Given below are two statements. In the light of the above statements, choose the most appropriate answer from the options given below.
Statement I:Composting is aerobic degradation of organic materials under controlled conditions, yielding a marketable manure.
Statement II:In such composts, the concentrations of key nutrients such as nitrogen, phosphorus and potassium are sufficient to compete with commercial fertilizers.
ABoth Statement I and Statement II are correct
BBoth Statement I and Statement II are incorrect
CStatement I is correct but Statement II is incorrect ✓ Correct
DStatement I is incorrect but Statement II is correct
Correct answer: (C) Statement I is correct but Statement II is incorrect
Explanation
Composting under controlled aerobic conditions yields a manure that can be sold to farmers.
Statement 1 is correct because the managed decay produces a stable, marketable soil amendment.
Statement 2 is wrong because compost is too low in nutrients to rival commercial fertilizers.
The nitrogen, phosphorus and potassium content of compost is far weaker than that of factory fertilizer.
Compost is valued more for improving soil structure and adding organic matter than for high nutrients.
Because it releases nutrients slowly, compost is often used alongside, not instead of, fertilizer.
