Abstract:
     Full-elements fertilizer, or complete nutrient for plant, contains 6 normal nutrient elements and 11 micro-nutrient elements required for plant growth. It is produced by formulating, mixing, stirring, pulverizing and activation. It is packed into commercial fertilizer. During preparation, raw materials must be elaborately selected to prevent antagonism among various elements which may reduce fertilizing efficiency, even may be harmful to crops. The ratio of elements in fertilizer should be properly adjusted according to soil condition, pH value, state of fertilizer application, kinds of crops and their growth period, as well as weather condition.
