Plant physiology as affected by humified organic matter. Author(s): ZANDONADI, D. B.; SANTOS, M. P.; BUSATO, J. G.; PERES, L. E. P; FAÇANHA, A. R. In this review we discuss some of the most influential data available in literature, which have shaped this underexplored interface between the chemistry of the organic matter and the plant physiology... ... Repository: BDPA Publication year: 2013
Multivariate analysis of images in spectrophotometric methods: quantification of soil organic matter. Author(s): MORAIS, P. A. de O.; SOUZA, D. M. de; MADARI, B. E. Soil organic matter (SOM) is usually quantified by Walkley-Black titration method or using a spectrophotometric method. This study proposes an alternative method for quantification of SOM using digita... ... Repository: BDPA Publication year: 2021
Dynamic of organic matter in the conversion of primary forest in rubber tree in the central amazon region. Author(s): MOREIRA, A. The removal of primry forest causes a significant reduction of the microbial biomass of C and soil fertility. With the introduction of stands of rubber tress can be a continuos recovery of the amount... ... Repository: BDPA Publication year: 2007
Nanoecotoxicity of GO@AgNPs nanohybrid on zebrafish embryos: influence of natural organic matter and chorion membrane removal. Author(s): MEDEIROS, A. M. Z.; KHAN, L. U.; DELITE, F. S.; COSTA, C. A.; OSPINA, C. A.; ALVES, O. L.; CASTRO, V. L. S. S. de; MARTINEZ, D. S. T. Single-layer graphene oxide decorated with silver nanoparticles (GO@AgNPs) nanohybrid is an emerging material to applications in nanotechnology such as catalysis, biosensors, composites, and antimicro... ...

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
Evaluation of the stability of soil organic matter in different types of livestock management. Author(s): THIAGO. N. O. de S.; SEGNINI, A.; XAVIER, A. A. P.; OLIVEIRA, P. P. A.; PEREIRA, D. M. B. Repository: BDPA Publication year: 2016
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
Carbon in physical fractions and organic matter chemical composition of an acrisol after amazon forest burning and conversion into pasture. Author(s): LEAL, O. A.; DICK, D. P.; COSTA, F. de S.; KNICKER, H.; CARVALHO JÚNIOR, J. A. de; SANTOS, J. C. The aim of this study was to investigate impacts of Amazon Forest (AF) fire and conversion to pasture on carbon accumulation in particle size fractions and organic matter (OM) composition of an Acriso... ... Repository: BDPA Publication year: 2019
