2. Soil organic matter fractions affected by N-fertilizer in a green cane management in Brazilian Coastal Tableland
ABSTRACT The recent approach of eliminating the use of fire for sugarcane harvesting (green cane) resulted in managing the crop on a trash-blanketed soil, which changed the content and dynamic of carbon and the nitrogen requirement. These alterations are relevant due to economic and environmental aspects of sugarcane production systems. This study aimed to e

3. Sugarcane trash levels in soil affects the fungi but not bacteria in a short-term field experiment
Abstract The sugarcane in Brazil is passing through a management transition that is leading to the abolition of pre-harvest burning. Without burning, large amounts of sugarcane trash is generated, and there is a discussion regarding the utilization of this biomass in the industry versus keeping it in the field to improve soil quality. To study the effects of

4. Technical and economic assessment of trash recovery in the sugarcane bioenergy production system
Mechanized sugarcane (Saccharum spp.) harvest without burning has been increasingly adopted in Brazil, increasing trash availability on the field. This study aims at showing the importance of using an integrated framework tool to assess technical and economic impacts of integral harvesting and baling trash recovery strategies and different recovery rates as

5. Contribution of nitrogen from sugarcane harvest residues and urea for crop nutrition
Sugarcane (Saccharum spp.) harvested without burning provides a substantial amount of remains (trash) on soil profiles which can be decomposed and release nutrients contributing to reduce fertilizer needs. The contribution of nitrogen (N) from sugarcane plant residues and fertilizer in sugarcane nutrition was assessed. Plant cane treatments were micro plots

6. Impact of sugarcane trash on fertilizer requirements for São Paulo, Brazil
The area under mechanized sugarcane (Saccharum spp.) harvesting is expanding in Brazil, increasing the return of trash to the soil. The main questions regarding this management are: (i) after adopting unburned mechanical harvesting, how long will it take to observe decreases in fertilizer requirements, (ii) what will be the magnitude of this decrease and, (i

7. Assessment of sugarcane trash for agronomic and energy purposes in Brazil
Due to new possibilities for using sugarcane (Saccharum spp.) trash for electricity generation, and the production of 2nd generation ethanol and others chemicals, the interest for its recovery has increased. However, the question of how much trash can be removed from sugarcane field still needs to be clarified. This study evaluated the amount of dry matter,

9. Simulação do efeito de palhada e adubação nitrogenada na produtividade de cana-de-açúcar / Simulation of trash and nitrogen effects on sugarcane yield
A demanda crescente por fontes energéticas alternativas, em detrimento dos combustiveis fósseis, tem dado destaque ao Brasil no cenário inernacional como modelo de produção de energia renovável e atraído investimentos massivos ao setor sucroenergético brasileiro nacional. Para garantir a segurança financeira do negócio, é necessário que a produç

10. Desenvolvimento e produção de cana-de-açúcar em sistema sob palhada
Due to environmental constraints, lack of manpower and the search for better efficiency, the harvesting of sugar cane tends to be mechanized, causing large amount of straw is available in this new system. There are benefits to soil and culture provided by this residue. However, it was discussed what amount would be sufficient to promote these benefits and wh

11. Desenvolvimento e otimização de processos de produção de etanol de primeira e segunda geração e eletricidade a partir da cana-de-açúcar / Development and optimization of first and second generation bioethanol and electricity production processes from sugarcane
Increase on biofuels demand has motivated the production of bioethanol from lignocellulosic materials (2nd generation ethanol). Bioethanol has been produced in large scale in Brazil from sugarcane (1st generation ethanol) for more than 30 years. Large amounts of lignocellulosic materials (bagasse and trash) are generated during sugarcane processing; bagasse

12. Study of cogeneration systems in sugar-ethanol industry using sugarcane bagasse and trash / Estudo de sistemas de cogeração em usinas de açúcar e álcool, com utilização do bagaço e palha da cana
A caldeira é um dos principais equipamentos do setor sucroalcooleiro, ela utiliza o bagaço de cana, como combustível, para geração de vapor. As primeiras caldeiras produziam vapor de média pressão, e utilizavam para geração de vapor todo bagaço gerado na usina, sendo pouco eficientes energeticamente. Na década de 1990, com a descentralização do
