Abstract
RODRIGUEZ, Lina Marcela et al. Comparison of GHG emissions scenarios from fossil combustion and fertilization in commercial and organic sugar cane crops through simulation models. Rev. P+L [online]. 2017, vol.12, n.2, pp.80-91. ISSN 1909-0455. https://doi.org/10.22507/pml.v12n2a7.
Introduction.
Fossil combustion and fertilizer decomposition are the main sources of greenhouse gas emissions in sugarcane crops.
Objective.
Perform a comparative analysis of Carbon Footprint scenarios in commercial and organic sugarcane crops.
Materials and Methods.
Carbon Footprint was calculated based on IPCC Guidelines; emission projections were obtained through system dynamics and the opportunities for emissions reductions were obtained with sensitivity analysis.
Results.
The first CO2 emission model for fossil combustion obtained a level of 1.87 tCO2-eq/ha in a commercial crop and 1.67 tCO2-eq/ha in an organic crop, projected for 25 years. The second N2O emissions model for fertilizer decomposition achieved a level of 6.l8 tCO2-eq/ ha in a commercial crop and 4.62 tCO2-eq/ha in an organic crop, simulated for 5 years.
Conclusion.
The adoption of specific agricultural practices in each agro-ecological zone represents an opportunity to reduce CO2 emissions, which corresponds to 3l% for commercial crop and 0.49% for organic crop. A proper fertilizer application according to soil characteristics and the crop's harvest cycle contributes to reducing I2O emissions by up to 40% for commercial crop and 25% for organic crop.
