                The easily dispersable mixture is
                convenient for amelioration of soil structure and
                pH, good source of N,P,K and micronutrients. It
                increases the yield, applicable on arable land,
                horticulture and greenhouses. The fruits and
                vegetables mature 4-6 days earlier, the sugar
                content of fruits is higher. The flowers has

            - Advantages: 
 
                The fertilizer mixture rich in macro and micro
                nutrient, it can solve the utilization of sewage
                sludge by environmentally friendly way.
