SOIL EROSION AND CONSERVATION

Selected Region: Rural Areas.
Intensive agriculture heavily relies on the quality of soil, the availability of resources
such as water and the use of artificial fertilizers to ensure that farmers achieve high crop yields.
The application and manufacture of fertilizers disrupt nutrient cycles thus creating the
unbalancing of the natural ecosystems around various agricultural areas, particularly because the
earth has a limited quantity of chemical elements. The article thus centers on explaining the main
biogeochemical processes and how specific chemicals and nutrients depleted through erosion as
well as the control techniques applicable.
Nitrogen and Phosphorous Cycles.
Soil cycles are subject to disruption while the earth`s chemicals such as phosphorous and
nitrogen function in a closed system where they always recycled throughout geological and
biological cycles. Phosphorus exists in various compounds in the earth surface such as the
phosphate ion which found in sediments, water, and soil, (Blaikie, P). Phosphorous quantities in
the ground are limited and thus limit the extent of plant growth which is why phosphorous
amounts increased through the use of fertilizers. Phosphorous moves in a cycle through
sediments, soils, water, organisms, and rocks.
Weathering and rain cause rocks to release minerals such as phosphate ions that then
distributed in the water and soil. The plants then take up the inorganic phosphate from the
ground. When the plant consumed by an animal and then released during decaying of the
organism, the phosphate retur...
