Implementation of BMP Santa Fe RFA Nitrate-N 2017-06 [Up]
On Page vii of 58:
"No significant decreases in nitrate-N concentration were observed over the four-
year period in the sampled springs or Santa Fe River sites.
This lack of response
may be related to
- (1) insufficient time for changes in agricultural practices to
affect groundwater quality
(a lag effect between when BMPs are implemented
and when improvements in water quality are seen);
- (2) legacy nitrogen in soil and
shallow groundwater from past practices;
possible compliance issues in the
implementation of BMPs
(although BMP compliance will be verified with
implementation assurance visits by the OAWP); and/or
the limitations of BMP
effectiveness because of soil conditions, cropping rates, fertilization rates, and
irrigation needs that may warrant additional measures
(if water quality problems
are observed despite BMP implementation).
Could it be (4)?
