BioChar Pot Trials -- Second Results (Even More Interesting!)

Two months ago we started these trials. (Link below.) Something very interesting is happening and although it's early days still, it seems obvious what it is -- most of these plants like charcoal in the soil. Up to a point, at least.

We're using soil straight from the field (together with charcoal in varying amounts) and OF COURSE we planted the same number of seeds at the same time in each pot.

There's actually not much in charcoal that's of benefit to plants -- but it is a very special vehicle for adding nutrients. These were added when we made the charcoal into biochar by soaking it in a nutrient-rich tea.

These results probably show how depleted the field soil is and how much it benefits from adding the nutrients. The difference in using biochar (instead of just nutrient tea) is that the biochar should be a much more permanent benefit to the soil. The soil structure is improved and the nutrients are retained within the structure of the charcoal so they shouldn't be washed out so readily.

This is a trial involving Perpetual (Cut-and-come-again) Beet, Radish, Grass, Tomatoes and Parsley. Other seeds types were sown but they were dropped from the trials because of poor germination. (Old seed? Seed didn't like the charcoal? A mixture of the two?)
