Calculadora de densidad de siembra
Calcule la dosis de siembra de cualquier cultivo comercial a partir de la población objetivo, el peso de mil semillas, la germinación, la emergencia en campo y la pureza — con resultado métrico o imperial.
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.

Frequently asked questions
Dosis (kg/ha) = plantas objetivo por m² × 10.000 × peso de mil semillas (g) ÷ (germinación % × emergencia en campo % × pureza %) ÷ 1.000. La calculadora hace la conversión de unidades; el resultado imperial se deriva del métrico.
La germinación de laboratorio se mide en condiciones ideales. En campo real se pierden plántulas por temperatura del suelo, humedad, costra, plagas y profundidad de siembra. Los descuentos de emergencia y pureza convierten la germinación de laboratorio en una dosis realista — lo que un comprador comercial debe especificar en un RFQ.
Peso de mil semillas: la masa en gramos de 1.000 semillas. Varía por cultivar, lote y calibrado. Pida siempre al proveedor el PMG certificado del lote concreto ofertado.
No. SeedMatchGroup es neutral frente a proveedores. Ayudamos al comprador a especificar la necesidad y abrimos un RFQ privado a productores cualificados para que las ofertas lleguen comparables.
Understanding the values
What each choice in this calculator means, and how the options differ in practice.
- Area and layout
- Hectares alone are not a specification. Block dimensions, corridors and packhouse share decide how much of the site actually produces.
- Scenario testing
- Change one assumption at a time and record the effect. The value of the tool is comparing scenarios, not the single first number.
Illustrative project summary
1 ha multi-span tomato house
A new commercial entrant builds a first multi-span block with fertigation, insect screens and a basic climate computer.

Indicative full greenhouse project CAPEX
USD 575K – USD 1.56M
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. Excludes land, permits, packhouse, financing costs and working capital.
Based on the published commercial greenhouse cost benchmark. Written offers require a private project review; commercial projects start from USD 250K.
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
- Local climate: temperature, humidity, radiation and wind exposure
- Growing system (soil, substrate, hydroponic) and plant density
Questions this calculator answers

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.
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.
One private brief, specialist review, private supplier research and a like-for-like comparison.
Spec gaps, MOQ, delivery, Incoterms and evidence labels for seeds, greenhouses, irrigation, fertilizers and produce.
Month-by-month schedule from concept to first harvest across 9 stages.

The ten most expensive planning and procurement pitfalls — and how to avoid them.
Procurement answers behind these numbers
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.
- Turnkey EPC vs separate equipment packages
- What belongs in a greenhouse equipment specification
- Normal payment milestones in equipment contracts
- Which Incoterms to use for greenhouse and irrigation equipment
- How long a commercial greenhouse takes from order to handover
- What is normally the owner's scope on a greenhouse project

Editorial · not a sales pitchCalculator outputs are indicative. When your numbers stabilise, a supplier-neutral RFQ turns those estimates into a consistent brief for comparing the written offers that participating suppliers provide.
The facts a complete, supplier-neutral request on this topic includes. Use it as a checklist before submitting.
- Project location, scale (hectares / m² / units) and target start window
- Crop, product category or equipment scope required
- Technical scope: structures, equipment, controls, irrigation, energy
- Delivery terms, incoterms, packaging and destination port or site
- Budget band (USD $250K+) and approval status

- Site plan, layout sketch or existing BOQ
- Any feasibility study or previous supplier quotation
Opens the RFQ Builder with this topic pre-selected so a specialist can scope it before any supplier is contacted. 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 content is provided for research, transparency and discovery only. Buyers submit one project or RFQ to SeedMatch Group; our team validates and organises it, manages any suitable supplier or manufacturer outreach, and presents the responses through SeedMatch. There is no public directory of company identities, automatic matching, direct messaging or direct buyer-supplier contact.
