The using conditions and developing directions of Chinese phosphorous fertilizer

In recent years,the rapid development of high analysis phosphorous fertilizer have influenced the developing of low analysis phosphorous fertilizer,although it have brought the flourishing development of phosphorous fertilizer industry.From 2000 to 2004,the low analysis phosphorous fertilizer leveled off with the outputs of 4,280,000(4,680,000 t) P_2O_5,while the proportion in the total output of phosphorous fertilizer was dropped from 64.6% to 46.0%.The conditions of low analysis phosphorous fertilizer's manufacture,use and resources utilization were studied base on the inquisitional and statistical data.It shows that the inconsistency between the steady outputs of low analysis phosphorous fertilizer and the rapid demand of all kinds of nutrient for agricultural production can increase the market room of low analysis phosphorous fertilizer.It also indicates that the inconsistency between the phosphate demand of low analysis phosphorous fertilizer and the usability of phosphate rock can bring great development in future.In addition,improving the cost performance of the products through checking and calculating the trace element value in low analysis phosphorous fertilizer is possible ways to protect the healthy development of low analysis phosphorous fertilizer industry.In a word,the adjustment of the structure of the phosphorous fertilizer industry at the present stage,farmer's know with low analysis phosphorous fertilizer and the improving of enterprise's engineering and management level can make great influence on the healthy development.
