Do you really mean sediment or substrate? I'm confused.

I've just completed a fairly extensive sediment growth comparison test
using milfoil as a study plant.

The results are a little surprising.

ADA Aqua soil
Rich clay black Delta Sediment
Tahoe sandy soil
Soil Master Select(old Turface)
Sand + garden soil(3:1)
Plain sand

Are these the results in order? Do we have any quantitive feel for the
differences?

I'd be interested if you compared Ma Reimers technique of manure under sand.
