Abstract

Regenerative agriculture practices have emerged as a promising approach to enhance soil microbiome resilience, a critical factor in sustainable food production and ecosystem health. This study investigates the impact of regenerative agricultural practices on soil microbial community structure, diversity, and functional resilience across multiple farming systems. Through comprehensive analysis of 120 soil samples from regenerative and conventional farms across three climatic zones, we employed 16S rRNA sequencing, metagenomics, and functional assays to assess microbiome composition and resilience indicators. Results demonstrated that regenerative practices increased microbial diversity by 47% (p<0.001), enhanced functional redundancy by 35%, and improved stress resistance capabilities by 52% compared to conventional systems. Notably, regenerative soils exhibited greater resistance to drought stress, with 78% maintenance of microbial activity under water-limited conditions versus 42% in conventional soils. Network analysis revealed more complex and stable microbial interactions in regenerative systems, with increased modularity (0.68 vs 0.41) and connectivity. These findings underscore the critical role of regenerative agriculture in fostering resilient soil microbiomes capable of maintaining ecosystem functions under environmental perturbations, with implications for climate change adaptation and sustainable agriculture.
