Compost Teas and Extracts

How are Compost Teas and Extracts Made?

Start by choosing high-quality compost that is well-aged and fully decomposed. This ensures that the compost is rich in beneficial microorganisms and nutrients.

Step 2: Preparing the Compost

Break up any large clumps of compost and remove any debris or large pieces that may hinder the extraction process.

Step 3: Brewing the Tea

There are two main methods for making compost teas and extracts: the passive method and the active method.

Passive Method:

In the passive method, place the compost in a porous bag or container and submerge it in a large container of water. Allow the compost to steep for a period of 24 to 48 hours, stirring occasionally to enhance aeration.

Active Method:

In the active method, add aeration to the brewing process to promote the growth of beneficial microorganisms. This can be done using an aquarium pump or an air stone to continuously bubble air through the compost tea mixture.

Step 4: Straining and Application

After the brewing period, strain the compost tea or extract to remove any solid particles. The resulting liquid can be applied directly to the soil around plants or used as a foliar spray.

Step 5: Storage

If not used immediately, compost teas and extracts should be stored in a cool, dark place to prevent the growth of harmful microorganisms. It is best to use them within a few days of brewing for maximum effectiveness.

Compost teas and extracts are valuable additions to any garden as they provide a concentrated source of beneficial microorganisms and nutrients. Regular application can improve soil health, enhance plant growth, and increase resistance to pests and diseases.
