Compost Tea Catalyst (15 Oz. Jar)

Formulated to promote diverse microbial activity, this compost tea catalyst is an essential additive for producing high-quality aerated compost tea. Its unique blend of seaweed extract, mineral powder, and select botanical ingredients works to nourish beneficial microorganisms without introducing simple sugars, which can encourage undesirable microbial growth. By fostering a balanced and thriving microbial community, it helps improve nutrient availability, soil structure, and plant health.

Suitable for use with all types of compost tea brewers, the catalyst is easy to incorporate into your brewing process. Simply add the recommended amount—7 tablespoons per 10 gallons of water—to your brewer and allow the microbes to multiply during aeration. Each 15 oz. jar treats up to 50 gallons of compost tea, making it a cost-effective choice for home gardeners, market growers, and small farms aiming to enrich their soil naturally.

Compost tea produced with this catalyst can be applied as a soil drench to boost root zone activity or as a foliar spray to introduce beneficial organisms directly to plant surfaces. By integrating this additive into your compost tea program, you can enhance plant resilience, promote healthy growth, and reduce reliance on synthetic fertilizers.
