Abstract Bioethanol from sugarcane is becoming an increasingly important alternative energy source worldwide as it considered to be both economically and environmentally sustainable. Besides being produced a tropical perennial grass with high photosynthetic efficiency, ethanol commonly associated low N fertilizer use because B razil, the world's largest producer, has demand. In recent years, several models have predicted that of in replacement fossil fuel could lead greenhouse gas ( GHG )...
Abstract Sugarcane straw, consisting of green tops and dry leaves, can be maintained on fields to improve soil quality, or harvested for bioenergy production. The optimum option between these two uses is still uncertain requires further study. This study, conducted across three crop cycles, provides an assessment the moisture, nutrients, ash, extractives, cellulose, hemicelluloses, lignin contents four sugarcane varieties seven regions south‐central Brazil. Suitability straw fractions...
This study assessed the production, land use, environmental impacts, and energy balance associated with ethanol biodiesel production in Argentina, Brazil, Colombia, Guatemala. These countries are considered developing economies produced 97% of biofuel Latin America, achieving 46 billion liters 2019. The implementation public policies (ie. RenovaBio, LCFS frameworks) to stimulate adoption low-carbon fuels may encourage production. Hence, official data for each country were used quantify...
Legal restrictions from burning sugarcane prior to harvest are causing a sharp increase in acreage which is harvested as green cane. The presence of thick trash mulch left after makes it difficult incorporate fertilisers the soil. Since large losses ammonia may occur when urea surface applied trash, important find ways improve urea-N use efficiency. urease inhibitor NBPT slows down hydrolysis and thus help decrease losses. Ammonia traps were set up seven fields covered with fertilised...
Abstract Nitrous oxide (N 2 O) from nitrogen fertilizers applied to sugarcane has high environmental impact on ethanol production. This study aimed determine the main microbial processes responsible for N O emissions soil fertilized with different sources, identify options mitigate emissions, and impacts of sources microbiome. In a field experiment, was as calcium nitrate, urea, urea dicyandiamide or 3,4 dimethylpyrazone phosphate nitrification inhibitors (NIs), coated polymer sulfur (PSCU)....
The environmental benefits of producing biofuels from sugarcane have been questioned due to greenhouse gas emissions during the biomass production stage, especially nitrous oxide (NO) associated with nitrogen (N) fertilization. objective this work was evaluate use nitrification inhibitors (NIs) dicyandiamide (DCD) and 3,4 dimethylpyrazole phosphate (DMPP) a controlled-release fertilizer (CRF) reduce NO urea, applied at rate 120 kg ha N. Two field experiments in ratoon cycle were performed...
Bioenergy is an important and feasible option for mitigating global warming climate change. However, large-scale land-use change (LUC) to expand bioenergy crops, such as sugarcane, raises concerns about the potential negative environmental socioeconomic side effects. Such effects are context-specific, depending on LUC scenario management practices, several co-benefits can be attained. We reviewed literature discussed how best practices affect key components of sustainability (e.g., soil...
Nitrous oxide (N2O) production in tropical soils cultivated with sugarcane is associated ammonia-oxidizing bacteria (AOB) and fungal denitrifiers. However, the taxonomic identities community diversities, compositions, structures of AOB denitrifiers these are not known. Here, we examined effects applying different concentrations an organic recycled residue (vinasse: regular non-concentrated or 5.8-fold concentrated) on dynamics denitrifier diversity composition greenhouse gas emissions during...
The area under mechanized sugarcane (Saccharum spp.) harvesting is expanding in Brazil, increasing the return of trash to soil. main questions regarding this management are: (i) after adopting unburned mechanical harvesting, how long will it take observe decreases fertilizer requirements, (ii) what be magnitude decrease and, (iii) impact short run removing for energy purposes nutrient cycling? This study aimed build an N prediction model term assessment contribution crop residues nutrition...
The maintenance of sugarcane (Saccharum spp.) straw on a soil surface increases the carbon (C) stocks, but at lower rates than expected. This fact is probably associated with management adopted during replanting. study aimed to assess impact C stocks and humification index organic matter (SOM) adopting no-tillage (NT) conventional tillage (CT) for A greater content stock was observed in NT area, only 0-5 cm layer (p < 0.05). Greater (0-60 cm) found under NT, when compared CT baseline. While...
Abstract Crop residues returned to the soil are important for preservation of quality, health, and biodiversity, they increase agriculture sustainability by recycling nutrients. Sugarcane is a bioenergy crop that produces huge amounts straw (also known as trash) every year. In addition straw, ethanol industry also generates large volumes vinasse, liquid residue production, which recycled in sugarcane fields fertilizer. However, both vinasse have an impact on N 2 O fluxes from soil. Nitrous...
Abstract Sugarcane ( Saccharum spp) crop has high social, economic and environmental importance for several regions throughout the world. However, increasing demand efficiency optimization of agricultural resources generates uncertainties regarding mineral fertilizer consumption. Thereby, organomineral fertilizers are to reduce conventional sources Thus, this study was carried out evaluate agronomic sugarcane performancies residual effect P K under fertilization. Growth technological...
Human activities are pushing earth beyond its natural limits, so recycling nutrients is mandatory. Microalgae highly effective in nutrient recovery and have strong potential as a sustainable wastewater treatment technology. Here, from black water (toilet wastewater) were recovered microalgal biomass, which was dried assessed fertilizer pot experiments compared with inorganic fertilizer. We deciphered the effects of biomass biofertilizer on plant growth quality biological processes linked to...
Organic vinasse, a residue produced during bioethanol production, increases nitrous oxide (N2O) emissions when applied with inorganic nitrogen (N) fertilizer in soil. The present study investigated the role of ammonia-oxidizing bacteria (AOB) community on N2O soils amended organic vinasse (CV: concentrated and V: non-concentrated) plus N fertilizer. Soil samples were evaluated at 11, 19, 45 days after application, bacterial archaea gene (amoA) encoding ammonia monooxygenase enzyme,...
Foliar fertilization has been used as a supplemental strategy to plant nutrition especially in crops with high yield potential. Applying nutrients small doses stimulates photosynthesis and increases performance. The aim of this study was evaluate the efficiency foliar application molybdenum (Mo) soybean maize. treatments consisted presence (+Mo) absence (-Mo) supplementation. Plant nutritional status, nitrate reductase (NR) activity, gas exchange parameters, photosynthetic enzyme activity...
