Soil Regeneration through Permaculture: Integrating Organic Matter, Soil Microorganisms, Biochar, and Conservation Agriculture for Sustainable Soil Fertility Restoration
Main Article Content
Abstract
Background. Soil degradation is a major challenge to sustainable agricultural development because it reduces soil fertility, disrupts microbial activity, degrades soil structure, lowers water retention, and decreases agroecosystem productivity. Permaculture-based soil regeneration offers an ecological restoration strategy integrating organic matter management, soil conservation, and biodiversity enhancement.
Aims. This article analyzes soil regeneration mechanisms by integrating compost, indigenous microorganisms, biochar, nutrient-supporting plants, cover crops, organic mulching, and minimum tillage.
Methods. This conceptual review used descriptive analysis and thematic synthesis of soil regeneration materials and relevant scientific principles.
Result. The synthesis indicates that soil regeneration is a multidimensional process involving the simultaneous restoration of physical, chemical, and biological soil properties. Organic matter contributes to soil aggregation, cation exchange capacity, and substrate availability for soil organisms. Microorganisms facilitate organic matter decomposition and nutrient cycling, while biochar may improve selected soil properties depending on its characteristics and environmental conditions. Cover crops and reduced soil disturbance help control erosion, protect the soil surface, and support biological activity.
Conclusion. This article proposes an Integrated Permaculture-Based Soil Regeneration (IPSR) conceptual framework linking regenerative management practices, soil health restoration, and agroecosystem resilience. The proposed framework requires empirical validation across different soil types and agricultural systems.
