This 2-year study investigated the effects of winter brassica forage crop grazing treatments on soil physical properties on a Fragic Pallic soil, susceptible to compaction, in South Otago, New Zealand. Soil physical measurements including bulk density, percentage of pores >300 [micro]m, macroporosity (air-filled porosity; percentage of pores >30 [micro]m), total porosity, air permeability, and saturated hydraulic conductivity ([K.sub.sat]) were taken 1.5 and 4 months after completion of winter grazing in year 1, and 2.5 months after grazing in year 2. Treatment main effects in year 1 for macroporosity were ungrazed crop (P
