A survey on the amount and method of fertilizer application in paddy field from rice farmers in Taichung District was conducted in 1990-91. A total of 1,150 rice famers randomly sampled from 3 counties and 1 city of Taichung District was interviewed with regard to their habit of fertilization in paddy field. The results of survey indicated that most farmers applied N fertilizers 4 times and 2 times for P and K fertilizers, the kind of practice of fertilizer application was found to the same in the culture of Japonica, Indica and Glutinous types of rice. The amounts of fertilizer applied were 220 kg/ha of N, 60 kg/ha of P2O5 and 110 kg/ha of K2O. The rice farmers in Changhwa tended to apply an excess amount of N fertilizer in comparison with other locations. The compound fertilizer such as Taiwan Fertilizer N0. 1 (20-5-10), Taiwan Fertilizer No.5 (16-8-12) and Taiwan Fertilizer No. 39 (12-18-12) were found to use increasingly in comparison with the single nutrient fertilizers.
