Carrot Fertilizer Calculator
Work out the exact urea, DAP and MOP for carrot from the recommended 80:40:60 kg/ha N-P₂O₅-K₂O dose, adjusted to your soil test and field size.
Half N + full P, K basal on deeply-worked beds; rest N at 30 days. Never apply fresh manure to the carrot bed itself — it forks the roots. K builds colour and core sweetness.
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 Carrot Fertilizer Calculator to convert the official carrot 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 Carrot Fertilizer Calculator
Carrot quality is shaped below ground: K-led feeding on deep loose beds gives straight, sweet, well-coloured roots, while fresh manure or clods cause the forking that ruins market grade. This calculator starts from the published recommendation of 80:40:60 kg/ha N-P₂O₅-K₂O (rabi (plains)), 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 Carrot Fertilizer Calculator
- 1Enter your field area and pick the unit (hectare, acre or bigha).
- 2Choose the growing condition 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 Carrot Fertilizer Calculator?
- ✓Official package-of-practices dose for carrot — 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 carrot?+
Rabi (plains): 80 kg N, 40 kg P₂O₅ and 60 kg K₂O per hectare. Half N + full P, K basal on deeply-worked beds; rest N at 30 days.
Why do my carrots fork and branch?+
Fresh/uncomposted manure, stones or compaction in the root zone make the taproot split. Use only well-rotted FYM applied to the previous crop, and deep-till the bed.
Which nutrient improves carrot colour?+
Potassium (with adequate boron) deepens carotene colour and sweetness; the 60 kg K2O in this plan is doing the quality work, not just the yield.
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.
