In sand culture experiments with peas, in addition to a basic PK dressing, N as K15NO3 was applied at 4.5, 45.0 or 90.0 p.p.m. with or without Mo at 0.15 p.p.m. The 15N concentration in the dry matter of the aerial parts was directly related to the mineral N rate during the growth period, whereas with the total N concentration this relationship lasted for only 36 days after emergence.
