October 20‚ 2014 1st Period Mr.MayesSoil Texture Lab Report Introduction Soil texture is one of the most important physical properties of soils. Soil texture is related to a number of important soil characteristics such as water holding capacity‚ soil drainage‚ and soil fertility. In order to make this lab work to our own convenience we will use soil from our nearby area. This project was conducted to specify what type of soil there is in the area and what it can be used for. Agriculturist may be able

INTRODUCTION Soil is the precious gift of nature to the mankind. All the plant family‚ animal kingdom and human society at large depend upon soil for their sustenance directly or indirectly. Ironically‚ soil is the most neglected commodity on the earth. Shifting cultivation on the hill slopes‚ non-adoption of soil conservation techniques‚ and over exploitation of land for crop production due to population stress‚ leads to enormous soil erosion. It will take hundreds of years to form an inch of soil‚ but

Tutor: Date: Foundation Engineering Soil exploration obtains information about the subsurface parameters and conditions at the proposed Soil exploration as part of site investigation. In general‚ it deals with determining the suitability of the site for proposed construction. This consists of determining the profile of the soil deposits at and near the site. It mainly consists of taking the soil samples and checking the engineering properties of the soil and testing it in Situ. It then gets to

Soil Erosion Erosion is a natural process by which rock and soil are broken loose from the earth’s surface at one location and moved to another. Soil erosion forms and changes land by wearing down mountains filling valleys‚ and making rivers appear and disappear. Erosion is usually a slow and gradual process that occurs over the course of thousands or millions of years. However the rate of erosion can be speeded up by such human activities as mining. How erosion occurs? Ero0sion begins with

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

Soil Pollution The process of contamination of the land surface of the earth is referred to as land pollution. It results from human activities that cause imbalance in nature. Dumping human and industrial waste harmful agricultural practices and exposing the land to harmful chemicals leads to the pollution of land. We speak of water and air pollution and rarely even think of the adverse effects of land pollution. Let me share with you some of the important facts about land pollution. Land

“Sons-of-the-Soil” and Local Insurgencies ABSTRACT One explanation for localized armed conflicts is competition between the original inhabitants of an area and more recent settlers‚ including both migrants from the same country and from abroad. As of yet‚ this explanation has not been thoroughly scrutinized‚ partly due to the lack of disaggregated data on violence needed to properly examine the hypothesis. Hence‚ this paper applies the idea of such “sons-of-the-soil” dynamics to

What is federation?Federation is a form of government in which powers and functions are divided between a central government and a number of political subdivisions that have a significant degree of political autonomy. It was the unification of Australian colonies which formed the commonwealth of Australia on 1st January 1901. ForBy the 1890 ’s nearly 75% of the population had been born in Australia. This created growing Australian nationalism. By the 1880 ’s the telegraph linked all capital cities

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
