Question 2.
Why is leaching important?
Show hintHide hint
What happens to plants when salt levels are too high?
3Question 3.
What is the primary purpose of leaching?
- To increase crop yield
- To remove excess salts
- To improve air quality
Show hintHide hint
Think about what excess salt can do to plants.
4Question 4.
True or False: Leaching should only be performed during the growing season.
- True
- False
Show hintHide hint
Consider when crops are most vulnerable.
Question 5.
A farmer notices a salinity level of 2.5 dS/m in their field and wants to reduce it to 1.5 dS/m. If their irrigation system disperses 1000 liters of water per hour, how long should they leach to achieve the desired salinity?
Show hintHide hint
Consider how consistent leaching can steadily decrease salinity levels.
Question 6.
Discuss the economic impacts of ignoring effective leaching practices in a salinity-prone region. What steps can be taken to mitigate these effects?
Show hintHide hint
Reflect on how soil health directly correlates with agricultural profitability.
