OPF Foliar/Liquid Organic Plant Food

OPF (Organic Plant Food) is made by the Dutch company Plant Health Cure. They are worldwide market leaders in the field of mycorrhiza technology and soil biology. Their main aim is to manufacture products that make plants resistant and allow them to function better. OPF does not contain any animal matter.

PHC's approach is based on how plants function in nature. Plants naturally coexist with many useful and beneficial fungi and bacteria. This symbiosis results in mutual advantages. The beneficial soil life profits from exudates excreted by plants. In turn the soil life ensures that plants can better absorb minerals and water. It also produces hormones or induces the plant to do so; this makes the plant grow better and makes it more resistant. Mycorrhizae and soil bacteria also play an important role in disease prevention. They protect the roots, so pathogens cannot get close, and they also actively exterminate the harmful organisms.

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. Natural vegetable raw materials have low amounts of salt, reducing the risk of root- and leaf burn damage. 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. OPF is a natural product and contains no preservatives.
