Fertigation System Planning

PRACTICAL GUIDE

Project context

Designing accurate nutrient injection for drip and greenhouse systems. For projects in Afghanistan, early definition of operating conditions, site access, utilities, local skills and maintenance capability helps prevent avoidable procurement changes.

Planning and specification

Water analysis, irrigation uniformity, stock-solution concentration, injector capacity and flushing practice should be coordinated. Requirements should be recorded in a clear datasheet and linked to applicable standards, inspection stages, documentation, delivery conditions and acceptance criteria.

Typical equipment and supply scope

Venturi or pump injectors, tanks, filters, valves, EC and pH meters, dosing pumps and compatible fertilizers. The final package should also consider commissioning materials, recommended spares, special tools, training, warranty support and export packing suitable for the complete transport route.

Procurement approach

Comparable bids require one consistent technical scope. Supplier deviations should be listed separately, while drawings, certificates, test reports, country of origin, delivery schedule and after-sales support are evaluated before award.
