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.
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.
Preparing a commercial purchase? Commercial fertilizer procurement brings specification and offer comparison together. Human-led RFQs start at USD 250,000; calculator estimates do not qualify a purchase budget.
Project inputs
Typical for Tomato (greenhouse): 300 t/ha
Split the programme: 3–6 for field crops, 10–40 fertigation events for a protected crop. Sets the application rate per hectare per event and the delivery schedule in the RFQ.
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.
Scoping estimate only. Local prices, freight, blending and fertigation-grade premiums change the final invoice.
Annual fertilizer supply RFQTurn this estimate into a project brief
Send these figures to the fertilizer supply RFQ. Your inputs and results are attached to the private brief, a sourcing specialist reviews it, and only then is supplier outreach considered.
Buying more than once? Save these project details to your buyer profile so your site, crop, budget and timeline are pre-filled on every future request.
Indicative only. Not financial advice, not agronomic advice, not engineering design. Final numbers require supplier, agronomist, engineer and local regulatory review.

Frequently asked questions
By multiplying target yield (tonnes) by indicative nutrient removal per tonne (N, P₂O₅, K₂O). The tool then converts nutrient demand into product rate for urea (46-0-0), DAP (18-46-0) and MOP (0-0-60) at commonly used bulk prices. Actual programs must be tuned to soil test, water quality, crop stage and residual fertility.
No. It covers macro-nutrient N-P-K only, which drives 80–90% of fertilizer spend. Micronutrients (Ca, Mg, S, Fe, Zn, B, Mn, Mo) and foliar/biostimulant programs are scoped in the project agronomy plan and specified in the RFQ.
They are conservative agronomic averages used for project scoping and RFQ preparation. Field or greenhouse trials, local extension recommendations and soil analysis should refine the numbers before the growing season starts.
No. SeedMatchGroup is supplier-neutral. We help buyers specify fertilizer volumes, delivery windows and packaging, then open one private RFQ to qualified fertilizer traders, blenders and fertigation-grade suppliers.

Understanding the values
What each choice in this calculator means, and how the options differ in practice.
- Crop nutrient requirement
- The total nutrient the crop removes at your target yield. Higher yield targets remove more nutrients and need higher application.
- Soil supply
- What the soil already provides, from a soil test. Skipping the test means guessing — usually over-applying nitrogen and under-applying potassium.
- Fertiliser grade
- The analysis on the bag (for example 15-15-15) sets how much product delivers a kilogram of nutrient. Different grades change the product quantity, not the nutrient need.

Illustration only, not a real project or quotation. This is the structure, equipment and site-works budget for the example greenhouse, not the price of this calculator’s individual system, seeds or inputs, and not a result calculated from your entries.

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

Method and decision path
How to use this result in a commercial project
Use the result to test scope and compare scenarios. It is not a design, agronomic prescription, financing offer or supplier quotation.
1. Enter site evidence
Replace defaults with measured area, climate, water, energy, crop and commercial assumptions.
2. Test scenarios
Change one assumption at a time and record the effect on capacity, cost, demand or return.
3. Validate the duty
Ask the relevant agronomist, engineer or financial adviser to check the inputs and constraints.
4. Prepare a private RFQ
Carry the confirmed scope into a human-reviewed brief so written offers can be compared on the same basis.
Final specifications, performance, prices, supplier participation and timing depend on the site and written supplier responses; none is guaranteed by this calculator.
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.
The USD 250K project threshold applies to capital projects. Recurring fertilizer programmes are reviewed by shipment size, annual volume and sourcing fit.
A sourcing specialist shortlists reviewed providers for your scope and returns comparable offers. Supplier details stay with us — all communication runs through SeedMatchGroup.
