Abstract

To increase rice production in Tanah Laut Regency, one of the programs implemented by the Tanah Laut Regency Government is the development of swamp irrigation areas in Sabuhur Village. Sabuhur Village has a large swamp area, which has great potential to be developed as agricultural land. However, the success of this development is highly dependent on the suitability of the soil for use as agricultural land. Therefore, testing the physical and chemical characteristics of the soil is a crucial first step to identify the potential and constraints that may occur. The method used is field sampling and laboratory testing. Based on the test results, it can be seen that the characteristics of the physical and chemical properties of the soil at the research location. In terms of soil physical properties at the location, it can be known that soil permeability ranges from 1.86-3.64 cm/h (silty clay), bulk density ranges from 1.01-1.46 g/cm3 (most have exceeded critical values for agriculture), particle density ranges from 1.9-2.86 g/cm3 (mineral soil conditions), porosity ranges from 38.83%-63.31% (silty clay), and aggregate stability ranges from 14%-62.8%. As for the chemical properties of the soil, the total Fe content ranges between 112.19-507.47 ppm, pyrite content between 0.004-0.053% (small pyrite content), CEC ranges between 16.15-30.81 me/100gr (moderate to high soil clay content), and moisture content ranges between 4.88%-29.03. Therefore, the sampling location is not a swamp area because it is mostly mineral soil with a small moisture content. The observation location is a permanently submerged wetland environment.

Abstract

Arbuscular mycorrhizal fungi (AMF) form associations with more than 80% of the terrestrial plants. These associations enhance nutrient sequestration and plant resistance to environmental stress. The diversity of AMF is highly influenced by the host plants. The types of AMF in the Bululawang, Kidang Kencana, and Pasuruan Jengkol 922 sugarcane varieties grown in a similar location were identified through morphological and molecular methods. AMF spores were isolated by the wet sieving method. The morphological features of the AMF spore mounted in PVLG and Melzer’s reagent were observed under a microscope. The DNA of the fungi was extracted, and the ribosomal RNA genes were amplified by nested PCR with the NS1-NS4 primer pairs, followed by the AML1-AML2 primer pairs. A moderate diversity of AMF was observed, with a total of 269 spores found in the Kidang Kencana variety, 191 spores in the Bululawang variety, and 142 spores in the Pasuruan Jengkol 922 variety. Four AMF species have been identified morphologically and molecularly, namely Glomus flavisporum, Acaulospora koskei, Gigaspora Margarita, and Scutellospora savannicola. These findings indicate that the number and type of AMF associated with sugarcane roots are influenced by plant varieties, in which the Glomus sp. is the dominant species in the three sugarcane varieties studied.

Abstract

Ultisol is soil on acidic dry land which has problems such as low organic matter content, soil pH and availability of nutrients, one of which is P-available. Chicken manure and coal ash can function as ameliorant materials so that they can improve fertility in ultisol soil. This research aims to determine the effect of applying ameliorant (chicken manure and coal ash) on the acidity and P availability of ultisol soil. This research used a single factor Completely Randomized Design method with six treatments repeated four times to produce 24 experimental units including PA0 = control, PA1= 100% coal ash (0,25 t ha-1) + 0% chicken manure (0 t ha-1), PA2= 25% chicken manure (0,5 t ha-1) + 75% coal ash (0,75 t ha-1), PA3= 50% chicken manure (1 t ha-1) + 50% coal ash (0,50 t ha-1), PA4= 75% chicken manure (1,5 t ha-1) + 25% coal ash (0,25 t ha-1), PA5= 100% chicken manure (2 t ha-1) + 0% coal ash (0 t ha-1). Providing ameliorants in the form of chicken manure and coal ash can expand soil pH, available P and Ca-dd, can reduce soil Al-dd but cannot expand soil Mg-dd.

