摘要: Abstract Natural 15N abundances (δ15N) in plant and soil can be used as a powerful marker to reveal the history of N fertilization. To investigate whether fertilizer source timing fertilization leave specific δ15N signals tissue inorganic N, Chinese cabbage (Brassica campestris L. cv. Maeryok), one most popular vegetables Asia, was grown pots for 60 days with single or split applications organic (composted manure; δ15N=+16.4‰) (urea; δ15N=−0.7‰). Seven treatments were studied: (1) basal compost (2) urea; (3) urea application followed by an additional (at 40 after transplant, same below) (4) application; (5) (6) (7) no Regardless time application, treated higher (>+9.0‰) than that (
