Relationships between labile soil organic carbon fractions under different soil management systems. Author(s): SOUZA, G. P. de; FIGUEIREDO, C. C. de; SOUSA, D. M. G. de ABSTRACT: The study of labile carbon fractions (LCF) provides an understanding of the behavior of soil organic matter (SOM) under different soil management systems and cover crops. The aim of this stu... ... Repository: BDPA Publication year: 2016
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
Characterization of organic matter in areas under different covers in the Savannah biome (SP) - Brazil. Author(s): PICCOLO, M. C.; BIELUCZYK, W.; REIS, L. C.; PEREIRA, M. G.; BALIEIRO, F. C. The identification and quantification of labile and recalcitrant soil organic matter (SOM) forms can be used to evaluate the impacts of management on soil quality (SQ). This study characterized the SO... ... Repository: BDPA Publication year: 2014
Biochar stable fraction quantification by thermochemical oxidation and assessement by 13C-NMR spectrocopy. Author(s): ALHO, C. F. B. V.; CROSS, A.; SOHI, S.; RODRIGUES, R. C.; NOVOTNY, E. H.; MAIA, C. M. B. de F.; LELIS, R. C. C. Although biochar is often regarded lized into carbon dioxide. However, it is unclear how much of this material is rapidly oxidized, that is, how much remain in the soil for NQPIGTRGTKQFU'ƑQTVUJCX... ... Repository: BDPA Publication year: 2013
Emission of CO2 from biochar-amended soils and implications for soil organic carbon. Author(s): SAGRILO, E.; JEFFERY, S.; HOFFLAND, E.; KUYPER, T. W. Soil amendment with pyrogenic organic matter (PyOM), also named biochar, is claimed to sequester carbon (C). However, possible interactions between PyOM and native soil organic carbon (SOC) may accele... ... Repository: BDPA Publication year: 2015
Determinação dos estoques de carbono e nitrogênio nas frações físicas da matéria orgânica em solos antrópicos (Terra Preta de Índio) e não antrópicos da Amazônia Central. Author(s): SOARES, R.; MADDOCK, J. E. L.; CAMPOS, D. V. B. de; MADARI, B. E.; MACHADO, P. L. O. de A. The soil organic matter, as the Amazonian Dark Earths, have functional compartments with different characteristics concerning composition and dynamics and these fractions can be evaluated using physic... ...
