. Throop and Hanson (1997 ) used 15 N-enriched ammonium sulfate to study N absorption and found that N derived from fertilizer applied in April, August, and September was mostly stored in roots. These results showed that late bloom to fruit development is

The ratio of labeled fertilizer nitrogen (N) divided by the amount of total N is a convenient expression for evaluating the amount of N that is derived from fertilizer. The slope of the regression line for the relationship between total N and
