Nutrient Credit Trading (NCT) or
Water Quality Trading, which focus
greatly on phosphorus. NCT’s are
earned by the capture of nutrients
from non-point sources by virtue of
base conservation activities, such as
strip farming, no-till farming, and
contour farming. Capture techniques
such as these can be as efective in
nutrient planning, as recovery of
phosphorus from anaerobic diges-
tion liquid and manures. With proper
documentation, phosphorus removal
from AD eluent can qualify for
NCTs.
The recovery process
Some nutrient recovery techniques
manipulate pH levels in the water,
and require the addition of minerals
to optimize recovery from the solu-
tion. Phosphorus recovery is aided
by AD, as the process converts and
