Mix large granular urea with BB fertilizer, special formulated fertilizer and partially slow-release blended fertilizer to provide suitable nitrogen fertilizer raw materials. The role of large-grain urea in crop yield, nutrient efficiency, and control of agricultural non-point source pollution also needs market attention.
