Nutrient-based Organic Formulations for Sustainable Crop Nutrition and Soil Health: A Critical Appraisal of Mechanisms, Agronomic Evidence and Unresolved Constraints
Nutrient-based organic formulations occupy an expanding but conceptually unsettled position between bulk organic amendments and manufactured mineral fertilisers. The category now includes enriched and fortified composts, vermicomposts, organomineral granules, biochar-based composites, anaerobic digestates, microbial inoculant formulations, and non-microbial biostimulants derived from seaweeds, humic substances and protein hydrolysates. These products are promoted simultaneously as nutrient carriers, soil conditione …
