OPF 4-2-8

Liquid vegetable fertiliser

The organic basis of OPF consists of vegetable residual flows with high levels of natural sugars. By means of a special fermentation process, the vegetable residues are upgraded to an excellent fertiliser. The high content of trace elements and sugars supports healthy soil life and provides for healthy plant growth. The amino acids in OPF can be easily absorbed even at low temperatures because they originate from plants. Because the product contains a variation of slow and fast releasing nitrogen elements, it has an effect of 3 weeks. OPF is a natural product in which no preservatives have been used.

Improved OPF fluid processability

At PHC we are continuously working on product development to optimise our products. OPF liquid fertilisers are now processed at 200 micron particle size. This has significantly improved its sprayability, making it compatible with virtually 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 litres/ha. Spray prepared product within 4-6 hours. Perform a test spray on sensitive crops. Do not mix with copper fertilisers.

Raw materials used are obtained from conventional crops, therefore residues may occur. OPF 7-0-2 is recommended for fertilisation in tomato crops.

For the recovery of plots or crops in poor (bio) condition, an additional dosage may be necessary. Consult your product representative for tailor-made advice.
