What Happens To Fertilizer Nitrogen In The Soil?, W. O. Atkinson, John L. Ragland
What Happens To Fertilizer Nitrogen In The Soil?, W. O. Atkinson, John L. Ragland
Agronomy Notes
What happens to the nitrogen a farmer applies as fertilizer each spring?
First, let us consider the forms of nitrogen normally applied, and then attempt to trace what happens to the nitrogen once it is added to the soil. The average complete fertilizer contains approximately 70 percent of its nitrogen in the ammonium nitrogen form (NH4), about 10 percent in the urea form (this is quickly converted to ammonium nitrogen), and the remaining 20 percent in the nitrate nitrogen form (NO3) .

Agronomy Notes
In cooperation with Stuart Brabant, Area Extension Agent in Henderson county , four field trials with nitrogen fertilization on corn were conducted in the Ohio River Bottom area. In two of the trials where corn was followed by corn, nitrogen was applied at the rates of 0, 50, 100, 150 and 200 pounds per acre, with each treatment replicated 4 times. In the two other trials, where corn was grown following soybeans, nitrogen rates of 0, 100 and 200 pounds per acre were replicated 4 times in one field and 3 times in the other.
