A) The aggregation of individual soil particles in the form of lumps or clusters of soil
B) A layer of soil having distinct chemical composition, colour texture and structure
C) It is an important tool in nutrient management.
D) Loose and unconsolidated weathered materials
Correct Answer: C
Solution :
[c] The soil profile is an important tool in nutrient management. By examining a soil profile, we can gain valuable insight into soil fertility. As the soil weathers and/or organic matter decomposes, the profile of the soil changes. For instance, a highly weathered, infertile soil usually contains a light-coloured layer in the subsurface soil from which nutrients have leached away. On the other hand, a highly fertile soil often has a deep surface layer that contains high amounts of organic matter. With clues provided by soil profile, we can begin to predict how a soil will perform under certain nutrient management conditions.
