Soil Water
Properties
| Question | Answer |
|---|---|
| How does pore size affect water permeability? | Larger pores fill up last but empty first. This means that sandy soils drain freely and are more prone to leaching. |
| Which soil type typically exhibits the highest capillary rise? | Silt loam due to its range of pore sizes; cracks and micropores allow rapid infiltration and movement of water between layers. |
| What is meant by the term "ponding"? | Pores in a clay soil swell shut when wetted. |
| What situation might give rise to "capping"? | Heavy rainfall on bare silt (e.g. seed bed). |
| What term is used to define the amount of water that a given soil can hold for crop use? | Moisture holding capacity |
| What does gravitational water refer to? | Water inside larger soil pores that is free-draining. |
| What condition does a field reach when all soil pores are filled with water (no air)? | Saturation point |
| Which term refers to the speed at which water moves through the soil profile? | Permeability rate |
| Which term refers to the speed at which water enters the soil surface? | Infiltration rate |
| What are the proportions of clay:silt:sand in a loam? | 20%:40%:40% |
| What does buffering capacity mean? | Ability of soil to stop nutrient or sudden pH changes by absorption. |
| How might you describe crop condition during a summer drought? | Water stressed - demand exceeds availability |
