Abstract

Inceptisol is a widespread soil with a total of 37% of the land area in Indonesia. On the island of Java, Inceptisol has an intensive management intensity, one of which is in Kertasari District, Bandung Regency, West Java, which has a high potential for soil damage due to a decrease in the soil's ability to hold water. Biochar enriched with silica and activated charcoal Oil Palm Empty Fruit Bunches (OPEFB) is a type of organic soil amendment that can improve the ability of Inceptisol to hold water and support nutrient needs through organic C indicators and cation exchange capacity. The research was carried out by taking soil samples and then incubating them according to the treatment for 14 days. The experimental design used in the study was a non-factorial, Completely Randomized Design (CRD) method with 12 levels consisting of 3 L/ha of silica-enriched rice husk biochar and OPEFB's activated charcoal, with each in the range of 0-6.25 tons/ha. Measurement results of water holding capacity parameters, C-organic, and cation exchange capacity were analyzed statistically, and significant differences in responses were obtained from the treatments. The optimum dose for Inceptisol in Kertasari uses silica-enriched biochar to increase water holding capacity, organic C, and cation exchange capacity, respectively, at 4.92 tons/ha, 5.73 tons/ha, and 2.51 tons/ha. Otherwhile, OPEFB's activated charcoal was 1.7 tons/ha, 0.125 tons/ha, and 1.5 tons/ha, respectively.

Abstract

Urea Fertilizer doses are a significant factor in sorghum production. This research was conducted to study soil characteristics and sorghum production through the applications of urea fertilizer doses in Latosol soil. This research was conducted from May to September 2019 in the KST GA Siwabesy experiment field at Pasar Jumat, South Jakarta. The design used in this study was a randomized block design (CRD) with 4 treatments in the form of fertilizer N doses of 0 kg ha-1, 50 kg ha-1, 100 kg ha-1, and 200 kg ha-1. The results showed that applying N fertilization did not affect soil pH, soil P available, soil organic C, soil N total, C/N ratio, CO2 content, and soil nitrate content. N fertilization significantly affected the number of functional microbes, Azotobacter and Phosphate Solubilizing Microbes (MPF). In addition, N uptake of sorghum and dry weight of sorghum seeds increased significantly by 5.54 times and 2.29 times, respectively, from control when urea fertilizer was applied to 200 kg urea ha-1.

Abstract

The addition of phosphate-solubilizing microorganisms (PSM) as biofertilizers can improve the quality of soil properties. A meta-analysis study was conducted to analyze the effect of PSM on soil properties. This meta-analysis has analyzed 20 research articles published between 1990 and 2023, which have reported the influence of PSM on soil properties. The value of effect size (ES) Hedges'd of available-P is 3.047 (p<0.001), ES of available K is 2.102 (p<0.001), ES of soil nitrogen (N) is 1.706 (p<0.001), ES of pH is  -2.738 (p<0.001), ES of soil organic carbon (SOC) is 1.087 (p=0.004), ES of N-NH4 is 0.636 (p= 0.013), ES of N-NO3 is 2.643 (p< 0.001), ES of phosphatase is 5.001 (p< 0.001), ES of alkaline phosphatase is 22.956 (p<0.001), and ES of acid phosphatase is 23.104 (p<0.001). The results showed that in terms of phosphate solubility, PSM is more effective on alkaline soils with high SOC content, very high P availability, and a sandy loam texture. PSM is more effective for K solubility on acidic soils, with very high SOC content, high P availability, and a loamy texture. PSM is effective in increasing soil N with acid soil characteristics, low SOC content, moderate available P content, and clay texture. According to this study, the Penicillium fungus ranks second in the fungal group in terms of phosphate solubilization capacity after the genus Azotobacter. The genus Peronospora showed the greatest potential in increasing soil N. In contrast, Burkholderia showed the greatest effectiveness in solubilizing K.

Abstract

Productivity of crops such as maize and sorghum is often constrained by low soil fertility, especially in terms of nutrient availability. Arbuscular Mycorrhiza Fungi (FMA) can improve nutrient absorption and support plant growth through a symbiotic relationship with plant roots. However, the success of FMA colonisation is strongly influenced by the quality of the growing medium, which is often contaminated with competing microorganisms that inhibit its effectiveness. To address this issue, this study aimed to evaluate the effect of sterilisation methods on the colonisation of FMA in maize and sorghum plants. The sterilisation methods tested were autoclaving and gamma radiation. This study used a completely randomised design with 8 treatment combinations and 5 replications. Zeolite media was sterilised using autoclaving and gamma radiation at a dose of 50 kGy. Results showed that sterilisation with gamma radiation produced a higher number of mycorrhiza spores and increased root colonisation in maize and sorghum compared to autoclaving. Gamma radiation applied to one sorghum seedling resulted in the highest spore count, while two seedlings in one pot reduced colonisation efficiency due to competition for nutrients. Gamma radiation was more effective in improving the quality of growing media and supporting mycorrhiza colonisation, ultimately enhancing overall plant growth and nutrient absorption.

