Comment 1) It is defined as the effective soil depth above any barrier to root extension.2) Rooting depth is generally constrained by coherent hard rock or hardpans (dense soil layers). Physical limitations to rooting depth are also impediments to normal tillage, such that if plant roots cannot grow easily, it is unlikely that the plough can cut easily into the soil. Standard tillage depth is 15 to 25 cm.
