“…This is confirmed by multiple regression analysis ( Table 3) which shows that all nutrient elements except nitrogen strongly depended on the nutrient content of water. Sediment, as a source of N and P, and a sink for K for Hydrilla has been demonstrated by Carignan (1985) and Barko et al (1988).…”

SUMMARVThe paper describes monthly hiomass, seasonal and annual net primary productivity and monthly and seasonal nutrient content of four submerged macrophytes in a lentic wetland situated in the campus of Banaras Hindu University. The seasonal variation of six nutrients (NO3 -N, PO,"-?, K, Ca, Mg, Na) in water is described and their mean concentrations used in multiple regression equations to examine the relationship between nutrients in water, plant biomass and nutrient accumulation in plant body. Hydrilla verticillata (L.f.) Royle, Potamogeton crispus L., P. pectinatus L. and Aponogeton natans (L.) Engle and Krause are the constituent species. Plants show rapid growth in post-monsoon and pre-winter months. All the four species showed biomass accumulation in the rainy season. The highest rate of production in the submerged zone was 0 73 g m~^ d"' and the mmimum was 0-29 g m"^ d"'. Maximum annual production of any species was 69 g m"" in P. pectinatus. In all the four species the nutrient concentration decreased in the following order: calcium > nitrogen > potassium > magnesium > sodium > phosphorus. Seasonal variation of nutrient content was dependent on the period of germination, growth and development of the species. Nitrogen, phosphorus and potassium were higher in the season of growth of particular species and calcium was higher when plants matured. There was no definite trend for sodium, though magnesium varied with species. Uptake and accumulation of nutrients in submerged plants largely depend upon nutrient concentration of water, except nitrogen which was also dependent on biomas change. Sources of nutrient for plants are both sediment and water. Translocation of potassium from the overlying water to the mud by Hydrilla plants is possible as there is reduction in potassium concentration of water around Hydrtlla.

“…This process implies that phosphorus can be translocated from shoots to roots or from roots to shoots, which has been showed in laboratory studies (De Marte & Hartman, 1974;Eugelink, 1998). If shoot absorption is debated, root uptake of phosphorus is common accepted as the mode of nutrition (Patriquin, 1972;Bole & Allan, 1978;Best & Mantai, 1979;Barko & Smart, 1981;Barko et al, 1988). Even macrophytes with limited root systems have been shown to uptake phosphorus via roots (Barko & James, 1998).…”

Changes in phosphorus content of two aquatic macrophytes according to water velocity, trophic status and time period in hardwater streams

et al. 2006

We examined the influence of water velocity, trophic status, and time period on the phosphorus content of two aquatic macrophytes. We sampled Berula erecta (Huds.) and Callitriche obtusangula (Le Gall.) from 17 oligosaprobic hardwater streams in the Alsatian Rhine floodplain of northeastern France. Sampling was conducted on a monthly basis during a 9-month period from August 1996 to April 1997. For B. erecta, phosphorus content of shoots and roots were correlated to water phosphorus content but not to sediment phosphorus content. The range of phosphorus shoot content of C. obtusangula was similar to that of B. erecta. Phosphorus shoot content of C. obtusangula was not correlated with water and sediment phosphorus content. In one stream where both species were present on the same sampling dates, shoot phosphorus content decreased when water velocity was high, particularly for C. obtusangula. Additionally, a significant effect of time period was observed for both species when the water velocities were low. The effect of water velocity was only significant from spring (April) to autumn (October) when plant phosphorus content was highest.

“…When the aquatic plants were initially established, biomass production was low, but nitrogen and phosphorus were readily available and luxury uptake occurred. This Barko et al (1988) observed that in repeat growth studies on the same sediment that nitrogen was depleted from the sediment resulting in growth reduction of Hydrilla.…”

Abstract. Nickel tailings were deposited between 1978 and 1988 in Falconbridge's New Tailings Area located northeast of Sudbury, Ontario, Canada. In 1996, construction of a new dam and dredging split the site into an Upper Terrace (56 ha) and a Lower Terrace (30 ha) to facilitate flooding. Water covers minimize the oxidation of acid generating tailings but some oxidation and release of metals may still occur. The effectiveness of a water cover could be improved with aquatic plant establishment to control tailings resuspension, remove metals from the water column and develop an organic layer to consume oxygen and support sulphate-reducing bacteria.In the New Tailings area the natural development and changes in the aquatic plant community over the five years since flooding was monitored. In 1999 and 2001 aquatic plant distribution was assessed at 121 plots along 5 transects across the Lower Terrace. Every 10 m along each transect a 0.25 m 2 quadrat was established from which aboveground biomass was harvested and samples were analyzed for nutrients.In the Lower Terrace, Potamogeton pusillus and Chara were the dominant aquatic species. In 1999, 88 plots contained aquatic plants, which increased to 113 by 2001. Over the same period, mean biomass increased from 40.2 to 103.0 g DW/m 2 . Biomass decreased, however, at 22 sites from 166.3 g DW/m 2 in 1999 to 74.6 2 g DW/m 2 in 2001. Potamogeton pusillus tissue nitrogen and phosphorus concentrations decreased from 2.18 % and 0.20 % to 1.43 % and 0.12 % with 1.3 % and 0.13% being the critical concentrations that indicate potential deficiencies. The nitrogen phosphorus ratio is typically 7 but in the Lower Terrace is 12.9 indicating that phosphorus is more limiting than nitrogen.
