BB Fertilizer Formulation Design: Three-Step Calculation Method and Particle Size Matching Key Points

Calculation Characteristics of BB Fertilizer Formulation Blended fertilizers (BB fertilizers) are made by directly mixing nitrogen, phosphorus, and potassium granules in a specific ratio without chemical granulation. Their formulation calculation is similar to that of compound fertilizers, but there are two significant differences: First, BB fertilizer raw materials retain their original particle shape, so nutrient loss during granulation does not need to be considered in the calculation; second, special attention must be paid to the matching of raw material particle sizes, as large differences in particle size can easily lead to stratification during transportation and packaging. Therefore, BB fertilizer formulation calculations must not only calculate the correct nutrients but also consider physical compatibility.
