• Abstract

  Cerrado is the second largest biome in Brazil, with approximately two million km2. This region is responsible for one third of the grain, half of meat and most of the cotton production, which is intended for the foreign market. However, the need to minimize environmental impact without yield reductions leads for alternatives to achieve sustainable production. The soil, as the basis for su…

• Abstract

  A global increase in the demand of wood is observed worldwide that is more and more satisfied by forest plantations (FP) and especially, in Brazil, by eucalypt plantations (EP). But their ability to meet wood demand is limited by competing land uses and their sustainability is a major concern, particularly with regard to serious long-term N and P deficits. Introducing N2-fixing species in…

• Abstract

  The Atlantic Rainforest originally occupied an area of 1.3 million square kilometers, though barely around 7.6 per cent of its original expanse has not been modified. It is still possible to find patches of the forest in the Serra do Mar and in the Serra da Mantiqueira, in the South-east of Brazil. Due to the scarcity of information on the structure and functioning of the dense ombrophilo…

• Abstract

  Atmospheric CO2 enrichment increases plants growth rate, raising total biomass production with direct interference in fiber, hemicellulose and lignin content, which has implications in ruminants feeding. The overall project objective is to evaluate the effects of the increased biomass production in response to increased atmospheric CO2 concentration in agricultural system. The goals inclu…

• Abstract

  In the current scenario where climate change drastically interfere in rainfall, causing drought never before registered in the state of São Paulo, together with lack of investment of public spheres in water conservation, we see the importance of studies on the watersheds, and their watersheds (<1,000 ha) forming, falling in our state. Specifically in the PCJ Basin (rivers Piracicaba, Capi…

• Abstract

  The integrated production systems such as crop-livestock integration (CLI) and crop-livestock-forest integration (CLFI) can intensify agricultural, livestock and forestry production, without adversely affecting the environment. In contrast, there is a long way to go to improve the management of these systems for different biomes. Indicators of soil quality (SQ), with emphasis on soil orga…

• Abstract

  Several field observations suggest that ectomycorrhizal fungi (ECMF) contribute to a number of key ecosystem functions such as carbon cycling, nutrient mobilization from soil organic matter and soil minerals, and water dynamics, and may form symbiotic associations with species of great economic importance, such as Eucalyptus and Pinus. However, the ecology of these fungi in planted forest…

• Abstract

  N is recognized as a growth-limiting nutrient in forest ecosystems. Generally, native forest and tropical forest plantation are stabilished in low fertility soil and have a eficient internal nutrient cycling. Intensively managed forests, are composed of symbiotic N fixing trees that may contribute directly to the N supply of neighbouring non-fixing trees. In situ labelling techniques usin…
