Soil carbon stock and humification in pastures under different levels of intensification in Brazil. Intensive management of tropical pastures has shown potential for greenhouse gas (GHG) mitigation due to high forage production and C accumulation in the soil. This study aimed to evaluate different p... ... Repository: BDPA Publication year: 2019
Performance evaluation of a portable laser-induced fluorescence spectroscopy system for the assessment of the humification degree of the soil organic matter. Repository: BDPA Publication year: 2015
Soil carbon stocks and humification index under brazilian livestock production systems in the atlantic forest biome. Repository: BDPA Publication year: 2016
Structural features of humic acids extracted from integrated crop-livestock-forest system. Soil organic matter (SOM) and their humic fractions (e.g., Humic Acids, HA) are considered a relevant soil quality indicator, due to its direct relation with biological, chemical and physical soil pro... ...

Applications of laser-induced breakdown spectroscopy for soil analysis, part I: Review of fundamentals and chemical and physical properties. Laser-induced breakdown spectroscopy (LIBS) has become a prominent analytical technique in recent years for real-time characterization of soil properties. However, only a few studies of soil chemical... ... Repository: BDPA Publication year: 2019
Organic matter of tropical soil with coffee growth in CO2 enriched atmosphere. The increase of atmospheric CO2 should result in higher carbon fixation by plants of the C3 photosynthetic cycle, such as coffee. However, not much is known about the relationship between atmospheric... ... Repository: BDPA Publication year: 2019
Atributos químicos e qualidade da matéria orgânica do solo em sistemas de colheita de cana-de-açúcar com e sem queima. O objetivo deste trabalho foi avaliar atributos químicos do solo, quantificar os teores e os estoques de C e N, e avaliar a qualidade química da matéria orgânica do solo em sistemas de colheita de can... ...

Does soil management system affect C content of a coarse sandy loam Amazonian Acrisol? The impact of No-till on the soil C content in comparison to Conventional Tillage (CT) depends greatly on the soil type, climate and initial C content. The main goal of this work was to investigate th... ... Repository: BDPA Publication year: 2018
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... ... Repository: BDPA Publication year: 2022
Structural characteristics of soil humic acids in coffee-cultivation systems: 13C NMR and analytical pyrolysis. Structural characterization of soil organic matter is still poorly understood in Brazilian agroecosystems. We aimed to identify the qualitative changes of soil humic acids as influenced by agroforestr... ... Repository: BDPA Publication year: 2011
