True. Subangular blocky soil structure is generally considered more limiting than angular blocky soil structure.
In soil science, the term "angular blocky" refers to soil particles that are roughly cube-shaped with sharp edges, while "subangular blocky" describes slightly rounded blocky structures. The more pronounced shape and alignment of angular blocky aggregates can facilitate better drainage and aeration compared to subangular aggregates, which may hinder movement of water and air due to their softer edges and less pronounced structure.
Therefore, subangular blocky structures can be more limiting in terms of soil permeability and root penetration.
