Fertilizers that release nutrients slowly can provide crops with consistent nutrients, while soils good water-holding capacity alleviate the impact of droughts on crops. Sodium alginate/carboxymethyl starch sodium/polydopamine/urea (SCPU) is a new kind slow-release fertilizer water absorption property. In this study, Box–Behnken response surface methodology (RSM) was used to reveal effects concentrations sodium alginate, carboxymethyl sodium, urea, calcium chloride and dopamine encapsulation efficiency SCPU. The results show optimum preparation conditions obtain highest level (89.27%) (167.05%) are 2.2% 5% 30% 1.9% 0.52% dopamine.
