Abstract

Food security remains a critical global challenge, particularly as land degradation, driven by excessive use of synthetic fertilizers, continues to threaten soil fertility and crop productivity. This study aimed to evaluate the characteristics of liquid and semi-solid fermented organic waste and their effects on several soil chemical properties and sweet corn yield. The experiment was conducted in a corn field in Pagerwangi Village, West Java, Indonesia. The experiment used a Split-Plot Design with three replications. The main plot was the fermented waste product treatment, which consisted of three levels: no product (A0), liquid product (A1), and semi-solid product (A2). The subplot was the N-P-K dose level, which consisted of four levels: 0 N-P-K (a0), 1/2 N-P-K dose (a1), 3/4 N-P-K dose (a2), and standard N-P-K dose (a3). The research findings indicated that the macro and microelements present in semi-solid products were several times higher compared to liquid ones. Furthermore, the microbial population in semi-solid products exhibited higher density compared to liquid products. Field tests also demonstrated that both liquid product (A1) and semi-solid product (A2) significantly increased total nitrogen, organic-C, and soil pH compared to the control (A0). The highest sweet corn productivity was observed in treatment A2, with a yield increase of 47.62% compared to the control. The research results suggested that the use of fermented organic waste products could enhance soil fertility and sweet corn production.

Abstract

The loss of topsoil in high-rainfall regions significantly reduces agricultural productivity, especially in degraded soils. This study investigated the effects of Mixed Fertilizer-Conditioner (MFC) on improving the chemical properties of subsoil cultivated with red chili peppers. A Randomized Block Design (RBD) with 11 treatments on subsoil and one control on normal soil was implemented, with three replications. The treatments included: A= subsoil without fertilizer, B= 0% MFC + full NPK, C= 25% MFC + full NPK, D= 50% MFC + full NPK, E= 75% MFC + full NPK, F= 100% MFC + full NPK, G= 50% MFC + 75% NPK, H= 50% MFC + 50% NPK, I= 50% MFC + 25% NPK, J= 50% MFC without NPK, and K= Full NPK on normal soil. The application of 100% MFC combined with full NPK significantly enhanced subsoil chemical properties. Soil organic carbon increased to 1.32%, pH rose to 6.3, CEC reached 22.1 cmol kg⁻¹, and base saturation improved to 49.4%. Nutrient availability also increased, including total N (1.21%), P (0.132%), K (0.677 cmol kg⁻¹), along with Ca (1362.72 ppm), Mg (311.04 ppm), and S (36.01 ppm). Micronutrients B, Co, and Zn also rose to 4.41 ppm, 18.95 ppm, and 11.97 ppm, respectively. Chili yields in subsoil treated with 50–100% MFC and full NPK exceeded 10 tons ha⁻¹. These results highlight the agronomic potential of MFC for rehabilitating degraded soils and recommend its use as a sustainable strategy to enhance soil fertility in low-fertility or erosion-prone areas, with implications for both farmers and agricultural policymakers.
