determine which location you choose to erect a fishpond includes water supply‚ the topography of the site and soil characteristics. In terms of water supply‚ the fishpond site must be situated in a location where there is constant water supply throughout the year and must be not less than three meters deep. It is important that the main water supply to the fishpond be safe and free from contamination. Contaminated water is the main cause of death in fish grown in fishponds. Keep the fishpond away from

Intensive farming is a way of producing vast amounts of crops by using numerous chemicals and machines. These practices include growing high-yield crops‚ using fertilisers‚ pesticides and keeping animals indoors. Food production is increased however there are various advantages and disadvantages of this particular method. An example of this method would be conventional chicken farming. This method may be used by farmers due to predators e.g. foxes killing their free range chickens‚ minimising their

Abstract: Soil serves as one of the basic medium of life as a variety of elements‚ which are vital to life are embedded in it. However‚ the human activities are polluting the soil unintentionally. Consequently‚ a wide range of contaminants enter the soil. Nevertheless‚ heavy metals are the most toxic of all the pollutants. Among these‚ lead‚ cadmium‚ chromium‚ mercury and arsenic are most toxic and can cause multiple organ damages even when present in small amount. Although‚ these elements are necessary

Soil is one of the main elements in the environment‚ it covers most of the dry part of the Earth’s crust‚ and the content of the materials‚ including salts‚ it is very important for the green vegetation cover on earth. On the other hand soil is one of the main components of construction‚ study of soil in the workplace is one of the first steps in the beginning of the project‚ and the lack of knowledge of soil characteristics and types and how to deal with it may lead to the failure of projects in

carbon dioxide (CO2) and contamination of water resources. It leads to loss of soil fertility due to imbalanced use of fertilizers that has adversely impacted agricultural productivity and causes soil degradation. Now there is a growing realization that the adoption of ecological and sustainable farming practices can only reverse the declining trend in the global productivity and environment protection (Aveyard 1988‚ Wani and Lee 1992‚ Wani et al. 1995). On one hand tropical soils are deficient in all

Anthropogenic hazards or human-made hazards can result in the form of a human-made disaster. In this case‚anthropogenic means threats having an element of human intent‚ negligence‚ or error; or involving a failure of a human-made system. This is as opposed to natural hazards that cause natural disasters. Either can result in huge losses of life and property as well as damage to peoples’ mental‚ physical and social well-being.

can exist on only if it is looked after and cared for. In the very first chapter Paton writes “the grass is rich and matted‚ you cannot see the soil. It holds the rain and the mist‚ and they seep into the ground‚ feeding the streams in every kloof. It is well tended and not too many cattle feed upon it; not too many fires burn it‚ laying bare the soil. Stand unshod upon it‚ for the ground is holy‚ being even as it came from the Creator” (33). This is significant because it is written in the beginning

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

Water Pollution Water pollution is the contamination of bodies of water such as ponds‚ lakes‚ oceans‚ rivers and even groundwater. Water pollution is mainly caused by many human activities‚ which can be harmful to animals and plants which live in these bodies of water are located. Nature also takes its toll on water pollution such as volcanoes‚ severe storms‚ and earthquakes also cause major changes in the quality of water. Water is typically considered to be polluted when it’s impaired

Soil is one of the most important natural resources of man. Soils are essential for man for growing crops‚ fodder and limber. Once the fertile portion of the earth’s surface is lost‚ it is very difficult to replace it. In India‚ the destruction of the top-soil has already reached an alarming proportion. Land degradation problems have resulted in increasing depletion of the productivity of the basic land stock through nutrient deficiencies. In addition to the direct loss of crop producing capacity
