• Abstract

  The greenhouse gases (GHG) emissions associated with the use of nitrogen fertilizers, in particular N2O, are of utmost importance for the sustainability of ethanol from sugarcane. Previous studies point to relatively low N2O emissions when N fertilizers are applied in the sugarcane crop in São Paulo, but such emissions can increase considerably when fertilizers are used together with vina…

• Abstract

  The main goal of the Institutional Development Plan is to improve the work conditions and the development of products and services targeted to agribusiness production chains. These products and services, developed by the Agronomic Institute, should positively impact the scientific development and those technological packages that brings innovations to the agribusiness. On such a backgroun…

• Abstract

  Agricultural production systems based on monoculture or crop sequences with few species can lead to soil depletion and reduced microbial biodiversity. On the other hand, more complex systems tend to improve the biological properties of the soil, with a potential impact on sustainable production. Correction of acidity is a necessary practice in Brazilian acid soils and contributes to incre…

• Abstract

  Nitrogen fertilization has been one of the main sources of greenhouse gas (GHG) emissions to the atmosphere in sugarcane cultivation, mainly due to the emission of nitrous oxide (N2O). Recent studies indicate that the application of vinasse (concentrated-VC and in natura), a byproduct of ethanol production - especially with the addition of nitrogen (N) - results in significant increases i…

• Abstract

  The applications of remote sensing and associated technologies is one of the new frontiers of agriculture modernization with potentially great impacts on productivity, cost reduction, and the environment. More recently, the possibility of overflying with remotely controlled aircrafts, known as unmanned aerial vehicle (UAV), with high flight accuracy has reduced costs and brought flexibili…

• Abstract

  Different biologic processes are responsible for the nitrous oxide (N2O) production from soils. So, decipher the main players is of paramount importance due to global warming, since N2O is a potent greenhouse gas. It is well known that the combined application of organic residues with inorganic nitrogen (N) usually increase N2O emissions and change the structure of the soil microbiome. Th…

• Abstract

  Nitrous oxide (N2O) emissions resulting from soil application of N fertilizers represents ~40% of the total greenhouse gas emissions from sugarcane ethanol production. Several studies have indicated that the contribution of N fertilizers to the total emission is considerably greater when associated with agroindustry residues, such as vinasse. Conversely, recent studies have indicated that…

• Abstract

  Nitrogen (N) fertilization has been the main source of greenhouse gases (GHG) emissions to the atmosphere in sugarcane cultivation, mainly due to nitrous oxide (N2O) emission. In addition, some management practices of sugarcane production in Brazil may affect GHG emissions, such as the use of vinasse, a by-product of ethanol production. Recent studies indicate that the application of vina…
