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 concentration of key nutrients such as nitrogen, phosphorus and potassium is sufficient enough to compete with commercial fertilizers.
ABoth Statement I and Statement II are true
BBoth Statement I and Statement II are false
CStatement I is true but Statement II is false ✓ Correct
DStatement I is false but Statement II is true
Correct answer: (C) Statement I is true but Statement II is false
Explanation
Statement 1 is true but Statement 2 is false.
Statement 1 is true because composting is indeed the aerobic breakdown of organic matter under controlled conditions, yielding a marketable manure.
Statement 2 is false because the nitrogen, phosphorus and potassium in compost are too dilute to rival concentrated commercial fertilizers.
Compost mainly improves soil structure, moisture holding and microbial life rather than supplying high nutrient doses.
Aerobic composting relies on oxygen loving microbes that generate heat as they decompose the waste.
It is a valued way to recycle organic waste and reduce the burden on landfills.
