We demonstrated the influence of mob grazing on 9 cooperating ranches throughout South Dakota. The study took place from 2012-2014. We sampled soils and vegetation at each site. Three graduate students evaluated the impact of mob grazing on the 1) function of litter, 2) impact of pasture weeds, and 3) the harvest efficiency and trampling of vegetation. We also collected animal behavior data using pedometers on mob grazing versus a low stock density weekly rotation. A fourth graduate student investigated the economics of mob grazing. The final report includes the soil data to determine impact on soil carbon and nitrogen of mob grazing.
1) Evaluate vegetation responses to mob grazing.
2) Evaluate animal behavior in mob grazing versus low stock density weekly rotation.
3) Evaluate soil carbon and nitrogen in mob grazed and rotational grazed sites.
4) Evaluate economic models for profitability analysis.
