From Air to Acres: How Terreplenish Gives You Free Nitrogen and Lets You Cut Synthetic Fertilizer Without Cutting Yield

Nitrogen is the fuel that drives your crops. Without enough of it, plants stay small, pale, and low-yielding. For decades we’ve solved that problem with synthetic nitrogen fertilizer, the blue bags and liquid UAN we spread every spring. But prices keep climbing, and every heavy rain reminds us that a lot of that expensive N ends up in ditches, rivers, and eventually the Gulf of Mexico dead zone.
What if you could pull a big chunk of the nitrogen your crops need straight out of the air, for free, while also waking up the nitrogen that’s already sitting in your soil? That's exactly what a new generation of biological tools, led by Terreplenish, is letting farmers do.
First, the Nitrogen Basics (in plain English)
Nitrogen gas (N₂) makes up 78 % of the air we breathe, but plants can’t use it until it’s “fixed” into ammonium or nitrate forms they can absorb through their roots.
Nature has two main ways of doing this:
Symbiotic fixation - Legumes (soybeans, alfalfa, clover, hairy vetch) team up with Rhizobia bacteria in their roots and pull N₂ from the air.
Free-living fixation - Certain soil bacteria floating around in the root zone do the same job without needing a plant host.
Traditional organic sources like manure, compost, cover-crop residue, blood meal, and feather meal rely on soil microbes to break them down and release the nitrogen they contain. That’s good, but it still depends on having a healthy, active microbial population in the soil.
Synthetic fertilizer bypasses all of that… until the price goes up or the runoff becomes a problem.
Alternative Nitrogen Sources Farmers Already Use
Here are the most common ways growers are already reducing the synthetic bag:
Legume cover crops (hairy vetch, crimson clover, Austrian winter peas) can supply 50–150+ lbs N/acre when terminated at the right time.
Manure and compost - well-managed poultry litter or dairy manure can easily deliver 30-80 lbs available N per ton applied.
Crop residues - leaving corn stalks or wheat straw to decompose adds organic nitrogen that microbes slowly release.
Organic amendments - blood meal (12 % N), feather meal (13–15 % N), and alfalfa meal give a quicker shot of N.
These all work. But they still require good soil biology to unlock the nitrogen efficiently and that’s where many conventional soils fall short after years of tillage and high-salt fertilizers.
Enter Terreplenish: A Living Nitrogen Factory in a Jug
Terreplenish is a liquid microbial soil amendment packed with proprietary free-living nitrogen-fixing bacteria plus phosphate-solubilizing bacteria (PSB). Think of it as an “accelerated cover crop” you can spray or irrigate on in minutes instead of waiting a whole season.
Here’s the science in farmer terms:
These beneficial bacteria take N₂ straight out of the air and convert it into plant-available ammonium right in the root zone.
Independent third-party research shows 2 gallons per acre of Terreplenish delivers a 45–60 lb nitrogen credit per acre during a normal growing season.
The microbes start working immediately and multiply rapidly (from a few billion to trillions per acre within days), so the benefit builds as the season goes on.
It’s not magic, it’s just putting back the biology that healthy soils had before decades of intensive farming knocked it out.
How Terreplenish Reduces the Amount of Synthetic N You Need
Farmers using Terreplenish routinely cut their synthetic nitrogen rates by 30–50 % while maintaining or even increasing yield. Why?
You’re adding new nitrogen from the atmosphere instead of buying it in a bag.
The microbes improve overall nutrient uptake, so each pound of fertilizer you do apply goes farther.
Better root systems and higher soil organic matter mean less N is lost to leaching or volatilization.
Real-world results (validated on corn and over 100 other crops) show the product also frees up 15–20 lbs of legacy P₂O₅ per acre that was previously locked up in your soil. That’s extra nutrition you didn’t have to buy either.
Maximizing the Nitrogen Already Hiding in Your Soil
Your soil already contains tons of nitrogen, mostly tied up in organic matter, crop residue, and old manure. The problem is getting it into a form your crop can use before it leaches away or gets tied up again.
Terreplenish helps here in three practical ways:
Faster mineralization - The boosted microbial population breaks down organic matter quicker, turning stored organic N into ammonium and nitrate the plant can grab right now.
Better nutrient cycling - Healthier soil biology keeps the nitrogen cycle humming instead of letting it stall.
Improved soil structure and water holding - Terreplenish can increase water retention by up to 25 %, which reduces drought stress and keeps nitrogen in the root zone longer.
Farmers often report that after the first season the benefits compound: each year the soil biology gets stronger, and you need even less synthetic input.
How to Use Terreplenish on Your Farm (Simple Application Tips)
Rate: Most growers start with 2 gallons per acre (some go up to 2.5–3 on very depleted soils).
Timing: 7-10 days prior to planting or post germination through irrigation.
Compatibility: It works alongside conventional fertilizers, herbicides, and most other inputs (always do a small jar test).
Storage: Keep it out of direct sun and use within the season for maximum live microbes.
Tank Mixing: Once Product is mixed with water apply and use within 6hrs. DO NOT store after mixing.
It’s OMRI-listed and CDFA-registered for organic systems, so it fits both conventional and organic operations.
Local Power: Producing Your Own Terreplenish with EasyFEN from Easy Environmental Solutions
Even better news for farmers who want true independence from synthetic nitrogen bags is what’s happening beyond the jug at Easy Environmental Solutions. Their patent-pending EasyFEN™ system, a fully automated, modular “Fertilizer Plant in a Box” lets you turn local green waste into fresh Terreplenish right where you farm.
Here’s how the science works in plain terms: EasyFEN shreds crop residue, food scraps, or other biomass, presses out the plant juices, and then seeds that liquid with the same proprietary nitrogen-fixing and phosphate-solubilizing microbial blend that makes Terreplenish so effective. The microbes multiply rapidly in the nutrient-rich juice, creating a living, ready-to-apply fertilizer packed with the exact biology your soil needs. One compact unit (about half the size of a shipping container) can process up to 17,500 tons of local waste per year and produce more than 2 million gallons of Terreplenish, enough to treat over a million acres.
Because everything is designed and manufactured right here in the USA (with final assembly in Mankato, Minnesota), you get consistent quality, no overseas supply-chain headaches, and the peace of mind that comes with American engineering. Facilities in Wisconsin, Minnesota, and Florida already supply Terreplenish year-round, and EasyFEN units are rolling out to bring that same closed-loop system directly to co-ops, custom applicators, and larger farming operations.
This isn’t just another input, it’s a true circular system. You’re recycling nutrients that would otherwise be wasted, cutting transportation costs, creating local jobs, and lowering your overall fertilizer bill even further while rebuilding soil health for the long haul.
Bottom Line: Biology Is the New Fertilizer
You don’t have to choose between high yields and being a good steward of your land anymore. Terreplenish (and now EasyFEN local production) lets you tap into two powerful nitrogen sources at once:
Fresh nitrogen pulled from the air
The nitrogen you’ve already paid for that’s sitting in your soil
…and now you can make the product itself from the waste already on your farm or in your community.
Farmers who make the switch report lower input costs, stronger crops, better drought tolerance, and the satisfaction of knowing they’re rebuilding their soil instead of just feeding it for one season.
