Soil Microbiome Selection

Soil microbiome selection refers to the practice of cultivating and managing beneficial microbial communities in growing media to influence cannabis plant metabolism and secondary compound production. Breeders and cultivators working with living soil systems recognize that microbial diversity—including fungi, bacteria, and archaea—can affect terpene expression and plant phenotype. This approach differs from synthetic nutrient strategies and represents an ecological growing methodology. Research into cannabis-specific soil microbiology remains limited, though practitioners report observations of terpene profile variations correlating with microbial community composition. Understanding soil microbiome dynamics is relevant to breeding programs focused on consistent phenotype expression across generations.

Breeders interested in stabilizing terpene profiles or exploring phenotypic plasticity may evaluate how microbial inoculants affect offspring expression. Selecting parent plants grown in microbiome-rich environments may reveal genetic stability or variance under different soil conditions.
