The first is multi-species specialization. Different crops have different special fertilizer,which production is based on the growth and development of crops, when choosing compound fertilizer, farmers should choose special fertilizer according to different crops.

The combination of pesticides and fertilizers eliminates the mixing procedure of pesticides, and the one-time application can not only guarantee the nutrients needed by crops, but also prevent and control underground pests and seedling diseases, which can have multiple effects.

The third is long-term and high concentration. With the development of agricultural production, high-concentration and long-effect compound fertilizer is more and more popular among farmers. The application of this type of fertilizer reduces the amount of fertilizer, makes it convenient to cultivate, eliminates the need to apply fertilizer, reduces the amount of labor, improves the utilization rate of fertilizer, saves labor, labor and time, improves the quality and efficiency. our high-quality and one complet set of compound fertilizer production line will provide all these requirements. It includes,roller press granulator production line, and npk compound fertilizer production line. You can choose one suitable type according to your requirement, we also provide custom-tailor sevice for our customers.

1.High nutrition content and major nutrient elements of compound fertilizer, with various types of element, at least it can provide more than 2 types of major nutrient elements for crops in one tim application.  

2.Minor nutrient element is less, structure is uniform. For example, ammonium phosphate does not contain any useless subcomponents, and its anions and cations are the main nutrients absorbed by crops. The distribution of nutrients in this fertilizer is relatively uniform. Compared with the powdered or crystalline unit fertilizer after granulation, the structure is close, the nutrient release is uniform, and the fertilizer efficiency is stable and long. The adverse effect on the soil is small due to less secondary components.

3.Good physical characteristics, compound fertilizer manily is made into granules, with small hygroscopicity, not easy to cake, convenient to store , apply into soil automatically.

4.Save the expense of storage, transportation, package. Active ingredient content is higher than the usual fertilizer in the compound fertilizer, so it can save the expenses of storage, transporation and package. For example,   the storage each ton of ammonium phosphate is approximately equal to 4 tons of calcium superphosphate and ammonium sulfate. 

1.the nutrient proportion is fixed, is hard to satisfy the need of different types of soil and crop.

2. the nutrient rate of movement is different in the soil,  the extent maintained and lapsed in the soil is different, so the application time and site is hard to meet the requirements of  application technology.
