| Abstract | The International Fertilizer Development Center (IFDC) has prepared a 3rd edition manual outlining methods for determining fertilizer's physical properties, including procedures used by IFDC to evaluate the physical quality of commercial and experimental fertilizer products and raw materials. Many of the procedures included in the manual were adopted from the Tennessee Valley Authority (TVA) National Fertilizer and Environmental Research Center (formerly National Fertilizer Development Center) and other organizations involved in measuring physical properties. IFDC does not endorse these methods as being standards. This revised manual includes IFDC procedures related to the following physical properties of fertilizers: critical relative humidity, moisture absorption-penetration characteristics, flowability, chemical compatibility in blends, caking tendency, size analysis, physical compatibility in blends, angle of repose, bulk density, apparent density, true density of solids and liquids, viscosity, granule crushing strength, abrasion resistance, impact resistance, handling strength, sphericity, conditioner adherence, dustiness, surface area, disintegration rate, and porosity. Additionally, IFDC has included six procedures that have been given the status of international standards by the International Organization for Standardization (ISO). | |
