Management impacts on soil organic matter of tropical soils. Author(s): CASTRO, G. S. A.; CRUSCIOL, C. A. C.; CALONEGO, J. C.; ROSOLEM, C. A. Increased soil organic matter (SOM) improves the cation exchange capacity of tropical weathered soils, and liming is required to achieve high yields in these soils. Despite a decrease in SOM in the sh... ... Repository: BDPA Publication year: 2015
The role of soil organic matter in sustainable crop production in the Tropics. Author(s): FAGERIA, N. K.; FERREIRA, E. P. B.; KNUPP, A. M. Soil organic matter has long been recognized as important indicator of soil productivity. Repository: BDPA Publication year: 2011
Losses and gains of soil organic carbon in grasslands in the Brazilian semi-arid region. Author(s): MEDEIROS, A. de S.; MAIA, S. M. F.; SANTOS, T. C. dos; GOMES, T. C. de A. Studies show that soil organic carbon (SOC) decreases between 3 % and 9 % in degraded grasslands in tropical regions, mainly due to the absence of techniques to enhance carbon contribution to soils. T... ... Repository: BDPA Publication year: 2021
Cover crops affect on soil organic matter fractions under no till system. Author(s): ENSINAS, S. C.; SERRA, A. P.; MARCHETTI, M. E.; SILVA, E. F. da; PRADO, E. A. F. do; LOURENTE, E. R. P.; ALTOMAR, P. H.; POTRICH, D. C.; MARTINEZ, M. A.; CONRAD, V. do A.; JESUS, M. V.; EL KADRI, T. C. The purpose of this research was to identify the soil organic matter (SOM) fractions changes in a crop rotation system under no-till system (NTS). This research was carried out from October 2010 to Fe... ... Repository: BDPA Publication year: 2016
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
Evolution of the soil organic matter content after 15 years of crop livestock system. Author(s): VIANA, J. H. M.; ALVARENGA, R. C.; ALBUQUERQUE FILHO, M. R. de; COSTA, A. M. da; MOURA, M. S. de Soil organic matter (SOM) is sensitive to changes in land use and is a key indicator of soil quality. This work evaluates the evolution of the organic matter of an oxisol under a crop-livestock integr... ... Repository: BDPA Publication year: 2021
Soil and plant responses to pyrogenic organic matter: carbon stability and symbiotic patterns. Author(s): SAGRILO, E. Soil amendment with pyrogenic organic matter (PyOM) can sequester carbon, increase mutualistic root symbioses with arbuscular mycorrhizal fungi and nitrogen-fixing rhizobia, and hence improve crop yie... ... Repository: BDPA Publication year: 2014
Trees and grass contribution to soil organic carbon in agroforestry systems. Author(s): TONUCCI, R. G.; GARCIA, R.; NAIR, V. Agroforestry systems have the potential to enhance carbon (C) sequestration in soil compared with treeless (agricultural) systems (Montagnini & Nair, 2004). When one type of vegetation is replaced wit... ... Repository: BDPA Publication year: 2015
Ecotoxicological potential of copper-based organic fungicide in non-target soil organisms. Author(s): SILVA, B. de A; SCORIZA, R. N.; CORREIA, M. E. F. Repository: BDPA Publication year: 2016
From forest to cropland and pasture systems: a critical review of soil organic carbon stocks changes in Amazonia. Author(s): FUJISAKI, K.; PERRIN, A.-S.; DESJARDINS, T.; BERNOUX, M.; BALBINO, L. C.; BROSSARD, M. Abstract - The impact of deforestation on soil organic carbon (SOC) stocks is important in the context of climate change and agricultural soil use. Trends of SOC stock changes after agroecosystem esta... ... Repository: BDPA Publication year: 2015
