Five Cuts In: What the Cumulative Data Means for Cost and Nitrogen Strategy
We have now completed five measured pasture cuts from October 2025 through January 2026 across four replicated BioN trial farms in Mid Canterbury.
Rather than focusing on a single growth window, this update looks at cumulative dry matter production across the season to date. When reviewing nitrogen strategy, total feed grown per hectare is what ultimately matters.
All figures presented are based on harvested biomass and laboratory-tested dry matter percentages. There is no modelling or projection, only measured paddock data.
Why Cumulative Data Matters
Nitrogen discussions often centre on short-term response. A strong early lift can look compelling in isolation.
However, nitrogen strategy decisions are made across an entire season. Application frequency, persistence, and total dry matter production per hectare all influence overall farm performance and cost structure.
Cumulative tracking across repeated cuts provides a clearer basis for comparison than isolated measurements.
Cumulative Dry Matter Results (October–January)
After five cuts across four commercial trial farms, the cumulative averages are as follows:
Average dry matter yield (kg DM/ha):
- Urea: 11,376 kg DM/ha
- BioN: 12,649 kg DM/ha
This represents an additional 1,273 kg DM/ha in favour of BioN over the period measured.
Individual farm results varied slightly, as expected under commercial conditions, but the cumulative trend remains consistent across all sites.
Because dry matter percentages remained comparable between treatments, the difference reflects genuine biomass production rather than moisture variation.
Dry matter production is only part of the equation. Cost per hectare and number of nitrogen applications also influence profitability.
When cumulative production is considered alongside:
- Cost of product per hectare
- Number of applications required
- Timing flexibility
- Labour and machinery passes
The discussion shifts from short-term response to overall input efficiency.
An additional 1,273 kg DM/ha across five cuts contributes directly to feed supply. The next step for many farmers is reviewing what that means relative to nitrogen spend across the same period.
That calculation will differ between systems, but cumulative production provides the starting point.
Positioning BioN Within Nitrogen Strategy
BioN is not positioned as a short-term spike product. It operates through biological nitrogen fixation, contributing plant-available nitrogen over time.
Across five cuts this season, that contribution is reflected in cumulative dry matter yield.
For farmers reviewing autumn nitrogen planning, cumulative season-to-date performance provides a practical reference point when assessing:
- Application frequency
- Synthetic nitrogen reliance
- Feed supply stability
- Cost per hectare
Strategic integration is the focus, rather than replacement rhetoric.
What Happens Next
Further cuts will be completed as the season progresses.
Cumulative performance data will continue to be published as it becomes available. The objective remains the same: transparent reporting under commercial farm conditions.
This blog summarises the season-to-date cumulative results.

If you are reviewing nitrogen strategy heading into autumn, we are available to work through the numbers specific to your system.
