Retrospects and Prospects on Balanced Fertilization in Jiangxi Province

Based on the retrospects and existing problems of balanced fertilization in Jiangxi province, a few countermeasures on the application of balanced fertilization were put forward in this paper. First, the demand for chemical fertilizer and the proper proportions of nitrogen, phosphorus, and potassium by the end of this century were expected. Second, attention should be paid to the role of middle- and micro-nutrients in balanced fertilization. Third, organic resources should be made full use of. Fourth, the development and application of bulk blend fertilizer, which is a materialized technique of balanced fertilization, should be sped up. Finally, legislation and administration on the production and marketing of chemical fertilizer should be strenghened.
