Fertilizer Physical Properties & Performance Testing

Fertilizer Testing Services to Improve Product Performance

Checking fertilizer performance after development requires more than just testing whether the correct balance of nutrients are present and available. The fertilizer must also avoid problems with storage, handling, and transport. These problems may occur as caking, segregation, dustiness, or absorption of moisture. For successful product development, a full range of testing is required. Applied Chemical Technology has years of experience in testing the physical properties as well as the controlled release characteristics of fertilizer in the laboratory, greenhouse, and field.
