1. Temporal effect of the soybean cultivation in the physical-chemical properties of the Mato Grosso state soil. / Efeito temporal da cultura da soja nos atributos físico-químicos do solo no Estado do Mato Grosso
Humanity as we know today is totally dependent in the large scale agriculture. We are getting close to the point where it will no longer be possible to expand or substitute agriculture areas. Making an evaluation of the agriculture system sustainability very important, to verify if they are fit to maintain there function as a food provider for a growing popu

2. Alterações no estoque e taxa de sequestro de carbono em um Latossoto vermelho submetido a sistemas de manejo.
The objective of this study was to quantify the changes of the total carbon (C) and total nitrogen (N) stock, and the variation of the C pools in monthly soil samples, and the C balance and C sequestration rates provoked by the soil tillage systems. The soil samples were accomplished in a long term experiment implanted in 1988, in the experimental station of

3. CARBON DYNAMICS ON A RHODIC HAPLUDOX ON SOIL TILLAGE AND CROP SYSTEMS / DINÂMICA DO CARBONO EM LATOSSOLO VERMELHO SOB SISTEMAS DE PREPARO DE SOLO E DE CULTURAS
The soil C stock is a consequence of the balance between the C losses by the CO2 emission (associate to the heterotrofic microorganisms activity) and erosion, and to C inputs, associate to organic compounds input by the vegetal photosynthesis process. In order to evaluate the soil tillage and crop systems regarding to the C inputs by the residues and the C l

4. Carbon sequestration potenciality of sugarcane harvesting without burning. / Potencialidade do sistema de colheita sem queima da cana-de-açúcar para o sequëstro de carbono.
The present work was led in experimental areas installed by COPERSUCAR, in clay soil - Hapludox (Usina São Martinho) and sandy soil - Quartzipsamment (Usina da Pedra) in the area of Ribeirão Preto (SP). The objective was to analyze the influence of the deposited trash on the soil surface in relation to the dynamics of carbon in the sugarcane agrosystem sin
