How does fertilizer get into your water systems?
When fertilizers are applied to crops, certain amount of it remains on plants which is washed off by rain and conveyed to rivers and lakes by surface run off. Further, excessively applied fertilizers gets mixed with water and such water containing traces of fertilizers percolate down into the soil and finds way to rivers and lakes by underground streams. Furthermore, nutrients contained in such polluted water brought to rivers and lakes accelerate growth of weeds, aquatic plants causing depletion of dissolved oxygen thereby damaging aquatic eco system existing in rivers and lakes.

What are the limitations of fertilization?
Well inorganic fertilizers are known to work faster than organic fertilizers but they have their disadvantages... (1) Because they are soluble they can be easily dissolved in water and washed away. These fertilizers are known to run off into streams and rivers and cause problems to the wildlife there. (2) Inorganic fertilizers kill the microorganisms in the soil. The organisms are responsible for the breakdown of organic matter and the subsequent release of nutrients into the soil. When these organisms are killed off the soil becomes less fertile. (3) It is claimed that the chemical fertilizers when absorbed not only assist in growth but also contaminates the plants. This contamination is then passed on to us when we consume these plants.
Do synthetic fertilizers harm soil?

How did southern and northern Mesopotamia differ in terms of soil fertility?

This pollution can rob the water of oxygen, distress or kill off fish and other water depended creatures, and increase chocking weed and algae growth.
