Gardening enthusiasts and sustainable growers have long recognized the benefits of compost as a natural soil conditioner. But what if you could supercharge those benefits and create a liquid elixir that provides your plants with an extra boost of nutrition and protection? Enter compost tea—a nutrient-rich liquid solution that can work wonders in your garden. In this article, we'll explore how to make compost tea, the importance of keeping it aerobic, and why microscope testing post-creation is crucial for ensuring its effectiveness.
What is Compost Tea?
Compost tea is a liquid fertilizer and soil conditioner brewed from well-aged compost with the appropriate levels of aerobic biology. It contains the beneficial microorganisms, nutrients, and organic matter found in compost, but in a more concentrated form. This concoction enhances soil fertility, encourages healthy plant growth, and helps ward off pests and diseases. Compost Tea brew is more specifically designed for all the above ground parts of a plant.
The Recipe: Brewing Compost Tea:
Ingredients:
- Well-aged compost
- Water
- Microbial food to feed the organisms and get them to rapidly multiply
- Aeration system (e.g., air pump and diffuser stone)
- Container with a lid (5-gallon bucket or larger)
- Cheesecloth or mesh bag
Steps:
1. Compost Selection: Choose high-quality , well-aged compost free from contaminants or pathogens such as MBG BioBalanced Compost. Roughly fill a mesh bag or cheesecloth with compost, leaving enough room for the compost to expand when wet.
2. Water and Molasses: Fill the container with water, leaving some space at the top. For every 5 gallons of water, add 1-2 tablespoons of unsulfured molasses. Molasses provides a food source for beneficial microorganisms.
3. Aeration: Attach the air pump and diffuser stone to ensure a constant flow of oxygen. Compost tea needs to be well-aerated to maintain an aerobic environment.
4. Brewing Time: Allow the compost tea to brew for 24 hours. Brew time is directly related to ambient temperature, organism growth and available oxygen in the solution. As the oxygen continues to run out over time, the microbial diversity begins to favor anaerobic organisms. Maintain a temperature of 60-80°F (15-27°C) during brewing helps keep anaerobes from growing rapidly.
5. Straining: Remove the compost bag from the tea, squeezing out any excess liquid. The remaining compost can be added to your compost pile.
6. Testing: Making sure you test your compost tea brew is critical to knowing what you actually brewed in your tank. With regular microscope scanning you can be sure you are only applying "good guy" biology.
7. Application: Dilute the brewed compost tea with water (usually 10:1) before applying it to your garden. Use a watering can or a sprayer to distribute the tea evenly.
Aerobic Compost Tea: The Key to Success:
Keeping the compost tea aerobic (oxygen-rich) throughout the brewing process is essential. Aerobic conditions favor the growth of beneficial microorganisms while discouraging harmful pathogens. Aerated compost tea is teeming with life, making it more effective at enhancing soil health and promoting plant growth.
Microscope Testing Post-Creation: Ensuring Quality:
After brewing compost tea, it's critical to examine it under a microscope to assess its microbial diversity and health. A microscope test can reveal the presence of beneficial bacteria, fungi, and protozoa while highlighting any potential issues, such as an imbalance or the presence of harmful organisms. This test can guide adjustments to your brewing process and ensure the effectiveness of the tea.
Compost tea is a valuable tool in sustainable gardening, providing your plants with essential nutrients and fostering soil health. By following a well-aerated brewing process and conducting microscope testing post-creation, you can harness the full potential of compost tea and watch your garden flourish with vitality and resilience.
