Farming business needs a new logo

This is what Yongala AG was looking for in their logo design

We are an Australian farm business growing cereal crops (wheat, barley, canola, hay).
We require a simple, modern logo to be placed on paperwork, merchandise (shirts/hats) and places like the sides of trucks.
It would be nice to have some sort of symbol or initials (YA) that can be disconnected from the words "Yongala AG" that still conveys our business.
Happy to give creative freedom for the design.
A double headed wheat plant was once found on the farm (quite rare), perhaps this could be used in the design as a sign of prosperity. Read more
