How Natural Farming Heals the Land, Air, and Sea

What Conventional Farming Costs

Conventional farming feeds the world. It also damages it in ways the world is now reckoning with.

Conventional farming emits roughly 10–12% of all global greenhouse gases. It's the leading cause of nutrient pollution in U.S. waterways, the driver of more than 500 dead zones in coastal seas worldwide, and the practice that's stripped an estimated 50–70% of the original organic carbon from agricultural soils since cultivation began. Most of this isn't a single villain. It's the cumulative cost of synthetic fertilizers, synthetic pesticides, the heavy machinery that spreads them, and the tilled, simplified soil they leave behind.

There's a better way. Korean Natural Farming doesn't carry most of those costs — it can't, by design. KNF doesn't use synthetic fertilizers. It doesn't use pesticides or herbicides. It doesn't till in the conventional sense. It doesn't ship inputs in from anywhere. Everything KNF needs to grow plants and animals comes from biology either collected on-site or fermented on-site.

This article is about what that means, environmentally. Three sections, three different parts of the planet: what KNF doesn't put into the air, what it doesn't put into the water, and what it actively puts back into the soil.

1. Smokestacks Hidden in a Bag of Fertilizer

You don't see smokestacks on a farm. But behind every conventional farm — whether it's a small family operation or an industrial mega-farm — smokestacks are running, pumping greenhouse gases at different stages of growing the crop. Most people don't realize they're there, because some of them are hundreds of miles away from the field.

One smokestack is making the fertilizer. Manufacturing synthetic nitrogen fertilizer is one of the most energy-intensive industrial processes humans have ever invented — it pulls nitrogen out of the air and binds it into ammonia at very high pressure and temperature, running on natural gas. Globally, this process consumes about 1–2% of all the energy humanity uses and produces roughly 1.4% of all human CO₂ emissions. That's before a single pound of fertilizer leaves the factory door.

Another smokestack fires up when the fertilizer hits the field. Soil microbes don't always cleanly convert nitrogen fertilizer into plant food. A portion of it leaks back out as nitrous oxide (N₂O) — a greenhouse gas roughly 265–298 times more potent than CO₂ over a 100-year period. Agricultural soils are the single largest source of human-caused N₂O on the planet, accounting for about half of all of it from human activity.

And the math gets ugly fast. The relationship between fertilizer applied and N₂O released isn't linear — it's exponential. Apply twice as much nitrogen as crops can use, and you don't get twice the N₂O. You get something more like four or five times. Every pound past what the crop can use leaks more greenhouse gas than the pound before it. (Shcherbak et al. in PNAS.)

There's a quieter side effect, too. A 2026 study showed that N₂O isn't just bad for the climate — it's directly toxic to many soil bacteria. Specifically, the bacteria that rely on vitamin B12 to make a key amino acid called methionine: N₂O hijacks the enzyme they need, and growth stalls. By the researchers' estimate, about 30% of the bacterial species we've studied closely rely solely on that B12-dependent enzyme — making them potentially vulnerable. The same gas heating the planet is damaging the microbiology farmers need for healthy soil. Chemical farming, in a quiet way, undermines its own foundation. (Wasson & McRose in mBio.)

And there's the smokestack of working the field itself: diesel for tractors and combines, fuel for tilling, energy for pesticide and herbicide manufacturing, fuel for the trucks and trains hauling bagged inputs across continents. Each piece is smaller than the others on its own. But it adds up.

What KNF Skips

KNF skips them all.

Because there's no synthetic fertilizer in the system, there's no energy demand to manufacture it and no emissions from shipping it. KNF replaces synthetic nitrogen with biological inputs — FAA, FPJ, and IMO — plus biological nitrogen-fixation in healthy soil. These inputs are made in small batches on the farm, applied at low concentrations (typically diluted 1:500 to 1:1000), and consumed quickly by soil biology.

