NEW CLASS OF PHOSPHATE
High Aluminium Content
The first substantial shipment of 4000 tons of a new class of phosphate is expected to arrive in New Zealand early next year. It is an aluminium calcium phosphate with a high proportion of aluminium in its composition. This fertiliser is said to belong to a type which has not hitherto been employed in agriculture anywhere to any great extent It is mined in French West Africa and shipped from Dakar after furnace treatment A shipment of 500 tons was brought to New Zealand in February last year, and it is understood that it was available to farmers at nearly £3O a ton. It is claimed that this fertiliser has a content of about 34 per cent of water-insoluble phosphoric acid, and its high phosphate content represents savings in transport and spreading costs. No official data are available from official trials in New Zealand as to how it measures up to the other phosphatlc fertilisers available for grassland topdressing.
