“…As vegetation develops, the nutrient levels in the soil at any given time will be a balance between (a) retention of nutrients in biomass, (b) turn over and decomposition of biomass which adds nutrients to the soil, and (c) leaching of nutrients out of the zones of plant root accessibility. The recovery of soil to its previous functions varies with forest type (Brown and Lugo, 1990), soil type (Allen, 1985;Neill et al, 1997) and the type and intensity of past land use (Buschbacher et al, 1988;Neill et al, 1997).…”

“…In the Amazon region, many of these lands are abandoned after several years of use and often develop into secondary forests (Uhl et al 1981, Uhl and Jordan 1984, Uhl 1987. Species composition of primary and secondary forests may vary according to the history of land use (Mesquita et al 2001), intensity of anthropic perturbation (Buschbacher et al 1988), competitive interactions among species (Huston 1979) and the availability of seeds in the soil seed bank .…”

“…Tal vegetação provê uma combinação de árvores, arbustos e ervas, sendo geralmente instável e apresentando estádios sucessionais. Como a restauração da floresta ao seu estado original é muito difícil de ocorrer, a biomassa associada com pastagens e florestas secundárias em desenvolvimento é sempre menor que a da floresta original (BUSCHBACHER; UHL; SERRÃO, 1988).…”

“…Tal vegetação provê uma combinação de árvores, arbustos e ervas, sendo geralmente instável e apresentando estádios sucessionais. Como a restauração da floresta ao seu estado original é muito difícil de ocorrer, a biomassa associada com pastagens e florestas secundárias em desenvolvimento é sempre menor que a da floresta original (BUSCHBACHER; UHL; SERRÃO, 1988).O acúmulo de biomassa em florestas secundárias mostra um modelo de rápida acumulação em até 15 a 20 anos de pousio, contudo a taxa de incremento de biomassa está inversamente relacionada com o tempo de uso agrícola (HUGGES et al, 1992). Florestas secundárias em Porto Rico apresentam valores de biomassa similares à floresta madura somente após 40 anos de pousio (AIDE et al, 2000).…”
