Artificial macropores attract crop roots and enhance plant productivity on compacted soils.

摘要: The structure of compacted soils is characterised by decreased (macro-)porosity, which leads to increased mechanical impedance and fluid transport rates, resulting in reduced root growth crop productivity. Particularly with high impedance, macropores can be used roots as pathways least resistance. This study investigated how different soil physical states relate whole plant whether grow towards spots favourable conditions. Experiments were conducted under controlled field Soybean (Glycine max L.), wheat (Triticum aestivum L.) maize (Zea mays grown on uncompacted soil, artificial macropores. interactions between quantified using X-ray computed tomography. Active was observed for all three species. Roots grew either into (predominantly maize) or crossed them wheat). presence enabled species compensate early vigour at later developmental stages. These results show that sense their environment, enabling kinds root-macropore interaction indicated serve a path resistance source oxygen, both productivity soils.
