How many horizons are there in a soil profile?
Put the horizons together, and they form a soil profile. Like a biography, each profile tells a story about the life of a soil. Most soils have three major horizons (A, B, C) and some have an organic horizon (O).
How to make soil profile cards for soil?
Print the soil profile cards onto cardstock paper or draw your own design on a 3″ x 5″ note card. (The following files will print 6 cards per page.) Cut the cards apart. Attach a short strip of carpet tape to the card. Rolls of double-sided tape come in various widths. One-inch tape is adequate.
