Fertilizer Identification Methods
Fertilizers and raw materials for fertilizers must be identified by appropriate methods such as observation of their appearance, detection of active ingredients by qualitative tests, and confirmation with equipment. In order to ensure the quality of fertilizers, multiple methods are selected to identify substances accurately.
X-ray diffractometers (XRD) and Fourier Transform Infrared Spectrophotometers (FTIR) are introduced in the Fertilizer Identification Method developed by Food and Agricultural Materials Inspection Center (FAMIC) as methods for confirmation with equipment.
Appraisal method with FTIR
The figure below shows measurement data of an appraisal test for an Isobutylidenediurea condensed urea compound fertilizer using FTIR. Isobutylidenediurea condensed urea compound fertilizer is well known as a chemical fertilizer which is poorly soluble and has long-lasting effects due to relatively slow mineralizing hydrolysis and microbial decomposition.. Utilizing FTIR makes it very easy to confirm the identification of the standard fertilizer.

Dedicated IR pilot program ensures easy, instant system operation
To obtain the analytical data, IR Pilot Program was used for taking measurements and creating the report.
Operators with minimal FTIR experience can easily analyze samples by simply selecting the aim of the analysis and the optional parts to be used.
