Simple Fertilizer Uptake Test
« on: June 23, 2013, 05:02:47 PM »

See the link to an Evernote "note" below the message.
PVBI members might be interested in this very basic experiment that shows how Power
Pallet char removes Miracle Gro fertilizer from a concentrated solution.

The two bucket system is a syphon that takes liquid from the bottom of the upper bucket when the liquid added is above the sealed tube port (the orange band around the tube).
I built hygrometers from several gallon jugs, and bought a gallon of distilled water as a reference. The pictures show the comparison of the various jugs. The Miracle Gro solution was much heavier and the jug sank to the bottom of the lower bucket.
One can show that it is easy to tell when the char is fully charged with fertilizer by watching when the jug of distilled water floats higher than the reference band for pure water. This simple test will help define the value of char for use as a soil amendment.
