Detailed explanation-1: -Compared to other layers of a typical soil profile, the amount of organic matter in the A horizon is: More. Most row crops grow best in a pH ranging from: 5.5 to 6.5.
Detailed explanation-2: -There are five soil horizons: O, A, E, B, and C. (R is used to denote bedrock.) There is no set order for these horizons within a soil. Some soil profiles have an A-C combination, some have an O-E-B, an O-A-B, or just an O.
Detailed explanation-3: -A soil horizon makes up a distinct layer of soil. The horizon runs roughly parallel to the soil surface and has different properties and characteristics than the adjacent layers above and below. The soil profile is a vertical section of the soil that depicts all of its horizons.
