Abstract/Contents: | "The absorption and assimilation of urea, NH4+, and NO3- applied to the foliage of perennial ryegrass (Lolium perenne L.) was evaluated under a controlled environment. Each form of N was spray-applied at 5 g N m-2 in 200 ml m-2 of deionized water. Uptake over a 48 hr period was estimated by a washing procedure to measure the urea remaining on the foilage, by the increase in total N in the ryegrass tissue, and by 15N analysis. Greatest absorption occurred during the first 12 hr, with a total 35 to 40% of the applied N absorbed by 48 hr. The shoots were the primary sink, although 15% of the absorbed N was translocated to the roots. Tissue data indicate that absorbed N is rapidly assimilated." |
