简介
- Liming represents a common agricultural practice for abating soil acidity.
- High doses of lime on the Oxisol surface increases the electronegativity of the soil system.
- High electronegativity increases clay dispersion in the uppermost soil layer.
- Clay migration led to a series of physical alterations in soil subsurface layers.
- Overliming can lead to the degradation of highly weathered soil structures.
Core Ideas
Liming represents a common agricultural practice for abating soil acidity. Nevertheless, elevated amounts of agricultural lime in Oxisols, with or without cultural residue addition, could alter soil physicochemical properties and impact soil structure. In this context, the physical, chemical, and structural behaviors of an Oxisol under the addition of lime and straw were assessed. Lime doses (0, 3.9, 7.8, and 15.6 Mg ha–1) were either applied on the surface or incorporated into the 0‐ to 5‐cm soil layer. Straw applications …
