What is the problem?
Investigates the effect of grazing on soil-water content to understand better this important indicator of rangeland health.
What did the research involve?
- Treatments simulated holistic planned grazing, rest-rotation and total rest at stocking rates of 36, 6, and 0 animal days/ha.
- Soil water content measured continuously from 2006 to 2008
What were the key findings?
- Grazing intensity varied from low (6 animal days ha−1) to high (36 animal days ha−1).
- Soil-water content (%VWC) was highest in the holistic planned grazing pasture (HPG).
- HPG used high intensity, short-duration grazing (6 days/year).
- Percent litter cover was also highest under the HPG treatment.
- Soil-water content varies in response to animal impact and the duration of grazing.
