Field pea Fertilizer Calculator
Work out the exact urea, DAP and MOP for field pea from the recommended 25:50:25 kg/ha N-P₂O₅-K₂O dose, adjusted to your soil test and field size.
Full dose drilled basal below the seed with rhizobium-treated seed. Like other rabi pulses it is rarely top-dressed; a 2% urea foliar at podding is the rescue option on pale stands.
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 Field pea Fertilizer Calculator to convert the official field pea 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 Field pea Fertilizer Calculator
Grain peas run the standard rabi-pulse program — P-led basal, rhizobium, no top-dress — and reward early sowing more than any extra fertilizer. This calculator starts from the published recommendation of 25:50:25 kg/ha N-P₂O₅-K₂O (rabi (grain)), 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 Field pea 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 Field pea Fertilizer Calculator?
- ✓Official package-of-practices dose for field pea — 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 field pea?+
Rabi (grain): 25 kg N, 50 kg P₂O₅ and 25 kg K₂O per hectare. Full dose drilled basal below the seed with rhizobium-treated seed.
What is the difference between feeding field pea and garden pea?+
Grain/field pea gets the lean 25:50:25 pulse plan; vegetable garden pea picked green over weeks runs a bigger 50:60:50 plan with a nitrogen split, because pods are harvested repeatedly at peak demand.
Should field pea seed be inoculated every season?+
Yes — Rhizobium leguminosarum inoculation is cheap insurance for nodulation, particularly in fields new to peas or following long cereal runs.
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.
