decomp: LINKAGES decomp function

In araiho/linkages_package: A Linked Forest Productivity - Soil Process Model

Description

DECOMP CALCULATES CARBON AND NITROGEN FLOWS THROUGH SOIL. AVAILABLE N (AVAILN) IS USED IN GMULT TO CALCULATE SOIL NITROGEN GROWTH MULTIPLIERS. AET IS FED IN FROM MOIST. THIS YEAR'S LEAF, TWIG, ROOT, AND WOOD LITTER IS FED IN FROM KILL (ARRAY TYL). THE SIMULATION STARTS ON BARE GROUND (ONLY HUMUS PRESENT. BASESC AND BASESN ARE STARTING HUMUS WEIGHT AND N CONTENTS READ IN INPUT). THREE TYPES OF SOIL ORGANIC MATTER ARE RECOGNIZED: COHORTS EITHER IMMOBILIZING OR RAPIDLY MINERALIZING NITROGEN AND A HOMOGENOUS HUMUS POOL SLOWLY MINERALIZING N.

Usage

decomp(fdat, aet, ncohrt, fc, dry, tyl, C.mat)

Arguments

fdat	current year
aet	average temperature by month for current year
ncohrt	average precipitation by month for current year
fc	field capacity
dry	wilting point
tyl	total yearly litter
C.mat	carbon matrix

Value

ff weights and n content of forest floor by litter type

availn available N

tyln leaf litter N content

hcn humus C:N ratio

sco2 total soil co2-c

ncohrt number of cohorts

C.mat matrix for data on litter cohorts
