🌾 Crop Emissions Estimator

Estimate field emissions per hectare and per kg product from a few inputs. Runs fully in your browser with PDF export.

Inputs

Crop

Select rice for extra methane term.

Yield (t/ha)

Harvested product per hectare.

Nitrogen fertilizer (kg N/ha)

Total mineral + manure N applied (as N).

Diesel use (L/ha)

Tillage, planting, spraying, harvest, etc.

Agricultural lime applied (t/ha)

If none, leave 0. Lime emits CO₂ when it dissolves.

N₂O EF (fraction of N → N₂O-N)

Default 1% (IPCC Tier 1). Range ~0.3–2% typical.

Total emissions (per hectare)

Intensity (per kg product)

t CO₂e/ha ÷ yield (t/ha) → g CO₂e/kg

Category	Formula (v1)	t CO₂e/ha
Total

Breakdown by category (pie)

Category totals (t CO₂e/ha)
