Online learning platform of the ERASMUS+ project
Together with the Spanish association Asociación Agro-Cultura Con Respeto (Con Respeto), merckens development support is implementing the ERASMUS+ project.
The aim of the project is to provide training and exchange about experiences on organic and biodynamic agriculture to advisors and other actors along the agricultural value chain.
Within the framework of the project, training modules are being developed, which you can access on this platform.
This platform should also contribute to a lively exchange.
