Overgrazing is caused by having too many animals grazing on land or by not properly controlling the grazing activity of the animals. Overgrazing results in several negative consequences to both the land and the animals.Know More
Overgrazed land may see a loss of plant life. Cattle that graze on land often eat the younger seeds of plants, reducing the possibility for mature plant species to thrive. Soil is negatively affected as it loses depth, nutrients and eventually becomes eroded. Complete desertification may occur. Animals who depend upon land that is overgrazed suffer from nutrient deficiencies due to the fact the plant life on the land is no longer as robust. Animals may fail to gain weight appropriate to their life and production stage and may yield less of the product for which they are being raised.
Solutions to prevent and treat the effects of overgrazing include implementing fertilizers to augment soil nutrition and planting alternative grasses that help the land resist degradation. Controlling animals that graze is another step that can reduce overgrazing. Not allowing these animals to graze continuously is another solution. Reducing the overall herd numbers is also a solution, as is rotating the animals from one part of a pasture to another.Learn more about Agriculture
"Agriculture" is the cultivation of land for effective crop growth and raising of livestock. Farmers engage directly in agriculture by preparing soil, planting crops, harvesting those crops and preparing them for transportation. They also bale hay, grow pastures and buy seed to raise livestock.Full Answer >
Polyculture is the practice of growing multiple crops in one specific area of land, while monoculture means that an area of land only grows a single crop. A garden is an example of polyculture, and a cornfield is an example of monoculture.Full Answer >
While there is no set amount of land needed for a farm, M. D. Creekmore from The Survivalist Blog states that about 8,000 square feet is needed to provide a complete vegetarian diet for one person. This number assumes 100 percent crop yield and four growing seasons per year. Since an acre is 43,560 square feet, land in these conditions could sustain about five people per acre.Full Answer >
Sedentary farming is a method of agriculture in which the same land is farmed every year. This is in contrast to nomadic farming, in which new areas are farmed as the soil becomes less nutrient-rich from extensive planting, and shifting cultivation, which uses controlled forest fires to produce arable land.Full Answer >
