Nutrient cycling
N
NO3 dominates
denitrification suppressed (but not absent)
P
PO4 and TP dominates
regeneration of insoluble metaphosphates rare
suspended clays with + charge also adsorb P Þ Total P
on landscape P compounds generally less soluble
frequently limiting input to Photosyn, N:P ᡉ
exceptions in parts of the NW and SW, wetland rivers
