Kilograms of grain produced for every kilogram of applied nitrogen — a direct read on how hard your single most expensive and most emissions-heavy input is working across the program.
Partial nitrogen productivity in dryland cereals commonly runs 25–50 kg of grain per kilogram of applied N; the efficient top tier sits at the upper end for the same season.
GRDC GrowNotes ↗Low efficiency means nitrogen is being lost to leaching, volatilisation or denitrification rather than ending up in grain — a cost to both the budget and the emissions figure. Rising efficiency usually tracks better timing and placement, not simply cutting rates.
Silo pulls each of these from the sources the operation already uses, and keeps the figure current automatically.
Split nitrogen and apply in-crop to match supply to seasonal demand.
Use soil and tissue testing to credit mineralised N and avoid over-application.
Place and incorporate N to cut volatilisation losses from the surface.

You need: Grain yield (kg/ha), Nitrogen applied (kg N/ha), Soil mineral N at sowing (kg N/ha). Silo pulls each of these from the sources the operation already uses and keeps the figure current automatically.
