Soil Analysis Introduction- The purpose of this investigation was to identify the texture of the soil we collected, while learning the different methods used to determine soil texture. I hypothesized the soil we collected from the North side of the school would be Clay Loam. In the Soil Introduction Power Point we learned about the pedosphere. We discovered that soil houses both organic (materials containing carbon compounds) and inorganic matter (materials like minerals: phosphates and nitrates)…

Land degradation will remain an important global issue for the 21st century because of its adverse impact on agronomic productivity, the environment, and its effect on food security and the quality of life. Productivity impacts of land degradation are due to a decline in land quality on site where degradation occurs (e.g. erosion) and off site where sediments are deposited. However, the on-site impacts of land degradation on productivity are easily masked due to use of additional inputs and adoption…

Introduction African soils are extremely poor by nature, they consist of low organic matter as well as all major nutrients. Sub-Saharan Africa does not produce enough food to support their countries even in years of good harvest. Land degradation is exhibited as deforestation, decreasing biodiversity resources, soil moisture stress as well as soil erosion. The following report will be assessing the socio-economic as well as the environmental impacts of soil erosion and land degradation impacts in the Ethopian…

Cultivation on Soil Condition in Funtua, Nigeria Mariya Labaran and Nasiru Medugu Idris Department of Geography, Faculty of Social Sciences, Nasarawa State University, Keffi, Nigeria Abstract This study involves the collection soil samples from six demarcated plots. Texture, pH, organic matter, total nitrogen, available phosphorus, exchangeable cations (EC), cation exchange capacity (CEC) and base saturation were assessed. Results show that the continuous cultivation of the soil and application…

Lagos, Nigeria Africa’s most populated nation has more than 150 million people and within this nation resides Lagos with a population of more than 20 million people. Lagos, Nigeria is the capital, nation’s biggest urban agglomeration, and is the third largest, most populated city in the world. Since early times, Lagos has grown through rural-urban migration. Lagos started off as a small farming and fishing settlement on an island close to the coast. In 1472 the Portuguese arrived on the land and…

Land degradation From Wikipedia, the free encyclopedia Serious land degradation in Nauru after the depletion of the phosphate cover through mining Land degradation is a concept in which the value of the biophysical environment is affected by one or more combination of human-induced processes acting upon the land.[1] It is viewed as any change or disturbance to the land perceived to be deleterious or undesirable.[2] Natural hazards are excluded as a cause, however human activities can indirectly…

The largest petroleum-producing nation in Africa is Nigeria. The petroleum company is the main contributing factor of the GDP in the West African nation, which is also the continents, most noticeable and populous reserves. Since Nigeria was under British control it has suffered socio-economic and political adversities for decades. Corrupt domestic militias and complicity of multinational corporations have rid the nation of its natural resources. The same corporations that are ridding the land and…

1.0 INTRODUCTION Soil degradation is a most serious environmental problem in many countries. One of the most important driving forces of soil degradation is human activities. Human activities often influence the natural processes in soil. According to(Doran et al., 1998; Cavelieret al., 1999; Chew, 2001; Liu et al., 2002; Johnson and Lewis, 2007; Seeger and Ries, 2008) defined deforestation as a perceptible aspect of human activities in environment. This change has many effects that can appear through…

Chapter 3 3.1 Introduction Land and soil degradation assessments have recently become more fashionable responding to environmental concerns particularly in industrial countries, following the lead in developing countries that have claimed significant effects of land degradation on their agricultural production and food security. The underlying causes of degradation have been very often the basic socio-economic structure and institutional structures of developing economies. Among them are land shortage…

The soil is a complex mixture of minerals, water, air, organisms and organic matter that are decaying remains of once-living things. The soil is vital in supporting plant life and all forms life. The soil is not consistent throughout the world because of the way that it is formed and environmental factors that vary through the process of soil formation. The factors that play the most important role in the formation of soil are climate, organisms, relief, parent material and time. These factors…
