1. Descoloração e degradação do azo corante Vermelho GRLX-220 por ozonização
The discoloration and degradation of the textile dye RED GRLX-220 using the electrochemically generated ozone was investigated. Total discoloration was rapidly achieved in both acid and basic conditions. A pseudo-first order kinetics was observed for discoloration, influenced by pH and ozonation time. A considerable degree of mineralization (60%) was obtaine

2. Effects of management on physical properties and total organic carbon of a red-yellow argisol located in the Zona da Mata of Minas Gerais State / Efeitos do manejo em propriedades físicas e no carbono orgânico total de um argissolo vermelho-amarelo localizado na Zona da Mata Mineira
When the replacement of natural ecosystems for agroecosystems occurs, generally it is perceived a physical deterioration and a decline in soil carbon content. This degradation can be attributed to intensive soil tillage, exposing it to the action of climatic factors, causing erosion, mineralization of organic matter and oxidation of organic carbon in soil.

3. Estoque e fraÃÃes da matÃria orgÃnica e suas relaÃÃes com o histÃrico de uso e manejo de latossolos. / Organic matter storage and fractions and the historic of Latosol use and management
In cultivated areas, the reductions in the storage of soil organic matter (SOM) in average are 50%, in a period of cutting of the native vegetation and subsequent cultivation inferior to 10 years. The soil use and management practices exercise great influence on the MOS storage and fractions, since the vegetable covering and the soil management they modify t

4. Liming and aluminum forms in three places under no-tillage system. / Calagem e formas de alumínio em três localidades sob sistema de plantio direto.
Several agricultural areas under no-tillage system (NT) in Brazil present soils with low pH values and higher aluminum content. In spite of the apparently unfavorable condition to agriculture of such areas, high yields and lack of responses of crops to lime application have been observed, probably, because of aluminum chemistry in soils under no-tillage.
