Derived traits allow you to calculate (derive) values based on other values using formulas.  They can be used for many types of calculations including the conversion of units (Eg. acres to hectares, Lt to mL, etc.), calculating normalised yields based on plot size, or working out the spray quantities required for a particular site.  The Derived Traits on Mobile add-on makes the power of derived traits available on mobile devices, even when the device is working off-line.

This helps ensure consistency with spray calculations and data validation when out in the field.
