Última Aggregate stability in soils cultivated with eucalyptus 86 Avanzi,Junior Cesar; Norton,Lloyd Darrell; Silva,Marx Leandro Naves; Curi,Nilton; Oliveira,Anna Hoffmann; Silva,Mayesse Aparecida da. The objective of this work was to evaluate the aggregate stability of tropical soils under eucalyptus plantation and native vegetation, and assess the relationships between aggregate stability and some soil chemical and physical properties. Argisols, Cambisol, Latosols and Plinthosol within three eucalyptus-cultivated regions, in the states of Espírito Santo, Rio Grande do Sul and Minas Gerais, Brazil, were studied. For each region, soils under native vegetation were compared to those under minimum tillage with eucalyptus cultivation. The aggregate stability was measured using the high-energy moisture characteristic (HEMC) technique, i.e., the moisture release curve at very low suctions. This method compares the resistance of aggregates to slaking on a...

Ano: 2011 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0100-204X2011000100012 Spatial distribution of water erosion risk in a watershed with eucalyptus and Atlantic Forest 64 Avanzi,Junior Cesar; Silva,Marx Leandro Naves; Curi,Nilton; Norton,Lloyd Darrell; Beskow,Samuel; Martins,Sérgio Gualberto. The process of water erosion occurs in watersheds throughout the world and it is strongly affected by anthropogenic influences. Thus, the knowledge of these processes is extremely necessary for planning of conservation efforts. This study was performed in an experimental forested watershed in order to predict the average potential annual soil loss by water erosion using the Universal Soil Loss Equation (USLE) and a Geographic Information System (GIS), and then compared with soil loss tolerance. All the USLE factors were generated in a distributed approach employing a GIS tool. The layers were multiplied in the GIS framework in order to predict soil erosion rates. Results showed that the average soil loss was 6.2 Mg ha-1 yr-1. Relative to soil loss... Tipo: Info:eu-repo/semantics/article Palavras-chave: Forest systems; Soil losses; USLE; GIS; Coastal plain.
