Making liquid organic fertilizer or compost tea for vegetable gardens is done by using compost or well-composted animal manure to make a tea that is applied to the soil around vegetable plants. Liquid organic fertilizer or compost tea provides an immediate source of nitrogen and trace minerals to the plants and surrounding soil. If used as a foliar feed, the tea should be diluted with water until the liquid organic fertilizer is the color of weak tea.
How to Make Liquid Organic Fertilizer for Vegetable Gardens
Place 2 shovelfuls of well-composted manure or compost into a burlap bag. Tie or secure the end of bag so the compost cannot spill out.
Fill a bucket or container that holds 5 gallons of water three-fourths full of water.
Submerge the burlap bag holding compost into the bucket or container of water.
Leave the burlap bag containing compost in the container holding the water for two weeks, adding water as needed to prevent the water level from getting low from evaporation. Locate the bucket or container in an area where the smell will not become offensive to anyone because the fermentation process will produce a strong odor of rotting organisms.
Remove the burlap bag from the container holding the water after two weeks and dispose of burlap bag contents by adding them to the compost pile. Apply finished liquid organic fertilizer or compost tea to soil around vegetable plants.
