Soil mechanics in relation to tillage, implements and root penetration in lowland soils
1985
Dexter, A.R. | Woodhead, T.
Basic soil mechanical properties were considered in terms of principal stresses and critical state soil mechanics. The recent hydraulic history of a soil and its present soil water content influenced its mechanical behavior. Soil mechanical properties that affect penetrometers were described in some detail, and the forces and pressures that affect tillage implements and elongating root tips were discussed. Mechanical factors that influence the ability of roots to penetrate hardpans were examined
