  1. Welcome! The Topic For Today Is… Soil

  2. SOIL

  3. Texture: 200 • Question: • Soil texture can be defined as the relative proportions of these particles. • Answer • What are sand, silt, and clay. Back

  4. Texture: 400 • Question: • Soils with this texture have large voids between the particles and allow water and air to move freely. • Answer • What is sandy? Back

  5. Texture: 600 • Question: • Soils with this texture may shift and slide when wet. • Answer • What is silty? Back

  6. Texture: 800 • Question: • Clay particles are an important reservoir of plant food due largely to these two properties. • Answer • What are their large surface area and negative charge? Back

  7. Texture: 1000 • Question: • In samples of sand, silt, or clay with equal volumes this soil particle size will have the largest total pore space. • Answer • What is clay? Back

  8. Structure: 200 • Question: • Soil structure is defined as the arrangement of these into aggregates. • Answer • What are the primary soil particles (sand, silt, and clay) Back

  9. Structure: 400 • Question: • A soil that allows water and air infiltration, plant root penetration, and resists erosion has this kind of structure. • Answer • What is good soil structure? Back

  10. Structure: 600 • Question: • This is the most common type of soil structure in topsoil. • Answer • What is granular? Back

  11. Structure: 800 • Question: • This dark brown spongy material is important because it improves soil structure. • Answer • What is humus? Back

  12. Structure: 1000 • Question: • Name five commonly recognized types of soil structure. • Answer • What are granular, single grain, blocky, prismatic, columnar, platy, and massive Back

  13. BMPs: 200 • Question: • BMP is short for this. • Answer • What is Best Management Practice? Back

  14. BMPs: 400 • Question: • BMPs are activities that farmers, rural residents, and city dwellers can do to promote this. • Answer • What is the conservation (wise use) of soil and water? Back

  15. BMPs: 600 • Question: • This BMP is an area of vegetation along a stream, river, or other body of water that is important for water quality. • Answer • What is a riparian buffer? Back

  16. BMPs: 800 • Question: • Conservation Tillage is a BMP because it does many things. Name three benefits of conservation tillage. • Answer • What are reduces erosion, improves water quality, improves soil quality, stores carbon, reduces evaporation, improves fertility, etc. Back

  17. BMPs: 1000 • Question: • Two important aspects of an animal waste management plan are _______ and _______. • Answer • What are keeping animal waste out of the water and utilizing the nutrients in the waste to benefit the farm? Back

  18. Soil Survey: 200 • Question: • You can get a copy of a soil survey here. • Answer • Where is a soil and water conservation district office? Back

  19. Soil Survey : 400 • Question: • These maps found in a soil survey are good for comparing large areas for general land uses but are not suitable for planning the management of a specific farm or field. • Answer • What are general soils maps? Back

  20. Soil Survey : 600 • Question: • A soil map symbol tells you this. • Answer • What is the soil series name and slope class? Back

  21. Soil Survey : 800 • Question: • Most soils are given a name that comes from this. • Answer • What is the location where they were first mapped? Back

  22. Soil Survey : 1000 • Question: • The ratings in the soil survey interpretative tables indicate this. • Answer • What are the limitations of a soil? Back

  23. Soil Forming Factors: 200 • Question: • The number of soil forming factors. • Answer • What is five? Back

  24. Soil Forming Factors : 400 • Question: • This soil forming factor can be either mineral or organic. • Answer • What is parent material? Back

  25. Soil Forming Factors : 600 • Question: • This soil forming factor has a great influence on the rate of chemical and mechanical weathering. • Answer • What is climate? Back

  26. Soil Forming Factors : 800 • Question: • This soil forming factor causes soils that have developed under trees to usually have a thin O horizon while soils that develop under grasses to usually lack an O horizon. • Answer • What are biological factors? Back

  27. Soil Forming Factors : 1000 • Question: • These are the result of the action of the soil forming factors. • Answer • What are soil properties? Back
