How do I compare farms?
The long-term mean NPP can be used for broad comparisons.
If the long-term mean NPP for one farm is higher than another, it has grown more plant matter.
Does NPP work when comparing cropping farms such as wheat farms with other wheat farms?
NPP is a good way to compare like farms across any areas. If a cropping farm in Victoria has a higher NPP than a cropping farm in Western Australia, then it produces more grain.
If a dairy farm in Victoria has a higher NPP than a cropping farm in Victoria, then it produces more plant matter (grass).
