Seminar on plant nutrition in Tunisia

On April 30, 2018, Cotugrain Impex – our partner in Tunisia – held a seminar on optimal plant nutrition and express measurement methods.

300 professional visitors paid close attention to the very informative presentation of Harald Braungardt (CEO of STEP Systems) on soil parameters, their importance and effect on plant growth.

Another interesting presentation was shown by Dr. Yasser Dergham, Humintech GmbH, about the positiv effect of humic acid.
