Chemical Fertilizer Analysis Laboratory

In the fertilizer analysis and control laboratory, which has been in operation since the establishment of our Institute, chemical and physical analyzes of chemical fertilizers produced and imported in our country are carried out and their degree of compliance with the standards is determined.

Within the scope of chemical fertilizer analysis, the first accreditation was received from the Turkish Accreditation Agency (TÜRKAK) on June 17, 2010 according to TS EN ISO/IEC 17025 Standard. Our institution is the first laboratory within the Ministry to be accredited for N-P-K analysis of chemical fertilizers.

Chemical analyses include:
Accredited Analyzes:
​- Nitrogen (total nitrogen, nitrate nitrogen, ammonium nitrogen, urea nitrogen, biuret)
- Phosphorus (total phosphorus, water-soluble phosphorus, phosphorus soluble in neutral ammonium citrate)
- Potassium (water-soluble potassium)
- Total and water-soluble: iron, copper, zinc, manganese, magnesium, boron, calcium
- Determination of EDTA, HEDTA, DTPA in microelement fertilizers containing chelates according to TS EN 13368-1
- Moisture analysis, Sieve analysis
​- Ammonium, Nitrate, Urea Nitrogen
- Total (Ammonium+Nitrate) Nitrogen
- Total (Ammonium + Urea) Nitrogen
- Water Soluble Potassium
- Extractable Phosphorus