That last point matters. A 2024 study found that organic fertilization actively reduces N₂O emissions — by encouraging soil microbes to convert N₂O into harmless N₂ gas (a process called the denitrification cycle). So it's not just that KNF emits less than conventional. The biological inputs actively shift soil microbes toward capturing and neutralizing N₂O before it can escape. (Tang et al. in Science of the Total Environment.)

Beyond fertilizer: no pesticide or herbicide manufacturing. Minimal mechanization — a hand sprayer or water sprinklers do most of the work at small and mid scale. No-till practice eliminates the most fuel-intensive field operation. And every input is made on-farm or sourced locally — no transcontinental shipping of bagged anything.

2. Where Fertilizer Goes When It Rains

Rain doesn't care that the fertilizer was meant for the corn. When water moves, what's on the soil moves with it — off the field, into the next field, into the creek, into the river, eventually into the ocean. Some of the nitrogen volatilizes back into the air. Some leaches down into groundwater. Most of it washes downstream.

The downstream consequences pile up.

The chain of events is well documented. Excess nitrogen and phosphorus reach waterways and trigger runaway algal growth (eutrophication). When the algae die and decompose, they consume the dissolved oxygen in the water. What's left is a low-oxygen "dead zone" where fish and shellfish can't survive. (EPA.)

There are now more than 500 of these dead zones globally. The most famous in U.S. waters is in the Gulf of Mexico, fed by runoff carried down the Mississippi River from the Corn Belt. In 2017, the Gulf dead zone reached 8,776 square miles at its peak — bigger than the entire state of New Jersey, and the largest ever measured. Roughly three-quarters of the nitrogen driving that dead zone comes from agricultural runoff. The corn crop is feeding cattle in Iowa, and the runoff is killing crabs in Louisiana. (NOAA.)

The damage doesn't stop at the surface. Nitrates from synthetic nitrogen fertilizer are the most widespread groundwater contaminant in U.S. farming regions. High-nitrate drinking water is linked to "blue baby syndrome" in infants (a rare but serious oxygen-delivery problem called methemoglobinemia) and to elevated cancer risk over long-term exposure. Pesticide residues show up consistently in streams and groundwater across major agricultural regions, too — often at levels that harm aquatic life well before they reach human safety thresholds.

Nothing Harmful to Run Off

KNF uses no synthetic nitrogen, no synthetic phosphorus, no pesticides, and no herbicides. There is nothing harmful to run off.

That's the simple version. The slightly less simple version: the inputs KNF does use — indigenous microorganisms (IMO), fermented plant juice (FPJ), fish amino acid (FAA), lactic acid bacteria (LAB) — are biological materials, applied at low concentrations, and rapidly consumed by soil biology. They don't accumulate. They don't leach. They don't sit in soil for months waiting to wash downstream.

KNF practice also actively reduces erosion and changes how water moves through soil. No-till preserves soil structure, which means rain infiltrates the ground instead of running across the surface. Soil rich in microbial life holds together better when wet, instead of breaking apart and washing away. And standard KNF practice involves keeping the ground covered year-round with mulch or cover crops, slowing water movement and preventing sediment from reaching streams.

For a farm operating downstream of conventional neighbors, that's a defense against contaminants flowing in. For the broader watershed, widespread adoption of biological farming would dramatically reduce the nutrient loading that creates dead zones and the pesticide load that contaminates drinking water.

3. Putting Carbon Back in the Ground

So far we've covered what KNF doesn't put into the atmosphere or the water. The third part of the environmental ledger is more active. Healthy soil is the largest carbon sink on land — and farms can either feed that sink or drain it. KNF feeds it.

How Conventional Farming Bleeds Carbon

Globally, agricultural soils have lost an estimated 50–70% of their original organic carbon since first being plowed. Three things drove the loss. Tillage exposes soil organic matter to oxygen, accelerating its decomposition into CO₂ — basically, plowing breathes carbon out of the ground. Synthetic nitrogen feeds plants directly, which means soil microbes that would otherwise be cycling organic matter and building humus go quiet for lack of work. And monoculture narrows the diversity of root exudates that feed diverse microbial communities, leaving simpler, less resilient soil that doesn't stabilize carbon as effectively.

