Maize is one of the world's food crops besides wheat and rice, which is strategic to increase production. Ultisol is a type of soil spread across Indonesia with a land area distribution of 45,794,000 ha and has the potential to be used to increase corn crop production. This study aimed to elucidate the effect of the combination of coal fly ash (CFA) and chicken manure (CM) on P uptake and growth of maize grown on an Ultisol. The CFA doses applied were 0, 10 and 20 t ha-1 of coal fly ash, while the CM doses applied were 0, 10 and 20 t ha-1 of chicken manure. Observations included soil pH, total P, available P and P uptake by maize. The results of the study showed an increase in soil pH, but still showed a value below 5,5. The addition of coal fly ash and chicken manure as much as 20 t ha-1 provided the highest P availability and showed the highest P nutrient uptake value by corn crops. The application of coal fly ash and chicken manure can increase the availability of P better than without the addition of chicken manure. But, the application of coal fly ash up to 20 t ha-1 also inhibited the growth of maize by marking a decrease in the results of measuring the dry weight and height of maize plants.
玉米是世界上除小麦和水稻以外的粮食作物之一，对提高产量具有战略意义。Ultisol是一种遍布印度尼西亚的土壤，其土地面积分布为4579.4万公顷，具有用于增加玉米作物产量的潜力。本试验旨在研究粉煤灰(CFA)和鸡粪(CM)配施对Ultisol上玉米磷吸收和生长的影响。粉煤灰用量为0、10和20 t ha-1，粉煤灰用量为0、10和20 t ha-1，鸡粪用量为0、10和20 t ha-1。观察土壤pH、全磷、速效磷和玉米对磷的吸收。研究结果表明，土壤pH值有所增加，但仍低于5,5。粉煤灰和鸡粪添加量为20 t hm -1时，玉米磷素速效最高，磷素养分吸收值最高。施用粉煤灰和鸡粪比不施用鸡粪能更好地提高磷的有效利用率。但是，施用20 t hm -1的粉煤灰也抑制了玉米的生长，使玉米植株干重和干高的测量结果下降。

The yield of irrigated paddy rice in Sri Agung Village has decreased. In the last four years, the increase in the addition of input units (fertilizers) has not been followed by an increase in economic yields. This study aims to analyze the effect of organic fertilizers on soil fertility, such as pH, total N, organic C, available P and available K. The research was conducted in the rice fields of Sri Agung Village. Batang Asam area, West Tanjung Jabung Regency - Jambi. The research was conducted from April to September 2020. The study used a randomized block design with six treatments and five replications. The treatments tried were: Recommended Fertilizer (R), five types of organic fertilizer with a dose of 10 t ha-1 each, namely, Petroganik+R ( P1), Compost Solid Decanter + R (P2), Chicken Manure + R (P3 ), Cow Manure +R (P4) and Industrial Waste Compost + R (P5). The results showed that organic fertilizers significantly increased available K content of paddy soil but they did not significantly increase soil pH, total N, organic C and available P. The highest yield of dry milled grain (7.52 t ha-1) was obtained at +R (P1) Petroganic treatment.

Land use in an area is influenced by population growth and activities. Changes in land use continuously will cause environmental changes that often trigger an increase in natural disasters. In this study, the assessment was carried out using the calculation of the Normalized Difference Vegetation Index (NDVI), Normalized Difference Wetness Index (NDWI) and Soil Adjusted Vegetation Index (SAVI). The data used came from Landsat OLI 8 imagery data from 2020 to 2023. The results of this study showed that in the range of 2020 to 2023 the changes in the three calculations of the vegetation index were not significant. From the data obtained, the classification for calculations in the rainy and dry seasons was the same, the NDVI vegetation index obtained high vegetation, the SAVI vegetation index obtained forested vegetation, and the NDWI vegetation index obtained high wetness. Overall the assessment of the vegetation index obtained good results, and it can be concluded that not all areas in Semarang City are at risk of flooding, even during the rainy season.

Application of balanced fertilizers and the use of decomposers on land can improve soil health and nutrient availability for plants. Giving recommended doses of fertilization through the use of multispectral camera images lead to more efficient fertilization. This study aims to analyze the impact of the application of decomposers on the implementation of a multispectral camera image-based fertilizer recommendation system on soil physical properties, growth, and crop yield. This research was carried out from November 2021 to April 2022 at the experimental field in Sukamandijaya Village, Ciasem District, Subang Regency, West Java. This study was carried out with 2 treatments, namely land without the decomposers (P1) and with the decomposers treatment (P2) on rice fields of the Mekongga variety. The decomposer used was Petro Gladiator with dose 5 liters/ha (480 ml/plot or 56 ml/m²). Data analysis was carried out by unpaired T test at 5% level to determine the effect of decomposer application on soil physical properties as well as growth and crop yield. The results showed that the application of decomposers to fertilizer recommendation systems based on multispectral camera images can improve soil conditions including improvements in soil bulk density, soil particle density, total pore space, soil moisture content pF 1, 2, and 4.2, available pore water, then soil pH, available-P soil contents, potential-K soil content, as well as rice plant height.

