Soil erosion is a major concern in the southeastern region of Nigeria due to high population densities and farming techniques‚ which has resulted in the presence of numerous gullies. While gullies are found all around the world‚ the existence of gullies in Nigeria is regarded as one of the worst environment disasters‚ having negative implications on the environment and the quality of life for humans and other species (Adetona & Ezezika‚ 2011; Ajaegwu & al‚ 2010). Large quantities of soil in Nigeria

Religious people should be more concerned about humans than endangered species Religious people should be more concerned about humans than endangered species Endangered species have more right not to be killed than members of other species‚ endangered species whose numbers are so small that the species is at risk of extinction. Once the endangered animals are gone they won’t come back. They are an important role in wildlife‚ if we take them out the whole system will be disrupted if some animals

Alkaline soil is referred to by some gardeners as”sweet soil”. The pH level of alkaline soil is above 7‚ and it usually contains a great deal of sodium‚calcium and magnesium. (1) Alkaline soil occurs in areas with high limestone content‚ easy souble phosphorus and calcium binding‚ formation of insouble calcium salts of phosphorus‚ reducing the effectiveness of phosphorus. Also‚ in calcareous soils‚ boron‚ manganese‚ molydenum‚ zinc‚ iron greatly reduces the effectiveness of the crop often feel inadequate

THE CONCEPT OF SPECIES What are species? Species are the basic taxonomic units of biological classification. This grouping of organisms of "like kind" into discrete and stable units has been traced at least from the time of Plato and Aristotle. The term derives from the Latin "specere" (to look at‚ to behold)‚ with the meaning of "kind‚“ "quality‚" "appearance‚" "shape‚" or "a peculiar sort.“ In the past‚ species were classified according to their shape. Carl Linnaeus (1707-1778)‚ the

1 Title: The Marine Biome #2 Biome Description and Definition The Marine Biome is made of all the oceans in the world. It holds many diverse species in animals and plants and since it is so enormous‚ there is some species that have not been discovered yet. The ocean is a mysterious thing because it is different in each part of the world‚ the climate depends on the location and the location depends on what species are located in that part. Australia is home to the coral reef‚ where today it is

Soil Mechanics Soil is the most misunderstood term in the field. The problem arises in the reasons for which different groups or professions study soils. Soil scientists are interested in soils as a medium for plant growth. So soil scientists focus on the organic rich part of the soils horizon and refer to the sediments below the weathered zone as parent material. Classification is based on physical‚ chemical‚ and biological properties that can be observed and measured. Soils engineers think

Kenneth R. Sagum May 7‚ 2013 FR1 NATSCI1 “Effects of Soil Erosion in the Philippines” The soil is among our most precious resources‚ yet we often take it for granted or destroy it by making it susceptible to soil erosion. In the Philippines‚ for example‚ 22 provinces had been reported to have "alarming" soil erosion rate. Among those that had been losing their topsoil were Cebu‚ Batangas‚ Marinduque‚ Ilocos Sur‚ and La Union. This means that 58 per cent of the country’s total
