Transcript of Water Quality Nutrient runoff – the primary concern is with Phosphorous.

Water Quality

Nutrient runoff – the primary concern is with Phosphorous

Pros

Essential element for plant and animal life

Not considered a human health issue

Cons

Can accumulate in and degrade the quality of freshwater streams and lakes- Eutrophication

Accelerated aging

Excessive plant growth

P usually limiting factor

Accelerated aging

Excessive plant growth

P usually limiting factor

Results

“off flavor” drinking water

Lower oxygen levels

Reduction in aquatic populations

Commercial fertilizer- can be mixed to any ratio; but can be expensive.

Poultry Litter – excellent sources of the essential Nutrients and provides an organic material that acts as a soil amendment; but can not be used if soil test phosphorous is high.

Requiring Nutrient Management Plans

Requiring qualified personal to apply Nutrients

Development of a protective rate of application

Identifying areas of concern

Development of a Phosphorous Index (P-Index)

Soil Characteristics

Historical runoff information

Professional judgment

(P Index = Source x Transport x Precipitation x BMP)

Evaluates P runoff risk

Greater values = greater risk

Establishes risk ranges

Permits “what if” Planning

provides management options

Makes planning a decision making process

Lets landowner adjust management.
