Sediment-Submersed Macrophyte Relationships in Freshwater Systems.
Abstract
The capabilities of four species of submersed freshwater macrophytes in mobilizing nitrogen (N), phosphorus (P), and potassium (K) from three different sediments were comparatively examined in relation to their requirements for these nutrients during a 10-week period of growth under controlled environmental conditions. With all species, N and P were readily mobilized from each of the sediments and concentrated in plant shoots at levels well above those required for growth. However, the mobilization of K from all sediments was much less effective and may have limited the growth of the species considered. Sediments represent a large and important source of N and P for rooted aquatic macrophytes, but K is probably supplied to these plants primarily from the water. (Author)
