Resumo: | The total soil organic carbon (C) is regulated by climatic factors, altitude, texture and soil depth. Due to higher storage in surface, it is common exponential model fit to the C content in the soil profile. This study was carried out in order to study the influence of climatic factors, altitude and soil depth on the vertical distribution (0-100 cm) of C in five cerrado fragments located in the municipalities of Januária and Bonito de Minas, MG. Soil samples were collected in the following layers: 0-10, 10-20, 20-40, 40-60 and 60-100 cm. The maximum and minimum levels of C varies depending on the sampling site, fragment and soil layer sampled; larger variations in the levels of C are noted for the 0-10 cm layer, whose C content did not correlate with root and litter biomasses, and with other soil C conditioning factors tested. Specific logarithmic equations are provided for each of the five fragments in order to estimate the C contents (in the 0-100 cm soil layers) as a function of the average temperature, precipitation, altitude and fragment soil layer sampled. |
