Agronomic co-benefits of enhanced rock weathering in smallholder farming systems of central India

Enhanced rock weathering (ERW) using silicate rock amendments represents a promising carbon dioxide removal (CDR) strategy, yet its viability in smallholder agriculture hinges on demonstrable agronomic co-benefits. Here we report findings from a farmer-participatory field trial conducted across smallholder cropping systems in central India, designed to quantify productivity responses and changes in input requirements following basalt application.Basalt rock powder (particle size
