ha-1 and 30 compost ha-1 significantly improved plant height, dry weight, and N uptake of maize plants.

The plan to build a coal-fired steam power plant is expected to increase. One of the wastes generated from coal-fired steam power plants is coal fly ash. The accumulation of coal fly ash can cause environmental pollution such as soil and groundwater pollution in the storage location. Vermicompost can be used for managing coal fly ash by utilizing earthworms as decomposers. Earthworms can increase the availability of nutrients such as nitrogen, phosphorus, and potassium and reduce the solubility of lead contained in coal fly ash. The purpose of this study was to determine the effect of vermicompost using earthworm Eisenia fetida on the content of nitrogen, phosphorus, potassium, and lead in coal fly ash. Â The study consisted of five treatments, with a total weight of 3 kg coal fly ash each. The results showed that mixing cow dung in vermicomposting of coal fly ash significantly increased N, P, K and decreased Â Pb in vermicompost.

Inceptisol has a special characteristic, which is low in organic matter. Other chemical problems possessed by Inceptisol include acidic pH, high clay content, and washable surface layers. The compost of goat manure can improve soil chemical properties. The purpose of this study was to determine the effect of the application of goat manure compost at various doses on the carbon and phosphorus content of Inceptisol soil in Bangelan, Malang, East Java. The treatments tested were K1D1 (0-20 cm depth, without compost dose), K1D2 (0-20 cm depth, with compost dose 0.5 g 500 g-1 soil), K1D3 (0-20 depth, with compost dose 1 g 500 g-1 soil), K2D1 (20-40 cm depth, without compost dose), K2D2 (20-40 cm depth, with compost dose 0.5 g 500 g-1 soil), K2D3 (20-40cm depth, with compost dose 1 g 500 g-1 soil), K3D1 (40-60 cm depth, without compost dose), K3D2 (40-60 cm depth, with compost dose 0.5 g 500 g-1 soil), K3D3 (40-60 cm depth, with compost dose 1 g 500 g-1 of soil). The nine treatments were arranged in a completely randomized factorial design with three replications. The results showed that at a depth of 0-20 cm, 20-40 cm, and 40-60 cm with an additional dose of 1 g 500 g-1 of soil was the best dose given into the soil because it had a significant effect on increasing pH, C-organic, available P and total P in the soil.

Hydrocarbons are compounds produced as a result of the activities of the petroleum industry, which can pollute the soil and waters. Due to the amount of waste, biochar from agricultural waste could potentially be used as a soil amendment agent for hydrocarbon contamination. The high lignocellulose in oil palm shells and empty bunches makes them potential raw materials for biochar. The purpose of this study was to explore the effect of biochar application on petroleum-contaminated soil to reduce Total Petroleum Hydrocarbon (TPH) levels. In this study, the dosage of biochar was added to the soil contaminated with petroleum with a variation of 3%, 5%, and 7% (w/w) and control without the addition of biochar. The parameters analyzed were TPH levels by gravimetric method every week for four weeks. The results showed that the addition of biochar had an effect on the degradation of TPH. The greater the dose of biochar used, the higher the percentage of TPH degradation. The highest decrease in TPH levels occurred at the addition of biochar dose by 7%, where the empty shell was 60.65%, and empty bunches was 54.1% which was greater than without the addition of biochar by 32.79%.
