Your yard already has all the fertilizer it needs. It's in the air above it.
The air around your home is 78% nitrogen — the same nutrient you've been buying in bags for years. AirFeed captures it, converts it to liquid plant food, and delivers it straight to your garden. No store runs. No bags. No spreading. Ever again.
Technology in development. Specifications below reflect intended design pathway and target performance. Patent pending — U.S. Provisional Application No. 64/052,149 (filed April 28, 2026). Provisional applications do not constitute issued patent protection.
The big idea
One number explains everything.
78%
of air is nitrogen
Plants need nitrogen to grow. Air is almost entirely nitrogen. The problem was always getting it from up there to down here — in a form plants can actually use. AirFeed solves that, for the first time, at the scale of your backyard.

Step by step
What happens inside AirFeed.
AirFeed has no moving parts, no electricity requirement, and no ongoing chemistry you need to manage. Here's what the device is actually doing, in plain language.
1
Humid air enters through the top
The device has air intake slots along the top of its housing. On humid days — mornings, evenings, after rain — moisture-laden air drifts naturally through the device. No fan required. The more humidity in the air, the more the device has to work with.
Why humidity matters: The reaction that converts nitrogen into plant food requires both N₂ molecules (from the air) and water vapor (also from the air) as a proton source. Think of moisture as the fuel that drives the chemistry. Even in relatively dry climates, there's enough atmospheric humidity to run the reaction — output scales with local humidity levels.
2
The first mesh layer conditions the air
Before the air reaches the main catalyst, it passes through a surface conditioning mesh coated with humic acid and potassium silicate. This layer does two things: it makes the surface more attractive to water vapor (helping moisture condense out of the air), and it begins delivering potassium and silicon into the liquid that forms on the mesh surface.
What this layer contributes: Potassium (K) — a macronutrient your plants need for strong roots and disease resistance. Silicon (Si) — a micronutrient that strengthens cell walls and improves stress tolerance. Humic acid — a natural chelating compound that improves how plants absorb nutrients.
3
The catalyst mesh fixes nitrogen at room temperature
This is the core of what makes AirFeed different from anything else in your garden center. The second mesh layer is coated with an iron-based catalyst that breaks apart the nitrogen molecule (N₂) — normally one of the most stable and difficult molecules to crack — at room temperature and ambient pressure.
In industrial fertilizer manufacturing, that same nitrogen-cracking step requires reactors running at 500°C and 200 times atmospheric pressure, burning natural gas. AirFeed's intended design pathway achieves the same result at the ambient conditions outside your back door.
Intended chemistry pathway: Iron oxide active sites on the mesh surface adsorb N₂ molecules. Water vapor provides hydrogen atoms via the Nafion ionomer coating. The stepwise reduction produces ammonia (NH₃), which dissolves into the moisture collecting on the mesh. The K₂O component of the catalyst coating is intended to promote active site density — the same promoter chemistry used in industrial Haber-Bosch catalysts, now applied at ambient conditions. This is the intended design pathway — consumer-scale validation is in development.
4
Liquid fertilizer drips into the reservoir
As ammonia forms in water droplets on the mesh surface, it runs down into the 2-gallon sealed reservoir below. The reservoir is where the liquid becomes a complete plant food — because sitting at the bottom is an AirFeed Pellet.
What the Pellet adds: The 30-day dissolving Pellet contains monopotassium phosphate (MKP) for phosphorus, magnesium sulfate for magnesium, and a trace mineral blend including iron, zinc, manganese, and boron. Together with the nitrogen from the mesh, the reservoir produces liquid fertilizer that addresses all major plant nutrient categories — from a single sealed unit that requires no mixing, measuring, or chemistry knowledge to operate.
5
You draw from the reservoir when you're ready to feed
A standard ¾" garden hose adapter at the base of the device lets you connect directly to your existing hose or drip irrigation system. Draw what you need, when you need it. There's no mixing, no measuring, no sprayer to clean up afterward — just a reservoir of ready-to-use liquid plant food sitting outside your back door.
The practical difference: Most fertilizer application problems come from over-application — spreading a full bag because that's how the product is sized, not because that's how much the lawn needs. A reservoir you draw from changes the default behavior to "use what you need." That's better for your plants and better for the watershed downstream.
What's inside
The three components that do the work.
AirFeed has no circuit board, no motor, no timer. It's a system of two specialized mesh layers and a reservoir — each with a distinct, complementary function.
