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 oreder 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.
