How is fertilizer quantity calculated?

Fertilizer quantity is nutrient required divided by nutrient fraction in fertilizer grade. Example: urea needed = nitrogen required / 0.46.

Can I use acre and hectare both?

Yes. The calculator supports both acres and hectares and converts area internally.

Quickly estimate N, P2O5, K2O requirement and fertilizer quantity for your crop and land area.

Crop Preset Area

Nitrogen N (kg/ha) Phosphorus P2O5 (kg/ha) Potassium K2O (kg/ha)

N Source P Source K Source

Total nutrient need = recommended rate (kg/ha) x area in hectare.

Fertilizer needed (kg) = nutrient need (kg) / nutrient fraction in selected source.

Q: Should all urea be applied once?
A: Usually split in 2-3 doses based on crop stage to reduce losses.

Q: Can soil test recommendations override this?
A: Yes, always prioritize soil test based advisory if available.
