Abstract

Seven tools including the TTS-35 disc trencher (model 2.4m), the Bräcke cultivator (two-row), the Leno-77 patch scarifier (modified), the Cazes and Heppner (C & H) front V-plow, the Angled dozer blade (model 8A), the Modified V-blade and the Fesco front V-plow (VP540), were comparatively tested in a residual poplar mixedwood stand in Saskatchewan. The three light skidder-drawn tools (TTS-35, Bräcke and Leno-77) achieved the highest numbers of plantable microsites in relation to prescribed spacing. However, the Leno-77 produced a higher density of microsites consisting of duff over a mineral soil base (plantable and marginally plantable). Scarification by the C & H and Fesco V-plows differed considerably from that by the wider Angled blade and Modified V-blade in terms of severity of the disturbance and final distribution of microsites. It is recommended that in residual poplar stands where high stand density precludes the use of light skidder-drawn equipment, front tractor mounted V-blades or plows capable of producing two rows of microsites be used to improve the efficiency and spacing of corridoring.
