abstract = "In Amazonia, the main causes of deforestation are systems based on
slash-and-burn agriculture. The objective of this work was to
evaluate temporal changes in the soil chemical attributes after
the vegetation has been slashed and burned in an area of native
forest in the Western Amazon. For this study, four hectares of
forest in Cruzeiro do Sul, State of Acre, Brazil, was slashed and
burned. The soil in the study area was classified as Ultisol
(Argissolo Amarelo Distreifico tipico). Soil samples were
collected over the course of one year, the first one being
collected 16 hours after the burn and the others at 30, 60, 90,
150, 210, 270, and 360 days after the burn. The soil surface
layers were more sensitive to fire action. Ashes from vegetation
burn increased pH values, basic cations, and C values only in the
first months, resulting in higher basal saturation values (V%).
The practice of slash-and-burn after 12 months resulted in lower
values of pH, Ca, Mg, K, and P and higher values of Al and H, as
well as saturation by aluminum in the soil, indicating this
practice contributes to the reduction of soil fertility.",
