Abstract

This study aims to assess the impact of Organic FertilizerPlus on soil fertility status, nutrient uptake, and soybean yield in Alfisol. The research employs a randomized complete group design (RCGD) with a single factor, consisting of P0 (Control), P1 (Cow dung, 5 tons ha-1 + Zeolite dose of 2.5 tons ha-1), P2 (Cow dung, 5 tons ha-1 + Zeolite dose of 5 tons ha-1), P3 (Cow dung, 5 tons ha-1 + Dolomite dose of 2.5 tons ha-1), P4 (Cow dung, 5 tons ha-1 + Dolomite dose of 5 tons ha-1), and P5 (Cow dung, 5 tons ha-1 + Zeolite dose of 5 tons ha-1 + Dolomite dose of 5 tons ha-1), repeated four times. The results indicate that the application of Organic FertilizerPlus enhances soil fertility status (pH, organic C, CEC, and available P), with the highest values observed in treatment P5, including pH (6.70), soil organic C (6.28 g.kg-1), cation exchange capacity (CEC) (6.85 cmol.g-1), and available P (2.63 mg.g-1). This leads to increased phosphorus uptake, consequently improving soybean yields. The highest soybean yield is achieved by applying Organic FertilizerPlus (P5) at 2.17 t.ha-1.

Abstract

Bagasse, one of the largest agricultural wastes with suboptimal utilization, could improve Entisols in the tropics by enhancing soil fertility and crop productivity. This study aimed to determine the changes in humic substances and nutrient levels in Entisols and their effects on shallot yield. The study was designed using a completely randomized design, consisting of four treatments of organic matter combinations with NPK fertilizer, four single organic matter treatments, one standard NPK fertilizer dose, and one control. Each was replicated three times. The results showed that using bagasse improved soil conditions by increasing C content and nutrient levels in the soil, enhancing nutrient absorption by plants, and consequently boosting crop yields. The biochar + bagasse compost (2:4) (bio-compost) + NPK resulted in high soil organic C, humic acid, fulvic acid, nutrient availability, and plant nutrient levels, which were comparable to the manure treatment, and significantly increased shallot yield in Entisols. The findings of this study could support the development of nutrient management strategies utilizing bagasse as a potential soil amendment for Entisols.