Over the last century of industrial agriculture, the net effect has been a slow bleeding of carbon from soils into the atmosphere. The 10–12% global greenhouse-gas footprint we mentioned at the top isn't just smokestacks — soil carbon escaping as CO₂ is one of the biggest pieces of it.

What the Research Shows

When farms switch away from chemical-intensive management, soil starts banking carbon again. The basic picture across the research is clear: organic and biological systems gain carbon, conventional systems don't. A 2012 meta-analysis of 74 studies found organic systems hold about 3.5 metric tons more carbon per hectare in their topsoil and add an extra 0.45 metric tons per year on top of that (Gattinger et al. in PNAS). An earlier study found organic systems gain about 2.2% in soil carbon per year after conversion, while conventional systems show no change — and most of that gain traces to organic-fertilizer use, the kind of input KNF supplies in abundance through IMO, FPJ, FAA, biochar, and compost. (Leifeld & Fuhrer in Ambio.)

The specific practices that work are the ones that build soil biology. A 2023 review of 345 measurements across seven regenerative practices — agroforestry, cover crops, no-till, animal integration, biological inputs, and others — found all seven boost soil carbon, and combining them stacks the benefit. A 2025 review of 147 Indian studies ranked the practices: biochar gives the biggest gains, followed by farmyard manure, green manure, and compost. KNF sits squarely inside this regenerative-agriculture family — biochar, biological inputs, no-till, mulch, and crop rotation are all standard KNF practice, and the underlying philosophy of feeding soil biology rather than feeding the plant directly is the same. (Villat & Nicholas in Frontiers in Sustainable Food Systems; Patil et al. in Scientific Reports.)

The longest-running evidence comes from the Rodale Institute's Farming Systems Trial in Pennsylvania, which has been running side-by-side organic and conventional plots since 1981. Their data: organic plots with composted manure and crop rotation sequester more than 2 metric tons of carbon per hectare per year — about 1,800 pounds per acre — while the paired conventional plots actually lose carbon. Trials in Egypt, Iran, and Thailand have measured even higher sequestration rates, in the 4–6 metric ton range. (Rodale Institute.)

The strongest effects, across all of these studies, show up after five-plus years of consistent practice. Soil-building is a long game.

Soil as a Savings Account

Think of healthy soil as a carbon savings account. The soil microbes are the tellers. They take fresh deposits — root exudates, dead leaves, decomposing organic matter, the manure you spread — and convert them into long-lived storage compounds (humus, glomalin, microbial necromass). Some of those deposits stick around for decades. Some for centuries. The bigger and more diverse the staff at the soil bank, the faster the deposits get filed and the longer they stay locked in the vault.

So how big is the staff? A 2017 meta-analysis found that organic farming systems have 32% to 84% greater microbial biomass than conventional, depending on which measure you use — across 56 studies and 149 pairwise comparisons spanning multiple climate zones. The enzyme activity gains are even larger. KNF, with its targeted indigenous-microorganism inoculation and biological feeding regime, is built specifically to accelerate this kind of microbial recovery beyond what typical organic practice achieves. (Lori et al. in PLOS ONE.)

The Honest Picture

Korean Natural Farming, as we practice it at Mountain View Farms, doesn't burn natural gas to make our fertilizer. It doesn't put nitrate into the aquifer beneath us or pesticides into the streams flowing past us. It doesn't compact and bleed soil carbon into the atmosphere. It's a system that runs on biology — collected, fermented, and applied locally — and biology is the original carbon-cycling system on Earth.

Conventional agriculture has fed the world for a century. It's also damaged it in ways the world is now reckoning with. Natural farming is one of the proven ways back.