Abstract

Sidenuk rice is a superior rice variety produced by BATAN through a radiation mutation technique.             The new varieties that have been produced need to be supported by efforts to optimize production through fertilization technology. The purpose of this study was to determine the effect of organic fertilizer which can increase growth, production and reduce the use of urea fertilizer in lowland rice optimally. The study was conducted using a completely randomized design. Each was repeated 4 times so that the total experimental unit (pot) was 32 rice pots. The treatments include (1) Control (without urea fertilizer),              (2) Control (+) 100% urea, (3) 50% urea, (4) Local microorganisms (MOL), (5) Compost, (6) Biochar , (7) Azolla, (8) Mol + Compost + Biochar + Azola + SP 36 and KCl. The results showed that the highest grain weight was found in the 100% urea treatment, which was 43.97 g plant-1. MKBA treatment    (MOL fertilizer, compost, biochar, azolla) showed values that were not significantly different from 100% urea treatment. Organic fertilizer formula (MOL fertilizer, compost, biochar, azolla) can reduce the use of urea fertilizer by 50%.

Abstract

Shallots are a high-value horticultural commodity that requires optimal phosphorus (P) availability tosupport growth and bulb production. However, Inceptisol soils have limitations in providing phosphorusdue to their high fixation capacity and low organic matter content. This study aimed to examine the effectof liquid NPK fertilizer application on soil phosphorus availability, plant phosphorus uptake, and shallotbulb yield in Inceptisol soil. The experiment was conducted using a randomized complete block design(RCBD) with six treatments: control, recommended NPK fertilizer, and four doses of liquid NPK fertilizer(½, 1, 1 ½, and 2 doses), each with four replications. The results showed that liquid NPK fertilizerapplication significantly increased soil phosphorus availability, plant phosphorus uptake, and both freshand dry bulb weights compared to the control. The 1 ½-dose liquid NPK fertilizer treatment resulted in anavailable P content of 12.72 ppm, a phosphorus uptake of 3.28 mg plant⁻¹, a fresh bulb weight of 78.63 gclump⁻¹, and a dry bulb weight of 63.86 g clump⁻¹, which were not significantly different from therecommended NPK treatment. This indicates that applying 1 ½ doses of liquid NPK fertilizer can serve asan equivalent alternative to conventional granular NPK fertilizer in providing phosphorus for shallotcultivation. Thus, the application of liquid NPK fertilizer at 1 ½ times the recommended dose can beproposed as an effective and efficient fertilization strategy to improve shallot productivity in Inceptisol soil.

Abstract

The degraded Latosol soil is characterized by its acidity and low organic matter content, which limits rice productivity. Improving the chemical properties of the soil is crucial for supporting the sustainability of paddy fields. This study aimed to enhance these properties using silica-enriched biochar through gamma irradiation as a biofertilizer carrier. Rice husk biochar was selected for its resistance to decomposition and was enriched with SiO? to fulfill the nutritional needs of rice plants. The treatments tested were combinations of biochar-silica formulas (F0 = no formula, F1 = biochar-silica with rice husk ash, and F2 = biochar-silica with zeolite) and NPK fertilizer doses (R0 = no fertilizer, R1 = 50% recommended dose, R2 = 100% recommended dose). The results showed that the F1 formula combined with the full NPK dose (R2) significantly improved soil structure, increased organic carbon content, and enhanced nutrient uptake efficiency, which in turn, promoted higher rice productivity. The use of silica-enriched biochar as a carrier for biofertilizers has proven effective in supporting the sustainability of paddy soils. The F1 formula with a full dose of NPK can be recommended to enhance rice productivity while maintaining soil fertility.

Abstract

Sustainable rice farming is increasingly threatened by declining soil fertility, excessive reliance on chemical fertilizers, and environmental degradation from intensive agricultural practices. There is an urgent need for innovative organic fertilizer products that combine organic materials with macro and micronutrient enhancements to restore soil health effectively. This research aimed to evaluate the effect of organic plus fertilizer (OPF) as a sustainable soil amendment to improve soil nutrient status, increase paddy productivity, and enhance overall soil health. The experiment was conducted using a Randomized Block Design (RBD) with nine treatments: one recommended OPF dose, six combinations of NPK (75 – 100%) and OPF (75 – 150%), one recommended conventional NPK dose, and one control. Variables observed included plant growth, yield, and yield components, total soil nitrogen, and plant uptake of N, P, and K. Results indicated that OPF combined with NPK significantly increased plant height (29.13 – 31.38%) and number of panicles (57.89%) compared to the control. Nutrient uptake improved for nitrogen (23.68%) and potassium (15.96 – 21.28%), although no significant improvement was observed for phosphorus. Yield parameters showed an 81.97%–118.50% increase over the control. The combinations of 75% NPK + 150% OPF, 100% NPK + 75% OPF, and 100% NPK + 100% OPF produced taller plants, higher yields, greater nutrient uptake, and lower residual nitrogen in the soil. For optimal rice yield and soil health, integrated application of OPF with either a full or 75% NPK dose is recommended.
