Turmeric Fertilizer Calculator
Work out the exact urea, DAP and MOP for turmeric from the recommended 125:38:75 kg/ha N-P₂O₅-K₂O dose, adjusted to your soil test and field size.
Full P basal with 25 t/ha FYM at planting; N and K in three equal splits at 45, 90 and 120 days, each followed by earthing-up. Rhizome bulking after 90 days is when K earns its keep.
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 Turmeric Fertilizer Calculator to convert the official turmeric 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 Turmeric Fertilizer Calculator
Turmeric spends nine months underground building rhizomes, so its K-rich schedule is spread across three earthing-ups — and the 25-tonne FYM base is as much a part of the package as the NPK. This calculator starts from the published recommendation of 125:38:75 kg/ha N-P₂O₅-K₂O (irrigated (with 25 t fym)), 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 Turmeric 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 Turmeric Fertilizer Calculator?
- ✓Official package-of-practices dose for turmeric — 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 turmeric?+
Irrigated (with 25 t FYM): 125 kg N, 38 kg P₂O₅ and 75 kg K₂O per hectare. Full P basal with 25 t/ha FYM at planting; N and K in three equal splits at 45, 90 and 120 days, each followed by earthing-up.
Why is potash so important for turmeric?+
K drives rhizome bulking and curcumin accumulation in the final third of the crop; that's why a third of the K arrives as late as 120 days, with the last earthing-up.
Can turmeric be grown without heavy FYM?+
Yields drop sharply. The standard package pairs ~25 t/ha FYM with 125:38:75 NPK; the organic matter keeps the ridge soil loose enough for rhizomes to expand.
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.
