Made himself a sort of fertiliser (4-4)

Ross

I believe the answer is:

fish-meal

'sort of fertiliser' is the definition.
(I know that fish meal is a type of organic)

'made himself a' is the wordplay.
'made' is an anagram indicator.
'himself'+'a'='himselfa'
'himselfa' with letters rearranged gives 'FISH-MEAL'.

I've seen this clue in the Sydney Morning Herald.
