Compost Tea

What is compost tea?

Compost tea is a fermented liquid solution made from mature compost, rich in beneficial microorganisms such as bacteria, fungi, actinobacteria, and protozoa. When applied to the growing medium or as a foliar spray, it provides a rich microbial diversity that strengthens the plant's immune system and significantly improves soil structure and health.

It is a key tool in organic farming, permaculture, and regenerative agriculture, which seeks to promote natural processes instead of using chemicals.

How do you use compost tea?

It can be applied directly to the substrate through irrigation or sprayed onto the leaves. In both cases, the goal is to colonize the rhizosphere and plant surfaces with beneficial microorganisms that help the plant feed better and defend itself against pathogens.

It can be prepared at home by aerating compost with water and sugars (such as molasses) for about 24-48 hours, or with kits and prepared extracts like those offered by Alchimia, which simplify the process and guarantee a high microbial load.

Who is this product ideal for?

This biostimulant is perfect for organic growers who want to:

• Revitalize the substrate without resorting to synthetic fertilizers
• Improve soil structure and nutrient retention capacity
• Boost root health and natural plant resistance
• Promote a living and balanced ecosystem in your cultivation
• It is also ideal for regenerative crops, certified organic crops, or for those who reuse the substrate after several harvests.

What are the benefits of compost tea?

Regular use of compost tea helps maintain a living, active, and balanced soil. It helps reduce the use of external inputs, increases nutrient absorption efficiency, and improves the biological quality of the crop. It also promotes greater microbial biodiversity, which translates into healthier, more vigorous, and stress-resistant plants.

What types of products can you find in this category?

At Alchimia, you will find:

• Complete kits for preparing aerated compost tea
• Ready-to-use microbial extracts
• Additives such as molasses or specific microorganisms to enrich the mixture
• Fertilizers compatible with microbial life

All of them were selected to ensure sustainable and effective cultivation, with the lowest possible environmental impact.

Frequently Asked Questions About Compost Tea

What is the difference between compost tea and compost extract?

Compost extract is obtained without aeration and contains fewer active microbes. Compost tea, when fermented with oxygen, develops a higher microbial load and is more effective as a biological inoculant.

Can compost tea be combined with liquid fertilizers?

Yes, as long as you use organic, microorganism-friendly products. It's recommended to avoid fungicides or chemicals that could harm the tea's microbes.
