PREVENT EXCESS FERTILIZER FROM BECOMING RUNOFF
Valley County soils contain plenty of phosphorus naturally. Excess“P” in fertilizer will run off your property and end up in lakes and streams, fueling algae and plant growth. Use organic fertilizer or chemical fertilizer with no phosphorus. The label has a nutrient ratio N-P-K. The middle number is “P” for phosphorus. Be sure the number is 0. Apply:
• Spring (after snowpack has melted) – May • Turf needs ½ to ¾ pounds of nitrogen for every 1,000 square feet. • Apply water to soak 6 to 8 inches into the ground.Watering Tip: If you see runoff or pooling water, turn water off and allow the soil to absorb the excess water.DEVELOPMENTS NOT FOLLOWING COUNTY STORMWATER POLLUTION PREVENTION PLAN (SWPPP) GUIDELINES
