Study on the Utilization of Biodegradable Polyurethane Material from the Bark of Acacia Mearnsii (I) Coating Material of Controlled Slow-Release Fertilizer

This paper expounds a novel coating material of controlled slow-release fertilizer-biodegradable polyurethane foams (PUFs), which were prepared through the reaction of diisocyanate with Acacia mearnsii de wind bark that had been dissolved in glycol adipic
