Eco Pond Rescue Nutrients

A Beginners Guide to Nutrients

FULL TEXT

Nutrients are substances required by all organisms for growth, and they are
found in all waterbodies. Algae and aquatic plants need nutrients in order to
grow. To help you work more effectively with waterbody managers, this circular
provides basic information about nutrients, their relationship to the growth of algae in
waterbodies, and conceptual and mathematical tools you can use to achieve water
management goals relative to algal abundance.

You’ll notice that our main focus is on algae with little mention of rooted and/or
floating leaved aquatic plants. While aquatic plants are a major factor influencing the
limnology of Florida lakes, for the purposes of this circular, we’ve chosen to concentrate
on algae and the various factors that can limit or enhance algal abundance in waterbodies.
The dynamics of larger rooted and/or floating-leaved aquatic plants (called macrophytes)
will be discussed in a separate publication.

While reading this circular we’d like for you to keep in mind that all water quality
management efforts, whether focused on nutrients or some other waterbody characteristic,
should be based on well-defined management goals. And contrary to what most of us
might think, defining management goals often takes place in the public/political arena
instead of a scientific one. However a more scientific approach, including the information
provided in this circular, can be valuable in that it can provide a perspective for evaluating
various management options and their feasibility.

Grass and Leaf Decomposition and Nutrient Release Study Under Wet Conditions

Brevard County Surface Water Improvement

Sediment carried by stormwater may reduce the ability of light to penetrate water thereby hindering the growth of marine plants; also possibly covering and smothering the plants, resulting in a die off. Leaves, grass clippings and organic matter from yards increase oxygen demands and may contribute nutrients to algae blooms that may result in fish kills. Brevard County has taken a pro-active stance to reduce sediment and nutrient contributions whenever possible through retrofitting areas that currently have little or no stormwater treatment provided. Several treatment methods currently utilized by the County include baffle boxes and stormwater inlet devices that retain these materials before they enter surface waters.

Baffle boxes often receive constant groundwater flows and retain standing water in the chambers where the sediment and debris are collected. The question has been posed whether organic constituents may leach out of the collected materials only to be carried to surface waters during the next storm event or by background flows. A significant source of nutrient input to water bodies is from grass clippings and leaves washed into drainage systems during storms. Brevard County Surface Water Improvement conducted this study to determine the nutrient release rates from grass clippings and leaves in order to better understand the chemistry and resultant pollutant loading mechanisms. The goal of this experiment was to identify variations in the concentrations of constituents, with an ultimate goal of determining a timetable for cleanout of applicable BMP structures to prevent the release of targeted pollutants.

If asked to describe a lake, most of us would probably begin by discussing the waterbody’s
more obvious characteristics such as its size, water clarity, aquatic plant growth, the color of
the water, or fishing potential — whichever characteristics are most important to us as lake
users. However, there are several other less visible lake characteristics that are just as significant,
yet rarely discussed: namely the shape and structure of a lake basin.


The study of these lake basin features is known as lake morphology and familiarity with the subject is as important to lake management professionals as human anatomy is to a physician. Just as physicians rely on their knowledge of human anatomy to understand a patient better, lake management professionals (and anyone else) can learn a great deal about how a lake functions by studying its morphometric characteristics. For example, when we know the shape and structure of a lake basin, we can sometimes predict how weather conditions or human-induced events may affect water levels in that system. This is important because, as many lake residents already know, changes in water levels can influence the water quality of their lake including the amount of algae and/or aquatic plants growing in the water, fish species and abundance, and water clarity. It can even play a role in determining the types of birds and wildlife that are
attracted to a waterbody.

Nutrients
The second essential factor in our lake management discussion is the impact of
nutrients on the aquatic ecosystem. There is a direct correlation in the level of
available nutrients and the populations of algae and aquatic weeds.
To gain a deeper knowledge it is important to understand the sources of
nutrients, how the nutrients are absorbed and broken down, and the impact
nutrients can have on water chemistry. A diagnosis of a lake’s chemical make up
can help you design a preventative program for a problem lake.
Consider the way that organic nutrients are accumulated and digested in the
lake. An organic nutrient is a carbon based compound essential to the life of a
plant. In lake ecology the macro nutrients we specifically talk of are phosphorus
and nitrogen. In fact, phosphorus has been identified as the single greatest
contributor to aquatic plant growth; one gram of phosphorous will produce one
hundred grams of algal biomass. As the nutrient level in the water increases so
does aquatic plant and weed growth, this leads to severe problems from an
environmental and aesthetic viewpoint.
