Fertilizer & Lime Analyses
The quality of bulk blends and liquid fertilizers are analysed in the laboratory. Sampling is deemed as important in this regard. NviroTek is one of the laboratories used by the ARC Potchefstroom, for the annual independent evaluation of fertilizers produced and used locally.
You are welcome to use the attached sample submission form. (sample attached)
