Harmful Effects Of Chemical Fertilizer
Plants require a number of soil nutrients like nitrogen, phosphorus and
sulfur for their growth. But, soil nutrient levels can decrease over time
when crop plants are harvested, as nutrients are not returned to the
soil. Hence, these essential nutrients needs to be compensated either
through the natural process of decomposition, when plants die and
decay, and the nutrients extracted from the soil return to the soil or by
the easy means of adding fertilizers.
Fertilizers are substances used to add nutrients to the soil to promote
soil fertility and increase plant growth. Today fertilizer has become
essential to modern agriculture to feed the growing population. Use of
fertilizers, especially, the chemical fertilizers has brought in blessings on
humanity, which helped contain hunger and death in different corners
of the world. Though chemical fertilizers increase crop production; their
overuse has hardened the soil, decreased fertility, strengthened
pesticides, polluted air and water, and released greenhouse gases,
thereby bringing hazards to human health and environment as well. It
has already been proved how chemical fertilizers pose serious challenges
to the balanced and sustainable growth. Accordingly, scientists and
researchers are seen arguing in favor of organic fertilizers as the best
solution to avoid soil pollution and many other threats to environment
