Deep roots and soil structure. [PDF]

Plant Cell Environ, 2016
In this opinion article we examine the relationship between penetrometer resistance and soil depth in the field. Assuming that root growth is inhibited at penetrometer resistances > 2.5 MPa, we conclude that in most circumstances the increases in ...

Interactions between soil structure dynamics, hydrological processes, and organic matter cycling: A new soil‐crop model

European Journal of Soil Science
The structure of soil is critical for the ecosystem services it provides since it regulates many key soil processes, including water, air and solute movement, root growth and the activity of soil biota.
