Ali the Farmer is an agriculturalist located north-east of the Al Kharid Palace. He can be found walking around the area once players have completed all three of Ali Morrisane's errands in Rogue Trader.
He currently has no role in any quest or any skill. There are two dialogue options when talking to him, but they both lead to practically same conversation. He speaks about farming in Al Kharid mentioning the nearby cactus patch. He also says he is about to set up a local farming store. However, supplies for his shop weren't yet delivered, so he is currently unable to provide any gardening tools or seeds. Ayesha has since filled this duty.
