Changes in soil carbon, nitrogen, and phosphorus due to land-use changes in Brazil. Repositório Alice
GROPPO, J. D.; LINS, S. R. M.; CAMARGO, P. B.; ASSAD, E. D.; PINTO, H. S.; MARTINS, S. C.; SALGADO, P. R.; EVANGELISTA, B.; VASCONCELLOS, E.; SANO, E. E.; PAVÃO, E.; LUNA, R.; MARTINELLI, L. A..
Abstract. In this paper, soil carbon, nitrogen and phosphorus concentrations and stocks were investigated in agricultural and natural areas in 17 plot-level paired sites and in a regional survey encompassing more than 100 pasture soils In the paired sites, elemental soil concentrations and stocks were determined in native vegetation (forests and savannas), pastures and crop-livestock systems (CPSs). Nutrient stocks were calculated for the soil depth intervals 0-10, 0-30, and 0-60 cm for the paired sites and 0-10, and 0-30 cm for the pasture regional survey by sum stocks obtained in each sampling intervals (0-5, 5-10, 10-20, 20-30, 30-40, 40-60 cm). Overall, there were significant differences in soil element concentrations and ratios between different land...

Changes in soil carbon stocks in Brazil due to land use: paired site comparisons and a regional pasture soil survey. Repositório Alice
ASSAD, E. D.; PINTO, H. S.; MARTINS, S. C.; GROPPO, J. D.; SALGADO, P. R.; EVANGELISTA, B.; VASCONCELLOS, E.; SANO, E. E.; PAVÃO, E.; LUNA, R.; CAMARGO, P. B.; MARTINELLI, L. A..
Abstract. In this paper we calculated soil carbon stocks in Brazil using 17 paired sites where soil stocks were determined in native vegetation, pastures and crop-livestock systems (CPS), and in other regional samplings encompassing more than 100 pasture soils, from 6.58° S to 31.53° S, involving three major Brazilian biomes: Cerrado, Atlantic Forest, and the Pampa. The average native vegetation soil carbon stocks at 10, 30 and 60 cm soil depth were equal to approximately 29, 64, and 92 Mg ha-1, respectively. In the paired sites, carbon losses of 7.5 Mg ha-1 and 11.6 Mg ha-1 in CPS systems were observed at 10 cm and 30 cm soil depths, respectively. In pasture soils, carbon losses were similar and equal to 7.5 Mg ha-1 and 11.0 Mg ha-1 at 10 cm and 30 cm...

Inverting the carbon footprint in Brazilian agriculture: an estimate of the effects of the ABC plan. Repositório Alice
MARTINS, S. C.; ASSAD, E. D.; PAVÃO, E.; LOPES-ASSAD, M. L. R. C..
The Sectoral Plan of Mitigation and Adaptation to Climate Change, drafted in order to consolidate an Economy of Low Carbon Emission in Agriculture (ABC Plan), integrates the commitments made by Brazil to mitigate its emissions of greenhouse gases (GHG). The objective of this study is to estimate GHG emissions produced by the agriculture and livestock sector considering the adoption of three low carbon emission technologies (LCT) ? pasture recovery, integrated crop-livestock systems (ICLS), and integrated crop-livestock-forest systems (ICLFS). The GHG emissions were estimated considering the growth projections of the production of soybean, corn, rice, beans, cotton, wheat, sugarcane and pastures from 2012 to 2023. Two scenarios were considered: I - without...
