the world due to salinity‚ as when the salt gets on to the top of the soil.....it causes disaster to the plants and trees. Salt comes in many forms in the natural environment—calcium‚ magnesium‚ carbonate‚ sodium chloride‚ bicarbonate‚ and sulphate. Many landscapes are naturally saline‚ but secondary salinity isn’t so natural‚ occurring when salts from deep within the earth are dissolved and deposited into soil and water as a result of human activity. This can happen in one of two

and consequently as led to the deterioration of this essential component of the biophysical environment. Land degradation has become one of the primary issues of concern arising from the human interaction with the lithosphere. It encompasses soil degradation and the deterioration of natural landscapes and vegetation. It includes the adverse effects of overgrazing‚ excessive tillage‚ erosion‚ sediment deposition‚ extractive industries‚ urbanisation‚ disposal of industrial wastes‚ decline of

Sometimes the ground can seem like its rich in top soil but it can be sand or clay. The spot that you choose also needs good drainage. Vegetables will not grow on poorly drained soil‚ even if you use the best fertilizer money can buy. The next step to have a successful garden is making the rows. This way your

Conservation Make a Difference” Living in a country with rapidly growing population‚ conservation is an increasingly pressing matter. This dilemma is more prevalent in times of drought. Individuals have to play a part to manage water and to keep from soil erosion. However‚ making a population do something is a difficult objective to achieve. I offer a solution in three ways: one‚ that a fine is imposed on citizens that go over a certain amount and two‚ we make appliances and water efficient farming

which causes the color to change from black to gray. Oil‚ gas‚ and rain seep into the asphalt and hasten the development of cracks and potholes. Cracks are more than an eyesore. They allow rain to drain into the soil beneath the asphalt layer‚ and this causes the soil to shift. The shifting soil causes the cracks to get bigger‚ and it can even cause the underlying base of your driveway to become unstable. Having

The waste of an open dump would decay and form part of the soil as organic manure. • Land Filling A landfill site (also known as tip‚ dump‚ rubbish dump or dumping ground and historically as a midden) is a site for the disposal of waste materials by burial and is the oldest form of waste treatment.

Another way farmers are going to conserve is by growing high residue crops. In other words‚ if they leave dried out corn or other crops‚ it will cover the soil and create residue. Lastly‚ farmers can capture more rainfall by trying not to pump from the aquifer unless needed. In addition‚ if the attempt fails

Red soils develop in a warm‚ temperate‚ wet climate under deciduous forests and have thin organic and mineral layers overlying a yellowish-brown leached layer resting on red layer made of iron oxide(ferric oxide). Red soils generally form from iron-rich sediments. They are usually poor growing soils‚ low in nutrients and humus and difficult to cultivate. These soils are developed on old crystalline rocks under moderate to heavy rainfall conditions. They are deficient in phosphoric acid‚ organic matter

Deltamethrin is the most commonly used pyrethroid in agricultural practices commonly used in different geographical parts of the world. It is detected in many environmental areas such as soil and water‚ posing a toxic effect on humans and other organisms.
