AbstractThe effect of ploughing direction and method on the stem form of lodgepole pine was assessed in two replicated field experiments on low level blanket peat in Co. Mayo. Four ploughing directions were tested: NE/SW, E/W, SE/NW and S/N. Ploughing in the SE/NW direction, at right angles to the prevailing wind, produced three times the amount of stem lean as in the treatment ploughed parallel with the prevailing wind. Three ploughing methods were compared: open furrow ploughing at 1.83 and 3.66m spacing and tunnel ploughing. Tunnel ploughing, a form of subsurface drainage, resulted in significantly less sweep than the open furrow methods.
