Fertilizer Physical Properties & Performance Testing

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 controlled release characteristics of the performance of the fertilizer in the laboratory, greenhouse, and field.
