The Effects of Grazing and Trampling Behaviors of Large-Sized Livestock on the Formation and Weathering Patterns of Soils

Introduction of the impact of grazing and trampling on large-scale domestic animals on soil formation and weathering patterns Walter Koppinger is a professor of earth science at Trinity College in San Antonio, a longtime observer of Montana's geology, a cow It is the first production by overgrazing. Many problems on the Western pasture From the upper belly of the highland high hill of Whitehall, Montana, he pointed out several ways on the horizon and the way through pasture pastures.

Many animal breeders question the importance of greenhouse gas pollution due to land degradation and livestock grazing. They often say that Alan Savory can be controlled by catastrophic effects of livestock on soil and climate by "overall management and planned grazing." The Savory process is said to have made it possible for domestic herds to work as 'pre-herd and carnivore proxies', trampled hay and leave 'feces, urine and garbage or covering'. This is said to allow the soil to "absorb and control rain water, store the carbon and decompose methane".

The impact of grazing on the environment may be positive or negative depending on the quality of management, grazing may have various effects on various soils and various plant communities. Grazing occasionally reduces the biodiversity of grassland ecosystems and sometimes increases them. Studies comparing several grazing in the US and the original grassland under non-domestic management system showed that soil organic carbon content is slightly lower, but soil nitrogen content at grazing is higher. In contrast, at the Plateau Prairie Research Station in Wyoming State, the upper 30 cm soil of pasture grassland contains more organic carbon and nitrogen than grassland without livestock. Similarly, in previously eroded soils in the US Piedmont area, grazing of well-established and controlled livestock has resulted in carbon and nitrogen isolation rates against the growth of grassland without grazing.

In this paper, it is impossible to judge the influence of interference (for example biomass damage due to trampling) or excessive compensatory plant growth from the Sahara desert, so "NPP in natural, non-degraded grassland" is low to moderate Assume that it is not affected by grazing pressure. Evidence from South Africa suggests that introducing livestock into the natural grassland of a large herbivorous population decreases the capacity of natural herbivores to lead to feces. "But the newspaper added that this agnosticism" will not apply to artificial pastures or devastated land. "
