The way people use land can affect the levels of nutrients and pollution in soil.
However, farming has some harmful effects and can lead to soil loss.
Farmers often add nutrients to soil in the form of organic or artificial fertilizers to make their crops grow better.
How is soil affected by vegetation?
Landscape, Vegetation and Organisms. Vegetation plays an important part in the formation of soils from solid rock. The acids released by the roots of some plants act to breakdown the rock on which the soil is forming. The vegetation on a soil is particularly important in supplying the soil with precious organic matter.
How is soil important to agriculture?
Soil is a critical part of successful agriculture and is the original source of the nutrients that we use to grow crops. The nutrients move from the soil into plants that we eat like tomatoes. Nutrients are also a part of the food animals (like cows) eat. This allowed farmers to use the same soils for a very long time.
How does agriculture degrade soil?
Increased demand for agriculture commodities generates incentives to convert forests and grasslands to farm fields and pastures. Sustainable land use can help to reduce the impacts of agriculture and livestock, preventing soil degradation and erosion and the loss of valuable land to desertification.
