The O's never recovered from an awful first fifteen minutes when they went four down before conceding another two goals before the break. An improved second half showing actually saw them draw the half 3-3 but by then, the game was virtually over as a contest.
The game began with the promise of bad weather ahead but it was raining goals in a first quarter of an hour that went a long way to determine the winners of the tie. On five minutes, Farm took the lead when a ball in from the left was volleyed home and they added a second with a deft chip two minutes later.
Luke Lipinski headed an unfortunate own goal on ten minutes and Farm made it four on fourteen minutes after breaking down the right flank. Briefly, Oldland offered a degree of resistance with Tom Hutton volleying wide and Wayne Pearce's effort blocked by the home keeper.
A lapse in defence saw Farm make it five before the half hour mark and after Pearce had curled a shot wide of the far post, the hosts made it six with a goal crafted from a short corner routine.
Danny Carter replaced Fernando Dias at half time but Farm made it seven two minutes into the second half. At last Oldland grabbed a consolation when Pearce finished well and Ali Bamford made it 7-2 when Danny Carter set him up with a clever flick.
Farm then made it 8-2 on 75 minutes before Carter set up Pearce for his second. However Farm had the last word when they scored the final goal with five minutes remaining for a comprehensive victory and a preliminary round date with Lymington Town in the next round.
