Mango Fertilizer Calculator
Per-tree mango fertilizer planner — age-based doses up to 1000:500:1000 g N-P₂O₅-K₂O per tree/year converted into urea, DAP and MOP for your whole orchard.
Apply in two splits — after harvest (with FYM) and after fruit set — in a ring at the canopy drip line. The post-harvest dose decides next year's flowering wood.
Indicative planning figures based on published research averages. Local soil tests, varieties and weather change actual requirements — confirm with your agronomist or extension officer.
Orchardists use the free Mango Fertilizer Calculator to turn the per-tree recommendation into total urea, DAP and MOP for the whole block — young and bearing trees included — without a single hand calculation.
About Mango Fertilizer Calculator
Mango doses climb a ten-year ladder from 100 g to a full kilogram of N per tree — and the most important application is the post-harvest one that grows next season's bearing shoots. The calculator uses the age-laddered recommendation — 100:50:100 g N-P₂O₅-K₂O per tree/year (1–3 years (young)); 400:200:400 g N-P₂O₅-K₂O per tree/year (4–6 years); 700:350:700 g N-P₂O₅-K₂O per tree/year (7–9 years); 1000:500:1000 g N-P₂O₅-K₂O per tree/year (10+ years (full bearing)) — multiplies it across your tree count, and converts the totals into urea (46% N), DAP (18-46-0) and MOP (0-0-60) quantities for the season.

Frequently asked questions
How much fertilizer does a mango tree need per year?+
1–3 years (young): 100 g N, 50 g P₂O₅ and 100 g K₂O per tree per year; 4–6 years: 400 g N, 200 g P₂O₅ and 400 g K₂O per tree per year; 7–9 years: 700 g N, 350 g P₂O₅ and 700 g K₂O per tree per year; 10+ years (full bearing): 1000 g N, 500 g P₂O₅ and 1000 g K₂O per tree per year. Apply in two splits — after harvest (with FYM) and after fruit set — in a ring at the canopy drip line.
When is the best time to fertilize a bearing mango tree?+
Immediately after harvest (June–July in most of India) with FYM — this feeds the new flush that will carry next year's flowers — plus a second lighter dose after fruit set.
How can I reduce alternate bearing through nutrition?+
Consistent post-harvest feeding, adequate K, and not over-fertilizing in 'on' years smooth out the cycle; paclobutrazol programs in commercial orchards work alongside, not instead of, this schedule.
How do I convert the per-tree dose into urea, DAP and MOP?+
The tool multiplies the per-tree grams across your count, then sizes DAP to cover P₂O₅ (crediting its 18% N), urea for the remaining N, and MOP for K₂O — the same arithmetic an agronomist would do by hand.
Is this calculator free and private?+
Yes — free, no sign-up, and everything runs in your browser, so your orchard data never leaves the device and the tool works offline.
