Organic fertilizers can be divided into powder and granular forms, with some differences in use and performance:

1. Particle size: Powdered organic fertilizers have relatively small particles, usually in the form of powder, while granular organic fertilizers are formed by granulating the powder into granules. Granular organic fertilizers have relatively large particle sizes and regular shapes.

2. Application method: Powdered organic fertilizers are usually suitable for uniform distribution or spraying, and are usually applied manually. Granular organic fertilizers are more suitable for mechanical application, such as fertilizers, seeders, etc. The regular shape and larger particle size of granular organic fertilizers make them easier to control and quantify during the application process.

3. Application: Powdered organic fertilizers are suitable for small-scale application, mixing with soil before sowing, or use as base fertilizers. Granular organic fertilizers are suitable for large-scale application, mechanical fertilization, and long-term fertilization.

4. Nutrient release rate: Due to the small particle size and large surface area of powdered organic fertilizers, the nutrient release rate is faster, which can quickly supply the nutrients required by plants. Granular organic fertilizers, due to their large size, release nutrients relatively slowly and require gradual decomposition and transformation in the soil before being supplied to plants.

5. Storage and transportation: Powdered organic fertilizers are relatively sensitive during storage and transportation, and are prone to drift, moisture, or clumping. Granular organic fertilizers have good flowability and packaging stability due to their regular particle morphology, making them easier to store and transport.
