Abstract

Entisols are soils that are widely used in Indonesia, both for irrigated and rainfed rice fields, for vegetable cultivation, and others. Vermicompost also contains many of the nutrients available to plants and increases soil porosity, soil aeration, and humidity, and controls soil erosion so that it can help in buffering toxins for plants and promoting plant growth. Corn is a cereal crop that is the second most important food crop in Indonesia besides rice. The volume of corn imports is higher than exports, this is due to the high demand for corn but domestic corn production has not been able to fulfill it. The experimental design used was a Randomized Completely Block Design (RCBD), seven levels of vermicompost doses, namely 0; 2.5; 5.0; 7.5; 10; 12.5; and 15 tons ha-1) each repeated 4 times. This study aims to determine the dose of vermicompost fertilizer that can improve the properties of Entisols and yields of maize (Zea mays L.). The application of vermicompost fertilizer with seven dose levels had a significant effect on N nutrient levels in coastal Entisols. Doses of vermicompost were able to increase dry stover weight, cob weight with husk, and cob weight without husk of corn plants.

Abstract

Ultisols has prominent weaknesses and problems such as high acidity levels, low water absorption capacity, and low nutrient content such as N, P, K, Ca, and Mg, so it has the potential to inhibit plant growth. One way to overcome Ultisols soil problems is to use vermicompost fertilizer. Corn is one of the plants that is suitable for cultivation using vermicompost fertilizer. The research aims to obtain the best dose of vermicompost for corn growth and yield in degraded Ultisol soil. The research was conducted in Sri Kuncoro Village, Pondok Kelapa District, Central Bengkulu Regency, Bengkulu Province. The design used a single-factor Complete Randomized Block Design (RCBD) consisting of 5 treatment levels and five replications to obtain 25 experimental plots of 0, 7.5, 15, 22.5, and 30 tons ha-1. Data were analyzed using Analysis of Variance (ANOVA) at a 5% level and continued with the Least Significant Difference (LSD) test at a 5% level. The research results showed that the dose of vermicompost significantly affected the variables of plant height, number of leaves, number of leaves, and plant dry weight. The best vermicompost treatment dose was 22.5 tons ha-1 with plant height 254.85 cm, number of leaves 13.26, stem diameter 24.90 mm, leaf area 811.49 cm2 , cob length with husk 24, 93 cm, cob length without husk 17.26 cm, cob weight with husk 218.19 g, cob weight without husk 194.26 g, dry seed weight of plant samples 153.33 g and Dry seed weight per ha 9.1 tons.

Abstract

[ANNUAL FLOOD PHENOMENON AND FERTILITY STATUS OF RICE SOIL IN THE COASTAL AREA OF BENGKULU]. The rice fields in Rawa Makmur Village were agricultural land that was affected by annual floods. Soil fertility status is important for increasing the productivity of paddy. The research aimed to get the fertility status of soil affected by annual flood disasters, evaluating and mapping the distribution of soil fertility status at the research location. The methods used in this research include survey and soil testing methods at the Soil Science Laboratory, Faculty of Agriculture, Bengkulu University. Further evaluation of soil fertility status is in accordance with technical instructions from the Soil Research Center, Bogor (1995). This research was conducted in June – August 2023. The soil CEC value from each sampling point was classified as high with values ranging from 28.15 me/100 g - 39.83 me/100 g. The base saturation value in the study was classified as very low to moderate with values ranging from 11.49% - 40.08%. Soil organic C at the research location from each sampling point was classified as moderate to very high with values ranging from 2.42% - 5.97%. The soil phosphorus content at the research locations observed was classified as very low to low with values ranging from 2.69 mg/100 g – 12.11 mg/100 g. The soil potassium content at each sample point at the research location observed was classified as very low with values ranging from 0.14 mg/100 g – 1.43 mg/100 g. The research results show that the flood phenomenon has a significant impact on soil fertility. The soil fertility status at the research location is classified as low. Soil fertility parameters which are limiting factors in the status of soil fertility in Rawa Makmur Village are phosphorus, potassium and pH. So it is necessary to add P and K fertilizer to improve the soil fertility status.

Abstract

Sandy soils are characterized by their loose texture, low water-holding capacity, and generally low organic matter content, all of which significantly influence soil chemical properties. Soil chemistry serves as a critical indicator of soil fertility and directly affects plant productivity. This study aimed to analyze both the morphological characteristics and the changes in chemical properties of sandy soils cultivated with chili plants in erosion-prone areas. A descriptive quantitative method was employed, with soil samples collected before planting and after harvest. Sampling followed the standards outlined in the USDA Field Book for Describing and Sampling Soils. The chemical parameters analyzed included soil pH (H₂O), soil organic carbon, total nitrogen, available phosphorus (P₂O₅), and potassium (K₂O). The results indicated measurable changes in all tested soil chemical properties. The sandy soils in the study area were clas sified as Inceptisols, distinguished by horizon differentiation observed in the subsoil layer. Post-harvest analysis revealed increases in organic carbon, total nitrogen, and available phosphorus levels, while pH and potassium concentrations decreased. These findings suggest that agricultural activity in erosion-prone sandy soils can influence nutrient dynamics, potentially supporting sustainable vegetative conservation practices. Appropriate land management strategies—such as the incorporation of organic matter, implementation of terracing, and adoption of agroforestry systems are strongly recommended to mitigate soil degradation and enhance agricultural productivity. Furthermore, this study supports the objectives of Sustainable Development Goal’s (SDGs) 15, which advocates for sustainable land use to combat soil degradation and promote ecosystem resilience.
