Q. Consider the following statements:
Crop residue can be converted into renewable energy sources, such as biofuels, or used directly for heat and electricity generation.
Incorporating crop residues into the soil elevates soil temperature, causing death of beneficial soil organisms.
Crops like cotton, sugarcane, tobacco do not generate crop residues.
How many of the above statements are correct?

[A] Only one

[B] Only two

[C] All three

[D] None

Answer: A

Notes:

Explanation –

Statement 1 is correct. Crop residue can be converted into renewable energy sources, such as biofuels, biogas, or used directly for heat and electricity generation.

Statements 2 and 3 are incorrect. Incorporating crop residues into the soil can provide several benefits for soil health. Residues help improve soil organic matter content, enhance soil structure and water-holding capacity, and promote nutrient cycling. However, burning crop residue generates heat which can elevates soil temperature, causing death of beneficial soil organisms. Crops like cotton, sugarcane, tobacco also generate crop residues.
