explain over grazing of animals in land degradation
Answers
ANSWER -
Overgrazing removes the vegetal cover over the soil and the exposed soil gets compacted due to which the operative soil depth declines. So the roots cannot go much deep into the soil and adequate soil moisture is not available.
Hope it helps you..!!
Explanation:
Their loss is critical in determining the soil's water-holding capacity and how well pasture plants do during dry weather. Overgrazing results in increased trampling of soil by livestock, which increases soil compaction (Fuls, 1992) and thus, decreases the permeability of the soil.
effect of over grazing?
Overgrazing leads to soil compaction, decreased water retention, increased salinity, and loss of some nutrients, particularly nitrogen. Our results also suggest a strong influence of overgrazing and its associated changes in vegetation condition on the soil ability to buffer water stress during the dry season.
How can we solve overgrazing?
1)To prevent overgrazing, the following steps can be taken:
2)Pasture forage can be supplemented with stored livestock feed.
Livestock can be pulled off pasture.
3)A percentage of pasture acres can be planted for warm- or cool-season species while perennial-species recover.
