// Definition
The use of hemp crops to clean contaminated soil by absorbing toxins and heavy metals through the plant's root system, a process that occurs whether farmers intend it or not when growing hemp.
// From the Episode
Discussed in context of Canadian Prairie hemp farming in Manitoba, Ontario, and Saskatchewan. The panel noted that every time a hemp crop is grown, nitrogen from leaves is recycled back into the soil, leaving it cleaner than before. Hemp farming in Canada had been ongoing for 20 years at that point, primarily for seed protein.
