In OverseerFM you are able to add custom data inputs for fertiliser, dairy factory effluent, irrigation lime and supplements. For example, if you use a customised fertiliser mix, you are able to add this in the Custom Composition tab under your profile and add the fertiliser application data in the farm analysis.
Once the custom data is added, it can be used across all the farm analyses, without having to re-enter the specific data.
To add a custom data input, click on Custom Compositions
To add the data, click on the appropriate option, and the details will need to be entered.
When entering a custom fertiliser, you are required to specify the N, P and Mg type from the dropdown lists provided, which will become available when you enter nutrient contents into the relevant field.
For elemental S content, you should declare the %age of the Sulphur content which is in the form of Elemental S.
For example, PhaSed N from Ballance, is 28.5% Sulphur, of which 100% is Elemental Sulphur;
Sulphur Super 20, from Ravensdown, is 20.6% Sulphur, of which 51% is Elemental Sulphur.
