Agriculture — Open Field

Roots go as deep as the oxygen does.

Compacted, salt-loaded, oxygen-poor ground caps your root system in the top few inches — and everything downstream of that is capped with it. We put oxygen into your irrigation water as ultrafine bubbles, so roots grow deeper and finer, aerobic soil biology rebuilds structure, and the fertilizer you already bought meets a root system that can take it up.

The Problem

The root system you have can't reach what you bought

Compaction and salt loading close the pore network. Water sits, oxygen doesn't move, and roots stay shallow because there is nothing to grow into. In that same low-oxygen ground, the aerobic microbes that bind particles into aggregates and cycle nitrogen slow down, while the anaerobic pathways that denitrify your fertilizer and release nitrous oxide speed up. So you apply more and absorb less, season after season. You're not under-fertilizing. You're under-absorbing — and the reason is a root system that had nowhere to go.

The Solution

Oxygen down the drip line. Root and biology do the rest.

Our injectors put oxygen into irrigation water as ultrafine bubbles — small enough to stay suspended and travel with the water into the soil profile instead of surfacing at the emitter. Oxygen arriving in the root zone does two things at once. Roots respire, elongate and branch, so the system goes deeper and finer. And the aerobic soil microbes that aggregate particles and cycle nutrients get the conditions they need: in published trials, total porosity rose 43% and pore connectivity by more than 355% — soil biology rebuilding structure, not a tillage pass. Water then moves, salts leach below the root zone instead of concentrating in it, and what you apply meets a root system able to take it up.

Key benefits

Deeper, finer root systems

A root only grows into ground it can respire in. Oxygen arriving with the irrigation water lets roots elongate and branch past the compacted layer instead of mounding above it — more absorptive surface, more of the soil profile in play, and a plant that isn't living off the top four inches.

Soil biology that rebuilds structure

Soil structure is built by aerobic microbes gluing particles into stable aggregates. Starve them of oxygen and structure degrades every season no matter how you till. In published research, oxygenated irrigation raised total porosity 43% and pore connectivity by more than 355% — the biology doing work a tillage pass can only imitate for a few weeks.

Stop paying for fertilizer the root can't reach

In published trials, growers held the same yield on roughly 20–25% less fertilizer. Read that precisely: those trials hold the harvest constant and ask how far the input can fall. It is the same physical gain taken one way rather than two — a lower input rate or a bigger harvest, not both added together. How much of it your ground can take depends on how far above the crop's real requirement your program already sits.

Drought resilience built from root architecture

Deeper, denser root systems reach moisture shallow ones can't. When the heat arrives or the rain stops, the crop holds longer — not because the water changed, but because the plant spent the earlier part of the season building the architecture to survive it.

Salt moves down, not into the root zone

Salt concentrates where water stops moving. Restore pore connectivity and irrigation carries sodium below the root zone instead of stacking it in the exact layer your roots occupy — which is the difference between leaching salt and simply relocating it a few inches. This is leaching through the soil profile, not water desalination.

Faster, more uniform stands

Early root development is the part of the season most exposed to low oxygen — the seedling has no root system to buffer with yet. In published research, oxygenated water improved germination 15–25% with markedly more uniform emergence: fewer gaps, less replanting, and a stand that closes canopy ahead of the weeds.

Proof

Measured on customer ground

Two named sites, our own instruments, and the conditions each number was taken under. Single sites under their own soil and water — demonstrated there, not promised here.

-35.4% salt compaction

Compacted salts in the treated root zone fell 35.4% against untreated control greens on the same course, on the same irrigation schedule.

+24.7% water penetration

Water moved into the profile instead of pooling at the surface — the same water, reaching depth. Measured on the treated green over the same pilot.

+300% dissolved oxygen

Dissolved oxygen in the treated irrigation water, against the untreated feed. This is the input the other two figures came from, not a third result.

2.3× stem growth rate

Stem growth went from 0.035 to 0.08 mm/day on treated blocks. A growth rate measured in season — not a harvest figure, and not a yield.

Research & hardware

What the research says, and what we build

Each problem below is paired with the published work on it and with the hardware that puts the mechanism in your line. Figures are other people's trials unless marked KST field data.

Figures below are from independent, peer-reviewed studies unless marked KST field data.

Problem: Your roots stop where the oxygen stops

The Problem: Heavy clay and years of irrigation have pushed air out of the root zone. A root can only grow into ground it can respire in, so the system plateaus in the top few inches and everything downstream of root depth plateaus with it — water access, nutrient access, standing power in a dry August. It is worst in compacted or over-irrigated fields. Bhattarai et al., 2005

What We Do: We inject oxygen as ultrafine bubbles directly into your drip lines. They are small enough to stay suspended and travel with the water into the profile rather than surfacing at the emitter, so oxygen arrives where roots are actually working. In published field trials on degraded clay soils, this approach raised lettuce yield substantially — their soils, their crop, and a ceiling on how far the result transfers to yours.

