Careful consideration should be given to further soil conservation and P management practices that do not increase P delivery to surface water. Water quality impairment will be large. Remedial action is required to reduce P movement to surface water bodies. P management practices are necessary to reduce offsite P movement and water quality degradation. Impacts on surface water resources are extreme.
Remedial action is required to reduce P delivery to surface water.
All necessary soil and water conservation practices plus a P management plan, which may require discontinuing P applications, must be put in place to reduce water quality impairment. See NRCS Nutrient Management Standard 590 for nutrient management recommendations.
