Sustainable Soil Management for Agriculture: Conservation Agriculture, Integrated Soil Fertility Management, Organic and Regenerative Approaches, and Enabling Policies

AbstractSustainable soil management is fundamental to long-term agricultural productivity, climate resilience, and environmental sustainability. Conventional agricultural intensification has often resulted in soil degradation through erosion, nutrient depletion, loss of soil organic matter, and declining biological activity. In response, several complementary approaches have emerged to restore and sustain soil functions while maintaining farm profitability. This narrative review synthesizes four major pillars of sustainable soil management for agriculture: (1) Conservation Agriculture (CA), which emphasizes minimum soil disturbance, permanent soil cover, and crop diversification; (2) Integrated Soil Fertility Management (ISFM), which combines mineral fertilizers, organic inputs, and improved germplasm adapted to local conditions; (3) organic farming and regenerative agriculture, which prioritize soil organic matter buildup, biodiversity, and reduced reliance on synthetic inputs; and (4) policies and farmer capacity development mechanisms that enable adoption and scaling of sustainable practices. Drawing on peer-reviewed literature indexed in Google Scholar, the review evaluates evidence on soil health, productivity, and resilience outcomes, discusses trade-offs and context dependency, and highlights the importance of institutional support and farmer learning systems for successful implementation.Keywords: sustainable soil management, conservation agriculture, ISFM, organic farming, regenerative agriculture, soil health, policy, farmer capacity development
