Aquatic plant sediment test
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 I did two main treatments: flow through with no water column fert additions and the other with 3x a week NO3/K/PO4/Traces The tap water source was the same as was the light and both have continuous flushing(so no interaction from sediment leaching could occur). The water column ferts where dosed at high concentrations and allowed to bath the plants for about 1 hour. Regards, Tom Barr |

Aquatic plant sediment test
Do you really mean sediment or substrate? I'm confused.
In article .com, wrote: 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. -- Need Mercedes parts? http://parts.mbz.org Richard Sexton | Mercedes stuff: http://mbz.org 1970 280SE, 72 280SE | Home pages: http://rs79.vrx.net 633CSi 250SE/C 300SD | http://aquaria.net http://killi.net |
