Summary A stand of mature Pinus sylvestris L. within the rain-shadow of the Grampian Mountains was found to be suffering both from nitrogen deficiency and from early spring drought, the severity of which varied cyclically. Climate affected growth directly through May rainfall and indirectly through an influence of June rainfall on nitrogen uptake. Sectional area growth responded linearly to fertilizer nitrogen at rates up to 234 kg N ha−1, this effect being independent of and additive to climate-induced changes; except for the large trees, the response was more pronounced at 7.6 m up the stem than at breast height. As growth increased, irrespective of cause, early wood percentage rose to a maximum and then declined. re]19760624
