Haifa offers a unique product for Nutrigation™ in soilless greenhouses and recirculated irrigation systems.

♦ Avoid salinity build-up

Save labor

♦ Minimize pollution


Multi-K™ Reci is an innovative potassium nitrate formula with near-zero sodium. Ensuring pure, healthy nutrition, Multi-K™ Reci cuts the accumulation of sodium in the irrigation water and the growing medium. Multi-K™ Reci optimizes water use, and is highly recommended for recirculated irrigation systems.

Sodium is one of the main non-beneficial elements for plants. As it is not uptaken, it accumulates in the irrigation solution and in the growth medium, raise the salinity and might harm plants. When using fertilizers that contain sodium, growers have to wash the growth substrate in soilless systems, and to drain frequently recirculated systems in order to avoid sodium build up. This requires extra labor, and also has a negative environmental impact. 
Multi-K™ Reci cuts sodium accumulation, thus ensuring pure nutrition, optimizing water use, and saving on labor.
