As Bioeffektoren living are microorganisms and active ingredients from plants , plant residues and wastes referred to the growth, nutrient uptake and the resistance of crop plants against plant diseases and stress factors promote.

Areas of Effect

Bioeffectors are intended to increase the vitality of crops and thus their resistance to diseases, improve the utilization of nutrients in mineral fertilizers and make the nutrients bound in the soil more easily accessible to the crops . The aim is to reduce the use of agrochemicals and develop sustainable and environmentally friendly agricultural production.

According to the main effect, a distinction is made:


Research history

The investigation of bioeffectors and their effect on the utilization of fertilizers as well as the utilization of plant nutrients fixed in the soil goes back to the 1990s at the Institute for Plant Nutrition at the University of Hohenheim and is in the publications of Horst Marschner , Volker Römheld , Torsten Müller , Nicolaus by Wirén , Uwe Ludewig , Günter Neumann, Markus Weinmann and employees. Udo Glanz has developed a corresponding Massive Open Online Course (MOOC) for the education and training of schoolchildren and students .

International research project

In the seventh research framework program under the project name Biofector, the European Union is funding a corresponding research program of European and non-European research institutions, which are coordinated by scientists from the University of Hohenheim under the direction of Günter Neumann ( Institute for Crop Science ).

Research partners in this research project are:

Results and advice

The results of the investigations are u. a. evaluated by the members of the working group biostimulants in agriculture and made available to practice and the responsible bodies of the EU for the legislative and approval procedures.
