1. Soil Organic Matter Quality in Jatropha spp. Plantations in Different Edaphoclimatic Conditions
ABSTRACT The substitution of native vegetation by agricultural ecosystems can change the quantity and quality of soil organic matter (SOM), and the intensity of these changes depends on the soil type, climate, and land use. The objective of this study was to evaluate the quality of organic matter in chronosequences of Jatropha cultivation in contrasting soil

2. Carbon stock and humification index of organic matter affected by sugarcane straw and soil management
The maintenance of sugarcane (Saccharum spp.) straw on a soil surface increases the soil carbon (C) stocks, but at lower rates than expected. This fact is probably associated with the soil management adopted during sugarcane replanting. This study aimed to assess the impact on soil C stocks and the humification index of soil organic matter (SOM) of adopting

3. Compostagem de esterco de galinha: composiÃÃo quÃmica da matÃria orgÃnica e extraÃÃo de substÃncias hÃmicas / Chicken manure composting: organic matter composition and humic substances extraction
The agro-industrial activities are responsible for the generation of large amounts of organic waste, and composting is an efficient process for the treatment of such waste; humification degree is an important parameter for determining the quality of the compost produced. This study aims to evaluate the dynamics of humification of organic matter during compos

4. Physical-chemical characterization and comparison of digestion methods of organic residues / CaracterizaÃÃo fÃsico-quÃmica e comparaÃÃo de mÃtodos de digestÃo de resÃduos orgÃnicos
The use of residues in agriculture can be a viable alternative from the point of view of the environment and economics purposes. However, it is necessary characterize in an adequate way the different residues available, in order to establish correct application rate, improve use efficiency, and avoid environmental pollution. The objective of this work was to

5. Microbial degradation and humification of the lawn care pesticide 2,4-dichlorophenoxyacetic acid during the composting of yard trimmings.
The fate of the widely used lawn care herbicide 2,4-dichlorophenoxyacetic acid (2,4-D) during the composting of yard trimmings consisting of primarily leaves and grass is an important unexplored question. In this study, we determined the extent of 2,4-D mineralization, incorporation into humic matter, volatilization, and sorption during the composting of yar