Abstract

The organic farming system has become the choice of most farmers in Indonesia because it has a major impact on agricultural quality and soil fertility. Vegetable farming in Magelang and Semarang Regencies is cultivated on andisol soil which has a relatively high soil fertility level, but farmers still use organic fertilizers to increase the organic matter content of the soil. The organic farming system applies 10 tons ha-1 of cow manure, 20 liters ha-1 of liquid fertilizer, and the return of plant residues at each planting season. The conventional farming system with high organic matter applies 7 tons ha-1 of cow manure, 50 kg ha-1 of urea, 50 kg ha-1 of NPK fertilizer, 15 liters ha-1 of liquid fertilizer, while the conventional farming system with low organic matter applies 3 tons ha-1 of chicken manure, 50 kg ha-1 of ZA fertilizer, 50 kg ha-1 of KCl fertilizer, and 50 kg ha-1 of NPK fertilizer. Observation variables include pH NaF, C-organic, N-total, C/N ratio, humic acid, fulvic acid and humification rate. Data were analyzed for variety and if different, the method of the smallest significant difference test was continued. The results of the study showed that the organic farming system was more effective in increasing carbon and nitrogen in the soil and accelerating humification, so that nutrients were available more quickly. However, the deeper the soil layer, the mineralization and humification processes will decrease because they are greatly influenced by the availability of organic matter.

Abstract

This study aimed to determine the effect of pyrolysis methods on the biochar yield from oil palm empty fruit bunches (EFB) using variations in material form and combustion systems. The research was conducted from March to May 2025 in Sorek Satu, Pelalawan Regency, Riau Province, and in the Soil Science Laboratory, Faculty of Agriculture, Riau University. The study consisted of several treatments: (1) whole EFB – external semi-vacuum combustion, (2) shredded EFB – external semi-vacuum combustion, (3) whole EFB – total internal vacuum combustion, and (4) shredded EFB – total internal vacuum combustion. Collected data from the study were analyzed using descriptive statistics. The results showed that external semivacuum pyrolysis produced a higher biochar yield compared to total internal vacuum pyrolysis, with the highest yield from whole EFB at 45.6% and shredded EFB at 32.8%. The total internal vacuum system failed to produce biochar and only resulted in dry material without undergoing carbonization. The chemical characteristics from the external semi-vacuum combustion system indicated that biochar from whole EFB had higher contents of carbon, potassium, magnesium, boron, and pH, while biochar from shredded EFB tended to have higher contents of nitrogen, calcium, and iron.

Abstract

Tawangmangu District, Indonesia, is located in a highland area with a cool climate and is predominantly composed of Andisol soil types, offering great potential for the development of potato crops (Solanum tuberosum L.). This study aims to examine soil physical properties suitable for potato cultivation, analyze the distribution of these properties across different slope gradients, and identify appropriate soil management strategies for the Tawangmangu area. The research employed a descriptive-exploratory approach, utilizing land map units (LMUs) that were determined through the overlay of soil type maps, rainfall data, slope gradients, and land use. The overlay resulted in 5 LMUs and 25 sampling points. Observed soil physical parameters included texture, porosity, permeability, consistency, effective soil depth, coarse material, and drainage. The land suitability assessment showed that LMUs 1, 2, and 3 were classified as S3-oa, limited by drainage, while LMUs 4 and 5 were classified as S3-oa,rc, limited by both drainage and effective soil depth. Slope gradient significantly affected moisture content (p = 0.022), bulk density (p = 0.037), particle density (p = 0.048), porosity (p = 0.032), effective soil depth (p = 0.001), and coarse material content (p = 0.032). Recommended land management efforts include the addition of organic matter, manual tillage for shallow soils, and the application of eco-drainage techniques to improve soil physical suitability for potato cultivation in Tawangmangu.

Abstract

The increasing demand for food has driven agricultural intensification, particularly through the use of phosphate fertilizers. However, phosphorus uptake efficiency by plants remains low due to its predominance in insoluble forms in the soil. One promising alternative is the use of phosphate-solubilizing bacteria (PSB). This study aimed to evaluate the solubilization potential of the BPF9 isolate through qualitative and quantitative assays, as well as growth curve profiling. The research was conducted at the Soil and Environmental Biotechnology Laboratory, IPB University. Qualitative phosphate solubilization was assessed on Pikovskaya agar by measuring halo zone formation to calculate the solubilization index (SI). Quantitative analysis was carried out using spectrophotometry at 660 nm. The bacterial growth curve was analyzed using the haemocytometer method. Results showed that BPF9 had a solubilization index of 2.0 (moderate category) and was able to solubilize phosphate up to 128.5 ppm, which is considered highly efficient. The growth curve indicated that BPF9 entered the exponential phase at 26 hours and reached its maximum population at 42 hours. These findings indicate that BPF9 possesses strong phosphate-solubilizing capability and stable growth characteristics, making it a promising candidate for biofertilizer development.

