Worm Castings Application Rate?

[Granite26]

I am thinking of putting a layer of worm castings on my growing space. I found a local source that sells by the ton.
Anyone have any good experience with application rates?
Thanks

In seed-starting mix, 1/4 to 1/3 produces nice seedlings. In the
soil, I do not know. The N-P-K is not very high. I remember advice
for container plants of 1/2 worm castings.

I would think you would treat it like a weak manure. Where I
might use a cup of Tomato-tone worked into the soil around
a plant, I would probably use a couple of gallons of horse,
rabbit, llama, or alpaca manure. I would put the worm castings
in the same class with the manures. Like rabbit, llama, and
alpaca manures, worm castings need no composting first,
but one should mix it up with the soil to get some air spaces
into it (so it does not become a solid clod like cow manure
when it dries).

Thanks for the thoughts!

Forget the tomato tone, the castings is all you will ever need. Use all you want they'll make more

I usually put a 2-3 cups of worm castings into a 2 gallon watering can and top off my tomato plants after I have given each of them a good watering. I don't know if it is exactly a proven method but my garden seems happy and my worms keep kicking out the castings!

I have a garden plot at a college. Several students have an experiment on the percentage of worm castings on the rate of tomato growth. I think the highest percent is 35. The plants are huge and have tons of tomato....but in that row every single tomato has blossom end rot. I can try to get all the percents, a few pictures of the plants and the variety name.

Out of curiosity, what price were you quoted for the ton? The stuff is so expensive by the bag.

$500/ton on sale for $250

That is a great deal!
