Dynamics of soil and how they impact on environment.

Rapid change of soil fertility, texture, water retention and its ability to absorb water has been the factors to determine the growth and development of plant species. But the only thing that affects plants rapid growth is that the soil could be lacking phosphorous. Phosphorous is nonrenewable source and its ability to penetrate and mix with the soil is slow.

Though the supply of phosphorous in the soil has been supplied by chemicals and animals waste, it has a negative impact on environment. Management of soil depends on the different routine activities that go on daily (Vavilor, 1979) for example, farming systems, mining activities and climatic changes.

Therefore the supply of phosphorus should be supplied having studied the soil and known the PH level, the fertility and the presents of soil organism which aerate the soil. Without these done the substance could be pumped into the soil causing environment pollution.

Change of weather and climate condition affects formation and the size of soil texture. In arid environment soil texture is course compared to wet and cold regions where the soil texture is fine. This contributes to the nature of vegetation available in the region.

The nature of soil available in a region determines the movement of human habitant, the reason why they settled plus their daily routine. It also affects the plants adapted to the region.

The entire society has a blame of not controlling soil destruction. Emissions from industries and wrong disposal of waste material contribute to it degradation which at some point it will penetrate to the soil. Also building construction accelerates soil erosion which covers water surfaces and disturbs water drainage.

One of the most important reason why the study of soil dynamics is to prevent environmental degradation. There are quite a number of factors that attribute to degradation (Dove, 1983; Weinstock 1983; Diemont and Martin, 2009). To begin with, poor methods of tillage and livestock keeping that contributes to soil erosion that sweeps out the top layer and leave bed rock layers with poor minerals balancing of soil nutrients.

Soil erosion has an advantage on flatter regions since it create a room for crop production but on the side it pollutes water areas and create problems on residential and movement on roads.

Proper management of soil has contributed to high sustenance of human habitat since it holds plant for production. It also act has home for micro-organism that has a role in soil fertility. Plants also help to maintain water level surface. Soil on the other hand provides materials for construction and mining.

Though human activities are dominating in destroying soil, they can also be the source of managing the soil and still benefit from it. They should be educated on ways of controlling soil erosion, farming practices that have less harm on the soil and micro-organism, proper ways of waste disposal especially on industrialization zones, building and construction to avoid soil erosion, proper drainage methods.

Finally, some use of chemicals on the process of improving soil fertility can act as build up for pests which destroy species of plants that act has vegetative cover of the soil. They also destroys micro-organisms by feeding on them that could have helped in soil aeration and facilitate easy decomposition process. Therefore soil is the basis for every living creature and it should be taken care off to avoid its destruction.
