Soil conservation includes all such measures which protect the soil from erosion and restore its fertility. These measures are of two types-(a) small measures to check soil erosion at local or even individual level‚ and (b) large measures at government level involving larger area and heavy investment. (a) Small Measures-These include afforestation‚ regularised land strip cultivation or contour farming or terrace farming in hilly areas‚ use of stubble mulch system‚ increasing cohesiveness of the

Temperate forests correspond to forest concentrations formed in the northern and southern hemisphere‚ or in temperate regions. Main characteristics include: wide leaves‚ large and tall trees and non seasonal vegetation. Temperate forests can be further distinguished by weatherpatterns and geographical features that favor the predominance of certain kinds of trees. In temperate coniferous forests‚ evergreen coniferspredominate‚ while in temperate broadleaf and mixed forests‚ a more even distribution

Soil is an important natural resource that covers much of the earth’s land surface. All life on earth depends on the soil as a direct or indirect source of food. Plants are rooted in the soil and obtain nutrients (nourishing substances) from it. Animals get nutrients from plants or from animals that eat plants. Certain microbes in the soil cause dead organisms to decay‚ which helps return nutrients to the soil. In addition‚ many kinds of animals find shelter in the soil. Soil contains mineral

What Is Soil Pollution? Soil pollution comprises the toxic waste of soils with resources‚ mostly chemicals that are out of place or are present at concentrations advanced than normal which may have unpleasant effects on humans or other organisms. However‚ soil pollution is also caused by resources other than the undeviating addition of man-made chemicals such as undeveloped runoff waters‚ industrial waste materials‚ acidic precipitates‚ and radioactive clash. Both organic and inorganic contaminants

Soil‚ which is one of the most important natural resources‚ is often less heeded. The importance of soil conservation is relatively less talked about as compared to the conservation of water and other natural resources. The almost-omnipresent soil is mostly taken for granted. Its omnipresence is ironically the reason behind us‚ human beings‚ taking it for a ride. We rarely even think of it as a natural resource that needs to be conserved‚ a part of the natural wealth that needs to be preserved.

Beach erosion longstanding challenge for southeastern NC There is a major environmental concern in the southeastern region North Carolina; it is beach erosion. However do not worry‚ the article states “The good news is that we do have alternatives to help control erosion‚ but the bad news is that these alternatives can also have negative consequences.”. A method that is able to help control erosion is beach nourishment‚ although it is not a cure for beach erosion‚ but rather a treatment to help

Soil Salinity Salinity in both the rivers and on the land is one of the main and most costly results of overclearing and irrigation. Salinity is caused by changes in the delicate balance between surface water and groundwater systems. A small increase in the infiltration of water from the topsoil to the groundwater‚ due to rainfall or irrigation‚ can result in a dramatic rise in groundwater pressure and watertable levels. The trees of the open forests are now replaced by shallow-rooted crops and

How has erosion effect beaches in recent times? In recent decades erosion has become a major issue to beaches around Australia‚ since beaches are temporary features. There is always sand being removed and sand being added to them‚ often‚ they change drastically during the year‚ depending upon the frequency of storms. Eventually‚ a beach erodes because the supply of sand to the beach cannot keep up with the loss of sand to the sea. The Sand dunes and vegetation help to hold the sand in place when

IMPORTANCE OF FORESTS Introduction Trees are mankind lifeline. If they are destroyed‚ there is no way that human beings can survive. From the oxygen that we breathe in‚ the food that we eat‚ to the clothes we wear‚ we owe it all to the trees. Not only this‚ trees act as purifiers of air and receptacles of our waste products. Trees have great economic value too. We get fuel‚ fodder‚ timber‚ medicines and numerous other valuable products from the trees. It is‚ therefore‚ not surprising that trees
