Stool removal and land-use conversion

Stool removal is a two-step operation beginning with the spring application of a non-selective herbicide followed by the stool destruction in the fall using a light-duty forest stool grinder. SRWC varieties will normally produced a root system predominantly fibrous that is limited to a 3-foot radius in the soil profile, a physiological trait which facilitates the stool removal operation and enables a land-use conversion within two years of the last willow harvest. This characteristic explains why SRWC is not considered a reforestation of farmland. Consequently, in some jurisdictions like Quebec, willow planting does not require a ministerial authorization, nor does it lead to a loss of farmer status by prospective producers of the crop.
