Question

Explain with suitable examples how pesticides,herbicides and industrial wastes are responsible for soil pollution

Answer 1

Industrial waste
Disposal of industrial waste is one of the major reasons for soil pollution. Industrial waste mainly consists of organic; inorganic and non-biodegradable materials. These pollutants change the physiochemical and biological aspects of the soil. Such as change in texture, mineral, bacterial and fungal colonies in the soil.
Agricultural practices
Advance agro-technology, huge quantities of fertilizers, pesticides, herbicides and weedicides are used to increase the fertility of the soil but their excessive use disrupts the soil’s physiochemical and biological property.
Soil that has been contaminated should no longer be used to grow food, because the chemicals can leech into the food and harm people who eat it.
If contaminated soil is used to grow food, the land will usually produce lower yields than it would if it were not contaminated. This , in turn can cause even more harm because a lack of plants on the soil will cause more erosion, spreading the contaminants onto land that might not have been tainted before.
In addition, the pollutants will change the makeup of the soil and the types of microorganisms that will live in it. If certain organisms die off in the area, the larger predator animals will also have to move away or die because they have lost their food supply. Thus it’s possible for soil pollution to change whole ecosystems
