Activated Compost is an OMRI Listed, plant-based compost which has gone through a Secondary Activation Phase. In this stage organically approved ingredients are added at a specific time, resulting in a unique bio-catalytic effect, where microbial life flourishes. Nutrients are metabolized by microbes in the compost and are more readily available to your plants. Purple Cow Activated Compost makes nutrients more available for plant uptake, and is an ideal amendment to improve soil and growing media.

OMRI Certificate

General Use Recommendations

  • 1-2 tons per acre for broad acre applications (more for diversified vegetable production and hoop houses)

  • Activated is an ideal soil amendment for conventional, transitioning, and certified organic land
