Integrate crop-livestock systems has been an efficient alternative for food production contributing to environmental sustainability and soil conservation. The objective of this study was to characterize some micromorphological properties of a Humic Rhodic Hapludox in integrated production systems. For this, four soil tillage systems were evaluated: conventional (CT), minimum (MT), no-tillage (NT), and chiseled no-tillage (CNT), under two annual ryegrass uses: grazing (G) and silage (S) at two soil depths (0–0.10 m and 0.10–0.20 m). Information about the size and shape distribution of the pores were obtained through the micromorphological analysis to determine the imagery porosity. The smallest porosities were found in the top-layer, independent of the management systems and ryegrass usages. The complex shaped pores of larger sizes (>1000 μm) had the greatest contribution to the imagery porosity in the sub-layer, although they were less frequent in the top-layer. Complex shaped pores were compressed due to the contrasting managements employed, decreasing their area and, consequently, influencing the fragmentation of this type of pores. As consequence, there was an increase in the amount of rounded shaped pores, especially ranging from 100 to 500 μm. The CNT management system improved the soil structure based on the results of porosity as well as the shape and size distributions of the pores.

整合农作物－牲畜系统已成为粮食生产的有效替代方案，有助于实现环境可持续性和土壤保护。这项研究的目的是在集成生产系统中表征腐殖质Rhapdic Hapludox的一些微观形态特征。为此，评估了四种土壤耕作系统：常规（CT），最小耕作（MT），免耕（NT）和凿式免耕（CNT），分别在两种黑麦草年度使用下：放牧（G）和青贮（S） ）在两个土壤深度（0–0.10 m和0.10–0.20 m）处。通过微形态分析获得有关孔的大小和形状分布的信息，以确定图像的孔隙率。在顶层发现了最小的孔隙率，与管理系统和黑麦草的使用无关。较大尺寸的复杂形状的毛孔（> 1000μm）对子层图像孔隙率的贡献最大，尽管在顶层不常见。复杂形状的孔由于采用了对比处理而被压缩，从而减小了它们的面积，因此影响了这种类型的孔的破碎。结果，圆形孔的数量增加，特别是在100至500μm的范围内。碳纳米管管理系统基于孔隙度以及孔的形状和尺寸分布的结果，改善了土壤结构。影响这类毛孔的破碎。结果，圆形孔的数量增加，特别是在100至500μm的范围内。碳纳米管管理系统根据孔隙率以及孔的形状和大小分布的结果改善了土壤结构。影响这类毛孔的破碎。结果，圆形孔的数量增加，特别是在100至500μm的范围内。碳纳米管管理系统根据孔隙率以及孔的形状和大小分布的结果改善了土壤结构。
