Revolutionizing Soil Health: Integrative Approaches in Microbiome Engineering, Carbon Sequestration, and Ai-based Diagnostics For Sustainable Agriculture

Abstract

Soil health has emerged as the cornerstone of sustainable agricultural productivity in the face of mounting challenges such as land degradation, nutrient depletion, climate change, and biodiversity loss. Traditional soil management techniques, while foundational, are no longer sufficient to meet the demands of global food security and ecological resilience. This review delves into an integrative framework combining soil microbiome engineering, biochar and organic amendments, carbon sequestration strategies, and AI-driven diagnostic tools to transform the way we assess, manage, and restore soil health. Recent advancements in metagenomics and microbiome editing have revealed that specific microbial consortia can significantly influence nutrient cycling, plant growth, and pathogen resistance. At the same time, the potential of soils as carbon sinks is being revisited through biochar application and regenerative practices that support long-term carbon storage. Globally, nearly 33% of soils are moderately to highly degraded, while field studies in India show that adoption of conservation tillage and residue management can sequester up to 0.3–0.5 Mg C ha⁻¹ yr⁻¹. Furthermore, AI-powered models, leveraging soil data analytics, remote sensing, and machine learning, are opening new frontiers in real-time soil monitoring, predictive nutrient management, and precision restoration. This comprehensive review synthesizes recent scientific breakthroughs and practical innovations from multidisciplinary sources, aiming to offer a transformative roadmap for future soil science research and policy-making. The convergence of biological, ecological, and digital technologies in soil health management is not just a scientific necessity but a global imperative. This article proposes a paradigm shift from reactive soil treatment to proactive soil health forecasting, with the potential to redefine agricultural sustainability at scale.
