Root Associated Volatiles

Root-associated volatiles (RAVs) are organic compounds produced by cannabis root systems and their associated microbial communities, often detected in soil profiles and rhizosphere environments rather than in harvested flowers. These compounds emerge from plant-microbe interactions, including symbiotic relationships with mycorrhizal fungi and beneficial bacteria. While less commonly profiled than aerial plant volatiles, RAVs contribute to overall plant biochemistry and soil ecology. Research into RAV profiles remains limited compared to foliar terpene analysis, though breeders and soil scientists increasingly recognize their potential role in plant vigor and nutrient uptake. Detection typically requires specialized soil sampling and laboratory analysis rather than standard headspace methods used for flower aromatics.

Breeders working in regenerative and soil-health-focused cannabis cultivation are beginning to correlate RAV profiles with root vigor and disease resistance. Understanding RAV signatures may help identify cultivars better adapted to specific soil microbiomes and sustainable growing practices.
