Resumo: | The no-tillage system (NTS) and more recently, the crop-livestock integration (CLI) are very used for grain production in the Cerrado biome. This, the soil organic matter (SOM) is one of the main components responsible for maintaining the quality of tropical soils. This study aimed to quantify the levels of total organic carbon (TOC), total nitrogen (total N), water soluble carbon (WSC) and carbon of humic fractions in areas with different land use systems in the Cerrado of Goias. The farming systems were used: CLI (brachiaria + corn/beans/cotton/soybean) and NTS (sunflower/millet/soybean/corn) andas a reference, area native Cerrado vegetation (Cerradão). We collected soil samples at 0-10, 10- 20, 20-30 and 30-40 cm. The contents of TOC, total N, WSC, humin fraction carbon (C-HUM), humic acid fraction (C-HAF) and fulvic acid fraction (C-FAF). The area of Cerradão had the highest TOC, total N, C-HUM and C-FAH in the surface layer (0-10 cm). The levels of WSC and humic fractions of SOM showed significant differences between the systems of land use and sampling depths. The highest levels of C-HAF were found in the area of CLI, at 0-10 and 20-30 cm. The CLI systems and NTS did not differ for the TOC and total N except for N in layer 20-30 cm. The system CLI favors the formation of C-HUM compared to the NTS. The CLI system leads to lower levels of WSC and higher C-FAF compared with the NTS, which has higher levels of WSC and C-FAH. The use of WSC and carbon of humic fractions was more efficient to identify differences from the land use systems evaluated (NTS, CLI and Cerradão) when compared to the TOC for the climatic conditions of this study. |

Neste, a matéria orgânica do solo (MOS) é um dos principais componentes responsáveis pela manutenção da qualidade dos solos tropicais. Este trabalho objetivou quantificar os teores de carbono orgânico total (COT), nitrogênio total (N-total), carbono solúvel em água (CSA) e carbono das frações húmicas em áreas com diferentes sistemas de uso do solo no Cerrado goiano. Os sistemas agrícolas utilizados foram: ILP (milho+braquiária/feijão/algodão/ soja) e SPD (girassol/milheto/soja/milho) e como referência, área de vegetação nativa de Cerrado (Cerradão). Foram coletadas amostras de terra nas profundidades de 0-10; 10-20; 20-30 e 30-40 cm. Foram determinados os teores de COT, N-total, CSA, carbono da fração humina (C-HUM), fração ácido húmico (C-FAH) e fração ácido fúlvico (C-FAF). A área de Cerradão apresentou os maiores teores de COT, N-total, C-HUM e C-FAH na camada superficial (0-10 cm). Os teores de CSA e das frações húmicas da MOS apresentaram diferenças significativas entre os sistemas de uso do solo e as profundidades de amostragem. Os maiores teores de C-FAH foram encontrados na área de ILP, nas camadas de 0-10 e 20-30 cm. Os sistemas de ILP e SPD não apresentaram diferenças para o COT e N-Total, exceto para N na camada de 20-30 cm. O sistema de ILP favorece a formação do C-HUM em comparação ao SPD. O sistema de ILP acarreta em menores teores de CSA e maiores de C-FAF quando comparado com o SPD, que apresenta maiores teores de CSA e C-FAH. O uso do CSA e carbono das frações húmicas foi mais eficiente para identificar diferenças provenientes dos sistemas de uso do solo avaliados (SPD, ILP e Cerradão) quando comparado ao COT, para as condições edafoclimáticas do presente estudo.UEL2013-12-11info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa Empírica de Campoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/1167810.5433/1679-0359.2013v34n6p2637Semina: Ciências Agrárias; Vol. 34 No. 6 (2013); 2637-2654Semina: Ciências Agrárias; v. 34 n. 6 (2013); 2637-26541679-03591676-546Xreponame:Semina.
