How do pesticides and fertilizers affect the soil?

How do pesticides and fertilizers affect the soil?

The more pesticides stay in soil the more is the shift in microbial population. With the increase in inorganic content of soil the microbes in soil decrease. The chemical compounds present in fertilizers and pesticides lower the pH of the soil.

How does pesticides affect the soil?

Pesticides can linger in the soil for years or decades after they are applied, continuing to harm soil health. The reviewed studies showed impacts on soil organisms that ranged from increased mortality to reduced reproduction, growth, cellular functions and even reduced overall species diversity.

How do pesticides and fertilizers contribute to increasing soil pollution?

Regular use of chemical fertilizers, pesticides will decrease the fertility of the soil at a rapid rate and alter the structure of the soil. This will lead to decrease in soil quality and poor quality of crops.

How does fertilizer affect the soil?

The synthetic chemicals in the chemical fertilizers adversely affect the health of naturally found soil micro-organisms by affecting the soil pH. The use of chemical fertilizers also jeopardizes the health of bacteria that fix the nitrogen balance in the soil.

How do pesticides cause soil pollution?

Thus, due to many different human activities such as overuse of pesticides the soil will lose its fertility. Moreover, the presence of excess chemicals will increase the alkalinity or acidity of soil thus degrading the soil quality. This will in turn cause soil erosion. This soil erosion refers to soil pollution.

Why is using fertilizer and pesticides harmful to the environment?

Impact on environment Pesticides can contaminate soil, water, turf, and other vegetation. In addition to killing insects or weeds, pesticides can be toxic to a host of other organisms including birds, fish, beneficial insects, and non-target plants.

What is the negative effect of excessive use of fertilizers and pesticides on the soil?

Excessive use of fertilizers and pesticides by farmers in agriculture to enhance crop yield is detrimental to environment and human health. Fertilizers and pesticides use has led to the problem of air, water and soil pollution.

What are the harmful effects of using fertilizers?

Harmful Effects of Chemical Fertilizers

• Waterway Pollution. Water polluted by chemical fertilizers.
• Chemical Burn. Chemical leaf scorch can cause the plant to wither and die.
• Increased Air Pollution. An ice berg melting due to increased water surface temperature.
• Soil Acidification.
• Mineral Depletion.

How does the use of fertilizer affect the environment?

The over use of Chemical fertilizer has resulted to Hardened soil, Decreased in Fertility, low soil quality, increased used of Pesticide and Herbicide, Polluted air and water, and also produces Greenhouse Gasses.

How are pesticides harmful to plants and animals?

Pesticides are found as common contaminants in soil, air, water and on non-target organisms in our urban landscapes. Once there, they can harm plants and animals ranging from beneficial soil microorganisms and insects, non-target plants, fish, birds, and other wildlife.

Which is the second cause of soil degradation?

Although chemical fertilizer has been a blessing to humanity in the past, today Chemical Fertilizer has been determined to be the second cause of Soil Degradation after soil erosion (Tetteh, 2015).

How does lack of organic matter affect soil?

The absence of Organic Matter in the soil has made it hard for the Chemical Fertilizer to be retained within the Soil. The chemically damaged soil has affected the CEC (or Cation Exchange Capacity) of the soil, the storing of nutrients and nutrients exchange capability, has also diminished as the organic matter drops.
