Fertiliser Origin

The original source material for a fertiliser, being derived from either organic or inorganic origins. The origin may also be referred to as natural organic and synthetic organic, with the latter distinguishing artificially created carbon-based fertilisers - primarily urea based (e.g. IBDU) with naturally occurring organic carbon fertilisers (e.g. bonemeal), and synthetic inorganic which would be a typical compound granular fertiliser. Where a product is a blend or combination of both origins then this will be called an organo-mineral fertiliser. Sometimes the fertiliser origin is termed as fertiliser group, but often many fertiliser terms are used quite loosely or liberally.
