Analysis of growing media

Downloads
Changed on: 02.01.2017

The analysis of growing media provides information about the quality of the substrate before starting the cultivation as well as the possibility of investigating problems during cultivation.
In our accredited laboratory we use methods according to Austrian, CEN and ISO – standards.

We offer the following analyses:

  • Determination of laboratory bulk density (fresh matter, dry matter)
  • Determination of pH
  • Determination of salt content
  • Determination of Carbonate content
  • Determination of mineral nitrogen (NO3 and NH4)
  • Determination of “plant available” P, K, Mg, Fe, Mn, Zn, Cu, B according to ÖNORM S 2021
  • Determination of “plant available” P, K, Mg, Fe, Mn, Zn, Cu, B using CAT-extraction
  • Plant response test

Based on the results, the corresponding interpretation can be provided.
