Question

Superphosphate of lime is used as a fertilizer to add phosphorus nutrients to the soil.
A.True
B.False

Answer 1

We have to know that Superphosphate is the most important phosphorus fertilizer. We can derive superphosphate from the action of sulfuric acid on phosphate rock to give a mix of gypsum and monobasic calcium phosphate. Superphosphate is the commercialized mineral fertilizer that led to the progress in modern industry of plant nutrients.

Complete step by step answer:
We can define Superphosphate or superphosphate of lime, $Ca{\left( {{H_2}P{O_4}} \right)_2}$ as a compound formed by treating rock phosphate with sulfuric acid or phosphoric acid, or by combining it as mixture.
-The other names of superphosphate are single superphosphate, ordinary and normal superphosphate.
-We must remember that the Superphosphate is the major carrier of phosphate, the form of phosphorus that is used by plants. Superphosphate is one of the world's most important fertilizers. Ordinary superphosphate contains twenty percent of available phosphate; double superphosphate has forty-fifty percent of available phosphate.
-We use superphosphate primarily as a nutrient source to crops. The phosphorus component reacts in the soil same as other soluble fertilizers.
Because superphosphate has calcium sulphate content, it is very favorable for saline soils and for crops that have a high calcium demand.
-We can use superphosphate in the form of fertilizer for the addition of phosphorus nutrients to the soil. The given statement is true.
Therefore, the option A is correct.

Note:
Superphosphate should not be confused with triple superphosphate. We can produce triple superphosphate by the reaction of rock phosphate with phosphoric acid. We can commonly use superphosphate on bulbs and tubers, on vegetables, fruits, roses, blooming trees, and other flowering plants. Superphosphate is also related with changes in pH of the soil, fixation and might reduce the population of earthworm populations.
