I natter about fertiliser (7)

I believe the answer is:

nitrate

'fertiliser' is the definition.
(I've seen this before)

'i natter about' is the wordplay.
'about' indicates an anagram.
'i'+'natter'='inatter'
'inatter' anagrammed gives 'NITRATE'.

(Other definitions for nitrate that I've seen before include "Tear tin up for fertiliser" , "following 28 [SILVER]" , "Compound" , "Natural or synthetic fertiliser" , "Fertilizer" .)

I've seen this clue in The Mirror.
