Default yields
Some arable crops have a yield adjustment calculation as part of their recommendation.
Therefore in order to calculate a recommendation, a yield is required.
Where a yield is provided, this is used in the calculations.
However, where one is not provided, a default yield will be used in its place.
All the crops which use default yields are listed below.
