COMPARATIVE STUDIES OF PLANT GROWTH AND DISTRIBUTION IN RELATION TO WATERLOGGING: III: THE RESPONSE OF ERICA CINEREA L. TO WATERLOGGING IN PEAT SOILS OF DIFFERING IRON CONTENT.

The article examines the effect of waterlogging in peat soils of varying iron content on the growth and distribution of Erica cinerea. The study of H. E. Jones and J. R. Etherington showed that before E. cinerea died in a waterlogged soil, the iron concentration in its tissue has increased substantially. The five peat samples, which were used in the pot culture experiments, were collected from different bog types including the Trelleck Bog in Monmouthshire, Wales and the Fountains Fell in West Riding in England. To determine the total iron content of the peat soils, the sodium carbonate fusion method was utilized.
