Appropriate fertilization recommendations are needed to maximize the production of oil palm plants on land that has been used for a long time. This study aimed to determine the status of soil fertility during the oil palm replanting period in Kemang Manis Village, Muara Papalik Sub-district, West Tanjung Jabung Regency, and determine fertilization recommendations according to the needs of oil palm plants based on soil fertility. This study used a survey method; soil samples taken were disturbed soil samples, and sampling was carried out at two depths, namely 0-30 cm and 30-60 cm. Determination of sampling points using stratified random sampling method based on homogeneous land units that were processed based on soil type and slope in the research location. The collected soil samples were analyzed for H, CEC, BS, organic C, P2O5, K2O, and total N. The results showed low fertility status during the oil palm replanting period in the research location. Observations of the soil profile also showed that the O horizon was thin. Fertilization recommendations that must be made to improve soil fertility include adding dolomite fertilizer to increase soil pH value and increasing the availability of N, P, and K elements in the form of Urea, SP36, and KCl. To increase the content of organic materials in the soil, applying oil palm empty fruit bunches can also improve the soil's physical, chemical, and biological properties.

Optimizing land use plans is carried out for land capabilities that are useful for conserving land resources so that they can reduce the problem of land degradation. This study aimed to assess the level of land capacity and determine the function of both protected and cultivated areas in Development Area Units (SWP). The method used in the research is quantitative descriptive, consisting of data collection and processing stages. Data collection was carried out through literature studies from several related agencies. Meanwhile, spatial data analysis was carried out using Geographic Information System (GIS) software. The results of the research showed that the analysis of land capacity, especially for determining the function of areas for settlement, reached 3,687.35 ha and the buffer area was around 11,755.27 ha. This indicates that only a small portion of suitable areas can be developed for urban development. This is due to the physical limiting factors of the land where the characteristics of the Ambon City area are dominated by hilly areas.

Red-yellow podzolic soils are generally acidic and have poor chemical properties, so tolerant plants such as oil palm plants are needed. This research was to determine the effect of differences in the age of oil palms on the chemical properties of the Sei Daun plantation soil. The research was conducted in December 2022 using the method of purposive sampling according to plant age. Samples were taken from 5 lands with oil palm ages 8 years, 14 years, 16 years, and 25 years, as well as land without plants, 5 points were determined from each land, and each point was separated into 3 depths, namely 0-20 cm, 20-50 cm, and 50-70 cm, the 5 points were composited according to depth, producing 3 samples per field. The results of the analysis of soil chemical properties show that increasing the age of oil palm causes soil pH, thereby reducing available P, total N, exchangeable K, and CEC of soil, but increasing soil organic C, also increasing Fe-NH4OAC, Mn-NH4OAC, exchangeable Al but still in low value. Increasing the age of oil palms can lower the soil pH, thereby reducing the availability of nutrients. Fertilizer doses can be adjusted according to the age of the plant because the older it is, the more nutrients the plant absorbs.

The difference in the productivity level of paddy is caused by nutrient availability and land management. This study aims to determine the chemical properties of soil, especially elements of N, P, and K, in soils that have different levels of rice productivity. The methods used in this study are survey methods and laboratory analysis. Purposive sampling was conducted based on the productivity of medium and high-status rice fields. Based on the level of productivity of rice fields, there are 18 sample points, which are composite into 7 samples and analyzed in the laboratory. The results showed that several chemical properties in areas with high productivity levels had an average availability of total N nutrient status of 0.17% (low), potential P 56.5 mg 100 g-1 (high), potential K 17 mg 100 g-1 (low), organic C by 2.75% (medium), cation exchange capacity (CEC) 11.52 cmol(+)kg-1 (low) while in areas with medium productivity had an average total N nutrient of 0.23% (medium), potential P 38.33 mg 100 g-1 (medium), potential K 72 mg 100 g-1 (very high), organic C 3.23% (high), CEC 33.06 cmol(+)kg-1 (high) and has a soil pH of 6.1 (slightly acid) respectively. High-productivity areas have low to medium soil fertility, while medium-productivity areas have medium to high soil fertility. Rice field management factors are suspected to cause differences in rice productivity levels.

Part of the dry land in Madura developed from parent material, namely sand sediments which have a low organic matter content. This study aimed to determine differences in the effectiveness of corn seed coating materials from bentonite, biochar, lignite, and biochar compost on the growth and yield of maize (Zea mays L.) under drought stress conditions. This study was conducted at the Integrated Laboratory and screen house of the Faculty of Agriculture, University of Jember, using a completely randomized design. The treatments tested in this study comprised two factors. The first factor was the treatment of coating materials, namely C0 = without coating (control), C1 = bentonite coating, C2 = biochar coating, C3 = lignite coal coating, and C4 = biochar compost coating. The second factor is the level of drought stress, namely K0 = control (100% KL moisture), K1 = Light stress (80% KL moisture), K2 = moderate stress (60% KL moisture), and K3 = severe stress (40% KL moisture). The results showed that the combination of seed coating agent treatment and drought stress had a significant effect on the parameters of plant height, number of leaves, leaf area, age of male and female flowers, cob length, cob diameter without husks, biomass dry weight, and production potential per hectare. The coal coating material and light drought stress 80% KL (C3K1) was the best combination of seed coating and drought stress treatment.

