This checklist of RHP EXPLAINS how the acidity behaves in an organic substrate and why it possibly deviates from the expected value

Each culture has an optimal pH value in which plants develop best. That's why it is important to adjust the pH of the substrate to the culture and to know the factors that influence the pH value. Clarity on the dynamics of the pH in the root zone is essential for achieving the best culture result. RHP has developed a checklist which explains how the pH behaves in an organic substrate and why it possibly deviates from the expected value.

Because every crop has a desired pH value in which it grows best, it is important to adjust new substrates to be developed on the culture as regards pH. Or do you want to translate the consequences of a chosen recipe to the culture situation? Various factors influence the pH during a culture: the uptake of elements by the crop, the crop stadium, liming and fertilisation. In an existing culture situation you can still steer the pH, so that it fits the culture optimally.

Each substrate has a certain pH-buffer. Because of this buffer the pH changes less quickly at adjustments. The pH-buffer can strongly vary per growing medium.

You can use the checklist ‘pH organic substrates’ that RHP has developed, when you want to compose a new substrate that has been adjusted to a culture as regards pH. You can also gain more insight which factors in a culture influence the pH and to which extent. Based on this knowledge you can examine how the pH can be steered to the optimal pH value for the culture situation.

To develop new substrates?
Do you want to develop new recipes that are adjusted better to a specific culture as regards pH? RHP gladly advises you and has also developed a pH-workshop for certified companies.
