    Thanks pedigree, waiting for the ground to dry up a bit here again after all the rain the past week. Then all the grazing is getting a hit of can/net nitrate. Local co-op took 10 days to deliver. Think I'll collect next time.

    Lads,

    With high PH ground, 7 ish, does it matter if you use CAN or urea? I know you can't use urea after applying lime but is it less effective with high PH?

    I'm thinking urea would be a better alternative due to can having calcium included.
    Good question and I'm curious myself.
    Hopefully the mighty pedigree will be along again.
    What kind of ground are you on? It's usually low PH levels that occur.
    After a quick Google, apparently sulphur will lower PH levels.

    Yea it's more prone to volatilization into ammonium and carbon dioxide and be lost to the atmosphere with higher soil pH and higher temperatures if it's not washed into the soil.

    Handy little chart here from the University of Minnesota.
