Synergia® Blue and Split – new in CALDENA’s offer

Microbial preparations are a response to climate change, the requirements of the European Green Deal, rising prices of mineral fertilizers, limitations in the number of available active substances as well as a decrease in the content of humus in soils.

To meet the challenges of the dynamic market and climate changes, we have complemented the CALDENA® portfolio with two biological products – Synergia® Blue and Synergia® Split, both of which are based on the synergy of nature and science. These preparations contain carefully selected strains of bacteria and fungi, which are subject to constant quality control. Synergia® Blue and Synergia® Split are compatible with most agrochemicals and have a long shelf life.
