Successive applications of pig slurry and pig deep litter may lead to an accumulation of copper (Cu) and zinc (Zn) fractions in the soil profile. The objective of this study was to evaluate the Cu and Zn forms and accumulation in a Sandy Typic Hapludalf soil after long-term application of pig slurry and deep litter. In March 2010, eight years after initiating an experiment in Braço do Norte, Santa Catarina (SC), Brazil, on a Sandy Typic Hapludalf soil, soil samples were collected from the 0-2.5, 2.5-5.0, 5-10 and 10-15 cm layers in treatments consisting of no manure application (control) and with applications of pig slurry and deep litter at two levels: the single and double rate of N requirement for maize and black oat succession. The soil was dried,...

ABSTRACT The purpose of this study was to evaluate Cu and Zn migration and fractions in sandy soil of vineyards. In Urussanga (SC), Brazil, soil samples were collected from a 4-year-old and 15-yearold vineyard, and from a forested area. In the soils, the chemical characteristics of Cu and Zn were analyzed by the EDTA method, which determines the fraction available in soil; 3050B method of the USEPA for total concentrations, which represents the pseudo-soil contents in the soil; and chemical fractionation, which estimates soluble fraction, exchangeable fraction, fraction associated with clay minerals, fraction associated with organic matter and residual fraction. The results show that there is accumulation of Cu and Zn in sandy soils cultivated with...

ABSTRACT: One of the main alternatives for the rational exploitation of the Caatinga biome’s natural resources is sustainable forest management. Soil organic carbon (SOC) and its fractions can be used to evaluate the conservation status of forest ecosystems after anthropic interventions. Therefore, the objective of this study was to evaluate the short-term effect of different forest management practices on the distribution of SOC fractions in the Caatinga area located in Contendas do Sincorá National Forest (BA). Three forest management practices (clear cutting, selective cutting by diameter and selective cutting by species) were evaluated, using the unmanaged Caatinga as a control. Soil samples were collected at the 0-10cm depth. The SOC was fractionated...
