Cabbage Fertilizer Calculator
Work out the exact urea, DAP and MOP for cabbage from the recommended 150:80:80 kg/ha N-P₂O₅-K₂O dose, adjusted to your soil test and field size.
Half N + full P, K at transplanting; remaining N in two splits at 25–30 days and at head initiation. All N must be in before heads firm — late N splits heads.
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 Cabbage Fertilizer Calculator to convert the official cabbage 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 Cabbage Fertilizer Calculator
Cabbage builds a head almost entirely from nitrogen-driven leaf growth, but the timing matters more than the total: N after head formation causes loose heads and bursting. This calculator starts from the published recommendation of 150:80:80 kg/ha N-P₂O₅-K₂O (main season) or 120:80:60 kg/ha N-P₂O₅-K₂O (early 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 Cabbage Fertilizer Calculator
- 1Enter your field area and pick the unit (hectare, acre or bigha).
- 2Choose the growing condition (main season / early 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 Cabbage Fertilizer Calculator?
- ✓Official package-of-practices dose for cabbage — 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 cabbage?+
Main season: 150 kg N, 80 kg P₂O₅ and 80 kg K₂O per hectare; Early crop: 120 kg N, 80 kg P₂O₅ and 60 kg K₂O per hectare. Half N + full P, K at transplanting; remaining N in two splits at 25–30 days and at head initiation.
Why do my cabbage heads crack or burst?+
Head bursting follows late nitrogen or sudden heavy irrigation after the head has firmed. Finish all N by head initiation and keep moisture even through maturity.
What is a good fertilizer plan for early cabbage?+
Early-season cabbage has a shorter frame to build yield, so the plan trims N and K to about 120:80:60 kg/ha and front-loads it — half N basal and the rest by 30 days.
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.
