Water soluble fertilizer.

FER EXPO is a fertilizer specially developed to provide crops with the three main macro-elements: Nitrogen, Phosphorus and Potassium.

Its application is recommended when there are difficulties in assimilating conventional fertilizers, either due to the low activity in the clay-humic complex or due to the use of saline waters whose conductivity prevents the contribution of conventional fertilizers.
