“…The losses of nitrogen by volatilization and leaching can reach 95-98% (Mackensen et al 1996). Cerri et al (1991) observed a reduction of 25% in soil carbon content two years after a plot was cleared, burned and a satisfactorily managed pasture established.…”

“…A considerable amount of soil nutrients is lost to the atmosphere after repeated fire events, including N and S losses by volatilization and P, K, Ca, and Mg losses by ash transport. Nutrients in the remaining ash might be lost by leaching to surface and groundwater (Kauffman et al 1993, Mackensen et al 1996, Sampaio et al 2003. In fertilization studies (Gehring et al 1999, Davidson et al 2004, Silva et al 2006, the secondary forest responded to application of P and N, indicating that soil nutrient limitation may reduce the vegetation regrowth and the biomass accumulation rate.…”

Amazon tropical forests are being replaced by pasturelands and croplands, but they sometimes revert to regrowth forest when abandoned after a period of agricultural use. Research suggests that this secondary regrowth is limited by climate and nutrient availability and, using a coupled biosphere-atmosphere model, we investigated patterns in the regrowth of the Amazon rainforest after a full deforestation event, considering different types of nutrient stress. We found that, over a 50 year regrowth period, the reduction of precipitation caused by large-scale deforestation was not sufficient to prevent secondary forest regrowth, but this decrease in precipitation combined with nutrient limitation, due to logging and frequent fires, did indeed prevent forest regrowth in central and southern Amazonia, leading to a savannization. These results are concerning, as the northern Mato Grosso region has the highest clearing rate in Amazonia. The low resilience of the forest under nutrient stress indicates that a large scale disturbance could greatly expand the area suitable for cropland, accelerating forest disappearance.
