There are significant differences in the production process and finished product characteristics between compound fertilizers and mixed fertilizers. Compound fertilizer is a process of mixing and granulating all nutrients in a factory so that each particle contains all the required nutrients, namely nitrogen, phosphorus, potassium and other trace elements, in a balanced manner. This means each pellet is consistent in nutritional content, density, shape and size.
In contrast, blended fertilizers are produced by mixing individual nutrients (such as pure nitrogen, phosphate and potassium) together into a specific product profile and then bagging them. The granules of fertilizer mixes vary in colour, shape and size, which means they can separate during mechanical application, resulting in uneven nutrient distribution.
Real compound fertilizer is completed in the production factory and has the following significant advantages:
Each particle in the compound fertilizer contains a balanced amount of nitrogen, phosphorus, potassium and sulfur, which ensures even distribution of nutrients when applied in the field. The particle sizes, colors and densities of mixed fertilizers vary. During the fertilization process, different nutrients may be separated due to gravity and wind, affecting the fertilization effect.
Because the compound fertilizer granules are carefully designed and mixed during the production process, the nutrients will not separate during transportation, storage and application. This ensures a consistent supply of nutrients when fertilizing the field.
The physical properties of fertilizer have a direct impact on its even distribution in the field. When a spreader applies fertilizer, the homogeneity of the fertilizer particles is directly related to the uniformity of nutrient distribution. Compound fertilizers are more evenly distributed in the field because of their consistent particle size and weight, while mixed fertilizers may cause uneven fertilization due to inconsistent particle size and density, which in turn affects crop growth.
Uniform application of nutrients is essential for crop growth. For example, when applying phosphate fertilizer in the spring, a compound fertilizer can provide more landing sites for the phosphate.
Once the spreader is accurately set, the uniformity of the compound fertilizer ensures that each particle is applied correctly without having to compromise on set-up.
High-quality compound fertilizers can achieve a wider application range and further improve fertilizer utilization and economic benefits.
In summary, due to its homogeneity and uniformity, compound fertilizer can better meet the requirements of modern agriculture for precise fertilization and improve the growth quality and yield of crops. It is an important innovation in the field of agrochemicals.
