1. Management of rice straw in rice-soybean succession in tropical lowland
ABSTRACT This study aimed to analyze rice straw alternative managements to maximize the rice-soybean succession yield and to quantify their impacts on soil properties. The experiment was set up in a completely randomized design with six replicates. Nine rice straw managements were evaluated: straw burning (M1), straw harvesting (M2), straw incorporation with

2. Study on the pozzolanic activity of sugar cane straw ash produced using different pretreatments
This work systematically describes a laboratory study on different pretreatments of sugar cane straw to produce pozzolanic ash. Two procedures were used to accelerate the hydrolysis of celluloses and hemicelluloses and remove metallic impurities present in significant levels in sugar cane straw: hot water washing and acid leaching. Proximate analysis by ther

3. Soil management of sugarcane fields affecting CO2 fluxes
ABSTRACT The harvesting system of green sugarcane, characterized by mechanized harvesting and no crop burning, affects soil quality by increasing the remaining straw left on the soil surface after harvesting, thus, contributing to the improvement of physical, chemical, and microbiological soil attributes, influencing CO2 fluxes. This study aimed to evaluate

4. Sugarcane straw as a feedstock for xylitol production by Candida guilliermondii FTI 20037
Abstract Sugarcane straw has become an available lignocellulosic biomass since the progressive introduction of the non-burning harvest in Brazil. Besides keeping this biomass in the field, it can be used as a feedstock in thermochemical or biochemical conversion processes. This makes feasible its incorporation in a biorefinery, whose economic profitability c

5. 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

6. Leaching of nitrogen, potassium, cacium and magnesium in a sandy soil cultivated with sugarcane.
A lysimeter experiment was carried out with sugarcane aiming to evaluate the leaching of nitrogen derived from either urea (15N) or the soil/sugarcane crop residues. The leaching of K+, Ca2+, and Mg2+ was also evaluated. The experiment was a factorial 2x4. The influencing factors were: firstly, the differential addition of two kinds of sugarcane remains to t

7. Carbon and nitrogen stocks and greenhouse gases emissions from sugarcane areas in the Piracicaba region / Estoques de carbono e nitrogênio e emissões de gases do efeito estufa em áreas de cana-de-açúcar na região de Piracicaba
Concentrations of greenhouse gases (GHG), such as carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O), have increased since Industrial Revolution and the agricultural sector significantly contributes to the mentioned increase. Soils are important sinks of carbon (C) and nitrogen (N) and management practices could release part of these pools to the at

9. Spectral-temporal classification of orbital images to map sugarcane with pre-harvest straw burning / Classificação espectro-temporal de imagens orbitais para o mapeamento da colheita da cana-de-açúcar com queima da palha
In order to reduce the time established by law to cease the pre-harvest burning of sugarcane from 2021 to 2014, the Environmental Secretary of São Paulo State (SMA-SP) and the Sugarcane Industry Association (UNICA) signed, in June 2007, an Agro-Environmental protocol of intentions. Therefore, the monitoring of the sugarcane crop, with and without the practi

10. EFEITOS DO MANEJO DA PALHA NO RENDIMENTO DA SOQUEIRA E NA QUALIDADE DA CANA-DE-AÃÃCAR. / Effects of handling the straw in the yeld of ratoon and the quality of sugar cane.
The trash resulting from the cane harvest mechanically without burning (13 to 15 tonnes of dry.ha-1) normally has provided a good control of weeds in the area of stumps. Already in small areas, where the tips of cane is used for animal feed, the amount of straw remaining is the order of only 6 to 8 tonnes of dry .ha-1 and may not be effective in controlling
