Challenge Problems
Push your limits with challenges.
Question 1
A farmer tests their irrigation water and finds an EC_{iw} of 2.8 dS/m and the saturation extract has an EC_{e} of 1.1 dS/m. Determine the leaching requirement and discuss the implications for irrigation practices.
💡 Hint: Be sure to calculate carefully and reflect on how this impacts irrigation.
Question 2
If a field is neglected for several seasons regarding leaching, and a farmer notices a significant increase in soil salinity, what steps can they take to rectify the situation using LR?
💡 Hint: Think about the relationship between leaching requirement and salinity management.
