Abstract: The large volume of sewage sludge (SS) generated with high carbon (C) and nutrient content suggests that its agricultural use may represent an important alternative to soil carbon sequestration and provides a potential substitute for synthetic fertilizers. However, emissions of CH4 and N2O could neutralize benefits with increases in soil C or saving fertilizer production because these gases have a Global Warming Potential (GWP) 25 and 298 times greater than CO2, respectively. Thus, this study aimed to determine C and N content as well as greenhouse gases (GHG) fluxes from soils historically amended with SS. Sewage sludge was applied between 2001 and 2007, and maize (Zea mays L.) was sowed in every year between 2001 and 2009. We evaluated three treatments: Control (mineral fertilizer), 1SS (recommended rate) and 2SS (double rate). Carbon stocks (0-40 cm) were 58.8, 72.5 and 83.1 Mg ha?1 in the Control, 1SS and 2SS, respectively, whereas N stocks after two years without SS treatment were 4.8, 5.8, and 6.8 Mg ha?1, respectively. Soil CO2 flux was highly responsive to soil temperature in SS treatments, and soil water content greatly impacted gas flux in the Control. Soil N2O flux increased under the residual effects of SS, but in 1SS, the flux was similar to that found in moist tropical forests. Soil remained as a CH4 sink. Large stores of carbon following historical SS application indicate that its use could be used as a method for carbon sequestration, even under tropical conditions.

Eucalyptus is a genus widely cultivated in many tropical and subtropical regions of the world as one of the main sources of raw materials for the pulp and paper industry. Identification of clones and selection of genotypes with desirable agronomic characteristics would be useful. We assessed eucalyptus full-sibs that varied in wood quality, using a combination of two-dimensional gel electrophoresis and mass spectrometry to identify differentially expressed proteins as candidates for quality markers. Thirty-one differently expressed proteins were identified, including three proteins of clone X1, four of clone X2, and 12 each of clones X3 and X4. These proteins are involved in various biological processes, including polyphosphate biosynthesis, catalytic activity, nucleotide excision repair, cellular metabolic processes, cell redox homeostasis, response to salt stress, response to temperature, oxidation and reduction processes, cellular water homeostasis, and protein phosphorylation. In the cambial region of each clone, the proteins ketol-acid reductoisomerase, uncharacterized protein MG428, receptor-like serine/threonine-protein kinase and a heat shock protein were found in larger quantities in clone X4 than in clone X1. These proteins are known to be related to protection against oxidative stress and biosynthesis of lignin. A high buildup of proteins involved in response to stress in the cambial region of eucalyptus would indicate clones with undesirable characteristics for use in the pulp and paper industry.
