Structural characterization of soil organic matter is still poorly understood in Brazilian agroecosystems. We aimed to identify the qualitative changes of soil humic acids as influenced by agroforestry- and full sun-coffee systems in the Atlantic Coastal Rainforest domain. The study was carried out in the Zona da Mata located in the state of Minas Gerais, Brazil. The specific studied sites were:agroforestry-coffee (AGF), Full sun coffee (FSC) and Native forest (NF) which was selected and used to determine the native or steady state condition of soil. Soil humic acids were extracted by using basic-acid medium, purified, and freeze-dried to a solid state to perform 13C NMR and analytical pyrolysis analyses. 13C NMR assignment of soil HAs from FSC system suggests an intensification of the process of humification of HAs structure. The higher aromaticity index of HAs from FSC compared to the AGF system confirmed this result. The relative abundance in each specific pyrolitic group was similar among the different land use, with exception to the higher amounts of lignin-like and lipids compounds in AGF compared to FSC system, and the higher abundance of N-compounds in FSC (37,0%) than in AGF (21,5%) system. Combining 13C NMR with Pyrolysis is an interesting tool to the study of structural features of HAs. Despite of the discrepancies, both techniques indicated that studied AGF systems favor the genesis of soil HAs with lower degree of humification when compared to FSC system, as a result of the influence of organic residues (fresh and old) from trees.

The rapidly changing global climate due to increased emission of anthropogenic greenhouse gases (GHGs) is leading to an increased occurrence of extreme weather events such as droughts, floods, and heatwaves. The three major GHGs are carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O). The major natural sources of CO2 include ocean?atmosphere exchange, respiration of animals, soils (microbial respiration) and plants, and volcanic eruption; while the anthropogenic sources include burning of fossil fuel (coal, natural gas, and oil), deforestation, and the cultivation of land that increases the decomposition of soil organic matter and crop and animal residues. Natural sources of CH4 emission include wetlands, termite activities, and oceans. Paddy fields used for rice production, livestock production systems (enteric emission from ruminants), landfills, and the production and use of fossil fuels are the main anthropogenic sources of CH4. Nitrous oxide, in addition to being a major GHG, is also an ozone-depleting gas. N2O is emitted by natural processes from oceans and terrestrial ecosystems. Anthropogenic N2O emissions occur mostly through agricultural and other land-use activities and are associated with the intensification of agricultural and other human activities such as increased use of synthetic fertiliser (119.4 million tonnes of N worldwide in 2019), inefficient use of irrigation water, deposition of animal excreta (urine and dung) from grazing animals, excessive and inefficient application of farm effluents and animal manure to croplands and pastures, and management practices that enhance soil organic N mineralisation and C decomposition. Agriculture could act as a source and a sink of GHGs. Besides direct sources, GHGs also come from various indirect sources, including upstream and downstream emissions in agricultural systems and ammonia (NH3) deposition from fertiliser and animal manure.
