Liquid Biological Amendments (LBAs)

Compost teas and compost extracts are liquid biological amendments rich in a diverse and abundant community of living soil microbes. When applied to soil or plants, these microbes help rewild degraded soils by re-introducing the full soil food web—restoring soil structure, improving nutrient cycling, and supporting healthier, more resilient plants.

• Compost Extracts

Compost extracts are produced by gently washing high-quality, biologically complete compost with water to transfer the microbial community into solution. The resulting extract closely mirrors the biology of the source compost.

Compost extracts can be applied as a soil drench, sprayed on the soil surface, or deep-root injected into the root zone of trees and perennial plants.

• Compost Teas

Compost teas are made by actively aerating a compost extract while adding targeted microbial foods. This brewing process allows microbes—particularly bacteria—to reproduce and increase in concentration.

Compost teas are typically bacterial-dominant and, due to their naturally sticky biology, are especially well-suited for foliar applications and plant surface treatments.

​

We have three LBAs that are designed to match the successional stage of your plants.

 

1. Early Succession Tea: bacterial dominant for turf + annuals, made using bacterial-dominant thermal aerobic + vermicompost blend

2. Mid Succession Extract: increased fungi, protozoa and nematodes for vegetables + crops, made using our biologically complete thermal aerobic compost

3. Late Succession Extract: fungal dominant, for shrubs and trees, made using our well-aged Johnson-Su and other fungal-dominant composts ​​​

​

All LBAs are made using the microscope to check quality and ensure a concentration that allows the product to be applied at 10gal/acre.
