What are the benefits of using fertilizers and pesticides for farmers?

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.

    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?

    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 ).
