Oxygen Transport to Plant Roots: Modeling for Physical Understanding of Soil Aeration
Although there appears to be some evidence to suggest that the concentration of CO2 in the soil may have A model that couples the diffusion of O2 to plant roots at the an effect on plant growth, the major effect of poor microscale to diffusion of O2 through the soil at the macroscale is derived. The solution is complex, but if the length scales (Zr and Zm; aeration on plant growth is the lack o...
متن کاملHow significant to plant N nutrition is the direct consumption of soil microbes by roots?
The high degree to which plant roots compete with soil microbes for organic forms of nitrogen (N) is becoming increasingly apparent. This has culminated in the finding that plants may consume soil microbes as a source of N, but the functional significance of this process remains unknown. We used (15) N- and (14) C-labelled cultures of soil bacteria to measure rates of acquisition of microbes by...
متن کاملDeep roots and soil structure
There is convincing evidence for the benefits of deep rooting, especially in relation to drought resistance (Lopes & Reynolds, 2010; Uga et al., 2013). Modelling has shown that greater root depth allows increased water uptake and higher yields (Lilley & Kirkegaard, 2011). Deep rooting is thought to be improved by combinations of traits that confer steeper growth and an ability to penetrate stro...
متن کاملManagement Zones Soil Sampling: a Better Alternative to Grid and Soil Type Sampling?
Global positioning systems (GPS), yield monitors, various forms of remote sensing, new computer software, and variable rate technology are new tools available to producers. Intensive soil sampling and crop scouting methods that directly relate each sample or measurement with their geographical coordinates complement the new technological package. Soil testing is a diagnostic tool that adapts we...
