2. Soil's cohesion, adhesion, and resistance to deformation or rupture under stress.
4. Scale indicating acidity or alkalinity, ranging from 0-14, with 7 as neutral. Below 7 is acidic; above 7 is alkaline.
8. Measure of water movement downward through unsaturated soil per unit area and time.
13. Measure of soil acidity or alkalinity expressed in pH, from ultra-acidic (less than 3.5) to very strongly alkaline (9.1 and above).
14. Water vapor emitted by land plants.
16. Measure of water's buffering capacity against acidification, its ability to neutralize acids.
17. Standing water in closed depressions on soil, removable only by percolation or evapotranspiration without artificial drainage.
18. Drainage Class: Soil wet near the surface or long enough to impair planting or harvesting, often requiring drainage installation.
20. Saturated hydraulic conductivity; water movement through saturated soil per unit area and time.
21. Substances with a pH below 7.

1. Drainage Class: Soil wet near the surface or long enough to restrict planting or harvesting unless a drainage system is installed.
3. Drainage Class: Soil with high hydraulic conductivity and low water-holding capacity, suitable for a narrow range of crops without irrigation.
5. Substances with a pH above 7.
6. Drainage Class: Soil consistently wet at the surface, inhibiting most crop growth without drainage.
7. Drainage Class: Soil with intermediate water-holding capacity, retaining optimal moisture without adversely affecting yields.
9. Rate at which water enters soil surface per unit time, typically in inches per hour.
10. Drainage Class: Soil with high hydraulic conductivity and low water-holding capacity, unsuitable for crop production without irrigation.
11. Frequency and duration of soil saturation during formation, excluding altered drainage due to human intervention or natural causes.
12. Drainage Class: Soil too wet for crop growth without drainage due to saturation, low hydraulic conductivity, or seepage.
15. Soil moisture content after gravitational water drains, typically 2-3 days post-rain; also known as normal field capacity.
19. Water evaporation from soil and transpiration from plants, returning to the air.
