Under plastic film drip irrigation is extensively employed in cotton crop planting in Xinjiang, China. Fertigation is one of the core techniques of water saving irrigation. The ideal fertilizer used for fertigation should be highly dissoluble in order to avoid blocking of dripping tunnel of drip pipe. Cotton special fertilizers are kinds of novel compound fertilizer which well fit the drip irrigation system and nutrition need of cotton crop under drip irrigation. The main objective of this study was to evaluate the mobility of N, P and K elements of both special fertilizer and formal fertilizer in soil and cotton use efficiency under drip irrigation. Field experiments were conducted in Shihezi, Xinjiang in 2006. The results indicated that N, P and K elements of special fertilizer were more movable in soil than that of formal fertilizer under fertigation and their distributions in soil were fit for cotton root distribution. Use efficiency of N, P and K of special fertilizer were enhanced to some degree by fertigation. Physiological use efficiencies of N, P and K of special fertilizer compared with that of normal fertilizer were increased by 3.62%, 4.18% and 1.45%, respectively. Agronomic efficiency of N, P and K of special fertilizer compared with that of normal fertilizer were increased by 29.37%, 29.2% and 29.38%, respectively. Compared with normal fertilizer applying treatment, the seed cotton yield of special fertilizer one was increased by 6.9%.
