Expected Behaviour

I expect that, on the Manure Management report in the Holos results, that the 'Total volume of manure (wet weight)' value would change when I change the 'Nitrogen content of manure' value on the 'Manure' tab on the Component Selection screen (for any animal group). However, if I double the 'Nitrogen content of manure' value, the 'Total volume of manure (wet weight)' estimate remains the same - the example I used was the default dairy operation. I had expected the manure volume estimate to halve when the N content value is doubled, when the 'Total manure N available for land application' value remains the same (as calculated in Eq. 4.5.2-6 for dairy cattle.

Actual Behaviour

Describe the Issue & Steps to Reproduce

  1. Add dairy cattle component
  2. Leave all settings at default and go to Results > Manure Management report > 'Total volume of manure (wet weight)' column
  3. Go back to Component Selection screen and change 'Nitrogen content of manure' value from 0.392 to 0.784
  4. Go to Manure Management report again - 'Total volume of manure (wet weight)' value remains the same when it should be about half the previous estimate
