It has been known for some time that the ratio of fungi to bacteria varies in different types of soil and in different plant communities. Forests have a higher ratio of fungi while grassland and agricultural soil is higher in bacteria. This has led to the idea that plants grow best when the fungal to bacterial ratio is matched to their needs. Gardeners should not only monitor their fungi to bacteria ratio, but also modify the soil to change it.
In this post I will look at the science support this idea.
