New corn trial data: Arginex Corn proven to deliver up to 4.3% more grain yield with 30% less nitrogen fertiliser in independent trials across Europe and South America
+4.3% more corn grain yield with 30% less nitrogen fertiliser
- Independent trials across the two continents show Arevo’s non-microbial seed treatment holds crop performance while cutting standard fertiliser input, even as conditions get tougher.
- Key results include:
- more yield with less input: up to +4.3% grain yield at 30% reduced standard nitrogen,
- same yield, less fertiliser: standard-practice yields matched at 30% less nitrogen – and with 40% less nitrogen and phosphorus in South American trials (p<0.001),
- more yield on standard practice: +3.4% average uplift when applied on top of full fertiliser rates.
- Arevo will present full trial results at the Euroseeds Congress 2026 in Valencia, 25–28 October.
UMEÅ, Sweden ‒ 21st September, 2026 ‒ Agtech company Arevo today released new results from independent field trials of Arginex Corn, its arginine-based crop nutrition applied as a seed treatment. Across trial sites in France, Germany, Italy, Spain, Poland and Brazil, corn treated with Arginex delivered up to 4.3% higher grain yield while standard nitrogen fertiliser was reduced by up to 30% – proving growers can produce more with less input.
The trials run across different soil pH levels and textures and showed consistent, repeatable results:
- Up to +4.3% more grain yield at 30% reduced standard nitrogen – a statistically significant uplift over full-rate standard practice in a 2025 European trial.
- Yield on par with full-rate standard practice at 30% less nitrogen with the seed treatment alone.
- +3.4% average grain yield uplift when applied on top of full standard fertiliser – up to +3.8% at a single site – showing the treatment adds value even without cutting inputs.
- Full fertiliser programme matched with 40% less nitrogen and phosphorus across three South American trial sites – highly significant (p<0.001) at every site.
- Up to +4.7% whole-plant silage biomass at 25% reduced nitrogen, extending the case to silage corn
- No penalty on germination, and up to +8.0% increase in plant height.
The results come from replicated, multi-treatment factorial field trials run by independent contract research organisations across Europe and South America between 2024 and 2025, with treatment effects confirmed by statistical analysis.
And they come at a time when seed producers, breeders, and retailers are looking for ways to make their products more climate-resistant with Western Europe seeing its hottest June–July period on record and England and Wales its driest July, resulting in low soil moisture and another disastrous wildfire season. Recent years have also seen increasingly severe heatwaves, droughts, wildfires, and excessive rains and flooding over South America.
“Farming is unpredictable. Arginex is not,” said Niklas Åström, CEO of Arevo. “Because Arginex is a non-living, single-compound formula, every batch contains the exact same molecule. The data show it consistently improves yield and nitrogen use efficiency – more crop per unit of nitrogen, season after season. That’s what growers need when everything else in the field keeps changing.”
Arginex Corn combines arginine with phosphate in a stable, slow-release complex that plants take up intact, without prior mineralization. Unlike biostimulants built on living microbes or variable blends, it is a non-microbial formulation with a long shelf life, stable on-seed and compatible with standard seed treatment programs. The arginine also supports soil biology, attracting mycorrhizal fungi and strengthening root systems for stronger early growth.
Arevo welcomes commercial partners in corn and upcoming wheat seed coating products and will present the full trial data at the Euroseeds Congress 2026 in Valencia, Spain, 25–28 October, under the theme “Farming is unpredictable. Arginex is not.”
About Arevo
Arevo is an Agtech company redefining crop nutrition from the ground up. Rooted in science and built commercially for agriculture, forestry and horticulture, its mission is to reduce dependence on synthetic fertilisers and support more sustainable cultivation practices with zero nitrogen waste. Based on decades of research, Arevo’s patented organic nitrogen technology, Arginex – where arginine meets phosphorus – enhances a plant’s natural ability to absorb nutrients and water while supporting beneficial soil microbes, resulting in stronger, more resilient plants that better withstand environmental stresses. Backed by extensive field trials, CE-marking and 70+ patents.
