Usage

Tamminen_1993_SI_prediction_southern_Finland_Norway_Spruce(
  vegetation,
  temperature_sum,
  fine_fraction_lower_than_15_percent = FALSE,
  clay_content_higher_than_10_percent = FALSE

Tamminen_1993_SI_prediction_southern_Finland_Scots_Pine(
  vegetation,
  temperature_sum,
  humus_thickness_cm,
  rod_penetration_cm,

)

Arguments

vegetation	One of "OMT"<"MT"<"VT"<"CT". For Spruce one of: ("LH" equal growth as "OMT")<"MT"<"VT"
temperature_sum	Effective temperature sum (>5 C), e.g. Ojansuu & Henttonen 1983.
fine_fraction_lower_than_15_percent	Boolean. TRUE if fine fraction of soil is lower than than 15 percent, otherwise FALSE (default)
clay_content_higher_than_10_percent	Boolean. TRUE if clay content of soil is higher than 10 percent, otherwise FALSE (default)
humus_thickness_cm	Thickness of humus layer, in cm.
rod_penetration_cm	Penetration of stone rod, e.g. Viro 1952.
shallow_soil	Boolean. TRUE if shallow soil (<30 cm to bedrock) else FALSE (Default).
