It is forecasted that total amount of fertilizer is stable or decreased, it is proposed that slow/ controlled release fertilizer, secondary and micro-element fertilizer, organic fertilizer, organic-inorganic compound fertilizer, liquid fertilizer should be developed especially, the low analysis phosphate fertilizer should be preserved.