Problem: Your soil biology can't rebuild structure without oxygen

The Problem: Soil structure is not a mechanical property you can till into existence and keep — it is built and maintained by aerobic microbes binding particles into stable aggregates. Starve that community of oxygen and structure degrades every season regardless of the pass you make. Compaction blocks water; blocked water blocks oxygen; low oxygen slows the organisms that would have fixed the compaction. The loop closes on itself.

What We Do: Oxygenated irrigation breaks the loop at the point it is cheapest to break — the water you are already applying. Aerobic microbial activity picks back up, aggregation resumes, and the pore network reopens. In published trials, total porosity rose 43% and pore connectivity by more than 355%, so water and roots can move again. This is biology rebuilding structure over seasons, not an overnight change in soil texture.

Problem: You're paying for fertilizer that does not arrive

The Problem: A large share of applied nitrogen is lost — washed away or locked up — before roots can take it up. Two things drive it, and both trace back to oxygen: a shallow root system has less surface in contact with the fertilized zone, and low-oxygen soil favors denitrifying pathways that convert your nitrogen to gas before the crop ever sees it. So the answer looks like more fertilizer, and more fertilizer feeds the same losses.

What We Do: We raise the oxygen in the root zone, which grows more root to absorb with and shifts soil microbial activity away from the denitrifying pathways. The negative surface charge on ultrafine bubbles also helps carry cations like potassium and calcium to root surfaces. In published trials, growers held the same yield on roughly 20–25% less fertilizer — a matched-yield result, so it is a saving rather than a saving plus extra yield.

Wang et al., 2021 Jannesari et al., 2024

Problem: Salt is concentrating in the exact layer your roots live in

The Problem: Salinity is a water-movement problem before it is a chemistry problem. When pore connectivity is poor, irrigation wets the top of the profile and stops, so every pass leaves its salt behind in the layer where the root system is trying to work. Applying more water without restoring the pore network mostly moves the salt a few inches and brings it back with the next evaporative cycle.

What We Do: Restoring connectivity is what makes leaching actually leach. As aerobic biology reopens the pore network, applied water carries sodium below the root zone instead of stacking it inside it — and a deeper root system is less dependent on that top layer in the first place. Salinity management stays a program with a water budget behind it; oxygen changes how much of each pass does useful work.

Chen et al., 2023 Baram et al., 2022

Problem: Uneven stands cost you time and replanting money

The Problem: Poor germination means patchy stands, wasted seed, and extra labor for replanting. Every gap is lost revenue and an open invitation to weeds. Early establishment is also the moment the crop is most exposed to low soil oxygen, because the seedling has no root system to buffer with yet.

What We Do: Water enriched with ultrafine bubbles improves germination by 15–25% in published research, with markedly more uniform emergence. In one trial, oxygen-enriched water took lettuce from a poor germination rate to near-full emergence in two days. Those are other people's trials on their seed and soils — treat the range as a direction and prove it on a paired strip of your own.

Ahmed et al., 2018 Jannesari et al., 2024

Problem: Your fields release more emissions than they need to

The Problem: Poorly aerated soils run anaerobic microbial pathways that produce nitrous oxide and methane — the same pathways that are eating your nitrogen. It is the identical problem billed twice: once as fertilizer you paid for and lost, and once as an emissions number that increasingly shows up in compliance, reporting and buyer requirements.

What We Do: Oxygenating the root zone shifts microbial activity toward aerobic pathways, which produce far less of both gases. In published field studies, ultrafine bubble aeration cut nitrous oxide and methane emissions materially in drip and paddy trials. The agronomic case and the emissions case are the same intervention — you do not have to choose which one to fund.

Baram et al., 2021 Shi et al., 2018

Problem: Contaminated soil puts your crop quality at risk

The Problem: Heavy metals accumulate in soil over years and pesticide residues linger. Both threaten food safety, export compliance and buyer trust — and neither is visible until a lab tells you about it.

What We Do: Ultrafine bubbles support natural remediation processes. In published research, air ultrafine bubbles raised cadmium uptake in phytoremediation plants, and ozone ultrafine bubbles outperformed conventional washing at breaking down pesticide residues on produce. These are supporting mechanisms with real published backing, not a remediation service — scope them with an agronomist against your own soil tests.
