Higher yields with soil microbes than with fertilisers

A new study of the Swiss Research Institute for Biological Cultivation (FiBL) and the University of Basel shows that soil microbes can increase yields significantly and much less fertilisers are needed.

This is the result of a global meta-study. In general, the use of microbes to increase yields is most promising in dry areas, such as the Mediterranean region or dry tropical regions (e.g. parts of India and Africa). In these climatic areas, the highest yield increase was achieved.

The efficiency decreases with an enhanced content of humus in the soil, which is linked to a larger population of soil microorganisms. This makes it more difficult for newly introduced microorganisms to establish themselves. But humus also means higher yields through the microorganisms present and the better water management.
