Question

What are the negative effects of using chemicals for growing plants?

Answer 1

Explanation:

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.

Answer 2

Answer:

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.
