Wouldn't it be sweet if we could sieve our experiences here and harvest some facts ?
Tho I seem to swim upstream in digging for facts, I've gleaned a few, I think. I think there is something like consensus on all fronts, that vermicompost and vermicompost tea are good for plants and good for soil, and better than "synthetic" fertilizers in a long-term healthy -earth sense. The G. Profs seem to object more to the claims of disease prevention, than to the idea that VC is good for gardens. There are a variety of views on whether Tea is worth the work, and if so, what's the recipe that is worth the work and what are its best uses ? Further, what is the value of aerating ?
I challenge the sharp divide between Leachate and Tea because I think the facts depend on some variables.
What if the liquified (pureed food) I feed the worms filters through castings present ? At one extreme would be liquid from rotting stuff that worms have not processed; at the other extreme could be liquid that washed through mostly castings with little or no unprocessed stuff,
Without knowing the science of the desirable bacteria, I don't know what the value of aerating is. I can speculate that since it is fact that the bacteria that exist in nature in the top 3 ? inches of hypothetically healthy soil are aerobic, that aerating the liquids may have merit.
Today I sprayed my disease-prone roses with some undiluted, well aerated God Knows What: part stale "Tea" part leachate.
It was hot and sunny: the spray visibly coated the young leaves.. If the leaves are healthier this year than last, I'm going to give the treatment credit. (I don't use conventional treatments anymore for fear of harm to bees.)
If anyone has suggestions on how to test VC on Tomatoes, I haven't found them yet. We do wander among our threads.
I could make tea with chicken manure or cow manure but we know that the chicken stuff is high nitrogren and that wouldn't address the question. Nor does comparing Tea or VC to Miracle Gro address the question. I assume (I've never used it but my neighbors do) that Miracle Gro for tomatoes would be more productive and maybe safer food.
Do you disagree ?
How would I test Tea ? Aerated or Not ? vs What ? vs mixing the castings into the growing medium ? In what ratios ?
I think many of the tomatoes will be determinates in pots, the long-term health of the garden is less an issue.
The bed that will get the Brandywine even has charcoal in it and a little human nitrogen. No science there just Overdo the whole way.
