In 2019, a practical situation was simulated with 2 strategies, both completely with PHC products. The first is a mixing strategy, in which the additives Biovin powder, OPF granules and mycorrhizas are mixed into the potting soil. The second is a strategy in which only liquid fertilization with OPF was carried out and rhizosphere bacteria and fungi with Compete Plus were applied. The products are tested in the cultivation of Prunus, Acer, Picea and Ilex.
Result
At the end of the growing season, a root assessment was carried out looking at root intensity, quality and health. We can conclude that the objects in which the products Biovin powder, OPF granules and Mycorrhizas have been mixed (on the right in the photos below) stand out in all 4 crops.
From this test it can be concluded that it is possible to grow a high-quality and strong plant without the use of chemicals. Adding Biovin, mycorrhizas and OPF granules to the potting soil clearly has added value for rapid growth, resulting in a healthy and resilient end product that is certainly not inferior to conventional cultivation.
In the test, no spraying was necessary in the field of diseases and pests.
