Challenge Problems
Push your limits with challenges.
Question 1
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?
💡 Hint: Consider how consistent leaching can steadily decrease salinity levels.
Question 2
Discuss the economic impacts of ignoring effective leaching practices in a salinity-prone region. What steps can be taken to mitigate these effects?
💡 Hint: Reflect on how soil health directly correlates with agricultural profitability.
