Consequences of Non-Organic Farming – Assignment Example

The paper "Consequences Of Non-Organic Farming" is a wonderful example of an agriculture assignment.  Pesticides are used in nonorganic farming routinely to control weeds, pests, and diseases in crops The use of pesticides can hurt both air, land and water. Artificial fertilizers inhibit soil micro-organisms which actually help to prevent methane from escaping into the atmosphere. Nonorganic farming increases greenhouse emission gases and has a direct impact on causing global warming. Pesticide’s toxic run offs are washed away and get mixed with water. Causing the water pollution problem. This offers a threat to aquatic life and human being who consumes aquatic life and pose risk for downstream drinking water resources. Non-organic farming techniques use chemicals like pesticides and mono-crop methods which have led to the emergence of topsoil erosion

Consequences Of Non-Organic Farming (Topsoil Erosion):
Soil erosion is the process by which soil particles are detached from the soil surface and removed by the action of wind or water.
Soil erosion by water can be divided into a sheet, rill, and gully erosion
Sheet erosion is soil loss that occurs uniformly over an area of land and losses can be large.
Rill erosion occurs mainly after the potato harvest when fields are not protected by a cover crop or mulch during the winter. Significant rill erosion also occurs during the cropping season between potato drills during intense rainfall events.
Gully erosion is the removal of large amounts of soil from relatively small areas of natural surface depressions in the field.
Topsoil erosion is the removal of topsoil that is rich in crop nutrients and organic matter reduces the fertility of the soil which in turn affects food productivity
Topsoil erosion increases the harmful chemicals runoffs and offers significant challenges to life.
Soil micro-organisms are helpful to prevent soil erosion, but pesticides and fertilizers kill them. Soil stores carbon. The more carbon it stores, the less carbon dioxide there is in the atmosphere adding to global warming. Poor land management leads to carbon dioxide being released into the atmosphere from the soil.
Organic farming is better for the soil: Organic farming techniques help to build soil on an ongoing basis thereby preventing topsoil erosion and organic soil contains up to twice as many beneficial microbes, earthworms, and insects as non-organic soil. Organically managed soil has a higher quality and higher water retention. This may help increase yields for organic farms in drought years.
