Banded N was often better than broadcast N fertilizer
in terms of N uptake by wheat versus weeds, weed
biomass production, and winter wheat yield. Weeds
often germinate at or near the soil surface, especially in
zero tillage systems (Hoffman et al., 1998), and it is in
this situation that the greatest benefits may be realized
by physically placing N in an area of the soil profile
where crop seed, but not weed seed, is germinating
