Calculation error - All: Limestone fertiliser
There is an error
with the fertiliser calculation which appears to be related to limestone. When
you select limestone fertiliser and vary the unit selection you see that the
soil/fertiliser emission amount in the results tab data table does not vary.
We are still in
the process of investigating the scale of this issue and will update you here ASAP. Until then, please use caution around your soil emission results when
liming. We are not yet certain whether simply multiplying the soil-emission
from liming with 1000 when the amount was provided in tonnes per ha (or per
acre) covers all scenarios of this bug. Also, care should be taken not to apply
this multiplication solution to the production emissions, which are not
affected by this error.

Why do I get an error message when I use “compose your own” fertiliser saying “Total N entered does not match calculated total”?
The % of total N entered in the top row must be the sum of %N entered for nitrate, ammonium, and urea (e.g. if 30% N comes equally from ammonium & urea, it’s 15/0/15% ). Please correct the values.
