Fertilizer Use

Fertilizer can cause problems for our groundwater.  These simple tips can help keep our water safe.

  • Avoid fertilizer use if periods of high rainfall are anticipated.  Precipitation can transport nutrients into groundwater and surface waters before they are absorbed by plants.
  • Use the appropriate quantity of fertilizer specified by the manufacturer.  Excess fertilizer is easily swept away by rain and wind.  Over application is costly and does not benefit plants.
  • Consider using compost or animal waste as a source of nutrients rather than inorganic fertilizers.  The high amounts of nitrogen and phosphorous in many fertilizers have the potential to negatively affect groundwater quality.
  • Plan your garden well.  Use plant species that are drought resistant and suited to local conditions.
