The cheapest nitrogen application you'll ever make. 2 years in a row.
Two consecutive PTI on-farm trials. Two different hybrids. The same result both times — more grain, positive net return, at an application cost of $0.03/L.
The numbers. Straight from the trial.
Precision Technology Institute is a US-based manufacturer-run (AGCO) agricultural research organisation conducting replicated on-farm trials. Their 2024 and 2025 on-farm trials tested Green Lightning as a single 75 L/ha foliar application at V6 — sprayed directly onto the plant, not the soil. Two consecutive years. Two different hybrids. Here's what they found.
$2.25 in. $51–$66/ha back. Two years running.
The application cost for a 75 L/ha foliar pass is $2.25/ha at Australian operating rates. The net return gain across both PTI trial seasons averaged $58/ha AUD.
That's a return of more than 25 times the input cost — from a single foliar application at V6.
Nature figured this out long before we did.
During a lightning storm, static electricity restructures nitrogen molecules in the air. That modified, highly reactive nitrogen is carried down in rain. Plants have evolved over millions of years to use it directly — a readily plant-available form of nitrogen.
Green Lightning replicates that process on demand, on your farm.
Air and water pass through a gliding plasma arc inside the machine. Nitrogen from the air is restructured and dissolved into the water as NO₃ (nitrate) — the dominant and most plant-available form — with trace NO₂ (nitrite). The result is plasma activated water: a liquid nitrogen source that plants take up fast, efficiently, and with minimal loss to the environment.
You're not buying nitrogen. You're making it. From air and water. At $0.03/L.
This discussion assesses whether Green Lightning fits your current nitrogen program, cropping system, and logistics.
