Phosphorus Losses

Quality of the environment is measured and evaluated by some criteria, such as composition, and by performance. However, quality, in terms of composition and/or performance, as a factor in environment has no meaning except as it relates to some use of the environment and scale of health, happiness and aspirations of man. For example, an environment is regarded as having a lower quality than 15 years ago because of an increase in the phosphorus contained in surface water and/or a change in the species of fish present in surface waters. In terms of performance, a particular environment (watershed) is not producing enough because the soil and phosphorus losses are twice the acceptable rate. Furthermore, the composition and performance of an environment are related. Measurement of the nitrogen and phosphorus content of water helps to determine if a given water resource can be used (perform) in a particular way.
