Untreated plots yielded substantially lower. # What was tested - Commercial irrigated winter wheat system - 2025 growing season - Individual irrigation bays treated as experimental units - Plasma Strike applications timed exactly with commercial urea passes **Baseline:** - Starter nitrogen applied at planting - Two irrigation events during the season - Irrigation water contained background nitrogen This trial evaluates **in-season nitrogen performance**, not zero-input systems. ## Measurements - Leaf tissue testing - Nitrate-N (indicator of plant nitrogen status) - Ammonia-N (indicator of nitrogen uptake and assimilation pathways) - Sampling conducted twice weekly throughout the season - Biomass observations - Final grain yield mapping at harvest *Dataset includes 70 tissue samples collected across replicated bays during the 2025 season.* ## Yield - All fertilised treatments produced significantly higher grain yield than the untreated baseline - **No meaningful yield difference** was observed between: - Commercial urea treatments, and - Plasma Strike treatments at comparable application timings - Yield equivalence was observed across replicated irrigation bays. ![Screenshot 2026-02-06 160629-1](https://441678811.fs1.hubspotusercontent-ap1.net/hub/441678811/hubfs/Screenshot%202026-02-06%20160629-1.jpg?width=1200&length=1200&name=Screenshot%202026-02-06%20160629-1.jpg) Example leaf tissue analysis (nitrate-N, ammonia-N). Multiple samples collected across season. ![yeild map](https://441678811.fs1.hubspotusercontent-ap1.net/hub/441678811/hubfs/yeild%20map.jpg?width=1200&length=1200&name=yeild%20map.jpg) Representative yield map from replicated irrigation bay (t/ha). **Interpretation:** Under these conditions, Plasma Strike delivered **equivalent yield outcomes** to commercial urea programs. ## Nitrogen-N response (leaf tissue) - Plasma Strike treatments showed a **more rapid increase in leaf nitrate-N** following application - Urea treatments showed **higher nitrate-N levels later in the cycle (approximately 3–4 weeks post-application)** - Distinct nitrate-N spikes aligned with irrigation events, consistent with background nitrogen in irrigation water **Interpretation:** Plasma Strike resulted in a **faster plant nitrate response**, while urea followed a delayed availability pattern consistent with urea conversion dynamics. ## Ammonia-N response (leaf tissue) - No meaningful differences in leaf ammonia-N were observed between treatments **Interpretation:** Nitrogen uptake dynamics were comparable across fertilised treatments. ## Biomass - Biomass and tiller density were comparable across all fertilised treatments - Untreated plots showed reduced tillering and overall leaf mass **Interpretation:** Observed yield differences align with nitrogen treatment effects rather than biomass anomalies. ![Nitrate-N chart](https://go.plasmastrike.com.au/hubfs/Nitrate-N%20chart.jpg "Nitrate-N chart") ## What these results support - Plasma Strike achieved **equivalent yield outcomes** to commercial urea in this irrigated winter wheat system - Plasma Strike produced a **faster in-season nitrate response** following application ## Scope of these results These results demonstrate **equivalent yield performance** between Plasma Strike and commercial urea **within the system tested**. They do **not** attempt to demonstrate: - Full nitrogen replacement - Performance independent of background soil or irrigation nitrogen - Applicability across all crops, seasons, or management systems This trial is intentionally scoped to **in-season nitrogen performance** in an irrigated winter wheat system. ## Who this is for - Irrigated cereal growers - Operations already making multiple in-season spray passes - Growers evaluating **partial substitution** of synthetic nitrogen - Decision-makers who require field data before change [Download the Report (.pdf)](https://go.plasmastrike.com.au/hubfs/Report%20Green%20Lightening%20Fert%20Trial%20Winter%20Wheat%202025.pdf?hsLang=en-au) [See all our Data](https://go.plasmastrike.com.au/plasma-strike-trial-data?hsLang=en-au) [Discuss fit for your nitrogen program](https://7aypjv.share-ap1.hsforms.com/2yOnGFmW5QT-2WCqfRYj6uA) This discussion assesses whether Plasma Strike fits your current nitrogen program, cropping system, and logistics.
