Soil Taxonomy

1. how easily air/water pass through soil
3. wetland soil highly acidic full of peat
7. a soil of 30% silt, 35% clay 35% sand
8. dark soils best for agriculture in US grasslands
10. the ability of a soil to retain water
13. soil texture that drains well but lacks the ability to hold nutrients and is not fertile
14. little to no horizon development, very yound soil
15. soil made of 70% sand, 10% clay and 20% silt
17. soil texture with good water-holding ability & fertility that feels like flour when dry
18. the ease with which soil may be tilled
20. coniferous and acidic causing low fertility
22. the % of clay in a loam soil containing 45% sand and 35% silt
23. high in clay dries out and mixes horizons

2. rich in Al and Fe, fair horizon development
4. beginning of B horizon, slightly more horizon
5. determined by the percentage of sand, silt, and clay sized particles
6. a system to classify soils using color, texture, structure, and other properties
7. soil texture with ability to hold both nutrients and water but has poor aeration and drainage
9. a soil with a combination of sand, silt, and clay sized particles
11. low nutrient/fertility dev horizons in rainforest
12. volcanic soils rich in nutrients
16. desert soil found in Sahara Arabia and W. USA
19. subtropics with iron(Fe) making soil reddish
21. permafrost soil found in N Canada and N Russia
