Calculate weighted average of soil column based on trapezoidal rule

Description

The purpose of this function is to calculate the weighted average of a soil property across a soil column over standard depth intervals. This function is designed to work on 4 depth breaks. This uses the trapezoidal rule as described in Hengl et al. (2017, https://doi.org/10.1371/journal.pone.0169748).

Usage

calc_soil_trapezoidal(
  depth1 = 0,
  depth2 = 5,
  depth3 = 15,
  depth4 = 30,
  value1,
  value2,
  value3,
  value4
)

Arguments

depth1	Numeric. Depth of top soil column interval. Defaults to 0 cm.
depth2	Numeric. Depth of second from top soil column interval. Defaults to 5 cm.
depth3	Numeric. Depth of third from top soil column interval. Defaults to 15 cm.
depth4	Numeric. Depth of bottom soil column interval. Defaults to 30 cm.
value1	Numeric. Value of the soil property at depth1.
value2	Numeric. Value of the soil property at depth2.
value3	Numeric. Value of the soil property at depth3.
value4	Numeric. Value of the soil property at depth4.

Value

Numeric. Weighted mean of soil values.
