The role of conservation soil management on soil and water protection at different spatial scales [PDF]

open access: yes, 2006
Agriculture has a direct impact on the soil environment, altering soil properties, surface characteristics and erosion risk. This has led to a move away from conventional tillage to the adoption of conservation practices, aiming to minimise soil ...

Deep roots and soil structure [PDF]

open access: yesPlant, Cell & Environment, 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 penetrometer resistance with depth are sufficiently great to confine most deep roots to elongating in ...
