Abstract

This community service program was implemented at the Sabilus Salam Sharia Cooperative, Notorejo Hamlet, Wonosalam District, Jombang Regency, East Java. It involved 25 farmers and 10 cooperative members, and was facilitated by a service team consisting of four lecturers and one master’s (S2) student. The uniqueness of this program lies in the utilization of kascing (earthworm castings) based on the local wisdom of Wonosalam, integrated with the use of local organic waste and the strengthening of cooperative institutions through a Participatory Action Research (PAR) approach. This distinguishes the program from conventional organic fertilizer training, which is typically one-directional. The objective of the activity was to enhance farmers’ capacity to produce and apply both liquid and solid organic fertilizers based on kascing, in order to reduce dependence on chemical fertilizers and improve soil quality. The methods employed included socialization, participatory training, field assistance, and experimental demonstration plots. Standardized laboratory test results indicated an increase in soil pH from 3.25 to 5.42, organic carbon (C-organic) from 0.23% to 0.53%, as well as improvements in the levels of nitrogen, phosphorus, and potassium. Post-training evaluation showed that 84% of participants understood the stages of kascing fertilizer production, and 72% had applied it on their respective farms. Overall, the program proved effective in measurably improving soil quality and strengthening the independence of farmers and the cooperative in developing sustainable agriculture based on local resources..

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.
