Wheat Fertilizer Calculator
Work out the exact urea, DAP and MOP for wheat from the ICAR 120:60:40 kg/ha dose, adjusted for sowing time and your soil test.
Apply full DAP and MOP at sowing; split urea โ half basal, half at first irrigation (crown root initiation, ~21 days). For late-sown wheat give the second urea dose earlier.
Indicative planning figures based on published research averages. Local soil tests, varieties and weather change actual requirements โ confirm with your agronomist or extension officer.
Farmers and agronomists rely on the free Wheat Fertilizer Calculator for accurate, instant results in the field โ no spreadsheet, no sign-up, and it works offline.
About Wheat Fertilizer Calculator
Irrigated, timely-sown wheat is fertilized at the ICAR recommendation of 120:60:40 kg/ha N-PโOโ -KโO, with late-sown and rainfed crops scaled down. This calculator adjusts that ยฑ25% for your soil-test ratings, scales it to your field, and converts it into urea, DAP and MOP โ including the basal/top-dress split at crown-root initiation.

Frequently asked questions
What is the fertilizer dose for wheat per acre?+
Irrigated timely-sown wheat needs 120:60:40 kg/ha N-PโOโ -KโO (about 48:24:16 kg/acre). Late-sown wheat drops to roughly 90:45:30 and rainfed to 60:30:20. The tool converts this to urea, DAP and MOP for your area.
When should I top-dress nitrogen on wheat?+
Apply half the nitrogen and all the phosphorus and potash at sowing, then the second half of the nitrogen at the first irrigation (crown-root initiation, ~21 days). Late-sown wheat needs the second dose a little earlier.
Is this tool free and private?+
Yes โ completely free with no sign-up, and every calculation runs in your browser, so it works offline and your data never leaves the device.
