The full name of BB fertilizer is bulk blended fertilizer. It is a compound fertilizer made by blending several granular single fertilizers or compound fertilizers in a certain proportion.

BB fertilizer originated in the United States, due to the increase in energy prices has promoted the development of BB fertilizer. The United States, Japan, Canada, and Brazil have the most production and applications; there are 8,000 BB fertilizer manufacturers in the United States, and their output accounts for 70% of the fertilizer consumption. my country's current BB fertilizer manufacturers are mainly concentrated in Guangdong, Tianjin, Hubei and Jiangxi.

Advantages of BB fertilizer

1. The nutrient concentration is high, the output is increased, the cost is significant, and the target is strong.

Its total nutrients are generally above 52%, while the active ingredients of domestic compound fertilizers sold on the previous market are mostly around 25%, and the total nutrients of imported compound fertilizers are mostly 45%-48%, but the proportion of imported compound fertilizers (N :P2O5:K2O=15:15:15) The proportion of phosphorus is too high, resulting in a large waste of nutrients.

The nutrient distribution ratio of BB special fertilizer is proposed on the basis of considering the characteristics of crops needed for fertilizer and with reference to the local soil nutrient supply status, which is both scientific and targeted.

2. Simple processing, low production cost and no pollution.

3. The formula is flexible and can be flexibly changed according to different conditions such as crop nutrition, soil fertility and yield level, which makes up for the shortcomings of the general general-purpose compound fertilizer that is easy to cause a certain lack of nutrients due to fixed nutrient allocation ratio.

BB fertilizer can be used as base fertilizer and top dressing. Because of its good solubility, it should be applied on the surface instead of deep soil; BB fertilizer should not be spread on fruits, tea, vegetables, etc. Soil, top dressing and water can be applied. The application rate per mu is only 60% of the imported compound fertilizer.
