important additions to potting soil TO REALISE THE RIGHT BasE fertiliSation OR STORAGE FERTILISATION for the potting soil
Potting soil fertilisers contain both main- and trace elements, and are especially composed to realise the right start fertilisation of storage fertilisation.
Europe and others.
Mineral base fertilisers are especially composed for the first fertilisation of a substrate mixture. In addition also supplementary singular fertilizers have been allowed under RHP quality mark. As storage fertilisation there are CRF (controlled release fertilizers) and organic fertilizers. Dependent on the substrate mixture and the wishes of the grower a choice is made for the basic fertilisation and if desired for fertilisers with a controlled release.
RHP goes further than legislation. RHP records specifications for contents of elements in fertilisers for certified products. At CRF fertilisers, classification occurs before the release.
