EM® Nitro Protocol
Want the complete EM® Nitro Protocol for your crop and operation? Contact our technical team — full implementation guidance, including safety documentation, is provided directly to commercial customers.
Nitrogen management is one of the most significant cost and efficiency challenges in commercial agriculture. EMRO USA developed the EM® Nitro Protocol — a nitrogen-management program built around EM•1® Microbial Inoculant — to give growers a biologically-based approach to nitrogen-management planning.
This page explains the concept behind the program, what our field trial and commercial implementation data shows, and which crops growers have used it on. The complete protocol — preparation steps, dosing, safety documentation, and crop-specific timing — is provided directly to commercial customers working with our technical team, not published here. Contact us to request it.
Understanding Nitrogen Loss in Conventional Programs
When nitrogen fertilizers are applied to soil — whether as urea, anhydrous ammonia, or liquid nitrogen — the plant does not absorb them immediately. Nitrogen typically needs to convert through biological processes before plants can use it, and during that window, losses can occur through several well-documented pathways:
- Volatilization — nitrogen escaping into the atmosphere as ammonia gas, particularly in warm, dry, or alkaline soil conditions
- Leaching — nitrate nitrogen moving below the root zone with rainfall or irrigation
- Denitrification — nitrogen converted to gas by soil microorganisms in saturated or poorly aerated soils
- Immobilization — nitrogen temporarily locked up by soil microorganisms
The extent of these losses varies significantly by crop, soil type, climate, and application method — agronomic research on nitrogen use efficiency generally points to a wide range of recovery rates rather than a single fixed figure. This variability is the starting point for how EMRO USA approaches nitrogen-management planning with growers.
The EM® Nitro Approach
The EM® Nitro Protocol is designed around a fermentation-based approach to nitrogen management, using EM•1® Activated (Activated EM®) as the biological driver. The general concept: nitrogen is processed through a fermentation step before field application, with the goal of integrating fermentation processes into overall nitrogen-management planning.
The complete preparation process — including ingredient sourcing, sequencing, timing, and required safety procedures — is technical and crop-specific. Because it involves a fermentation process, it requires proper safety protocols and is provided only as part of direct technical support from our team, not as a general public instruction set. Contact us to discuss what's involved for your operation.
Field Trials & Commercial Results
EMRO USA's nitrogen-management approach has been evaluated through field trials in Brazil beginning in 2015, and through commercial-scale implementation in the United States beginning in 2022. Trial and commercial participants have implemented a range of nitrogen-management strategies using the EM® Nitro Protocol, with outcomes varying substantially based on crop, soil conditions, climate, and management practices.
What this means in practice
We do not present a single expected outcome for every grower. Our technical team works with you to evaluate your specific crop, soil, and current nitrogen program, and to set realistic expectations based on comparable trial and commercial data.
Outcomes discussed with our technical team may include grower-reported and trial-observed results from EMRO USA's Brazil field trial program (since 2015) and U.S. commercial implementations (since 2022). Individual results vary; ask our technical team for documentation relevant to your crop and region.
Crops Growers Have Used the Program On

Certified Organic Operations
A note on organic compliance
EM•1® is OMRI Listed® for specified uses in organic production. The EM® Nitro Protocol involves additional ingredients and an on-farm preparation process — certified organic growers should verify every component of the protocol, including all ingredients and preparation steps, with their certifying agent before use. OMRI listing applies to EM•1® specifically, not to the protocol as a whole.
"Our technical team works directly with growers to evaluate fit, set realistic expectations, and provide the data relevant to their specific crop and region — not a one-size-fits-all promise."
Frequently Asked Questions
Does the EM® Nitro Protocol work for certified organic operations?
EM•1® is OMRI Listed® for specified uses in organic production. Other protocol components are also naturally derived, but growers in certified organic operations should verify every input and preparation step with their certifying agent before use, as requirements vary by certification body.
How is the protocol typically implemented?
This varies by operation. EMRO USA generally recommends a phased approach, particularly for growers new to biological input programs — our technical team will work with you to set a season-by-season plan based on your crop, soil, and risk tolerance, informed by our trial and commercial data.
Is this compatible with our existing fertilizer program?
The EM® Nitro Protocol is generally designed to work alongside existing fertilizer programs rather than as a complete first-season overhaul. Contact our technical team to discuss compatibility with your specific equipment and program.
What is Activated EM® and how is it different from EM•1®?
EM•1® is the base product. Activated EM® (AEM) is produced by fermenting EM•1® with other natural ingredients over a controlled period. The EM® Nitro Protocol uses AEM as part of its process. Complete preparation instructions are provided directly to customers, along with required safety documentation.
Can I get the protocol without purchasing EM•1® first?
The complete protocol is provided to commercial customers and distribution partners as part of their relationship with EMRO USA. Contact us to discuss your operation.
