A farmer treats a field with calcium hydroxide to make it less acidic. When the farmer adds ammonium nitrate fertiliser to the field immediately after the calcium hydroxide, the two substances react. Why does this reaction make the fertiliser less effective?
Explanation
The correct option is A because when calcium hydroxide reacts with ammonium nitrate, it produces ammonia gas, which is released into the atmosphere, making the fertiliser less effective as less nitrogen is absorbed by the soil.
