The organic base of OPF consists of plant based raw materials with high levels of natural sugars. Specific fermentation processes upgrade the organic materials to an excellent fertilizer. The high content of trace elements and sugars supports a healthy soil life and provides healthy and stable plant growth. The amino acids in OPF originate from plants and are therefore easy to absorb, even at low temperatures. The balance between slow and quick released nitrogen elements ensures an effect of up to 3 weeks. OPF is a natural product and contains no preservatives.
OPF liquid has been greatly improved
At PHC we are constantly working on product development to optimize our products. OPF liquid fertilizers are now processed at 200 micron particle size. This has significantly improved the sprayability, making OPF liquid fertilizers suitable for use in practically all spray systems. An additional advantage is an even better stability of the formulation. The high concentration of vegetable amino acids and the specific composition of minerals make OPF a good choice in the tank mix.
Minimum dilution with water 1:20, 600-1000 liter water/ha. Spray diluted or mixed product within 4-6 hours. Perform a test spraying on sensitive crops. Do not mix with copper fertilizers.
Used raw materials are extracted from commonly grown crops, possibly resulting in residue. For fertilization in tomato cultivation, OPF 7-0-2 is recommended.
