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

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)

Developed By State Team

UA. Div. of Ag
ADEQBased on
Runoff Plot Research
RUSLE
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.
Development and contents of a plan
Collecting information- on farm visit
Operation photo’s and maps
Soils and litter information / test results
RUSLE calculations
P-Index calculations
