Soil, the Threats That the Term Paper

These human actions that alter the living and nutrient conditions of soil organism include the repetitive tillage or burning of vegetation, soil erosion, overusing the land without replenishing it with humus or plant compost, clearing of forests. What can be done to solve this problem is to replenish the land with humus or plant compost, give the land rest after excessive use, planting of trees to reduce soil erosion etc. The soil organic matter is linked to the atmosphere; hydrosphere, biosphere and climate change in that the carbon cycle is the biogeochemical cycle by which carbon is exchanged among the hydrosphere, biosphere and atmosphere of the earth.

The following are the strategy that I feel should be taken to restore the regions of Udaipur in India. In this area it is evident that the unnecessary human activities of over grazing, slash and burn farming, and activities causing soil erosion have affected the soil quality. To improve there are various strategies that need to be adopted. Conservation agriculture is an alternative to slash and burn crop production methods that have been adopted in this place. This will generally involve alternating land between crops production, and native vegetation and forests. 'During crop production without fertilizer additions and good soil management practices, soil quality and crop yields decline overtime, when this happens the field should be left for some time to rest and re-growth of native plants will restore soil quality over time.' (Curry and Good, 1992). Once the soil quality is restored, the native vegetation can be cut and burned to release nutrients back to the soil.

The strategy works well and the natives of Udaipur in India should give the land ample time to replenish and for native vegetation re-growth, typically for some years. It would be ideal if they maintained year round soil cover, with residues from previous crops or a crop cover, minimizing soil disturbance by tilling and rotating crops to improve soil health and quality.It would be also be advisable if they planted more trees to stop soil erosion either by water or wind and given this is a remote grassland region.

Marsha vision was on a landscape lost to the human induced activities of the 20th century. Marsha dreamt of when this will change, that is the landscape and its transformation by human action. Natural landscapes in this case simply mean environments that have not been altered by human action. Cultures landscapes on the other hand have been altered by people through things like building of structures such as campsite.

Human actions have been altering landscape and thus diverting water bodies' flow, water diversions, and connections between wetlands, diversity of habitats combined with agricultural and urban development, thus altering the landscape and causing a lot of damage to it as a result. If one is planning a new landscape or construction it is good to consider how your project will affect the natural resources. It is good to know how you will be disturbing soil, and how you will contain it during rain storm. This is what Marsha had observed and it was his dream that things would change with human actions taking care of the landscape instead of disturbing it.

It is good to know how your construction will interfere or affect trees. It is also ideal to be considerate of any wetlands, creek or lake nearby. Minimize tree impacts within the critical root to prevent tree loss, install a silt fence, cover exposed stock piles, steep slopes etc.

Conclusion

Soil is a very important resource in the earth and care should be taken to preserve and maintain its quality. If this is not done, soil will not be able to support the future generations and this means they will be low food production in the world leading to famine to both human beings and animals
