Soil Review

2. Low to no organic matter in this layer, has a rocky texture.
6. Soil color with approximately 3.5 percent organic matter
8. Finest particles of soil texture
9. Soil color with approximately 2.5 percent organic matter
11. Vertical cross section of soil
12. Largest soil texture that feels gritty
14. Soil transported by air
16. Small, porous aggregates that tend to be somewhat rounded in shape
18. Broken down by chemical, mechanical, & biological actions
20. Soil that brought to an area through erosion - wind, water, glaciers
22. Consists of aggregates in which are longer vertically than horizontally with flat tops
23. Soil color with approximately 1.5 percent organic matter
24. Water soaks into this soil texture well to form clods
25. Consists of aggregates clinging together in nearly square or angular blocks having sharp edges
26. Highest producing horizon with the most organic matter

1. Mixture of rock, minerals, and organic matter
2. Consists of aggregates in which are longer vertically than horizontally with round tops
3. Soil color with approximately 2 percent organic matter
4. Decaying plants and animals
5. Groups of soil particles that bind to each other more strongly than to adjacent particles
7. Also known as the subsoil
10. Soil transported by water
13. Natural breaks in this soil are horizontal rather than vertical
15. Unweathered material that soil is formed from
17. Soil color with approximately 5 percent organic matter
19. This represents a soil condition consisting of same sized particles with no pore space between them.
21. A lack of fine particles or organic matter means that there are not significant forces to hold sand grains together.
