Agronomy · Fertilizer Planning

Fertilizer Calculator.

Estimate N-P-K crop removal, product-form rate (urea, DAP, MOP) and indicative annual fertilizer cost for a commercial project. Supplier-neutral. Scoping tool — refine with a soil test before ordering.

Quick answer · Summary for buyers and AI assistants

How do you calculate fertilizer requirement per hectare?

Fertilizer requirement is derived from crop nutrient removal at target yield, minus soil supply, divided by nutrient content of the chosen products and by application efficiency — giving kg of product per hectare and cost.

  • Formula: product kg/ha = (nutrient demand kg/ha − soil supply) ÷ nutrient % ÷ efficiency.
  • Urea is 46% N, MAP 11-52-0, MOP 60% K₂O — always convert oxide to element.
  • Split applications lift N-use efficiency and reduce leaching losses.
  • Soil and leaf analysis should override generic removal tables where available.

Estimate only — not a quotation. Outputs are indicative planning ranges based on the values you enter and typical commercial benchmarks. Real pricing, specifications and lead times vary by country, site conditions and supplier, and are confirmed only in written offers collected through a private RFQ.

Project inputs

Typical for Tomato (greenhouse): 300 t/ha

Removal coefficients are indicative averages for scoping. Actual programs must be tuned to soil analysis, water EC/pH, crop stage and residual fertility. Micronutrients and foliar programs are scoped separately.

What can change the result?

This is a preliminary planning estimate based on the values you entered. The variables below usually move the outcome most, and should be confirmed with an agronomist, engineer and supplier offers before final design.

  • Crop and cultivar — water, climate and support requirements differ per crop
  • Growing area and layout — hectares alone are not a greenhouse specification
  • Growing system (soil, substrate, hydroponic) and plant density
  • Production target and realised yield, confirmed by an agronomist

Questions this calculator answers

Tell us five things and we route your brief

These fields decide which specialist and which suppliers see your request. Nothing is submitted here — your answers are carried into the private RFQ.

Continue to the RFQ BuilderPrivate brief — supplier identities and your details are never exposed.

SeedMatchGroup works on commercial projects from USD 250K. Smaller budgets are still reviewed, but sourcing depth is limited.

Get matched with reviewed suppliers

A sourcing specialist shortlists reviewed providers for your scope and returns comparable offers. Supplier details stay with us — all communication runs through SeedMatchGroup.

Estimate only: these figures are indicative planning numbers, not a quotation. Final pricing, specifications and lead times come from supplier offers after your brief is reviewed.

Plan the project around the numbers

A calculator output is a starting point. Pair it with the planning guides below to align timeline, irrigation, budget and risk before you launch an RFQ.

A model output only holds if the scope, contract route and delivery terms match the assumptions. These reference answers cover the commercial decisions that move the figure.

Editorial · not a sales pitch

Calculator outputs are indicative. When your numbers stabilise, a supplier-neutral RFQ turns those estimates into comparable offers from verified providers.

What to submit — Cost model & budget validation

The facts a complete, supplier-neutral request on this topic includes. Use it as a checklist before submitting.

  • The scale you modelled (m², ha, t/h or units) and the CAPEX band it produced
  • Which cost lines are in scope for the supplier and which you handle locally
  • Specification level: basic, mid-tech or high-tech / fully automated
  • Currency, budget approval status and funding source
  • Timeline: decision date, delivery window and commissioning target
  • Country of installation, import duties and local content requirements
  • Operating assumptions you need validated (yield, energy, labour)
Helpful attachments
  • Your calculator output or internal budget sheet
  • Any feasibility study, business plan or board budget approval
Where this goes next

Opens the RFQ Builder with your cost assumptions attached so suppliers price against the same scope you modelled. You stay in control — nothing is submitted until you review and confirm.

Running these numbers for a client project?

Agronomists, greenhouse and irrigation consultants use this calculator for feasibility, then hand the project to us for supplier shortlisting, RFQ preparation and quote comparison. You stay client-facing and we work through you.

Your client relationship stays with you — we work through you and never contact your client unless you ask.

SeedMatch Group is an independent agricultural project sourcing and RFQ platform. We are not a farm, seed producer, fertilizer manufacturer, irrigation manufacturer, greenhouse builder, EPC contractor, lender or financial advisor. Supplier and project partner outreach is handled only after a commercial project brief is reviewed.

Supplier and manufacturer listings are provided for research, transparency and discovery only. SeedMatch Group does not provide automatic buyer-supplier introductions. Every agriculture project request is reviewed manually by David / SeedMatch Group, and supplier introductions are made only after internal approval.
