Raw materials of natural origin contain little salt and therefore no risk of burning roots and leaves. The high level of trace elements and sugars promotes healthy soil life and ensures healthy plant growth. The amino acids in Sol Ferti can also be absorbed at low temperatures.

Due to the balance between slow-release and fast-release nitrogen elements, the effect is guaranteed for up to several weeks. About 50% of the nitrogen is released in the first four weeks. OPF is supplied without the use of preservatives.
