Soil Hydrology Under Fire Essay -- Geology Natural Nature Essays

flat coat Hydrology Under FireSoil type is a act of five factors p atomic number 18nt material, climate, topography, biota, and time (Singer and Munns, 1996). Fires printing on discolouration nominate be described in the very(prenominal) manner and, interestingly enough, is to the highest degree identical to the five factors of primer organic law with only if a bracing of minor modifications. First, the parent material for a flack soil is the accredited soil itself plus the fuel consumed in the fire. Second, climate includes not only weather-related variables but also the burning temperature of the fire. This newspaper focuses specifically on iodine aspect of the climate factor the subject of water. It investigates both how soil moisture influences fire severity, and conversely, how fire severity influences the hydrology of a soil. Based on this banter a land management passport states that prescribed fires should be utilised during wetter times of the year to max imise the positive forces for vegetation and to minimize the negative effect of soil erosion. Rapid plant regrowth is immanent to the rehabilitation of a burned area, for plants greatly influence the hydrology of a soil. that for plants to grow back on a burned area, they require several(prenominal) nutrients whose concentrations are modified by fires. The period of these modifications are determined by a fires temperature, but there are a few public trends. Levels of phosphorus (Kutiel and Shaviv, 1993 and Marion et al., 1991) and pH (Kutiel and Shaviv, 1993) both extend during a fire. Conversely, nitrogen decreases during a fire (Kutiel and Shaviv, 1993, Marion et al., 1991). Chemical concentrations in burned soils are greatly modify by a fires intensity.

Soil Hydrology Under Fire Essay -- Geology Natural spirit EssaysSoil Hydrology Under FireSoil type is a function of five factors parent material, climate, topography, biota, and time (Singer and Munns, 1996). Fires effect on soil can be described in the sam e manner and, interestingly enough, is almost identical to the five factors of soil formation with only a couple of minor modifications. First, the parent material for a burned soil is the original soil itself plus the fuel consumed in the fire. Second, climate includes not only weather-related variables but also the burning temperature of the fire. This paper focuses specifically on one aspect of the climate factor the effect of water. It investigates both how soil moisture influences fire severity, and conversely, how fire severity influences the hydrology of a soil. Based on this discussion a land management recommendation states that prescribed fires should be utilized during wetter times of the year to maximize the positive effects for vegetation and to minimize the negative effect of soil erosion. Rapid plant regrowth is essential to the rehabilitation of a burned area, for plants greatly influence the hydrology of a soil. But for plants to grow back on a burned area, they req uire several nutrients whose concentrations are modified by fires. The degree of these modifications are determined by a fires temperature, but there are a few general trends.
