Compliance with the highest norms, quality standards and international law.
Adherence to the “EC Fertilisers” definition ensures that our products satisfy all the requirements in the European Parliament Regulation no. 2003/2003 and its February 2017 amendment.

ADOB® quality

We believe that the quality of our products is ADOB®’s most important asset; therefore, we will never compromise it!

Our inhouse Quality Control Department consists of reliable, certified and highly-trained staff. It is equipped with the best analytical equipment, including:

  • An Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES)
  • High Performance Liquid Chromatographs (HPLC)
  • An atomic absorption spectrometer with a flame atomization (FAAS)
  • An atomic absorption spectrometer with electrothermal atomization in a graphite tube (GF-AAS)
  • Ion chromatographs (IC)
  • A spectrophotometer UV-VIS
  • pH- and conductivity meters
  • Moisture analysers
  • Granulometric sieves

ADOB® is very selective about the raw materials used in our production processes After all, only high-quality raw materials can be turned into high-quality products. Our raw materials are procured from Polish and foreign producers. We subject these materials to strict quality control in terms of their composition, moisture content, granulometric parameters, solubility and impurities.

Throughout the entire chemical and physical production process, various probes built into the reactors and containers automatically check and verify that the right conditions are maintained. These probes alert the staff in real time about any variation from the pre-set conditions.

Just before bagging the crystalline products, or pouring liquid fertilizers into canisters, a representative sample is analysed to verify that the products comply with our strict specifications, which follow the most up-to-date EU Regulation 2003/2003.

All cationic micronutrients in our fertilisers are 100% chelated. This is verified by determining the amounts of the chelating agents in each batch, in accordance with the PN-EN standard, along with the content of cations. The concentrations of the chelating agents and micronutrients are compared to ascertain that their concentration ratio always equals 1:1.

We also pay special attention to reducing the content of heavy metals to the absolute minimum possible. These tests are carried out using an atomic absorption spectrometer (AAS) equipped with a graphite furnace.
