Abstract: Fertilizer is an important source of necessary nutrient element for crop growth. Coated fertilizer can not only achieve the slow/controlled release and increase nutrient use efficiency but also enhance the strength of fertilizer particles and reduce transport losses. The coating technology and evaluation methods for slow-controlled release efficiency of slow/controlled release fertilizer were summarized. Furthermore,problems in practical application and corresponding solutions were introduced, which laid the foundation for the research of slow-controlled release efficiency of slow/controlled release fertilizer in the future.

Key words: slow/controlled release fertilizer, coating technology, evaluation methods, progress
