Manure/compost teas have been used for centuries to enrich soil and boost plant health. Before synthetic fertilizers, farmers brewed nutrient-rich liquid amendments from manure, plants, and kitchen scraps to nourish their crops. These teas harness beneficial microbes, improve soil structure, and enhance nutrient absorption. Today, traditional manure teas remain a powerful tool for organic gardeners.

The History of Manure Teas

Long before modern liquid fertilizers, farmers relied on manure teas to feed their soil naturally. They steeped composted manure, plant matter, and food scraps in water, creating a microbial-rich solution to enhance plant growth. This practice allowed nutrients to be absorbed quickly by roots while fostering healthy soil biology. In contrast to chemical fertilizers that can deplete soil life over time, manure teas support long-term soil health and fertility.

Traditional Manure Tea vs. Modern Liquid Fertilizers

Modern fertilizers offer quick results, but they often lack the microbial diversity that manure teas provide. Here’s a comparison of the two:

While synthetic fertilizers provide instant nutrient boosts, they do not enhance microbial life or improve soil structure. Manure teas, on the other hand, create a balanced environment where plants can thrive naturally.

How to Make Traditional Manure Tea

Making manure tea is simple and requires just a few key ingredients. Here’s a step-by-step guide:

Ingredients:

• Composted manure (aged and free of contaminants)
• Non-chlorinated water (rainwater or dechlorinated tap water)
• Molasses or sugar (optional, to feed beneficial microbes)
• Aeration source (bucket and stirring stick or an aquarium pump for oxygenation)

Instructions:

1. Fill a bucket with 5 gallons of non-chlorinated water.
2. Add manure – About 2 cups of composted manure.
3. Stir or aerate – Stir occasionally or use an aquarium pump to keep it oxygenated.
4. Steep for 24-48 hours – Longer brewing increases microbial activity.
5. Strain and apply – Use cheesecloth or a fine mesh to remove solids, then apply the liquid to soil or as a foliar spray.

The Benefits of Manure Tea

Manure tea provides numerous advantages for soil and plant health. Below is a breakdown of its key benefits:

How to Use Manure Tea in Your Garden

• Soil Drench: Pour directly onto the soil to enrich microbial life and feed plant roots.
• Foliar Spray: Spray on leaves to introduce beneficial microbes and nutrients.
• Seed Soak: Soak seeds in manure tea before planting to promote strong germination.

Best Practices

• Use manure tea within 24 hours of brewing for the most active microbes.
• Apply in the morning or evening to prevent leaf burn.
• Avoid using anaerobic (foul-smelling) tea, as it may contain harmful bacteria.

The Takeaway: A Natural Boost for Your Garden

Manure teas offer a time-tested way to improve soil health and plant vitality. While synthetic fertilizers provide quick results, manure teas build long-term resilience, feeding plants while enhancing microbial diversity. By brewing and applying traditional manure teas, you can create a thriving, self-sustaining garden that flourishes season after season.
