In the course of evolution, a great variety of root systems have learned to overcome the many physical, biochemical and biological problems brought about by soil. … Websynthesize root turnover data for major biomes and plant life forms globally, (2) to generate broadscale patterns of root turnover along climatic gradients, and (3) to contrast regional and local environmental controls over root turnover. We illustrate this last objective by using regional patterns to predict site-level responses to global change.

WebOct 4, 2010 · The limited root growth and very short lifespan of roots at the surface soil layers was probably associated with high soil temperatures and tillage practices. The optimal range of temperature for peach root growth is between 12 and 22 °C (Tamási 1986), values that in summer are usually found in deeper soil layers in this region. In this ... WebRoot architectural traits, such as lateral branching and root hair density, are clearly advantageous for phosphorus-use efficiency. However, monitoring these traits and using them for selection in breeding programs is certainly not straightforward.

New roots grow partly into undepleted soil areas and can take up nutrients at a higher rate than old roots. ... This indicates that root turnover might be an efficiency mechanism, but not the only one ... hawthorne housing element
