Soil /Fertiliser analysis

The determination of trace elements and nutrients in soil is important to optimise the plant growth. For this issue filter papers with very low content of minerals is essential to get reliable analysis results. The average ash content of our quantitative papers is 0,004%, and 0,002% ash of the hardened quantitative papers - the purest paper in the filter market.

 

Target User:

  • Farmers
  • Independent institutes and governmental control labs for agriculture

 

Target Application:


Analysis of nutrients, mineral nutrients, contaminants and microbiological quality.

Ideal for the detection of trace elements like Mg, Mn, Zn, Co, Cu, Mo, and B.
