Drip Irrigation System: This irrigation system includes an arrangement of pipes or tubes with very small holes in them to water the plants at the base of roots drop by drop. This is a very efficient process as water is not wasted at all.
Question 8: What are the weeds? How can we control them?
Answer: Weeds are unwanted and undesirable plants that grow naturally along with crops. There are many ways to control the growth of weeds. Tilling before sowing crops helps in the uprooting and killing of weeds, which may then dry up and get mixed with the soil. Weedicide is a chemical that is sprayed in the field to kill the weeds.
Question 9: Explain how soil gets affected by the continuous plantation of crops in a field.
Answer: Continuous plantation of crops makes the soil poorer in certain nutrients as the crops take up nutrients from the soil. The soil becomes infertile. It does not get enough time to replenish the nutrients.
