Experiment looking at redox and clay at the seed-ball scale
« on: January 07, 2014, 06:54:24 PM »

Hi Good People,
I wanted to look into the claims that grey clay shouldn't be used for seed balls on the basis of redox state. Although this small experiment does not go into soil fertility issues, it does look into the color states of both iron-rich and iron poor clay as a small sample goes through redox changes. The link contains some background information, methods, pictures of the experiment in progress, and more detailed conclusions.

I used bokashi bran as the anaerobic microbe and also the food source (the electron donor.)

A summary of the results:
  • Red clay can undergo reduction in a short time.
  • Gray clay can be oxidized and stays gray.
  • Reduced clay at the seed ball scale is rapidly oxidized.
  • Because redox is a rapid process, one can probably anticipate some redox in the manufacture of seed balls using most methods and clays.

I am hoping to do more experiments that explore the optimization of seed balls, primarily with wild-type plants and single-species seed balls.
