Fertile Fibre Nutrients

Posted on

We produce three different nutrients: NB1, NB3 and NB5 to add to our peatfree compost. We carefully select the ingredients from reputable suppliers and each delivery or batch is analysed to make sure it conforms with Fertile Fibres strong quality control. The batch analysis is checked against our data base and alterations are changed accordingly. Any deliveries not meeting this standard are rejected. Once a new batch is made they are mixed and stored ready for use.

Nutrients: NB1

This was first produced by W.L. Dingleys for Fertile Fibre over 20 years ago. We produce our own nutrients for use in organic systems. They are a blend of ingredients that are uniquely blended for use with coir. They contain all the trace elements that a plant requires and are slow release.

NB1 is used in all Fertile Fibre Compost and included at varying amounts depending in type of compost.