Nitrogen is a primary macro nutrient needed by plants and has an important role in plant growth. Regosols, Latosols, and Grumusols are soils that have the potential as a medium for plant growth, with different characteristics and levels of productivity and are constrained by soil nitrogen. Application of nitrogen-rich vermicompost as an alternative to overcome the problem of the three soils. The research aimed to determine the available nitrogen content and nitrogen absorption of pakcoy by adding vermicompost on Regosols, Latosols, and Grumusols. The research used a split-plot design with the main plot in the form of soil types (T1 = Regosols, T2 = Latosols, and T3 = Grumusols) and a subplot in the form of a dose of vermicompost fertilizer (K0 = 0 t ha-1, K1 = 10 t ha-1, K2 = 20 t ha-1, and K3 = 30 t ha-1) so there are 12 treatments and repeated three times. The results showed that the application of vermicompost to Regosols, Latosols, and Grumusols increased total N, available N, organic carbon, cation exchange capacity, plant height, fresh weight, dry weight, plant N, and plant N uptake. The dose of vermicompost 20 t ha-1 was the optimum dose for the parameter of N availability.

One of the medicinal plants that are rarely cultivated in Indonesia is okra. This plant has a business opportunity that can bring benefits to farmers. This research aimed to elucidate the effect of a compost mixture of coffee grounds and milled eggshell on nitrogen and calcium contents in a regosol soil and growth and yield of okra plants. Fertilizer treatments tested were: P0 (control), P1 (100% inorganic), P2 (25% compost + 75% inorganic), P3 (50% compost + 50% inorganic ), P4 (75% compost + 25% inorganic), and P5 (100% compost). The results showed that the application of a compost mixture of coffee grounds and eggshell with a dose of 100% compost had a significant effect on increasing soil pH, total N, and Ca compared to control, namely 30,77%, 147,52%, and 643,54%, but did not significantly affect the organic C of the soil. The application of coffee grounds and milled eggshell compost with a dose of 100% significantly affected plant height at 8 WAP and plant stem diameter at 6 WAP. The application of coffee grounds and milled eggshell compost with a dose of 100% significantly increased fresh fruit weight and dry weight of okra plants, respectively 18.27% and 33.33% compared to the control.

Soil develops from the rocks of the Waturanda Formation in Lebakwangi Village is from sedimentary tertiary volcanic activity. The purpose of this study was to identify the soil morphology and soil classification in the Waturanda Formation with forest and dry land use according to the Soil Taxonomy 2014, World Reference Base 2015, and National Soil Classification 2016. The soil profile from the topsoil to subsoil under the forest land use was dominated by clay texture (49.04%-56.46%), with particle density 1.20-1.24 g cm-3, bulk density 1.64-1.82 g cm-3, pH (H2O) 4.05-4.68, pH (KCl) 3.42-3.55, organic C 1.47-2.29%, CEC 13.05-19.60 cmol(+) kg-1, and saturation base 24.35%-73.70%. Similarly, the soil profile under the dryland use was dominated by clay texture (37.06%-62.60%), with particle density 1.10-1.20 g cm-3, bulk density 1.58-1.75 g cm-3, pH (H2O) 4.32-4.54, pH (KCl) 3.49-3.65, organic C 0.96-1.66%, CEC 19.95-25.81 cmol(+) kg-1, and saturation base 58.35%-95.43%. Both soil profiles have an udic humidity regime and isohyperthermic soil temperature regime. Soil classification according to Soil Taxonomy, WRB, and NSC for forest land is Humic Eutrudepts, Clayic Haplic Luvisols, and Eutrict Cambisols, while for dryland use is Pachic Hapludolls, Clayic Haplic Luvisols, and Haplic Molisols.

The agricultural sector is still the leading sector of the economy in Wonosobo Regency. Its superior commodities include paddy rice, tea, tobacco, coffee, and vegetable plants. In the practice of agricultural activities, it is inseparable from the use of inorganic fertilizers and persistent chemical pesticides that cause heavy metal contamination in agricultural land. Industrial waste around agricultural land that enters the water body also contributes to the accumulation of heavy metals in the soil of the water for irrigation. This study aimed to determine the distribution of heavy metal content of Pb, Cd, Ni, Co, Cr, and As on the agricultural land of Wonosobo Regency. The study was conducted on the agricultural land of Wonosobo Regency. As many as 312 soil samples were taken from a layer of sports (depth of 0-20 cm) of agricultural land in ten sub-districts of Wonosobo Regency. Soil sample analysis included heavy metals Pb, Cd, Ni, Co, Cr, As, organic Carbon, CEC, and soil texture. The analysis was carried out in an integrated laboratory, the Agricultural Environment Research Center. The results showed the concentration of heavy metals detected in Wonosobo Regency agricultural land respectively Pb > Co > Ni > Cr > As > Cd. These heavy metals in the soil are still in normal concentrations and are safe for agricultural land.
农业部门仍然是沃诺索博摄政经济的主导部门。其优势商品包括水稻、茶叶、烟草、咖啡和蔬菜。在农业活动的实践中，造成农用地重金属污染的无机肥料和持久性化学农药的使用是分不开的。农业用地周围的工业废弃物进入水体也会导致灌溉用水土壤中重金属的积累。本研究旨在确定沃诺索博县农用地重金属Pb、Cd、Ni、Co、Cr、As的分布。该研究是在沃诺索博摄政的农业用地上进行的。在沃诺索博县10个街道的一层农田(深度0-20厘米)中采集了多达312个土壤样本。土壤样品分析包括重金属Pb、Cd、Ni、Co、Cr、As、有机碳、CEC和土壤质地。这项分析是在农业环境研究中心的综合实验室进行的。结果表明:沃诺索博县农用地重金属检测浓度依次为Pb > Co > Ni > Cr > As > Cd，均处于正常水平，对农用地安全。
