What is BB fertilizer?
The full name of BB fertilizer is bulk blended fertilizer. It is a compound fertilizer made by mixing 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, the development of BB fertilizer has been promoted. The largest producers and applications are in the United States, Japan, Canada, and Brazil. There are currently 8,000 BB fertilizer manufacturers in the United States, and their output accounts for 70% of chemical fertilizer consumption. At present, BB fertilizer manufacturers in my country are mainly concentrated in Guangdong, Tianjin, Jiangxi and other places, with a total annual output of only about 500,000 tons.
BB fertilizer is the direction of fertilizer development in the future. Its advantages are:
① Comprehensive nutrients, high concentration, significant increase in production and cost savings, and strong pertinence. Its total nutrients are generally above 52%. Currently, the effective ingredients of domestic compound fertilizers sold on the market are mostly about 25%, and the total nutrients of imported compound fertilizers are mostly 45%-48%. However, the nutrient proportion of imported compound fertilizers (N: P2O5:K2O=15:15:15) The phosphorus ratio is too high, resulting in a large waste of nutrients. The nutrient ratio of BB special fertilizer is proposed based on the characteristics of crop fertilizer requirements and the local soil nutrient supply situation. It is both scientific and targeted.
②Easy processing, low production cost and no pollution.
③The formula is flexible and can be flexibly changed according to different conditions such as crop nutrition, soil fertility and yield levels, which makes up for the fact that general-purpose compound fertilizers are prone to certain nutrient deficiencies or nutrient deficiencies due to fixed nutrient ratios. Disadvantages of excess. BB fertilizer can be used as base fertilizer or top dressing. Because of its good solubility, it should be applied on the surface as base fertilizer and should not be applied through the deep soil layer. When applying BB fertilizer to fruits, tea, vegetables, etc., it is not suitable to be broadcast. It should be applied in strips and holes, away from the seeds and The crop root system is 3 to 5 centimeters, cover with soil after application, and apply top dressing with water. The application amount per mu is only 60% of the imported compound fertilizer.
