What does 'weak' structure indicate in soils?

• A. Peds are strong and hard to remove
• B. Peds are visible but cannot be removed
• C. Peds are non-observable in place
• D. Peds can be easily derived

Answer: (B)

'Weak' structure in soils typically indicates that the peds, or aggregates, are present but not strongly bonded together. This means that while you can see these peds, they are fragile and not tightly interlocked, making them difficult to remove as intact entities. The visibility of the peds suggests that some aggregation has occurred, but the weak strength means that they lack the cohesion or density found in more strongly structured soils. Thus, the characteristic of being visible but difficult to remove aligns with what is meant by weak soil structure, signifying a lack of stability in the soil aggregates.
