By default, the model assumes the crop is harvested and fed to the animals in the month it is harvested.
When the defoliation is entered into OverseerFM there is an option of Crop stored prior to feeding out. Select this option if all or some of this crop is stored and fed out in subsequent months. If this option is chosen and the maize is fed to animals on a structure or to animals on pastoral blocks, usage is spread evenly over the month’s animals are on the structure or grazing blocks.
If you wish to specify which months the maize silage is fed out you will need to export the maize crop and then import the supplement back into the farm.
If you are reporting your GHG footprint you may wish to go into the GHG input tab and override the transport defaults. The default transport distance for maize silage is 30km, unless over-ridden.
