One important property of Organosols (Histosols) (and soils with high content of organic carbon) to predict use potential and degradation risks is the degree of subsidence (loss of mass and volume). In Organosols the subsidence risks vary according to the soil attributes, mainly the nature of organic matter and deposition environment. In this paper we studied 19 soil profiles from different parts of the country, collected and described according to procedures recommended by the SBCS (Brazilian Soil Science Society); the […]

As a result of anthropogenic activities such as mining, metal industry and agricultural fertilizer application, metal pollution has become one of the most serious environmental problems of today. Phytoremediation denotes the use of plants and micro-biota, together or without soil amendments, to extract, sequester, and/or detoxify pollutants, has been reported to be an effective, non-destructive, inexpensive and socially accepted technique to remediate polluted soils. The objective of this work was to evaluate the efficiency of organic amendments in the reduction […]
