A Study About Ido / Osi Local Government Area Of Ekiti State

By comparing the topography, soil moisture levels, relative humidity, and wind speed of the upland Savanna and Bottomland forest we will be able to compare and contrast between these two vegetation zones. The data collected in the investigation will be used to test the hypothesis that the bottomland forest has a higher degree of shrub layer cover than the savanna. The higher level of shrubs in the bottomland forest might be attributed to the space available for shrub layer species. In addition, the data collected will confirm that the bottomland forest has a higher tree density than the

The aim is to identify and associate landforms, rock types and soils to the natural environment and its plants and animals and also to investigate the history of the local environment, comprising human impacts over the last 50 years. The impact of human alterations to the environment includes increased soil erosion and changes in river flows.

“Drainage patterns, the hilliness of the ground, the range of soils, the nature of the bedrock,

Contain a distinctive top soil that is humose or peaty and a substratum starting at 40cm in depth which has been altered little (Avery, 1980; Buol, 1997). The soils do not contain a disturbed surface layer, the B horizon is not podzolic, weathered or argillic (Avery, 1980; Buol, 1997) and the soil profile is shallow (Ashman & Puri, 2002).

Extracted soil samples indicate simultaneous reduction of rainfall and occasional erosion. Both soil and sediment features show establishment of marked

The soil has a thick litter layer, but thin humus layers due to fast decomposition. There is also a rapid leaking, which is the downward movement of the nutrients in solution in the soil. Soil is determined by the climate, vegetation, topographic position and soil age.

This book is full of information about serpentine soil and the different habitats that can be formed form it. Some of the important information includes the fact that the deeper into the Earth we go the minerals forming its mantle and most of its oceanic crust, are darker and denser high-iron and -magnesium rocks and minerals. Which as they nearer the surface may have the ability to become “serpentinized”. The reason serpentine soils are so unique is because these rocks are rarely found on land, but occasionally get moved through the Earth due to subduction which brings up layers of serpentine rock to the surface causing these outcroppings of rocks. These layers, as described by the book, are truly “unearthly in their appearance”. Serpentine soils are deficient in plant essential nutrients and often also in organic matter which makes them really poor host for some forms of plant life. But because of their abundance of magnesium and sometimes in nickel, chromium, and cobalt it is a highly sought after habitat for mining. And also provides very lush surrounding soil areas. This book furthers the information that I’ve obtained for this project and probably has most of the more useful

In North America, sodic soils are mostly found in the northern Great Plains of the United States. Sodic soils develops on glacial deposits and till of saline shales (Heck and Mermut, 1992). The presence of a fluctuating water table, landscape position, topography, parent material permeability elevate the sodicity on glacial deposits (Wilding et al., 1963; Lewis and drew, 1973; Munn and Boehm, 1983; Seelig et al., 190; Richardson et al, 1992). The total area of North Dakota in the United States is about 18.4 million hectares and of these 1.9 million hectare area are considered as sodic and distributed across several parent materials (Web Soil Survey, 2013). Sodic soils are characterized by high sodium (Na) concentration in cation exchange complex. Which is about greater than 15% and defined as the soil with high sodium as compared to calcium and magnesium (Salcon, 1997, Soil Taxonomy, 1999). Sodic soil is one of the problematic soils which weaken the soil structure of the soils (Rengasamy and walters, 1994). So it is important to study these soil in detail by physical, chemical and micro morphological method and in relation to environment.

Cameroon is in central Africa, between Guinea and Nigeria, sometimes even called the “hinge of Africa” due to its volcanic activity. Its area in comparison to California is only slightly larger- about 475,000 sq km, which makes this a relatively small country. In terms of boundaries, it has about six countries that border it: the Central African Republic, Chad, the Republic of Congo, Equatorial Guinea, Gabon, and Nigeria. Its terrain is relatively plain, with its coastal plain in the southwest, the dissected plateau near the center, some high mountains westward, and north it has plains.

The soil moisture changed throughout the four sites, with the sites closer to the water naturally containing more moisture than those further away. Similarly, the pH levels of the soil were essentially all the same being around 7.5 (Figure 1.0). Queensland Governments states that soil classified between 6.5-7.5 is neutral (QLD, 2016). This could be because the soil gets an even balance of both alkaline and acidic particles and becomes neutral.

Analysis of representative soil samples will also be undertaken to characterise different soil material, for example, pH, particle size, organic matter, potential contaminants and so on.

Corruption, negligence and irresponsibility of the civil management have contributed to the continued spread of the slum in the city of Lagos.
