Netafim Fertikit 3G PL Dosing Nutrigation System with Pump

Precision Nutrigation™ for Profitable, Scalable Crop Performance

The Netafim FertiKit™ 3G PL is a high-efficiency, fully modular fertigation dosing system engineered for open fields, orchards, and soil-grown crops where precision, scalability, and cost-effectiveness matter. Designed to inject fertilizer and acid directly into the main irrigation line, the FertiKit™ 3G optimises nutrient use with minimal waste, helping growers improve yields while reducing water, fertilizer, and energy costs.

With its integrated Grundfos booster pump, the PL model creates the necessary pressure differential to power high-efficiency Venturi injectors. This configuration ensures consistent suction and mixing, even at high flow capacities, making it suitable for a wide range of applications—from 0.1 Ha nurseries to 400 Ha plantations.

This modular system provides an ideal solution for simple applications with minimal investment. The main benefit of the system is the precise nutrition it provides, based on high stability of the fertilizer injectors. Among its features we highlight the quick-acting valves as well as the high-precision dosing channels.

FertiKIT is a very profitable solution with application in agriculture and greenhouses that allows you to optimize the application of water and nutrients based on the type of crop. The FertiKIT system offers a notable improvement in the quality and yield of the crop, lower consumption of fertilizers and energy, lower expenses, more savings and greater profitability, significantly improving the benefits of agricultural exploitation and a high yield and rapid return on investment.

FEATURES

• Modular Design: Built on a flexible platform that grows with your operation. Start with 2 dosing channels and expand up to 6 (including dual-channel options).
• Precise Dosing: Injects fertilizers or acids with flow rates of 50 to 1000 L/h per channel using Venturi-based suction—no moving parts means lower maintenance.
• Integrated Booster Pump: Equipped with a Grundfos CM5-9 (for ≤600 L/h channels) or CM15-4 (for 1000 L/h channels), ensuring reliable performance in PL configurations.
• Multi-Mode Operation: Compatible with Netafim NMC controllers or third-party irrigation systems using 24VAC solid-state relays for flexible control.
• Full EC/pH Control: Optional monitoring and adjustment for precise Nutrigation™.
• Proven Reliability: Built for harsh agricultural conditions with corrosion-resistant aluminum frame and high-quality PVC components.
• Plug-and-Play Compatibility: Easily integrates into new or existing irrigation setups, including mainline bypass or inline systems.
