In-situ metal-chelated bio-epoxy coatings from epoxidized soybean oil and salicylic acid for controlled-release fertilizers

Key Points

• Metal-chelated bio-epoxy coatings enhance controlled-release properties for fertilizers, improving nutrient management.
• Key metric shows these coatings can release nutrients in a controlled manner when exposed to environmental stimuli.
• Analysis reveals the combinations of epoxidized soybean oil and salicylic acid create effective bio-epoxy coatings suitable for fertilizers.
• This work may enable more effective nutrient delivery in agriculture through sustainable materials and innovative formulations.
