Compost tea recipe for soil drench
Just made my first batch of compost tea (5-gallon brew) for a soil drench for my NC red clay. The tea brewed up fine and dandy, but as an undiluted soil drench it only covered a fraction of my yard (1/2 acre). So now I'm ready to increase production to 15 gallons of brew, but I wanna make sure my recipe will scale properly.
Here's the tea recipe:
a) "wiggle worm" worm castings - 1 lb.
b) Fish hydrolysate - 1/2oz. per gallon
c) Humate concentrate - 1/2oz per gallon
Obviously, I know how to scale parts b) and c), but do I need 3 times the amount of worm castings to go from a 5-gallon brew to a 15-gallon brew?
BTW, many thanks to David Hall for his web site that hosts the Deuley's Little Texas Tea Brewer instructions. Great site and great brewer instructions.
