In such conditions root elongation is limited by high soil strength and not by the lack of water availability. Greenhouse gas fluxes: effects of physical con-, ditions. In Figure 3, it can be seen that at matric potentials of around 80 kPa, which would normally be considered well watered for field-grown crops, penetrometer pressures in excess of 2 MPa were recorded.
