Abstract: How to increase fertilizer use efficiency (FUE)and decrease environment pollution caused by nutrient losses has been concerned by the whole world for a long time. It is very important to increase FUE in China for its low FUE and serious losses of nutrient. The recent advances of the technologies to increase FUE are reviewed in this article, which include applying site-specific nitrogen management and real-time nitrogen management to fertilizer management, development of new style slowly release and controlled release fertilizer to control nutrient release，technology of site specific nutrient management and using urease inhibitor or nitrification inhibitor to decrease nitrogen losses. And some technologies to increase FUE are previewed in the future.

Key words: Fertilizer use efficiency, Site-specific／real-time nitrogen management, Slowly release/controlled release fertilizer, Site specific nutrient management, Urease/nitrification inhibitor
