Good plan- but divide each lawn piece into three equal sized sections so that in total you have 6, i.e

3x lawn fert
3x nothing

It's more of a standard scientific method to repeat in triplicate, it will lend more weight to your findings. Sorry to be picky, I'm an armchair scientist! At least it will give more conclusive 'evidence' if you get what I mean. You're going to take a visual estimate of lawn greeness?

I found the site for the "Organic Water Fertilizer." If anything, it is even worse than the label for Superthrive.

I'm with Iris...I don't think I need my BS in Biology (from many moons ago) to smell the BS in this 'gadget'.
As far as nutrient availability in soils, The Cation Exchange Capacity (CEC) is a measure of a soil's capacity to hold onto nutrients. It varies with the soil composition and pH. Clay has a relatively high CEC, organic matter even higher. You can submit soil samples to your local county exchange here in the US (Clemson Univ. here in SC for example) and get a sophisticated analysis of your growing medium for relatively little cost.

Avoid it!

Hogwash by any other name is still hogwash. (See the recent Stuporthrive) thread for discussion of horticultural scams, of which are are many.)
