Nutrient Water Pollution
An imbalance in the natural nutrient content of water. Bodies of water naturally contain nutrients such as phosphorus and nitrogen which are essential to plant growth.
Nutrient Pollution: Contamination of water resources by excessive inputs of nutrients. In surface waters, excess algal production is a major concern.

The uptake of water or dissolved chemicals by a cell or an organism (as tree roots absorb dissolved nutrients in the soil).
absorption factor. The fraction of a chemical making contact with an organism that is absorbed by the organism.
saprophyte plants that obtain their energy and nutrients from dead organic matter.
saturation, zone of place lying below the water table where the pore space is saturated with water under pressure greater than that of the atmosphere.
Parasite An organism that obtains its nutrients from one or a very few host individuals causing harm but not causing death immediately.
Fertility - the quality that enables a soil to provide plant nutrients, in adequate amounts and in proper balance, for the growth
of specified plants when light, moisture, temperature, and other growth factors are favorable.
El Nino An irregular variation of ocean current that from January to March flows off the west coast of South America, carrying warm, low-salinity, nutrient-poor water to the south.
Many are decomposers which obtain nutrients needed for survival by breaking down complex organic compounds in the tissues of living or dead organisms into simpler inorganic nutrient compounds.
By means of photosynthesis, they use solar energy to convert water, nutrients, and carbon dioxide into usable biomass. Plant growth can be limited by a number of factors, including soil fertility, water, temperature, and carbon dioxide concentration.
Using photosynthesis, they can use the sun's energy to convert water, nutrients, and carbon dioxide into usable biomass.
In practice, farmers build up nutrients in the soil using compost, agricultural wastes, and cover crops instead of synthetically derived fertilizers to increase productivity, rotate crops, weed mechanically, ...
Agricultural Best Management Practice: Ag BMPs improve water quality by reducing the run off of excess nutrients, top soil or animal waste from agricultural land.
These are forms of diffuse pollution caused by sediment, nutrients, organic and toxic substances originating from land use activities which are carried to lakes and streams by surface runoff.
Compost - Process by which food scraps from a home or business are disposed of naturally to produce toxin-free and nutrient-rich fertilizer for gardening and other uses.
Many use cane juice to sweeten, because it is less processed but has many of the nutrients found in sugar cane. Others add no sweetener and instead let the real fruit ingredients do the job.
El Nino - A condition caused by the decrease in atmospheric pressure over the Eastern Pacific Ocean, weakening the prevailing westerly winds and resulting in warm waters and less nutrient replacement from cold, ...
The process is characterized by development of an environment rich in nutrients and consequent proliferous plant production.
tertiary treatment An advanced stage of wastewater treatment designed to remove nutrients or other constituents remaining after secondary treatment.
Algae: Rootless plants that grow in sunlit waters in relative proportion to the amounts of nutrients available. They can affect water quality adversely by lowering the dissolved oxygen in the water.
Algal Blooms - Rapid growth of algae on the surface of lakes, streams, or ponds; stimulated by nutrient enrichment.
Enrichment: The addition of nutrients (e.g., nitrogen, phosphorus, carbon compounds) from sewage effluent or agricultural runoff to surface water, greatly increases the growth potential for algae and other aquatic plants.

endangered: a species which is in danger of extinction throughout all or most of its range.
biochar: biomass burned in a kiln using an airless burning technique that locks in the carbon instead of releasing it. The biochar is then buried and will return nutrients to the soil and store carbon for more than 100 years.
