Discussion
Consider the following statements about single and triple superphosphate.
1. Single superphosphate contains gypsum and so supplies sulphur too.
2. Triple superphosphate is roughly three times as concentrated.
3. Both are made by treating rock with sulphuric acid.
Answer: B
The first two are correct, and the sulphur in single superphosphate is a genuine agronomic benefit. The third is wrong because triple superphosphate uses phosphoric acid. The gypsum accounts for most of the difference.
