Patent winners at Grain SA's Nampo Harvest Day | News Article

The winners of the annual Omnia/Grain SA patent competition were announced at the Grain SA Nampo Harvest Day agricultural trade exhibition on the first day.


Omnia organiser of the Patent Competition, Piet Groenewald, says the competition is an example of how farmers sometimes battle to get the correct tools and machines to do specific jobs. He says the patents are an indication that a farmer can make something better or invent something that works for him.
