Compost tea is a liquid solution or suspension made by steeping compost in water. It is used as both a fertilizer and in attempts to prevent plant diseases. Compost tea is made by steeping compost in water for a variable period (24-48 hours), then applying the liquid undiluted as a spray to plant parts, or as a soil-drench , such as to seedlings, or as a surface spray to reduce the amount of harmful bacteria and fungi on plants.
Step 1: Materials
There are two parts to the materials. The first group is to brew the tea, and the second set is to filter he tea for actual use.
1. Compost (I prefer to use organic manure compost, but any kind of compost will do)
2. Five gallon bucket, or any water-tight container
3. Unsulfered Molasses (This acts as food for the bacteria)
4. Air Pump
5. Hose for the air pump
For Filtering and use:
1. Another bucket
2. Wire mesh strainer
3. Cloth for filtering
Step 2: Mixing the tea
Fill the bucket about a third of the way with the compost. After you have done this, pour in some molasses, I just eyeballed the amount, but it was roughly 1/4 of a cup. Then simply add the water, you want to fill up the bucket nearly to the top. You can see the ring in the bucket from where I've used it before. The reason for this is because this is a fermentation process, there will be gas bubbles that will form on top of the water, and you don't want this to over flow. I would recommend that if you are on a city water system, that you get bottled water or at least filter the water somehow, because city water will have small amounts of chlorine and fluoride which at least make the process take longer and at worst kill the bacteria that you are trying to grow. Once you have everything in the bucket, give it a stir.
