A method of managing a farm includes preparing a farm management protocol and a code of practice and managing the farm in accordance with these documents. The farm management protocol includes instructions for farmers on the use of inputs to the farm to ensure that the outputs of the farm are of a particular quality and specification. The code of practice provides farming guidelines to ensure that application of the farm protocol will result in the particular outputs being achieved reliably. A system for monitoring the inputs and outputs of the farm is also provided to ensure that the farm management protocol is being followed and to enable changes to the protocol to be made as required.
