Aggregate stability by the “high energy moisture characteristic” method in an oxisol under differentiated management

Érika Andressa da Silva, Geraldo César de Oliveira, Bruno Montoani Silva, Carla Eloize Carducci, Junior Cesar Avanzi, Milson Evaldo Serafim

Studies testing the High Energy Moisture Characteristic (HEMC) technique in tropical soils are still incipient. By this method, the effects of different management systems can be evaluated. This study investigated the aggregation state of an Oxisol under coffee with Brachiaria between crop rows and surface-applied gypsum rates using HEMC. Soil in an experimental area in the Upper São Francisco region, Minas Gerais, was studied at depths of 0.05 and 0.20 m in coffee rows. The treatments consisted of 0, 7, […]

Soil losses from typic cambisols and red latosol as related to three erosive rainfall patterns

Regimeire Freitas Aquino, Marx Leandro Naves Silva, Diego Antonio França de Freitas, Nilton Curi, Junior Cesar Avanzi

Rainfall erosivity is one of the main factors related to water erosion in the tropics. This work focused on relating soil loss from a typic dystrophic Tb Haplic Cambisol (CXbd) and a typic dystrophic Red Latosol (LVdf) to different patterns of natural erosive rainfall. The experimental plots of approximately 26 m2 (3 x 8.67 m) consisted of a CXbd area with a 0.15 m m-1 slope and a LVdf area with 0.12 m m-1 slope, both delimited by galvanized plates. […]

Rainfall erosivity and rainfall return period in the experimental watershed of Aracruz, in the coastal plain of Espirito Santo, Brazil

Sérgio Gualberto Martins, Junior Cesar Avanzi, Marx Leandro Naves Silva, Nilton Curi, Lloyd Darrell Norton, Sebastião Fonseca

Knowledge on the factors influencing water erosion is fundamental for the choice of the best land use practices. Rainfall, expressed by rainfall erosivity, is one of the most important factors of water erosion. The objective of this study was to determine rainfall erosivity and the return period of rainfall in the Coastal Plains region, near Aracruz, a town in the state of Espírito Santo, Brazil, based on available data. Rainfall erosivity was calculated based on historic rainfall data, collected from […]

Potential of soil carbon sequestration in different biomes of Brazil

Soil is an important pool for C stocks and plays a fundamental role in greenhouse gas emissions and consequently in climatic changes. Land use change can cause either a negative or a positive effect in terms of greenhouse gas emissions to the atmosphere. However, the intensification of global warming has been confirmed, related mainly to the increase of greenhouse gas emissions from burning of fossil fuel, deforestation, and adoption of inadequate agricultural land management practices. An inadequate soil use does […]

Rainfall erosivity and erodibility of Cambisol (Inceptisol) and Latosol (Oxisol) in the region of Lavras, Southern Minas Gerais State, Brazil

Antonio Marcos da Silva, Marx Leandro Naves Silva, Nilton Curi, Junior Cesar Avanzi, Mozart Martins Ferreira

01/Dec/2009

Relatively few studies in Brazil have investigated soil erodibility, mainly for Cambisols (Inceptisols), due to the tediousness of data collection in natural rainfall experiments. Knowledge about erodibility and erosivity is important for conservation planning, which contributes to soil sustainability. This study aimed at evaluating the rainfall erosivity and erodibility of a typic dystrophic Tb Haplic Cambisol (Inceptisol) and a typic dystroferric Red Latosol (Oxisol) under natural rainfall, in Lavras, state of Minas Gerais, Brazil, between 1998 and 2002. Pluvial precipitation […]
