Effects of Manure and Fertiliser on Soil
Effects of Manure and Fertilizers on the Soil:
We know that soil provides the most suitable base for agriculture. By the repeated growing of plants, the essential nutrients get depleted in the soil and hence the fertility of the soil is reduced considerably. The excessive use of chemical fertilizers degrades the quality of the soil in the long run. This also leads to water pollution. For example, excessive use of nitrogenous fertilizers makes the soil and water rich in nitrates. Such water becomes unsuitable for drinking. Besides, when this water flows into rivers, lakes and ponds nearby, it encourages the prolific growth of algae and thereby reduces the amount of oxygen dissolved in water. Such water then becomes unfit for the survival of aquatic life. This process is called eutrophication.
