There are exceptions to everything, and I disagree soil structure only impacts preferential flow. Understand that soil structure "by definition" states nothing about preferential flow nor can one derive potential water flow characteristics from the definition.
The combination or arrangement of primary soil particles into secondary units or peds. The secondary units are characterized on the basis of size, shape, and grade (degree of distinctness).

You stated soil structure is not important in turf, and I disagreed. That was followed with some research on your part and realization that soil structure is indeed important. So I guess thanks for clearing up your previously erroneous statement.
