Coconut residues increase light fraction of organic matter and water retention in semi-arid sandy soil under irrigated cultivation. Author(s): SILVA, I. E. B. da; DEON, M. D. I.; SILVA, D. J.; XAVIER, F. A. da S.; SANTOS, A. P. G.; SIGNOR, D. Coconut palm cultivation is associated with the generation of a large amount of residues, mainly from coconut shells, and their utilization in agriculture can represent an opportunity in the context o... ...

Soil organic matter fractions as a short-term indicator of carbon turnover under agricultural systems. Author(s): MATOS, E. da S.; CONCEIÇÃO, M. C. G. da; BIDONE, E. G.; RODRIGUES, R. de A. R.; CORDEIRO, R. C. Integrated crop-livestock-forest (ICLF) systems has been considered as an important strategy to enhance C sequestration. However, changes in soil C due to agricultural management practices, in general... ... Repository: BDPA Publication year: 2017
Organic matter fractions in a Quartzipsamment under cultivation of irrigated mango in the lower São Francisco Valley region, Brazil. Author(s): CARDOSO. J. A. F.; LIMA, A. M. N.; CUNHA, T. J. F.; RODRIGUES, M. A.; HERNANI, L. C.; AMARAL, A. J. do; OLIVEIRA NETO, M. B. de In this context, the aim of the present study was to evaluate the impact of growing irrigated mango on the organic carbon (OC) stocks, the C in humic substances, and the C of the heavy fraction and li... ...

Soil carbon stocks under amazonian forest: distribution in the soil fractions and vulnerability to emission. Author(s): MARQUES, J. D. de O.; LUIZÃO, F. J.; TEIXEIRA, W. G.; NOGUEIRA, E. M.; FEARNSIDE, P. M.; SARRAZIN, M. Transformations of natural ecosystems in tropical regions, which are usually covered by high-biomass forests, contribute to increased atmospheric CO2. Much of the carbon in forest ecosystems is stored... ... Repository: BDPA Publication year: 2017
Soil carbon fractions in rubber trees, pasture, and secondary forest areas. Author(s): DINIZ, A. R.; GUARESCHI, R. F.; PEREIRA, M. G.; FERNANDES, D. A. C.; BALIEIRO, F. de C.; SILVA, E. V. da; PICCOLO, M. de C. This study quantify the total organic carbon content, light fraction organic matter (LFOM), and soil organic matter fractions (from chemical and physical fractionations) in four different cultivation... ...

Carbon indices to assess quality of management systems in a Subtropical Acrisol. Author(s): ZANATTA, J. A.; VIEIRA, F. C. B.; BRIEDIS, C.; DIECKOW, J.; BAYER, C. Management systems to improve soil quality are essential for agricultural and environmental sustainability. We assessed the quality of soil management systems applied to a subtropical Acrisol in terms... ... Repository: BDPA Publication year: 2019
Can soil organic carbon pools indicate the degradation levels of pastures in the Atlantic Forest biome. Author(s): ROCHA JUNIOR, P. R. da; DONAGEMMA, G. K.; ANDRADE, F. V.; PASSOS, R. R.; BALIEIRO, F. de C.; MENDONÇA, E. de S.; RUIZ, H. A. In Brazil, a large part of the Atlantic Forest was deforested in pastures, which were developed on the basis of natural fertility and organic matter content of the new deforested soil. However, as tim... ... Repository: BDPA Publication year: 2014
