Corn root distribution between ammonium fertilized and unfertilized soil

Earlier research has shown that in a phosphorus (P) placement experiment the amount of increase in root proliferation in the fertilized volume, F, depended on the ratio of the available soil P levels in F and the unfertilized volume, U. The objective of this research was to determine the effect of the level of nitrogen (N) in F, and U on root proliferation in F. The research was conducted using the same procedures as were used for P. Corn (Zea...
