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.

flag Success Criteria

Achieve ≥95% germination rate (matching uncoated control), dust-off ≤2% by weight after tumble test, coating degradation >80% by mass in soil within 90 days, and uniform coat thickness of 20-50 μm verified by SEM cross-section

precision_manufacturing Equipment Needed

Laboratory pan coater or fluidized bed coater, SEM for coating characterization, seed germination chamber (25°C, humidity controlled), analytical balance, tumble test apparatus, soil incubation containers, stereomicroscope, viscometer for coating solution characterization
