EM•1® Microbial Inoculant – Soil and Crop Support

The original. Manufactured in the USA by EMRO USA, the only authorized EM Technology® producer in the United States and Canada.

EM•1® is a concentrated liquid microbial inoculant that orchestrates the conditions for your soil's own microbial community to rebalance, regenerate, and thrive — restoring the biological equilibrium that healthy, productive soil depends on.

In practice, this translates to measurable outcomes: growers using the EM Nitro protocol have reduced nitrogen inputs by up to 50% while maintaining or improving yields — results demonstrated in field trials and full commercial scale operations in Brazil since 2015 and the United States since 2022, using authentic EM Technology®. Applied across corn, soybean, tomato, peanut, rice, barley, wheat, and other commercial crops, EM•1® supports stronger root development, accelerated organic matter breakdown, and the unlocking of nutrients already present in your soil — making fertilizer inputs go further and reducing dependence on herbicides, all within a regenerative, certified organic framework.
