摘要:

In a 38‐year‐old Scots pine(Pinus sylvestrisL.) stand, located in Central Sweden, the accumulation of15N‐labelled fertilizer nitrogen in the foliage was monitored for 6 years. The nitrogen sources used were double‐labelled ammonium nitrate, urea and ammonia solution. Ammonium nitrate was surface broadcast, while the urea and ammonia solution were applied by concentrated deep‐point‐placement.
