loss of
A
organic matter only
B
water only
C
water and organic matter
D
inorganic matter and water
medium Difficulty
Verified Correct Answer: Option C
Biological Concept & Syllabus Guide
The primary purpose of oven-drying to obtain a constant weight is to remove the moisture content (water content) in the soil and then because in the soil sample we have organic matter as well which also contributes to the weight of the soil, hence we oven-dry to obtain a constant weight. This makes option C, the correct answer.