Abstract

Soil fumigation is important pre-plantation practices to maximize land productivity. Not only effectively eliminate soil pests and pathogens, but this practice also affecting the beneficial soil microbial community including arbuscular mycorrhizal (AM) fungi. The AM fungal community in the roots of Allium fistulosum were studied. The roots have been collected from fumigated and non-fumigated field. The DNA has been extracted, then the fungal LSU ribosomal RNA gene has been amplified and sequenced. Two and three AM fungal OTUs have been detected from fumigated and non-fumigated field, respectively. Decomposer and pathogenic fungi were detected coexist with the AM fungi, suggesting the resilience of these fungi upon fumigation treatment.

Abstract

Soil contamination by heavy metals poses a significant threat to sustainable agriculture, especially in areas adjacent to industrial zones. This study demonstrates that while the initial application of the biosilica-humic acid (BSi-HA) soil amendment did not result in statistically significant changes in soil chemical properties within the first 7 days of incubation, prolonged incubation for 60 days revealed meaningful effects, particularly in reducing heavy metal availability in soil. Significant decreases in iron (Fe) and lead (Pb) concentrations were observed over time, with Fe reductions ranging from 45–67% and Pb reductions between 8–40%. These results are attributed to the synergistic effect of functional groups in BSi-HA—especially the carboxyl (–COOH) and hydroxyl (–OH) groups in humic acid—which exhibit high metal-binding affinity under acidic conditions (pH ~5). Although soil fertility parameters such as C-organic content and cation exchange capacity (CEC) showed a declining trend due to microbial activity during incubation, the ability of BSi-HA to immobilize heavy metals without exceeding safe thresholds highlights its potential as a sustainable soil amendment. Moreover, previous findings indicating reductions of up to 90% for Pb and 76% for Cd in plant tissues further support the efficacy of BSi-HA in mitigating heavy metal contamination in agricultural soils near industrial zones. Further long-term studies are recommended to evaluate BSi-HA's remediation capacity, persistence, and impact on crop yield and food safety. Combining biosilica and humic acid offers a promising, eco-friendly approach for managing heavy metal contamination in soils.

Abstract

Soil is a fundamental factor influencing agricultural productivity, as it determines nutrient availability, water retention, and the long-term sustainability of farming systems. The Bareng Wonosalam District of Jombang Regency is a significant agricultural area with varied topography and intensive land use; however, comprehensive soil characterization in this region remains limited. This study aimed to analyze the physical and chemical characteristics of soils in plantation lands and classify them taxonomically to inform sustainable management. A representative plantation site in Pulosari Dua was selected using land-use and slope overlays. Five soil horizons (Ap, AB, Bt1, Bt2, BC) were described. Samples were analyzed for moisture content, texture, bulk density, pH (H₂O, KCl), electrical conductivity, organic carbon, total nitrogen, available phosphorus (Olsen, Bray), exchangeable cations (K, Na, Ca, Mg), cation exchange capacity (CEC), and base saturation (BS). Results showed moisture content of 6.2–20.8%, bulk density of 1.23–1.52 g/cm³, pH of 5.35–5.99, and organic carbon of 0.77–3.61%. Exchangeable K and Na were low (<0.60 cmol·kg⁻¹), while Ca ranged from 3.69–7.06 cmol·kg⁻¹. Textures were silty clay and clay, with BS of 53.5–117.1% and CEC of 9.15–12.93 cmol·kg⁻¹. The soils were classified as Typic Hapludalfs. Recommended practices include dolomite liming, potassium fertilization, structural amendments, and terracing. These actions are expected to enhance soil fertility, water retention, and plantation productivity by enabling targeted soil amendments, balanced nutrient application, and erosion control measures that directly address the identified limitations.
