A
Drying soil in an oven.
1
Q
Field capacity:
A
Water is holding as much water as it can against the force of gravity.
2
Q
Available water (%):
A
FC - PWP
3
Q
Finer textures (clay/clay loam) tend to hold more available and unavailable water and…
A
Have a higher field capacity than coarse textures (sand/sandy loam).
4
Q
Dracys law is used to
A
Calculate the rate of flow down a slope through saturated soil.
5
Q
The flow rate will be slower through…
A
Unsaturated soils.
6
Q
Equation for Darcys law:
A
u = k h/l
k is the hydraulic conductivity of soil (m s^-1). Affected by soil texture.
