Bio-Based Seed Coating
report_problem Problem Statement
Commercial seed coatings rely on synthetic polymers like polyvinyl alcohol and polyacrylamide to bind pesticides, nutrients, and inoculants to seeds. These coatings can leave persistent microplastic residues in soil and may inhibit beneficial microbial colonization. A bio-based coating using naturally-derived compounds could provide equivalent adhesion and controlled release while fully biodegrading in soil.
