![]() Like rotating crops, rotating pastures for grazing animals or livestock helps prevent overgrazing. ![]() Rotating crops also helps improve the health of the soil, and adding limestone helps add important minerals like Calcium (Ca) and increases the pH. In this strategy, farmers allow last year’s crop parts to decompose and help provide nutrients to the soil. ![]() ![]() This is a technique used in crop rotation.Ī way to improve the health of the soil and fertility is to add green manure. Strip farming is done when a series of long rows that are alternated with areas that are not planted. This practice helps reduce soil loss and erosion in hilly areas. If you see this type of farming from the air, it will look like a series of steps. Terracing is a farming practice used to cut out flat sections within hilly areas. For example, a farmer might plant legumes (such as beans or peas) in a field one year, followed by a cereal crop (such as wheat or oats) the next year. Traditional crop rotation involves planting a series of different crops in a field over a number of years, with each crop being chosen to add nutrients back to the soil that were depleted by the previous crop. Sometimes these rows of trees or bushes are planted on the outside of the farmland and are called hedgerows. This prevents wind from effectively eroding a lot of soil. Rows of trees or high-standing bushes are planted to prevent wind effects and block out direct impact. Windbreaks or shelterbelts is another strategy used for improving sustainable agriculture. Using this strategy, very little soil preparation or tilling is done and reduces the erosion from this type of farming. No-till agriculture is a type of farming that is used in soils that are dryer and have more sand. Contour plowing follows the natural contours of the land when plowing to reduce environmental impact since it follows land patterns, very little soil is disturbed. In terms of agriculture specifically, this means preventing soil erosion, as well as maintaining generally healthy habits. Contour farming is considered an active form of sustainable agriculture.To increase the sustainability of our planet, humans must work to regulate their usage/overuse of resources (both renewable and non-renewable) for future generations. Soil erosion prevention practices such as this can drastically decrease negative affects associated with soil erosion such as reduced crop productivity, worsened water quality, lower effective reservoir water levels, flooding, and habitat destruction. A similar practice is contour bunding where stones are placed around the contours of slopes. Tillage erosion is the soil movement and erosion caused by tilling a given plot of land. This method is also known for preventing tillage erosion. In contour ploughing, the ruts made by the plow run perpendicular rather than parallel to slopes, generally resulting in furrows that curve around the land and are level. The water break also allows more time for the water to settle into the soil. These contour lines create a water break which reduces the formation of rills and gullies during times of heavy water run-off which is a major cause of top soil loss and soil erosion.
