RHP has organised a technical meeting about organic fertilizers for RHP certified companies on December 13th in the World Horti Center. What are the most important points of attention? A brief summary…
During the meeting RHP has shared knowledge about the application of organic fertilizers in substrates and among other things has showed a demo of a bio assay with organic fertilizers.
RHP research has shown that the most important aspects to consider when applying organic fertilizers in substrates are the following:
In addition, the interactions that can occur between all these aspects are important. The interaction between these aspects can reinforce or weaken each other. Interactions that can occur are for example:
the amount of organic Nitrogen that ammonifies in a short time
and the presence of nitrifying bacteria
and the start pH
and pH buffering
and the temperature
and crop sensitivity and development
and the stage of the mineralization process.
Next year, RHP wants to set up a procedure and a standard for RHP Bio substrates with the Product Group Horticulture. Organic growers and organizations will be involved.
With this meeting, a first step was taken in sharing the knowledge to the RHP certified substrate producers. With the new insights, they can also inform the users about all the points of attention in the application of organic fertilizers.
Didn’t you have the opportunity to attend this meeting or would you like to download the handouts of the presentations and all the information digitally? Employees of RHP certified companies can do this at My RHP > RHP presentations.
