RFID In Agriculture - best practice


A cotton grower collective here in Australia has just finished their RFID "Research Project", and decided that it was enough of a success to go to full deployment next growing season (April '12).

They have asked me to find out if their approach is "best practice", so I'm wondering: What - if anything - have we deployed with other agriculture or primary producers for RFID elsewhere around the world?

Thanks in advance!
