Description

Parameter estimation based on class of Staringreeks (Tabel 3, Wosten 2001)

Usage

pFpara_class(Pklei, Pleem, Psom, M50)

Arguments

Pklei

(numeric) The clay (<2um) content of the soil (%)

Pleem

(numeric) The loam (<50um) content of the soil (%) Pleem > 0

Psom

(numeric) The organic matter content of the soil (%) Psom > 0

M50

(numeric)size of sand fraction (um)

Value

a table with the following columns: ThetaR (numeric) residual water content (cm3/cm3) ThetaS (numeric) saturated water content (cm3/cm3) alfa (numeric) related to the inverse of the air entry suction, alfa > 0 (1/cm) n (numeric) a measure of the pore-size distribution, n>1, dimensionless ksat (numeric) saturated hydraulic conductivity (cm/d)

Examples
