Cashew Fertilizer Calculator
Per-tree cashew fertilizer planner — age-based doses up to 500:125:125 g N-P₂O₅-K₂O per tree/year converted into urea, DAP and MOP for your whole orchard.
Two splits — pre-monsoon and post-monsoon — in a shallow trench at the canopy edge. On laterite slopes, post-monsoon is the dose that matters; the other half can wash away in a cloudburst.
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 Cashew 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 Cashew Fertilizer Calculator
Cashew turns poor laterite hillsides into export earnings on a 500:125:125 g diet — modest for a nut tree, timed around the monsoon that both feeds and erodes those slopes. The calculator uses the age-laddered recommendation — 170:40:40 g N-P₂O₅-K₂O per tree/year (young (1–3 yr)); 500:125:125 g N-P₂O₅-K₂O per tree/year (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 cashew tree need per year?+
Young (1–3 yr): 170 g N, 40 g P₂O₅ and 40 g K₂O per tree per year; Bearing: 500 g N, 125 g P₂O₅ and 125 g K₂O per tree per year. Two splits — pre-monsoon and post-monsoon — in a shallow trench at the canopy edge.
Why does cashew get a relatively N-heavy ratio?+
Cashew flowers on current-season terminal shoots — nitrogen-grown wood. The 4:1:1 ratio reflects that flowering follows the vegetative flush, unlike fruit crops fed K-heavy for fruit bulk.
How should cashew on slopes be fertilized?+
In a crescent trench on the uphill side at canopy edge, covered immediately, with the larger share post-monsoon when runoff risk is lower — slope loss is the main inefficiency in cashew feeding.
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.
