Resumo: | The objective of this work was to evaluate the stability of aggregates, light organic matter content (LOM), distribution of total organic carbon (TOC) and nitrogen (N) contents, and natural abundance of 13C and 15N in aggregates of a clayed Oxisol under no-tillage (NT) with crop-livestock integration (CLI), in comparison to an area under NT without CLI, and an area of natural Cerrado, in Montividiu, GO, Brazil. Soil samples were collected at the layers of 0–5 and 5–10 cm, in a completely randomized block design. The mass distribution of aggregates, mean weight diameter (MWD), geometric mean diameter (GMD), and LOM were evaluated, and the levels of TOC, N, δ13C and δ15N aggregates were quantified. The Cerrado area had the highest values of MWD, GMD and LOM. The NT-CLI showed higher values of MWD, GMD, TOC, N and LOM in the layer of 5–10 cm than the area of NT without brachiaria. The NT-CLI increased the indices of soil aggregation (0–5 and 5–10 cm), the levels of LOM (5–10 cm), TOC and N (0–5 cm) and the formation of water-stable aggregates (5–10 cm) in comparison to the NT without palisade grass. |

Foram coletadas amostras de solo nas camadas de 0–5 e 5–10 cm, em delineamento inteiramente casualizado. Foram avaliados distribuição da massa dos agregados, diâmetro médio ponderado (DMP), diâmetro médio geométrico (DMG) e MOL, e foram quantificados os teores de COT, N, δ13C e δ15N dos agregados. A área de Cerrado apresentou os maiores valores de DMP, DMG e MOL. O SPD-ILP apresentou valores maiores de DMP, DMG, COT, N e MOL na camada 5–10 cm do que o SPD, sem braquiária. O SPD-ILP promoveu aumentos nos índices de agregação do solo (0–5 e 5–10 cm), nos teores de MOL (5–10 cm), COT e N (0–5 cm) e na formação de agregados estáveis em água (5–10 cm), em comparação ao SPD, sem braquiária.

Soil samples were collected at the layers of 0–5 and 5–10 cm, in a completely randomized block design. The mass distribution of aggregates, mean weight diameter (MWD), geometric mean diameter (GMD), and LOM were evaluated, and the levels of TOC, N, δ13C and δ15N aggregates were quantified. The Cerrado area had the highest values of MWD, GMD and LOM. The NT-CLI showed higher values of MWD, GMD, TOC, N and LOM in the layer of 5–10 cm than the area of NT without brachiaria. The NT-CLI increased the indices of soil aggregation (0–5 and 5–10 cm), the levels of LOM (5–10 cm), TOC and N (0–5 cm) and the formation of water-stable aggregates (5–10 cm) in comparison to the NT without palisade grass. |
