Post-harvest biomass can be used as feedstock for energy production and alter N2O emissions from the soil, which is among the main issues determining bioethanol sustainability. To assess the effects of sugarcane straw return on gas emissions, we established a field experiment in which 0, 50, 75 or 100% (0, 5.65, 8.47 and 11.30 Mg/ha dry biomass, respectively) of the crop residues (straw) was left in the field during the first two ratoon crops. As fertilizer is applied in bands to sugarcane, we also investigated the contribution of different positions to the N2O emissions within the field. There was an interactive effect between straw and inorganic fertilizer, leading to a nonlinear effect of crop residues on the fertilizer emission factor (EF). However, straw consistently reduced N2O emissions from the field, acting mainly in the unfertilized areas in the field (P < 0.05). We observed that considering the typical EF used in the literature, the N2O-N emissions attributed to fertilizer ranged from 0.19 to 0.79 kg/ha, while the total emissions ranged from 3.3 to 5.2 kg/ha, from the highest amount of straw to the lowest. We conclude that overall, the fertilizer EF is not as relevant as the total emissions, based on this and other studies. Consequently, management practices might be more effective in improving the GHG balance than changing inorganic fertilizer use. We conclude that keeping up to 11 Mg/ha of straw with a large C:N ratio (>100:1) on site might increase sugarcane production sustainability by reducing the greenhouse gas emissions from the field.

The French Environment and Energy Management Agency (ADEME) launched in 2004 a national
call for proposal to develop and test soil bioindicators. The main objectives of the programme
were to (i) develop methods for measuring soil biodiversity and soil functions, (ii) use soil
bioindicators to monitor soil quality and (iii) identify relevant bioindicators or endpoints for
ecological risk assessment of soil contamination.
From 2004, 19 projects or PhD thesis aimed to develop and test in different situations
bioindicators based on the following biological organisms:
- Bacteria and fungi (indicators based on the diversity and activity),
- Collembola and Nematodes (indicators based on the diversity),
- Earthworms and total macrofauna (indicators based on the diversity, activity,
bioaccumulation and biomarkers),
- Snails (indicators based on the bioaccumulation),
- Birds and micrommals (indicators based on bioaccumulation and biomarkers)
- Plants (indicators based on the diversity, bioaccumulation and biomarkers).
Depending on the projects indicators are being tested in different situations combining different
soil types, landuses and practices: forest soils, organic farming, pastures, contaminated sites,
remediated soils. Investigation scales varied from mesocosms and field samples to regional
(e.g. landscape sampling) and even national sampling campaigns (e.g. based on the French
national monitoring network).
Based on the results obtained by all research teams and on the multivariate analysis of several
descriptors for each indicator it was possible to select batteries of indicators relevant for our
main objectives (i.e soil monitoring and ecological risk assessment of contaminants). These
batteries are now being tested on common pilot sites varying in soil types, soil contamination
and landuse. This last step currently started is needed to validate our batteries of indicators. MenosThe French Environment and Energy Management Agency (ADEME) launched in 2004 a national
