Soil carbon and microbial processes in agriculture ecosystem. As global warming progresses, concerns also arise regarding the decline in agricultural productivity and soil degradation. On the other hand, the demand for food is increasing as the population grows,... ... Repositório: BDPA Ano de publicação: 2023
Pulse sequence induced variability combined with multivariate analysis as a potential tool for 13C solid-state NMR signals separation, quantification, and classification. Multivariate Curve Resolution (MCR) is a multivariate analysis procedure commonly used to analyze spectroscopic data providing the number of components coexisting in a chemical system, the pure spectr... ...

Spectroscopic investigation on the effects of biochar and soluble phosphorus on grass clipping vermicomposting. Seeking to evaluate the hypothesis that biochar optimises the composting and vermicomposting processes as well as their product quality, we carried out field and greenhouse experiments. Four grass cli... ... Repositório: BDPA Ano de publicação: 2022
Infrared spectroscopy refines chronological assessment, depositional environment and pyrolysis conditions of archeological charcoals. Based on infrared spectral characteristics, six archeological sample sets of charcoals from German (5) and Brazilian (1) sites, covering the time span from the nineteenth century CE to 3950 BCE, were... ...

Biochar amendment improves degraded pasturelands in Brazil: environmental and cost-benefit analysis. Most deforested lands in Brazil are occupied by low-productivity cattle ranching. Brazil is the second biggest meat producer worldwide and is projected to increase its agricultural output more than an... ... Repositório: BDPA Ano de publicação: 2019
Soil organic matter quality as indicator of ecosystem services. Soil organic matter (SOM), although a minor component in most soils, is primarily responsible for structure, function and sustainability of the ecosystems. Regarding the effects of soil degradation, t... ... Repositório: BDPA Ano de publicação: 2019
The quality of soil organic matter, accessed by 13C Solid State NMR, is more important than its content concerning pesticide adsorption. The need for food will increase by 59-98% from 2005 to 2050, and its global growth production has been achieved mainly through the intensive use of inputs such as pesticides and chemical fertilizers.... ...

Improving bone-based phosphate fertilizer by pyrolysis. Phosphorus is a macronutrient for all organisms, and its projected future scarcity generates a need for more efficient P recycling technologies. Because animal bones are rich in P, they could be emplo... ... Repositório: BDPA Ano de publicação: 2019
