What’s interesting about this is while the study focuses on trees, there are broader implications. Climate change and changing soil conditions will cause microbial environments to change. As a result, favorable conditions for plants will change, and thus the plants will follow the microbes around.
For any outdoor growers, this is particularly important. Keeping an eye on your soil’s health is not just about your NPK, but the microbes themselves (as many of us are aware).
This also has implications on wild types of cannabis as well. Where they can be found and their genetics may change based on these changing soil conditions too. Ruderalis, for example, will likely start to travel northward.
