    Soil Ph of Winthrop

    The definition of vegetation is plants considered collectively especially those found in a particular area or habitat. The amount of vegetation that occurs in soil depends on the type of habitat that the soil belongs to. Each habitat has inhibitors and prohibitions that affect the amount of vegetation that each plot of soil is capable of producing. Inhibitors of soil are plots that receive a decent amount of sunlight and precipitation; while prohibitors are soil erosion, temperature, lack of precipitation and P.H. Winthrop University’s research area is 325 acres; which includes a large wooded area, three successional plots, and 1.1 acre wetland area. The successional plots are 50 x 50 meters and each of the plots is five years apart in age. The oldest plot was originally created in 1989. In a previous study on the Chinese Loess Plateau to determine how physiochemical properties, microbial biomass, and enzyme activities changed the natural succession for abandoned farm land. The experiment involved aged and abandoned farmland from zero to fifty years old and the results were the PH was lower for the older farmland compared to the younger farmland.(Wang, Liu, Xue, Zhu, paragraph 1) Pertaining to the results of the past study, the objective of the study was to evaluate…

    Deforestation In Haiti

    • 649 Words
    • 3 Pages

    The first biophysical factor affecting soil is its topography, 75% of the land is mountainous with more than 60% of land with a gradient greater than 20%, even without human intervention, Haiti has a natural high risk of erosion. The second biophysical factor is its soil type. There are 4 major subtypes, Udepts and Usteps that are newly formed shallow soil that can support forests and grasslands. Fluvents that are shallow and sandy and so susceptible to leaching where the rate of soil erosion exceeds the rate of soil formation and Udults that are heavily leached acidic forests and has a very low fertility requiring additional nutrients to support successful crop production. Another factor is the bimodal rainfall pattern. Haiti has a tropical climate with two annual rainy seasons; April - June and August - November. These climatic conditions cause erosion by wind during periods of moisture deficit and by water during periods of moisture surplus. The differences in soil types means that there is a limited amount of cultivable land. Soil surveys by the US Department of Agriculture in 1980 state that only 11.3% of the land is suitable for crops, 31.7% is suitable for crops but with some restriction, 2.3% mediocre due to poor drainage system but acceptable for rice cultivation and 54.7% is suitable for tree crops or pastures due to severe erosion and steep…

    Soil Erosion

    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 are being lost each year due to gullies, and action needs to be taken. Gullies have altered the appearance of landscapes and lifestyles that civilians once enjoyed, forcing them to relocate elsewhere. Recent increases in the Nigerian population growth have further perpetuated the problem of gully formation as less land is suitable for farming and living (Hudec & al, 2005). As soil erosion occurs, the soil and nutrients are washed away and lost, creating channels or cuts in the ground, known as gullies (Ofomata, 1984). Weathering rocks are loosened by wind and rain, thus exposing the layers of soil formerly hidden under the ground. Soil erosion is a continuous process, and it is indeed very problematic, thus leading to the formation of gullies (Ofomata, 1984). The rate at which gullies are developing and expanding is definitely a cause for alarm. Gully expansion in southeast Nigeria has officially become an environmental hazard where a number of civilians have been forced to move somewhere else, and now more regions are becoming unsuitable for living (Adetona & Ezezika, 2011).…
