Question
Given below is a conversation between two farmers - Heera and Beera.
Heera: Brother Beera, your maize crops look beautiful! They have grown pretty fast.
Beera: Yes, I have sprayed urea this time. What about you?
Heera: Well, I am still relying on good old cow dung. I am saving money on buying a tractor.
Beera: That's good. Tractor saves a lot of time and labor.
Heera: Yes, it's been very labor-intensive for me and now these weeds have come up.
Beera: Try weedicides. They are effective.
Now answer the following questions.
- List the practices which are not environment-friendly and why?
- What is the advantage of modern agriculture implements over traditional ones?
- Name one weedicide and the precaution farmers must take during its aplication.

Solution
a. Non-environmental friendly agricultural practices are:
- Fertilizers added to the soil alter the chemistry of the soil.
- They mix with the underground water, and they reach nearby water bodies.
- This leads to eutrophication.
- Pesticides sprayed also enter water bodies and kill their biota.
b.The advantages of modern agriculture over the traditional ones are:
- It offers higher crop yields.
- It reduces labor intensity, and a large area of fields can be easily maintained.
- Genetic changes such as resistance against weeds or pests can be easily achieved.
c. Weedicide:
- Weedicides are used to kill unwanted plants.
- They specifically kill unwanted plants while leaving the main crop unharmed.
- Naphathelene acetic acid is an example of weedicide.
Precautions that farmers should take during weedicide application are:
- The farmer should completely cover his face.
- He should wear fully covered clothes.
- Weedicide spraying should be done with no wind or prolonged wind.
