liquidlimit: Soil Liquid Limit

Description

Function to determine the soil Liquid Limit by using the Sowers (1965) method. $$LL = \theta * (n / 25) ^ {0.12}$$.

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.
