One connected baseline

Agricultural project overview — crop, greenhouse, water, fertigation, pumps and solar in one baseline

Most agricultural projects are quoted system by system, so each supplier invents its own assumptions. This page does the opposite: set the crop, climate, area and technology level once, and every downstream system — irrigation demand, design flow, filtration, fertigation dosing, pump duty and solar capacity — is derived from the same numbers. That shared baseline is what makes proposals comparable.

Indicative planning figures for scoping and RFQ preparation — not an engineering design, a yield forecast or an energy-savings promise. SeedMatchGroup is an independent procurement platform and does not manufacture, install, finance or design.

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. 1. Enter site evidence

    Replace defaults with measured area, climate, water, energy, crop and commercial assumptions.

  2. 2. Test scenarios

    Change one assumption at a time and record the effect on capacity, cost, demand or return.

  3. 3. Validate the duty

    Ask the relevant agronomist, engineer or financial adviser to check the inputs and constraints.

  4. 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.

Direct answer

How do you connect crop, greenhouse, irrigation, fertigation, pumps and solar into one agricultural project baseline?

Start from the crop and the site climate: they set water demand per m² per day. Multiply by covered area and adjust for growing system and recirculation to get daily and peak-day demand. Divide peak-day demand by the daily irrigation window to get the design flow — that one number sizes the mainline, filtration bank, fertigation injector and pump duty, where pump kW = flow × head × 9.81 ÷ (3600 × efficiency). The greenhouse technology level then sets the electrical load for cooling, pumping, fertigation and automation, which converts to an indicative solar array. Every system is derived from the same assumptions, so suppliers quote against one baseline instead of seven separate guesses.

  • Design flow = peak-day water demand ÷ daily irrigation window
  • Pump kW = flow (m³/h) × head (m) × 9.81 ÷ (3600 × efficiency)
  • Fertigation dosing sized at ~1% of line flow, stock volume for one peak day
  • Baseline feeds both the greenhouse RFQ and the irrigation RFQ

Step 1 — the project assumptions

Saudi Arabia climate: Extreme summer heat (45–50 °C), very low humidity inland, high solar radiation, mild winters, scarce and often brackish groundwater.

Step 2 — the connected baseline

Each block below is derived from the block above it. Change one assumption and the whole chain moves — which is exactly what does not happen when systems are quoted separately.

Model basis: SeedMatchGroup’s published commercial greenhouse planning model for water, energy and CAPEX, with standard hydraulic and PV scoping formulas applied on top. Figures are indicative, exclude tax, duties, land and financing charges, and must be confirmed through a normalised RFQ and site-specific engineering before any budget is committed.

Step 3 — take the baseline to suppliers

Both requests are normalised against the same assumptions, so the greenhouse manufacturer and the irrigation integrator quote one project rather than two disconnected ones.

FAQ

A baseline is one set of shared assumptions — crop, climate, area, technology level, water demand, pump duty, fertigation capacity and energy load — that every supplier quotes against. Without it, a greenhouse manufacturer, an irrigation integrator and a pump supplier each invent their own assumptions and the resulting prices answer different questions.

Crop water factor, growing system and recirculation rate set daily and peak-day water demand. Peak-day demand divided by the daily irrigation window gives the design flow, and that single number sizes the mainline, the filtration bank, the fertigation injector and the pump duty. Change the crop or the climate and every downstream system moves with it.

Pump power follows from flow and total head: kW = flow (m³/h) × head (m) × 9.81 ÷ (3600 × efficiency). Choosing a pump before the flow and head are known is the most common cause of oversized pump stations and wasted energy across the project's life.

The electrical load — cooling, pumping, fertigation and automation — is converted to a daily average, then divided by the site's peak sun hours and a performance ratio to give an indicative kWp. It is a scoping figure for the RFQ, not a yield guarantee or an energy-savings promise.

No. These are indicative planning figures from SeedMatchGroup's published model, used to structure a comparable RFQ. Final hydraulic, structural, climate and electrical design remains the responsibility of the appointed supplier or engineer.

Yes. Consultants and agronomists use the baseline to frame the project with their client, keep the relationship, and use SeedMatchGroup only as procurement infrastructure — structuring the RFQ, approaching manufacturers and organising comparable proposals.

The baseline feeds the greenhouse RFQ and the irrigation RFQ. Both requests are normalised so suppliers quote the same scope, and a sourcing specialist manages the process. The service is free for buyers and SeedMatchGroup does not manufacture, install, finance or design.
