Soil Liquid Limit

Description

Function to determine the soil Liquid Limit by using the Sowers (1965) method.

LL = θ * (n / 25) ^ {0.12}

.

Usage

 liquidlimit(theta, n) 

Arguments

theta	the soil mositure value corresponding to n drops.
n	the number of drops.

Value

The soil moisture value corresponding to the Liquid Limit.