The conversion of rice fields in Seyegan is suspected to occur due to low soil fertility. This study was conducted to analyze the extent and distribution of conversion of rice fields associated with soil fertility status. This study used a survey method, purposive determination of sample points on rice fields representing the converted rice fields, and soil samples were taken compositely. Data analysis used spatial analysis, graphs, and laboratory tests. The parameters tested were cation exchange capacity (CEC), Base Saturation, potential P2O5, potential K2O, and organic C. Determination of soil fertility status was based on The Technical Guidelines For Soil Fertility Evaluation of Soil Research Center. The results showed that the area of rice fields in Seyegan District in 2015-2022 decreased by 55.26 ha (3.76%), with an average annual decrease of 7.89 ha. The soil fertility status in rice fields converted into settlements was very low to medium, rice fields into dryland and poultry farming were medium, and rice fields into shrubs and factories were low. The limiting factors of soil fertility were CEC and organic C.

Drought stress and acid soil pH are a form of abiotic stress on acid-dry land. Actinomycetes are a group of transitional microbes that have benefits as bioprotectants, biostimulators, and biofertilizers. This study aimed to determine the optimum growth environment for Actinomycetes at various incubation temperatures (25, 30, 35, and 40 ℃) and media pH (5, 6, 7, 8, and 9) and prove its effectiveness on mustard plants when given drought stress, and increase in acid soil pH. The research was conducted in the LOB greenhouse of PT Great Giant Pineapple using two factors, namely Actinomycetes (F22, F26, F34, F39, and F47) and irrigation (watered and not watered). Observations included Actinomycetes population (CFU mL-1), plant response (percentage of stress, death, survival, recovery), plant growth (plant length, number of leaves, root length), plant production (fresh weight), soil pH, and soil organic matter. Results of this study showed that Actinomycetes F22 gave the highest total population (107 CFU mL-1), and the P4K1, P4K2, and P2K2 treatment combination gave the best results on the observed parameters.

Low nutrient availability and high soil bulk density are caused by the loss of fertile soil particles due to the kinetic energy of rain. Land management that does not apply conservation principles such as soil covering is one of the factors causing this to happen. This research was conducted to determine the impact of using plastic mulch as one of conservation actions. This research was conducted at the experimental field University of Siliwangi, Mugarsari. Soil samples were taken from mulched and without mulch lands as treatments. Soil samples were collected at 0-10 and 10-30 cm soil depths. Soil samples were taken to analyze the chemical properties of the soils (i.e., pH H2O, organic C, total N, available P, exchangeable K, Ca, Mg, Na) and physical properties (i.e., soil bulk density, porosity, water content, and texture). The results showed that the use of mulch had a significant effect (p<0.05) on pH H2O, organic C, total N, available P, exchangeable K, exchangeable Ca, bulk density, and water content. The results of the correlation showed that increasing organic C in mulched land had an effect on decreasing BD (r = -0.739). In addition, the organic C increased soil porosity (r = 0.612). Meanwhile, soil depth had no effect (p>0.05) on soil chemical and physical properties.

Oil palm fronds are waste products of oil palm plantations that are not utilized, yet oil palm fronds can be converted to biochar to improve soil fertility. This study aimed to analyze the chemical properties of the biochar generated from oil palm fronds. A pot experiment was conducted in Negeri Lama Seberang Village, Labuhanbatu District, Rantauprapat. The biochar formulation consisted of two formulations, i.e., A = pure biochar (biochar in its original form) and B = granule biochar (biochar + tapioca flour). Each biochar form was repeated five times to obtain ten samples. The results of biochar laboratory analysis were continued with statistical tests based on the dependent t-test at the 5% level using Microsoft Excel. The results showed that biochar granules had chemical characteristics such as organic C of 32.78%, N of 2.39%, P of 0.18, K of 0.75%, and pH of 8.07. These values showed that granule biochar has better chemical characteristics than pure biochar.
油棕叶是油棕种植园的废弃物，没有得到利用，但油棕叶可以转化为生物炭，提高土壤肥力。本研究旨在分析由油棕叶生成的生物炭的化学特性。研究人员在拉布汉巴图地区的 Negeri Lama Seberang 村进行了盆栽实验。生物炭配方包括两种，即 A = 纯生物炭（生物炭的原始形态）和 B = 颗粒生物炭（生物炭 + 木薯粉）。每种生物炭形式重复 5 次，共获得 10 个样本。对生物炭实验室分析结果继续进行统计检验，检验方法是使用 Microsoft Excel 进行 5%水平的从属 t 检验。结果显示，生物炭颗粒的化学特性为：有机碳 32.78%、氮 2.39%、磷 0.18%、钾 0.75%、pH 值 8.07。这些数值表明，颗粒生物炭的化学特性优于纯生物炭。
