Última Initial Recovery of Organic Matter of a Grass-Covered Constructed Soil after Coal Mining Rev. Bras. Ciênc. Solo Leal,Otávio dos Anjos; Castilhos,Rosa Maria Vargas; Pinto,Luiz Fernando Spinelli; Pauletto,Eloy Antonio; Lemes,Elisa Souza; Kunde,Roberta Jeske. ABSTRACT Revegetation is essential to improve the quality of constructed soils. This study investigated effects of perennial grasses on total organic carbon (TOC) stock, organic matter (OM) fractions and on quality of a recently constructed soil, after coal mining. Soil samples were collected from the 0.00-0.03 m layer two years after the beginning of the experiment. The treatments consisted of Cynodon dactylon cv vaquero (T1); Urochloa brizantha (T2); Panicum maximun (T3); Urochloa humidicola (T4); Hemarthria altissima (T5); Cynodon dactylon cv tifton (T6); bare constructed soil (T8); and natural soil (T9). The treatments with grass species increased the TOC stock by 57 % and increased the OM lability in comparison with T8. Higher C accumulation in the...

I - Humic Substances and Chemical Characterization Rev. Bras. Ciênc. Solo Leal,Otávio dos Anjos; Castilhos,Rosa Maria Vargas; Pauletto,Eloy Antonio; Pinto,Luiz Fernando Spinelli; Fernandes,Flávia Fontana; Penning,Letiane Helwig; Rosa,Carla Machado da. After open coal mining, soils are “constructed”, which usually contain low levels and quality of organic matter (OM). Therefore, the use of plant species for revegetation and reclamation of degraded areas is essential. This study evaluated the distribution of carbon (C) in the chemical fractions as well as the chemical characteristics and humification degree of OM in a soil constructed after coal mining under cultivation of perennial grasses. The experiment was established in 2003 with the following treatments: Hemarthria altissima (T1), Paspalum notatum (T2), Cynodon dactilon (T3), Urochloa brizantha (T4), bare constructed soil (T5), and natural soil (T6). In 2009, soil samples were collected from the 0.00-0.03 m layer and the total organic carbon stock...
