How do you calculate nitrates for your farm?

Rough guide per animal I believe is

Dairy cow = 85N
Suckler cow / Bulls / 2+ year olds = 65N
Calf <1 yr = 23N-ish
1-2 year old = 46N-ish

Add them all up and divide by your hectares

So if you've 100 dairy cows, 1 bull, 60 calves on 60 hectares;

(100*85 + 1*65 + 60*23)/(60 hectares) = 203 N per hectare

893bet

Does artificial N get added to that 170 figure?

I don't believe so. A separate artificial N threshold/guide comes from the dept once you're in derogation

Here's a few numbers that might help.

Calf <1 - 24
1-2 years 57.

If you are with the ICBF you can look it up they do it monthly for your herd. They also have your projected yearly total. As you get to the.last 2-3 months you just do your own projections and export any slurry you need to
