Soil Remediation and Improvement through the Application of By-Product Amendments

This Reprint compiles recent research on the remediation and improvement of soils through the application of by-product amendments. The contributions address the dual challenge of soil degradation and waste overproduction by exploring how organic and industrial residues can be repurposed to restore soil health and enhance fertility. The articles cover a wide range of contexts, from contaminated mine soils to agricultural lands, and assess impacts on nutrient availability, microbial communities, crop productivity, and pollutant mitigation. Several studies also integrate techniques such as phytoremediation and vermicomposting. This Reprint highlights interdisciplinary approaches that connect biotechnology, ecology, and sustainable waste management, offering practical perspectives for regenerative agriculture and circular economy strategies.
