a crop farmer is deciding which kind of soil is best for growing a variety of crops. the crops will need to be able to remain somewhat damp between weekly waterings, but the soil should not be saturated the entire time.

which of the following soil types is best for the farmers crops to remain damp but not saturated?

choose 1 answer:

a clay

b loam

c sandy

d sandy loam

Explanation:

The farmer needs soil that can hold some water (to keep crops damp) but not too much (so it's not saturated). Clay has high water - holding capacity (would be too saturated). Sandy soil has low water - holding capacity (won't stay damp). Sandy loam has low - moderate water - holding capacity. Loam has moderate water - holding capacity which is ideal for remaining damp but not saturated.

Answer:

B. loam
