Naeth et al. measured soil bulk density, moisture and penetration resistance in three Alberta plant communities, grazed at different intensities and times of the year. The impacts of grazing on soils varied by plant community, however in general, heavy or severe grazing and early season grazing were the most detrimental to soils. The combination of trampling and defoliation increased soil bulk density and penetration resistance, whereas defoliation alone did not affect soil characteristics. Based on these results the authors concluded that light to moderate grazing intensities under season long or late season grazing will maintain soil properties and plant growth in most Alberta pastures.
