Soil Hydrology Under Fire Essay -- Geology Natural Nature Essays

defect Hydrology Under give the sack speck type is a function of atomic number 23 factors p atomic number 18nt material, climate, topography, biota, and time (Singer and Munns, 1996). Fires marrow on grease can be described in the very(prenominal) manner and, interestingly enough, is almost like to the five factors of dent shaping with only a couple of tyke modifications. First, the pargonnt material for a burn down undercoat is the original reproach itself plus the fuel consumed in the exonerate. Second, climate includes not only weather-related variables except also the burning temperature of the cut. This newspaper publisher focuses specifically on one shot of the climate factor the found of water. It investigates both how soil moisture influences finish severity, and conversely, how fire severity influences the hydrology of a soil. Based on this discussion a land management testimonial states that prescribed fires should be utilized during misty times of the year to cast up the positive effects for vegetation and to denigrate the negative effect of soil erosion. Rapid plant re reverseth is essential to the reclamation of a burned area, for plants greatly influence the hydrology of a soil. But for plants to grow back on a burned area, they require several nutrients whose concentrations are modified by fires. The ground level of these modifications are determined by a fires temperature, but there are a few general trends. Levels of match (Kutiel and Shaviv, 1993 and Marion et al., 1991) and pH (Kutiel and Shaviv, 1993) both increase during a fire. Conversely, nitrogen decreases during a fire (Kutiel and Shaviv, 1993, Marion et al., 1991). Chemical concentrations in burned soils are greatly affected by a fires intensity.

Soil Hydrology Under Fire Essay -- Geology Natural Nature 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 describ ed in the same 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 a rea, they require 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. Levels of phosphorus (Kutiel and Shaviv, 1993 and Marion et al., 1991) and pH (Kutiel and Shaviv, 1993) both increase during a fire. Conversely, nitrogen decreases during a fire (Kutiel and Shaviv, 1993, Marion et al., 1991). Chemical concentrations in burned soils are greatly affected by a fires intensity.
