Document Summary
Increased fertilizers, increased machinery that allows the work to be done faster, and in a more time efficient manner. Eutrophication due to runoff from agricultural land, large inputs of sediments and nutrients are deposited into the streams and rivers. Input of nutrients from managed systems increases productivity of surface waters. This large productivity results in a large input of dead organic matter to decomposers (primarily bacteria) which results in an increased oxygen uptake by the decomposers in order to decompose all of the matter through respiration. This high nutrient and low oxygen levels can result in fish kills and a general reduction in animal life. A lot of dead organisms and sometimes there are morphological transformations. Also there is the loss of a lot of potentially suitable habitat. Nitogen pollution of groundwater and human health concerns nitrate fertilizers often contaminate wells for drinking water. High concentrations birth defects, cancer, nervous system impairments, and.
