What are the benefits of using fertilizers and pesticides for farmers?
It increases crop yield and improves poor quality land. Manure improves soil texture, recycles nitrogen and introduces essential bacteria. Pasture is improved so animals fatten up quicker. Once marshland is drained, fertilisers can help reclaim that land for pasture.
Is the use of fertilizers in agriculture a good thing?
Fertilisers provide nutrients for plants. Nutrients needed in the largest quantities in agriculture are nitrogen, phosphorus and potassium. However, reducing fertiliser input can lead to reduced plant growth which can aggravate problems such as soil erosion.

High levels of nitrates and nitrites in chemical fertilizer may cause some disease like hemoglobin disorders, Alzheimer’s disease and diabetes mellitus.
What is fertilizer and its importance?
Fertilizers are food for plants. Fertilizers replace the nutrients that crops remove from the soil. Without the addition of fertilizers, crop yields and agricultural productivity would be significantly reduced. Balance nutrients for better producequality and higher yield.
How can fertilizer affect humans?
In some instances, stored or land-applied manures or nitrogen fertilizers have caused high concentrations of nitrates in water. High levels of nitrates in drinking water are known to cause methemoglobinemia (blue-baby syndrome) in human infants and other warm-blooded animals.
Why are fertilizers harmful?
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.
What are advantages and disadvantages of organic fertilizers?
Their major advantage is adding bulk to the soil. Except for manure, the organics generally release their nutrients over a fairly long period. However, the potential drawback is that they may not release enough of their principal nutrient at a time to give a plant what it needs for best growth.
What are the effects of fertilizers and pesticides?
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 two disadvantages of using fertilizers?
Fertilizers have the following disadvantages:
- They are expensive.
- The ingredients in the fertilizers are toxic to the skin and respiratory system.
- Excessive use of fertilizers damages the plants and reduces soil fertility.
- Leaching occurs and the fertilizers reach the rivers causing eutrophication.
What are the advantage and disadvantage of manure and fertilizers?
Difference between Manures and Fertilizers
| Manures | Fertilizers |
|---|---|
| It is not very rich in nutrients. | It is rich in soil nutrients like nitrogen, phosphorous, and potassium. |
| It is slowly absorbed by the plants. | It is easily absorbed by the plants. |
| It provides a lot of humus to the soil. | It does not provide any humus to the soil. |
How do pesticides affect humans?
Immediate health effects from pesticide exposure includes irritation of the nose, throat, and skin causing burning, stinging and itching as well as rashes and blisters. Nausea, dizziness and diarrhea are also common.
What are advantages and disadvantages of pesticides?

| Pesticide Pros | Pesticide Cons |
|---|---|
| Can help against parasites | Groundwater contamination |
| Using pesticides may lead to lower food prices | Can reduce populations of helpful insects |
| Fewer plants will be lost to pests | Pesticides may lead to pollination problems |
Is smelling fertilizer harmful?
Most would agree that the smell of manure is not pleasant — but describing the scent as dangerous is another thing entirely. In concentrated enough doses, the gasses that cause the smell are toxic and can cause health problems in people and animals, including asphyxiation.
What are the side effects of 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.
What are the effects of fertilizers?
What are the 3 types of fertilizers?
Nitrogen, phosphorus and potassium, or NPK, are the “Big 3” primary nutrients in commercial fertilizers.
Organic fertilizers also help improve the structure of the soil including the circulation of air, which sustains beneficial microorganisms that help release nutrients to the soil. In many agriculture areas, pollution of groundwater causes with synthetic fertilizers and pesticides.
What are the harmful effects of pesticides and fertilizers?
This leads to nutrient losses to the environment and other adverse impacts, such as drinking water contamination and eutrophication of freshwater systems and coastal zones. Some fertilizers also impact human lives as a result of unsafe storage practices.
What are advantages of fertilizers?
Advantages of fertilizers They are quick in providing plant nutrients and restoring soil fertility. They are portable and easy to transport. Plants easily absorb fertilizers. Fertilizers improve and increase the productivity of many crops such as wheat, maize, and rice.
How are fertilizers and pesticides used in agriculture?
Today, fertilizers are available in many forms, and are widely used to aid plant growth and increase crop production. Pesticides are chemicals which are used to control weeds and insects which pose a threat to crop production. If left unchecked, weeds can quickly outcompete the crop for essential light, water, and nutrients.
Why are manures and fertilizers important to grow crops?
When crops are grown one after the other, it decreases the productivity of the soil. However, this can be overcome by adding manures and fertilizers to the soil. This increases the yield of the plants and also restores the productivity of the soil. Therefore, manures and fertilizers are paramount for efficient crop production. What is Manure?
Do you have to use pesticides when growing organic food?
A common misconception when it comes to going organic is that no pesticides are used, but this simply isn’t true. For farmers and gardeners, pesticides are an important part of the growing process and help protect and maintain crops throughout the year.

Their use increased crop yields and brought on an agricultural revolution, the likes of which the world had not seen before. Synthetic fertilizers continue to have far-reaching effects,…
How are fertilizers and pesticides good for the soil?
Fertilizer comes in many forms, from chemical products to old grass clippings. By providing nutrients like nitrogen, fertilizers help plants thrive despite the threat of weeds and disease. Organic fertilizers, like manure, improve the fertility of soil by feeding microorganisms in the soil, reducing erosion and keeping soil well hydrated.
What kind of pesticides are used in organic farming?
Producers of certified organic crops avoid the use of synthetic chemicals and GE seeds for pest management; they are much more reliant on production practices such as crop rotation, tillage, adjustments to planting and harvesting dates, and the use of beneficial organisms (see the topic on Organic Agriculture ).
