With you there, on the small amount of compost, Kurt. I have no lawn so really can't produce any volume of compost, so I do make 'tea' out of what I get. I'd have to water a section of the same type of plant with the tea, and with 'other' stuff to see if there's a difference. Hm, I do have one bed with Heliconias in it that I could try that on.
It's very hard to document any results though, since it varies from batch to batch for everyone. It depends what you've composted, how much you put in your brew, the time of year, temperature as the breakdown occurs, quality and pH of your water etc. All that will determine what's in your tea.
