%X <p>The ash content has been found to correlate with the fertility of peatlands. Relationship between height of 80-year-old stands and ash content of peat in topmost 30 cm layer was examined in Lithuanian conditions. On drained peatlands with ash content of peat from 3% to 8% pine stands increase in height. Ash content of peat being about 7% Scots pine (<em>Pinus sylvestris</em> L.) and Norway spruce (<em>Picea abies</em> (L.) H. Karst.) stands on drained sites are found to be of equal height. Ash content of peat more than 8–9% has no significant effect on growth of pine or spruce stands. Birch (<em>Betula verrucosa</em> (<em>B. Pendula</em> Roth.) and <em>Betula pubescens</em> Erhrh.), stands are less sensitive to ash content of peat compared with other species. Black alder (<em>Alnus glutinosa</em> L. Gaertn.) stands occurred in sites with ash content of peat more than 8–10%. The height of the stands become equal both in drained and undrained sites in the cases where ash content of peat is about 16–18%. Ash (<em>Fraxinus exelsior</em> L.) stands attain high productivity on drained sites with ash content of peat about 20%.</p>
