Soil Microbiome

The soil microbiome refers to the complex community of bacteria, fungi, protozoa, and other microorganisms living in growing media and cultivation substrates. In cannabis cultivation, soil microbiota play a functional role in nutrient cycling, organic matter decomposition, and root colonization dynamics. Breeders and cultivators often study how different plant genetics interact with microbial communities, as root architecture and exudate profiles can influence microbial recruitment and diversity. Understanding soil microbiome composition has become relevant to cultivation methodology research, particularly in regenerative and organic growing systems. This field intersects plant genetics, soil science, and microbiology rather than describing a single trait or lineage.

While not a heritable trait in itself, breeders increasingly document how plant root systems and metabolite production influence microbial colonization patterns. Studying these interactions helps identify cultivars suited to specific growing substrates and microbial communities.
