Fertilizer container, for example, hot (6)
I believe the answer is:
potash
'fertilizer' is the definition.
(I know that potash is a type of fertilizer)
'container for example hot' is the wordplay.
'container' becomes 'pot' (pot is a kind of container).
'for example' becomes 'as' (I've seen this in other clues).
'hot' becomes 'h' (abbreviation eg on taps).
'pot'+'as'+'h'='POTASH'
(Other definitions for potash that I've seen before include "Compound used in agriculture and industry - shop at (anag)" , "Agricultural chemical" , "Alkaline compound" , "The strange pathos of a potassium compound" , "field dressing" .)
