If an area is allowed to be overgrazed, the vegetation is repeatedly being trampled and the native plants will be unable to grow and start dying. Additionally, after the ground has been walked on repeatedly by large livestock, it becomes more firm and compacted, making it harder for the native vegetation to grow.
To stop overgrazing, producers must move livestock out of a pasture before regrowth begins. During periods of fast growth, overgrazing will occur if livestock are kept in a paddock for more than three or four days. Equally important, we need to make sure we don’t bring the animals back before plants have recovered.
Overgrazing can be defined as the practice of grazing too many livestock for too long a period on land unable to recover its vegetation, or of grazing ruminants on land not suitable for grazing as a result of certain physical parameters such as its slope. Overgrazing exceeds the carrying capacity of a pasture.
Overgrazing can reduce ground cover, enabling erosion and compaction of the land by wind and rain.. This reduces the ability for plants to grow and water to penetrate, which harms soil microbes and results in serious erosion of the land.
Due to overgrazing by cattle, the cover of vegetation almost gets removed from the land. The soil becomes exposed and gets eroded by the action of strong wind, rainfall etc. When the grasses are removed, the soil becomes loose and susceptible to the action of wind and water.
Answer. Answer: Crop Rotation: Rotating in high-residue crops — such as corn, hay, and small grain — can reduce erosion as the layer of residue protects topsoil from being carried away by wind and water. Conservation Tillage: Conventional tillage produces a smooth surface that leaves soil vulnerable to erosion.
Overgrazing by cattle reduces plant cover, eliminating the most desirable forage species first. This opens up the land to undesirable weeds, brush, and trees and leads to increasing soil erosion and lower soil fertility. The land becomes less and less productive.
Soil erosion is a naturally occurring process that affects all landforms. In agriculture, soil erosion refers to the wearing away of a field’s topsoil by the natural physical forces of water (Figure 1) and wind (Figure 2) or through forces associated with farming activities such as tillage.
Liquid water is the major agent of erosion on Earth. Rain, rivers, floods, lakes, and the ocean carry away bits of soil and sand and slowly wash away the sediment. Rainfall produces four types of soil erosion: splash erosion, sheet erosion, rill erosion, and gully erosion.
Soil Erosion is the process that erodes, breaks or gradually diminishes things down. The process of erosion usually takes place on the surface of soil, rock, or dissolved material from one location on the Earth’s crust and with the help of the wind or water flow, it gets to settle down at another location.
