I. INTRODUCTION
The impact of soil organic carbon (SOC) dynamics on the global carbon cycle is still largely uncertain despite studies of agricultura! activities and contrai emissions of greenhouse gases to the Earth's atmosphere. The knowledge of soil organic matter (SOM) dynamics could indicate altematives to increment carbon sequestration. The Kyoto Protocol has created global warming response opportunities by means of a clean development mechanism that allows countries like Brazil to receive investments from companies and governments wishing to reduce their emissions of greenhouse gases. According to such protocol, reforestation and reclamation of degraded areas are alternatives to increase the SOM and also the soil carbon sequestration. Land management practices as no- tillage have been proposed as a possible means to sequestrate atmospheric carbon, helping to refurbish sair fertility and replenish the organic matter lost as a result of previous agricultura! management practices. There are around 17 millions of hectares under no-tillage system in Brazil, representing about 30% of grain cultivated area. The use of no-tillage system has increased mainly over the last decade, and a significant contribution towards the reduction of soil CO2 emissions has been anticipated (Lal, 2001; Bayer et al., 2002). The present study aims to quantify the carbon storage in soils under different tillage systems used to sugar-Gane cultivation as well as to realize the characterization of humic acids extracted from these cultivated areas by electron spin resonance (ESR) and laser induced fluorescence (LIF) spectroscopies.
