Soil Review

2. Also known as the subsoil
3. Finest particles of soil texture
7. Broken down by chemical, mechanical, & biological actions
8. Soil color with approximately 1.5 percent organic matter
9. Low to no organic matter in this layer, has a rocky texture.
10. Highest producing horizon with the most organic matter
12. Soil transported by air
14. Consists of aggregates clinging together in nearly square or angular blocks having sharp edges
16. Soil transported by water
18. This represents a soil condition consisting of same sized particles with no pore space between them.
22. A lack of fine particles or organic matter means that there are not significant forces to hold sand grains together.
23. Largest soil texture that feels gritty
24. Water soaks into this soil texture well to form clods
25. Groups of soil particles that bind to each other more strongly than to adjacent particles
26. Consists of aggregates in which are longer vertically than horizontally with round tops

1. Vertical cross section of soil
4. Soil color with approximately 2 percent organic matter
5. Soil color with approximately 3.5 percent organic matter
6. Unweathered material that soil is formed from
8. Soil color with approximately 5 percent organic matter
11. Decaying plants and animals
13. Soil that brought to an area through erosion - wind, water, glaciers
15. Natural breaks in this soil are horizontal rather than vertical
17. Soil color with approximately 2.5 percent organic matter
19. Mixture of rock, minerals, and organic matter
20. Consists of aggregates in which are longer vertically than horizontally with flat tops
21. Small, porous aggregates that tend to be somewhat rounded in shape
