Physical Properties of Soil

4. The binding of soil particles
9. The amount of water available for uptake by plants
11. The volume of water in the soil after gravitational water has drained away
15. Clay soils are susceptible to this but sandy soils are resistant
17. The squashing together of aggregates
18. Water that moves up through the soil in small pores
19. Sandy soils are susceptible to this but clay soils are resistant
20. The arrangement of particles in a soil
21. The wearing away of the top layer of soil

1. Clay soils contribute to this, sandy soils do not
2. The build up of soil particles in other areas
3. Minimum amount of water needed by plants to prevent wilting
5. Water that moves down through the soil
6. A soil of roughly equal parts sand, silt and clay
7. The proportions of sand, silt and clay particles in a soil
8. The largest particle that contributes to soil texture
10. Derived from the parent material of the soil
12. When soil particles come together they form ....
13. Used to determine the soil texture when proportions are known
14. Derived from dead plants and animals that have broken down
16. Water that is adsorbed onto the particles of soil by being attracted to the negative charges of clay particles
17. The smallest particle that contributes to soil texture
