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
Biogeochemistry of dissolved organic matter and inorganic solutes in soil profiles of tropical pasturelands. Author(s): SANTOS, J. V. DOS; GORANOV, A. I.; BENTO, L. R.; OLIVEIRA, P. P. A.; PEZZOPANE, J. R. M.; BERNARDI, A. C. de C.; SÁ, I. P. DE; NOGUEIRA, A. R. de A.; MARTIN NETO, L.; HATCHER, P. G. Tropical soils play a critical role in the global biogeochemical cycles and are essential for maintaining the Earth's carbon balance. Understanding the dynamics of dissolved organic matter (DOM) is pa... ... Repository: BDPA Publication year: 2024
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
Organic matter of an Amazonian sandy soil as affected by forest burning. Author(s): DICK, D. P.; LIMA, M. O.; COSTA, F. de S.; COSTA, J. B. da In the Amazon region, forest burning is still common in spite of the governmental control. Pyrogenic C produced by the fire, due to its aromatic structure, may represent a C pool of small turnover rat... ... Repository: BDPA Publication year: 2017
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
Organic matter as affected by conservation agriculture of cassava and maize cultivation in an acrisol from Southwestern Brazilian Amazon. Author(s): DICK, D. P.; AQUINO, I. O.; COSTA, F. de S.; DIAS, C. T. S. In the Brazilian Southwestern Amazon, food security agriculture predominates in smallholder farms where cassava cultivation is conducted under conventional tillage (CT). We investigated the impact of... ... Repository: BDPA Publication year: 2022
