Air cannot penetrate between the soil particles, making the soil oxygen-poor.

空气不能穿透土壤颗粒，这使得土壤中缺少氧气。

The fabric of coarse-grained soils primarily refers to the arrangement of soil particles, and it is the kernel factor for mechanical properties of coarse-grained soils.

粗粒土的组构主要指土颗粒的几何排列方式，是决定粗粒土宏观力学性质的根本因素。

The smaller the soil particles the greater is the surface area of the soil;

土粒愈小，则土壤的表面积愈大。

The study also noted that when tilled soil particles come in contact with air, soil organic matter is lost through the process of oxidation.

It was movement of particles of soil, but it has high roughness that reduces the transport capacity of sediment of the runoff.
