Composts are as diverse as their input materials and their production methods. Integrated in agricultural production, composts can initiate a variety of beneficial processes. On the other hand, poor compost qualities can also import potentially toxic substances into soils.
The following parameters are part of the analysis:
Basic parameters: pHWater, pHKCl, electrical conductivity (EC), lime content, content of organic matter, C/N-ratio, Nt, wet density
Water-soluble substances (nutrients, trace elements, pot. toxic substances): Ca, Mg, K, Na, NH4-N, NO3-N, Al, Ba, P, Si, SO4, Cl, Fe, Mn, Cu, Zn, Co, Mo, B, As, Ni, Cr, Pb, Cd, Tl, V
“Total Contents” in agua regia (nutrients, trace elements, pot. toxic substances): Ca, Mg, K, Na, Al, Ba, P, Fe, Mn, Cu, Zn, Co, Mo, B, As, Ni, Cr, Pb, Cd, Tl, V.
A representative composite sample should be taken. If it is necessary to assess the samples regarding legal requirements, it is mandatory that certified service providers take the sample.
