Across
  1. 2. A vertical section of the soil at a particular place
  2. 6. the practice of plowing around or across a slope rather than "with" the slope
  3. 7. The wind-blown parent material of soil
  4. 9. An area measurement of land used in the United States
  5. 11. A way of expressing the acidity and alkalinity of soil
  6. 16. The practice of building building earthen ridges or embankments that slow the rate of water runoff
  7. 17. The practice of planting crops in strips, which slows down the speed of the wind and rate of water runoff
  8. 20. The action of water soaking into the soil after precipitation or irrigation
  9. 21. Well-decomposed organic matter
  10. 22. The thin layers pf water that coat soil particles
  11. 23. In land surveying, on east-west line
  12. 24. all characteristics of a site, such as terrain, creek, and climate
  13. 29. the process of capturing and storing atmospheric carbon in the soil on a long-term basis
  14. 30. The downward pull of gravity on water after infiltration
  15. 31. Soil high in mineral content; soil with 6 to 12 percent organic matter
  16. 32. The amount of various salts in the soil
  17. 33. A system of describing land in which a known starting point is used to establish and indicate lines forming boundaries of property
  18. 36. Soil that is nearly equal amounts of sand, silt, and clay
  19. 40. The process of measuring and making real property
  20. 41. The material from which soil develops
  21. 42. The water that fills cracks and air spaces between soil particles
  22. 43. The classification of agricultural land on the basis of its productive capability
Down
  1. 1. A written statement of the boundaries of land and its location in relation to other land
  2. 3. The outer layer of the earth's surface; the natural medium in which plant roots grow and obtain nutrients
  3. 4. Salt in the soil saltiness from irrigation water
  4. 5. The limit or line of land
  5. 8. The arrangement of the soil particles into shapes or pieces in undisturbed soil
  6. 10. A thin layer of water that sticks to soil particles and does not move about
  7. 12. A human-made system for moving excess water from land through open ditches and underground drain tiles or tubes
  8. 13. Soil high in organic matter; soil with more than 20 percent organic matter
  9. 14. The depth of the natural level of free water below the surface of the earth; point in the earth where all the spaces are filled and no more water can be held; natural level of free water below the surface of the Earth
  10. 15. In surveying, a true north-south line
  11. 18. The movement of water through the soil
  12. 19. A method of describing land based on two fixed lines that are at right angles to each other
  13. 25. The practice of covering the soil with a layer of protective material
  14. 26. Erosion caused by people disturbing the natural cover of the land
  15. 27. The group of activities in which the surface of the land is shaped so it is more more productive
  16. 28. A distinct layer of soil materials; one of the four layers of materials from the soil surface down several feet
  17. 34. The physical condition of the soil
  18. 35. The cropping practice in which seed is planted with very little plowing
  19. 37. A layer of the B horizon, or subsoil, that is hard and compacted and restricts water percolation and plant root growth
  20. 38. The practice of alternately planting different crops that use different soil nutrients on the same land
  21. 39. The proportion of sand, silt, and clay in the soil
