We started FarmLogs years ago as a replacement for FarmWorks. I was fed up with the antiquated interface and having to drive to my uncle's house to access the computer it lived on. It isn't a direct replacement, but it might cover your needs and you can evaluate it for free. You would still want to use Quickbooks or some other accounting option for your taxes, but you can analyze field and crop level P&L easily in FarmLogs. You can also manage grain inventory and marketing.
