Prospects of Micro Irrigation and Fertigation In China ’ s agriculture

The development of agriculture in Israel is strongly dependent upon the efficient use of irrigation water. Efficient use has led to a constant decrease in water consumption from an average of 8700 m/ha in 1951 to 5600 m/ha in 1990. In 1996, the Israeli farmer applies approximately 50% of the N and P2O5, and 65% of the K2O through fertigation. The Israeli experience is also applicable in China. The need for sophisticated irrigation and fertigation devices as well as training is described.
