Worm Juice

Worm Juice is a broad term used to describe biological liquids derived from worm cast. Worms Downunder's Worm Juice (Worm Brew) is a concentrated liquid soil amendment used to regenerate soils for improved farming outcomes. DNA testing shows that our Worm Juice is abundant in beneficial bacterial and fungi with exceptionally high levels of disease-suppressive markers. These microbes reduce nutrient lockup in the soil, making more of what’s applied or already present usable to crops. Although Worm Juice is primarily a microbial amendment, the concentrate also contains some essential nutrients, plant growth promoters, hormones and enzymes which support critical biological and chemical processes. 

Worm Juice is an important part of the puzzle, particularly when incorporated alongside nutrition applications.

Mixing a nutrient source with your application such as urea, MAP, DAP, Super to Worm Juice kicks microbial activity into high gear. These microbes—bacteria and fungi—feed on the extra nutrients, multiplying faster and ramping up their work. For example, nitrogen-fixing bacteria convert more atmospheric N₂ into ammonium (NH₄⁺), while others turn urea’s nitrogen into plant-available nitrates (NO₃⁻) through nitrification.

Phosphorus-solubilising microbes release organic acids that dissolve bound phosphorus into phosphates (PO₄³⁻), ready for roots to take up. This process cuts nutrient lock-ups in the soil, making more of what’s applied or already present usable to crops. The result? Less money sitting in the soil, better nutrient cycling, and a soil system that delivers what plants need, when they need it.
