| Abstract: | Chemical fertilizer Industry of China has already made great progress since 1949. By 1993, the total fertilizer production capacity that has been built was 27.8 Mt, including 20.9 Mt of N, 6.73 Mt of P2O5, and 200 thousand t of K2O. The accumulated ammount of fertilizer nutrients applied into soil during 1949-1993 was 380.6 Mt of which 90 Mt was imported accounting for 23.6% of the total. It is estimated that by the end of the century 42 Mt of fertilizer would be needed to meet the requirement of agricutural production in China. It's supply should mainly rely on China's own Industry. The average nutrients content of fertilizer of China is 26.5% now which is still much lower than the world average (about 40%).So China should pay even greater attention to the production of higher grade fertilizers. A few low grade fertilizers like single superphosphate and NH4HCO3 will still be important sources in Ghina in the near future. Improvement of technigue of fertilizer production in order to lower the energy comsumption and better equipment for the industry are also the main proints needed to. solve. |
