Across
  1. 2. - A channel dug into the soil and designed to conduct surface runoff water safely to the desired location.
  2. 3. - the change in elevation for a given horizontal distance of the earth's surface often expressed as a percentage.
  3. 5. - the planting of alternating crops in parallel, narrow strips around the slope of a field. Usually to help control or reduce erosion.
  4. 8. -the probability of that a flood of a given degree of severity will occur in a known period of time.
  5. 9. -a physical structure constructed across the slope of a hill to prevent the free downhill movement of surface runoff.
  6. 13. - black or brown substance, typically at the soil surface, resulting from the decay of plant and animal matter.
  7. 16. - a layer of parent material deposited overtime at the floor of the ocean or sea that forms the basis for the subsequent development of a soil.
  8. 17. - the cultivation of a field with rows produced across the slope.
  9. 19. -the description of the ability of a land parcel to produce crops given the danger of erosion and other limiting factors.
  10. 23. - loss of soil in larger often impassible trenches or ditches resulting from runoff.
  11. 25. - any one of numerous methods of soil cultivation to control soil loss and erosion.
  12. 26. - is the process of wearing away or removal of the surface layer of anything, especially in natural resource management. This refers to the loss of surface soil to water and land.
  13. 27. - an upon-like structure built for the specific purpose of collecting surface runoff and allowing sediment to settle out.
  14. 28. -sand moved by land resulting in either removal of sand particles as in wind erosion or accumulation of sand particles as in sand dune at a beach.
  15. 29. - a crop grown primarily to prevent erosion and to improve the soil structure and tilth.
Down
  1. 1. surface layer of soil containing relatively high percentages of decomposed organic matter.
  2. 4. -layers in a mature soil
  3. 6. matter-dead plant and animal matter in various stages of decomposition.
  4. 7. - the process of breaking down rocks and minerals through the actions of weather, ice, roots, and grinding.
  5. 10. - those materials underlying the soil from which the soil was formed.
  6. 11. - the alternation of one crop with one or more other crops to promote soil conservation to improve soil structures and numerous other benefits.
  7. 12. - soil loss in small but visible tracks or traces like small gullies resulting from runoff.
  8. 14. - in a soil profile, the distance measured from the bottom edge of the topsoil to the top edge of the parent material.
  9. 15. - a ditch designed to conduct surface runoff to the desired location planted to a heavy grass, sodd to prevent erosion in the ditch.
  10. 18. -soil loss resulting from the cutting action from running surface water.
  11. 20. - with regard to soil, this refers to the relative percentage of sand, silt, and clay particles.
  12. 21. -loss of a fairly uniform layer of the soil surface often without noticeable gullying.
  13. 22. - the ability of soil to allow water to move through and of the soil structure. This is closely related to the amount and size of spaces between soil particles as well as to the absence or presence of impermeable layers under the soil surface.
  14. 24. - soil loss resulting from the action of the wind.
