Compound Fertilizer

Nitrogen, phosphorus and potassium , there are at least two nutrients in the three nutrients showed that the amount of fertilizer made of chemical methods, it is also a kind of compound fertilizer .

Compound fertilizer has high nutrient content and less vice composition and physical properties is good for an advantage, for balancing to fertilize, improving the utilization rate of fertilizer and promoting high and stable yield of crops has a very important role.

But it also has some disadvantages, such as it is always a fixed proportion of nutrients, and that needed for different soil and crop nutrition element types, quantity and proportion is varied. Before fertilizing ,we have the best to place a soil testing, therefore, we can understand the field soil texture and nutritional status.

Except that we can also pay attention to the unit of fertilizer application to obtain the better effect. With the increasing of food production, the phenomenon of soil nutrient deficiency is showing, farmers now choose more multivariate compound fertilizer .

Soil testing is more used to current compound fertilizer production formula to measure the soil nutrient, and it has soil testing and fertilizer field experiment as the foundation, according to the practices