Layer 1 — Air side
Surface Conditioning Mesh
Attracts atmospheric moisture, begins nutrient delivery. Stainless steel mesh substrate coated with humic acid and potassium silicate.
Delivers: K (potassium) · Si (silicon) · Humic acid
Layer 2 — Catalyst
Nitrogen Fixation Mesh
The core of the device. Intended to convert N₂ from the air into ammonia (NH₃) at room temperature. Iron oxide catalyst with Nafion proton-exchange coating.
Intended: N₂ + H₂O → NH₃ (at ambient conditions)
Reservoir + Pellet
Complete Nutrient Delivery
Collects the liquid from the meshes. The 30-day dissolving Pellet adds phosphorus, magnesium, and trace minerals to round out the nutrient profile.
Adds: P · Mg · Fe · Zn · Mn · B
What your plants get

Common questions
Let's clear a few things up.
❌ Common assumption
"This sounds like a magic box — nitrogen doesn't just come from air."
✓ What's actually happening
Nitrogen does come from air — always has. Air is 78% N₂. The challenge has always been fixing it: breaking the N₂ triple bond and converting it to a plant-usable form. Industrial fertilizer does this in massive high-pressure reactors. AirFeed's intended design pathway achieves it on a catalyst mesh at the conditions outside your back door.
❌ Common assumption
"It must use a lot of electricity to do this."
✓ What's actually happening
The base AirFeed model uses zero electricity. The catalyst mesh operates passively — driven by humidity and natural airflow. The BoltBrew model adds 50W solar power to enhance nitrogen fixation rate for drier climates, but the passive AirFeed requires no power connection whatsoever.
❌ Common assumption
"If it worked, someone would already be selling it."
✓ What's actually happening
Academic groups at Stanford, Eindhoven University, and MIT have all published research demonstrating ambient-condition nitrogen fixation on catalyst surfaces. What hasn't existed — until now — is a consumer-deployable product built around this chemistry. That gap is exactly what C&C's Fertilizer is designed to close.
❌ Common assumption
"What if it doesn't rain? Does it stop working?"
✓ What's actually happening
AirFeed works on atmospheric humidity, not rainfall. Even in relatively dry climates, there's enough moisture in the air to run the reaction — output scales with local humidity rather than stopping when there's no rain. The BoltBrew model with active plasma discharge is designed for lower-humidity environments like the Southwest.
FAQ
More questions, answered.
Is AirFeed safe for pets and children?▾
The device is sealed during operation — there are no open chemicals, no loose granules, and no spraying involved in the fixation process. The liquid fertilizer it produces is a dilute aqueous solution that you draw from the reservoir and apply where and when you choose. Treat AirFeed output the same way you would any liquid plant food — keep it out of reach of children and avoid ingestion. We are preparing a full pet and family safety statement and will publish it here as soon as it is complete.
How long does the AirFeed Pellet last?▾
The AirFeed Pellet is designed as a 30-day dissolution consumable. It sits in the sealed reservoir and slowly dissolves over approximately one month, contributing phosphorus, magnesium, iron, zinc, manganese, and boron to the liquid as it does. At the end of 30 days, you drop in a new Pellet — no tools, no cleaning, no mess. Pellets are available directly from airfertilizer.com.
How often does the mesh need to be replaced?▾
The catalyst mesh is designed as an annual consumable — the target replacement cycle is approximately 6–12 months depending on climate and usage. Replacement mesh cartridges are available from airfertilizer.com. You don't replace the housing, the reservoir, or any other part of the device — only the mesh layer itself.
Will AirFeed work in a dry climate like Arizona?▾
The passive AirFeed model works best in climates with regular humidity above 40%. For arid or desert climates — including most of the American Southwest — we're developing BoltBrew, which uses 50W of solar power to run a plasma arc that achieves nitrogen fixation without depending on atmospheric moisture. A fan-assisted AirFeed variant for low-airflow conditions is also in the product roadmap. If you're in a dry climate, join the notification list and indicate your region — we'll notify you when the right product for your climate is available.
Is AirFeed organic?▾
AirFeed's nitrogen source is literally the atmosphere — no animal inputs, no biosolids, no mined synthetic inputs. Whether that qualifies for formal organic certification depends on the certifying body and specific criteria. We are pursuing OMRI listing and will update this page when certification status is confirmed. In the meantime, we won't claim organic certification we haven't yet earned.
