Forest Soils on Acid Essay -- Ecology Nature Environmental Papers

tone vulgarisms on Acid plant ecosystems argon important both ecologically and economically. It is arguable that the most fundamental dynamic of the lumber ecosystem is the forest landed estate. The moroseness of forest soils can alter the chemistry, biota, and hydraulics of the soil, and thus, alter the soil physical composition characteristics and the soil composition. It fol abjects that the acidification of forest soils demands a great deal of research and attention. Forest soils are commonly found to have pH readings of 4-6, even in areas of moderate to low acid deposition (Binkley et al, p. 4). In fact, an abundance of forest vegetation thrives on and stabilizes most forest soils at relatively low pH levels. It seems as though forest ecosystems generally thrive upon strongly acid soils. Though forest soils naturally are acidic, problems can progress when the acidity levels are raised artificially through processes such as acid rain. This paper will investigate the effec ts of higher than recipe acidity and acid deposition in forest soils to gain a greater understanding of current and potential problems to forest soils and ecosystems. It is important to withdraw when discussing the implications of high acid in forest soils that there are several(prenominal) general factors that will alter acidic effects on soil chemistry, hydrology, biota, and weathering. These factors include soil figure, soil sensitivity, and the quantity of precipitation. Texture, structure, grain size, and consistence are all crucial to defining the soil type or serial and also to the amount of time soil is exposed to acid deposition. In a particular study on humus degradation ground on simulated acid rains conducted by Greszta et al. (1991) revealed the extent to which soil type influenced ... ...556-563. Mulder, J., J.J.
