Abstract：The research progresses of hydrogels applied to slow/controlled release fertilizers were reviewed.It was found that water retention and slow/controlled fertilizer with distinguished properties could be obtained by applying hydrogels to slow/controlled fertilizer,resulting in raising utilization rate of fertilizer and water resources at the same time;and the limitations to the wide application of water retention and slow/controlled fertilizer were high cost,unsuitable to industrial production and difficult to realize the complete accord between release circle of fertilizer and demand circle of crops to nutrients.By exploring mechanism and laws of fertilizer release and controlling structure and component of fertilizer,especially structure and component of hydrogels,tuning its release properties,smart retention and slow/controlled fertilizer system could be fabricated.The fertilizer system can satisfy the need of different surroundings and the growth of different crops,which will be the further focus and direction of research.
