Essay On Fertilizers

People get their nourishment from plants and animals where plants get most of their nutrient requirements from air, water and the soil. It is important to note though that not many soils provide all the essential nutrients needed by the plants. Soil nutrients are usually depleted by poor agricultural practices, forest clearing and the uncontrolled grazing of livestock.

Long-term use of chemical fertilizer can also change the soil pH (Day, 2008). Synthetic Fertilizers are widely used in forms to produce and maintain the supply of food. Thus, this makes the crops less nutritious.

More than half of the total yield of production is out of synthetic fertilizers which contain nitrogen, potassium, sulfur, calcium, and magnesium and so on. Humans tend to use too much Synthetic fertilizers to meet the global demand of food. Although these mentioned chemicals and minerals help boost the production of food, this has its negative side effects in the long run. Some of the negative effects of synthetic fertilizers are the following:

a.) It depletes the quality of soil where in it imbalances the acidity level of the soil that will lead to do a soil test every after three years to track whether you are using the right soil pH.

b.) It affects human’s health due to the chemicals such as the nitrates and phosphates that may lead to some serious
