Map — volunteers recalled it on crop-growing estate (10)
I believe the answer is:
plantation
'crop-growing estate' is the definition.
(site for growing crops)
'map volunteers recalled it on' is the wordplay.
'map' becomes 'plan' (I've seen this in another clue).
'volunteers' becomes 'TA' (abbreviation for Territorial Army).
'recalled' is a reversal indicator.
'it' backwards is 'ti'.
'plan'+'ta'+'ti'+'on'='PLANTATION'
(Other definitions for plantation that I've seen before include "Coffee-growing estate" , "Cotton, slave, estate" , "land for crops" , "growth area" , "settlement" .)
