摘要: The effects of fire and alternative managements on soil vegetation native pastures were revised from several research works, jointing personal observations developed during almost 40 years in range areas Rio Grande do Sul, Brazil. Soil parameters such as potential acidity; aluminum concentration; basis saturation; others considered with production quality green forage dry matter the year; botanical composition; volumetric amount water soil; nutrients cycling through dead material; etc. general conclusion based results is that burning natural pastures, high altitude region Southern Brazil, must be avoided a routine practice, because it detrimental to environment, reduces yield quality, not sustainable practice.
