Question
Which of the following is a long-term effect of urea
application?Solution
One of the long-term effects of urea application is that it can lead to soil acidification. Urea is a nitrogen fertilizer, and when it is applied to the soil, it undergoes a process called nitrification, where it is converted into nitrate (NO3-) ions. This nitrification process can release hydrogen ions (H+) into the soil, leading to a decrease in soil pH and making the soil more acidic over time.
