Sugarcane Fertilizer Calculator
Work out the exact urea, DAP and MOP for sugarcane from the recommended 250:115:115 kg/ha N-P₂O₅-K₂O dose, adjusted to your soil test and field size.
Apply P and K at planting in the furrow. Split N in three to four doses ending by the grand-growth phase (120–150 days); for ratoons apply the first N immediately after stubble shaving. Earth up after the last dose.
Indicative planning figures based on published research averages. Local soil tests, varieties and weather change actual requirements — confirm with your agronomist or extension officer.
Farmers and agronomists use the free Sugarcane Fertilizer Calculator to convert the official sugarcane recommendation into exact urea, DAP and MOP quantities for their own field in seconds — no agronomy tables, no spreadsheet, and it works offline in the field.
About Sugarcane Fertilizer Calculator
A 100-tonne cane crop removes around 200 kg N, so sugarcane carries one of the heaviest fertilizer schedules in Indian agriculture — and ratoons need about 25% more N than plant crops because their root systems are shallower. This calculator starts from the published recommendation of 250:115:115 kg/ha N-P₂O₅-K₂O (plant crop — tropical (12 mo)) or 180:80:80 kg/ha N-P₂O₅-K₂O (plant crop — subtropical) or 280:90:90 kg/ha N-P₂O₅-K₂O (ratoon crop), adjusts it ±25% for your soil-test N, P and K ratings, scales it to your field area in hectares, acres or bigha, and converts the nutrients into real products — urea (46% N), DAP (18-46-0) and MOP (0-0-60) — including the number of bags to buy.
How to use Sugarcane Fertilizer Calculator
- 1Enter your field area and pick the unit (hectare, acre or bigha).
- 2Choose the growing condition (plant crop — tropical (12 mo) / plant crop — subtropical / ratoon crop) and your soil-test ratings for N, P and K — leave Medium if you have no recent soil test.
- 3Read off the urea, DAP and MOP quantities and bag counts, then follow the split-application note for timing.
Why use Sugarcane Fertilizer Calculator?
- ✓Official package-of-practices dose for sugarcane — not a generic NPK guess
- ✓Soil-test Low/Medium/High ratings adjust the dose ±25% automatically
- ✓Converts nutrients to urea, DAP and MOP bags, with the DAP nitrogen credit handled correctly
- ✓Works in hectares, acres and bigha — and runs fully in your browser, even offline in the field
Frequently asked questions
What is the recommended fertilizer dose for sugarcane?+
Plant crop — tropical (12 mo): 250 kg N, 115 kg P₂O₅ and 115 kg K₂O per hectare; Plant crop — subtropical: 180 kg N, 80 kg P₂O₅ and 80 kg K₂O per hectare; Ratoon crop: 280 kg N, 90 kg P₂O₅ and 90 kg K₂O per hectare. Apply P and K at planting in the furrow.
Why does a ratoon crop need more nitrogen?+
Ratoon cane regrows from old stubble with a degraded, shallow root system that is less efficient at mining soil nitrogen, so packages recommend roughly 25% extra N over the plant crop, applied early after ratooning.
When should the last nitrogen dose go on sugarcane?+
Finish all N by the grand growth phase — about 120–150 days after planting. Late N lowers juice sucrose and delays maturity, which directly cuts your sugar recovery payment.
How does the calculator convert NPK into urea, DAP and MOP?+
DAP (46% P₂O₅) is sized to cover the phosphorus need; the nitrogen it also carries (18% N) is credited against the N requirement, and urea (46% N) supplies the balance. MOP (60% K₂O) covers potassium. Bag counts use 45 kg urea and 50 kg DAP/MOP bags.
Is this tool free, and does my data leave the device?+
It is completely free with no sign-up, and all calculation happens in your browser — nothing you enter is uploaded, so it also works offline in the field.
