There has been lots of discussion of N holding capasity of soils, based on CEC's of the soil.
Does application method of the N source, play a role in how much N that soil can hold ?
IE: if you broadcast Urea, you are spreading the N out mostly evenly in the complete soil surface, and incorperated mostly even, in that soil profile.
The soil should be able to hold more N, with this method.
If you knife in NH3, that N source is being applyed in a fairly specifice range within the soil profile, in a sense, overlaoding that area, so the soil can't hold it ?
Same with sidedressing the vairious N sources . . .
I've never really read comments related to the application method or over application using certain application methods?
Or doesn't it matter ?
