The answer is (D)
The ideal soil ratio
for solids to pore
An even split between the amount of
space is:
solids and the amount of pore space is
the ideal condition. This allows the pore
(A) 20:80
space to contain sufficient amounts of
(B) 35:65
water and air while maintaining the soil
(C) 40:60
integrity. The solids ideally are 45%
(D) 50:50
mineral and 5% organic matter.

soil classification? Loam is a combination of all three soil
(A) Sand types sand, silt, and clay. However,
(B) Silt loam without any specific designation is
(C) Clay not equally composed of all three but
(D) Bedrock rather has the least amount of clay.
,What is the The answer is (D)
difference in
magnitude of The difference in magnitude is
