| dc.description | Soil organic matter (SOM) and their humic fractions (e.g., Humic Acids, HA) are considered a relevant soil quality indicator, due to its direct relation with biological, chemical and physical soil properties, permitting to evaluate agricultural management impacts. Soils under Integrated Crop-Livestock-Forest Systems (CLFS) have the potential to capture and sequester carbon, in the form of increasing SOM content, contributing to the mitigation of greenhouse gas emissions from agriculture. In this study aimed was characterization the HA extracted from CLFS and Native Forest (NF) soils using elemental analysis (CHN), fluorescence spectroscopy and electronic paramagnetic resonance (EPR). For this, samples of a dystrophic Red-Yellow Latosol (Oxisol) were collected from the experimental site of a research station called Embrapa Pecuária Sudeste (located in the Southeast of Brazil), five years after the implementation of the agricultural integrated systems. Results showed positive correlation between HA humification index with semiquinone-type free radical present in these soils (R = 0.69). Therefore, these results showed that HA from these integrated systems have a more stable and humified soil organic matter than in native forest, contributing to soil carbon compounds with higher chemical stability and possibly with longer lifetime in the soil. | |
