The untreated control plot tested at 12.30% Total CBD and 15.61% Total Cannabinoids, with Δ9 THC at 0.03%, Total THC at 0.53%, and moisture content of 71.0% at harvest. The control plot established the baseline cannabinoid profile under the existing production program, with no microbial inoculant added beyond the standard fertility regime. Cannabinoid percentages at this level reflect typical Southeast hemp production but leave room for improvement in per-pound crop value driven by CBD and total cannabinoid content.

The Sunrise-treated plot tested at 15.40% Total CBD, a 25.2% increase over the control, and 19.60% Total Cannabinoids, a 25.6% increase. Moisture at harvest measured 69.2%, slightly lower than control and favorable for post-harvest drying and storage. Δ9 THC measured 0.03%, identical to the control, while Total THC measured 0.69%. The trial demonstrated meaningfully higher CBD and total cannabinoid content in the Sunrise-treated hemp with no increase in measured Δ9 THC, important for commercial growers operating under federal compliance thresholds. For licensed CBD hemp producers, certified organic operations, and Southeast farms looking to lift cannabinoid content without disrupting their existing fertility program or compliance profile, this trial demonstrates what an OMRI Listed multi-strain soil probiotic like Sunrise can deliver under real production conditions.
