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.

The agriculture sector holds an essential role to produce foodstuff, including rice. Malang Regency accomplishes about 0,915% from the total of national rice consumption needed. Any natural factor can influence rice productivity such as the time of sun exposure, where sun exposure at around Malang Regency is equal to 7,5-10,7 hour day-1 based on data from 8 climatological stations. This study aimed at analyzing the influence of time exposure toward rice production potential in Malang Regency. The study consisted of four stages, namely: preparation, pre-survey, survey, and data analysis. Data analysis consisted of correlation and stepwise regression tests. The validation test was carried out to test the feasibility of the observed variables. In addition, a spatial analysis was carried out to determine the distribution of the duration of sun exposure and productivity of rice fields in Malang Regency using ArcGIS 10.3. The results showed that the time of exposure gives a low contribution impact on rice production potential with a correlation value of 0.023. This gives an explanation that there is another factor besides the time of sun exposure that could provide a bigger impact. Surface soil permeability in this research is the only other factor that could influence production potential significantly, with influence level as high as 14.7%. But, result from validation test showed that the p-value obtained is equal to 0.000 (p <0.05), indicating a significant difference between potential production based on the exposure with the results of the field survey, so that the exposure factor still could be used to predicted rice production result in Malang Regency.

The process of physical and chemical properties of the former gold mining soil which is caused by the transformation of different land conditions in natural rice fields, reclaimed rice fields, and mine fields. This study aims to determine the differences in the characteristics of the former gold mining soil in natural rice fields, reclaimed rice fields and mining fields in Sijunjung Regency. There were three sampling locations with three sample points each and the samples were analyzed physically and chemically. Results of this study showed that natural paddy soil has optimal conditions for the growth of rice plants followed by reclaimed lowland soil and the worst was in mining paddy soil based on soil physical and chemical properties. The difference in soil physical properties in the form of natural paddy soil texture was smoother compared to land conditions in reclaimed rice fields and mining rice fields. This was due to intensive inundation processes, which created a plough tread layer, low volume weight accompanied by a moderate total pore space. The difference in chemical properties was in the stable pH of natural paddy soil due to inundation and high organic carbon accompanied by rice reclamation and very low organic carbon in mining soils, which would affect the growth of rice plant.

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%.

PT Great Giant Pineapple (PT. GGP) is the largest pineapple production company in Indonesia. One of the nutrients that pineapple plants really need is potassium (K). K plays a key role in carbohydrate metabolism and transport of photosynthates from source to sink. Remote sensing technology has been developed to estimate nutrient status, one of which is using an Unmanned Aerial Vehicle (UAV). This study aims to estimate the K nutrient content in pineapple plants using vegetation indexes in the form of NDVI (Normalyzed Difference Vegetation Index), SAVI (Soil Adjusted Vegetation Index), and OSAVI (Optimized of Soil Adjusted Vegetation Index). The research was carried out by taking aerial photographs and samples of pineapple plants in the 5 months phase before forcing up to 2 months after forcing (F-5 to F + 2), laboratory analysis, statistical analysis, and making distribution maps. The results showed that the relationship between the vegetation index value and K plant was the strongest and most significant is in 1 month before forcing phase (F-1) with the same r value for the three indices vegetation (r=0.867). The results of the regression analysis between the NDVI, SAVI and OSAVI values with K plant were 75.17%, 75.18% and 75.17%, respectively. The calculation of the K estimate using three methods yields no different values. The validation results using paired t test (t count -0.63; t table 2.31; p-value 0.544) where the K content in the measured plants and the estimation results showed no significant difference with the measurement results.

UB forest area has various land uses, namely the use of agroforestry land based on coffee and seasonal crops. This will result in various physical properties of the soil in each use, therefore this study aims to determine the physical properties of the soil in different land uses and obtain optimal land use in the UB Forest area. The research was conducted from June to September 2020 in Malang district. The study was conducted on land use of pine forest areas, pine agroforestry + coffee, pine agroforestry + seasonal crops, mahogany agroforestry + coffee and mahogany agroforestry + seasonal crops. The parameters observed included analyzing bulk density, particle density, porosity, available water, water content pF 2.5 and 4.2, hydraulic conductivity, aggregate stability, texture and organic-C. The results showed that land use in the forest area of UB affected the physical soil, namely bulk density, particle density, porosity, hydraulic conductivity, and aggregate stability. Other physical properties, namely soil texture in the UB area. Dominant forest with dusty and clayey clay textures while available water had no significant effect and pine land use is optimal use based on physical properties of soil density, density, aggregate stability and hydraulic conductivity and is supported by the value of organic-C. Soil organic matter in coffee pine land use also has the highest value than other land ranges from 3.44 to 5.07%

Fire is a serious problem that must be faced in the management of forest or plantation areas. Land fires have caused huge losses of soil nutrient. Lampung is one of the provinces in Indonesia having a problem related to land fires. The purpose of this study was to analyze the impact of land fires on the soil base cations (K, Mg, Ca, Na) and cation exchange capacity (CEC) in three different planting zones (i.e. fertilization, harvesting path, and frond stack areas) within oil palm plantations between land with low fire intensity and land with high fire intensity. Observations were made using a survey method in three zones of oil palm plantations, including fertilization area, harvesting path, and frond stack area. Soil samples were collected by using a soil drill at two depths, namely 0-10 cm and 10-30 cm from the soil surface. The study showed that at depth 0-10 cm, land A (land with low fire intensity) had higher K, Na, and Ca contents, as well as higher CEC as compared to land B (land with high fire intensity). At depth 10-30 cm, field A had higher K and CEC content, and lower Mg content than land B. comparing among different zones of oil palm plantations also showed that soil exchangeable K and Mg were significantly different, especially at depths of 10-30 cm. This was due to differences in land management (i.e. fertilization and liming).
