The work aims to reduce the amount and increase the efficiency of chemical fertilizers and develop green agriculture. A novel kind of sustained release fertilizer was developed with biodegradable materials polypropylene carbonate (PPC) and poly (butyleneadipate-co-terephthalate) (PBAT) as coating materials and with urea particles loaded with SBA-15 molecular sieve as the core material. The mechanical properties, wettability, moisture and air permeability, and water absorption of the composite film were determined and the cumulative nitrogen release rate of urea was evaluated by water dissolution and soil dissolution to evaluate the embedding fertilizer comprehensively. The experimental results showed that the composite film had good mechanical properties, water retention, air permeability and rain erosion resistance, which could make the film have excellent impact resistance and water storage properties. Moreover, the cumulative nitrogen release rate on day 28 in the water dissolution experiment and the soil dissolution experiment was 61.5% and 55.5%, respectively, which satisfied with the national standard of ≤80%. In conclusion, the prepared degradable embedding sustained release fertilizer has excellent controlled release performance, low cost and environmental-friendly features. It has great potential in industrial application of sustained release fertilizers.
