We make compost tea from the worm castings from our vermiculture bins. We put 10 pounds of worm compost, a half cup of fish emulsion, 1/2 cup seaweed extract, and one cup of molasses in a 55 gallon drum of water from our tilapia tank. We add aerators and wait 24 hours. You can then put some of the tea on a slide and check under the microscope to see if it is teaming with microbial action. Then spray it on the vegetables, fruit trees and bare ground before planting. Once the tea is made it should be used within a few hours. It is a fungicide, deters some bugs and fertilizes the plants. It increases the microbial action in the soil and is an excellent foliar feed for any plant. Spray in the mornings before the sun hits the plants whenever possible.
Here is a formula for making compost tea in a five gallon bucket:
Put 4 cups of good fungus rich compost in a cloth paint strainer
add—1 tablespoon liquid seaweed
1 tablespoon hydrolysate fish
2 tablespoons molasses
1 teaspoon of a good sea salt for root vegetables
Fill the bucket with rain water or river water and aerate with an aquarium bubbler for 24 hours.
The best compost is worm compost, but if you have some good compost you can make it better. Take a pound of compost, add 1/4 pound of rolled oats, 1 tablespoon each of fish emulsion, seaweed extract, humic acid, and molasses. Moisten the mixture and let it sit for a week, mixing it every other day.
