Nutrient Management

Nutrient Management POLLUTANTS ADDRESSED: Nutrients and Organics i

DESCRIPTION: Managing nutrients involves the budget and supply of nutrients for plant production. By utilizing the amount, placement, and timing of plant nutrients, it leads to optimum crop yields.

POTENTIAL TREATMENT AREAS: Agricultural Lands

LOAD REDUCTION MECHANISM: Nutrients/Organics Management- Properly managing manure or organic by-products minimizes agricultural nonpoint source pollution of surface and ground water resources.

PERMITTING REQUIREMENTS: Application of manure requires a land application permit from ADEQ.

ALTERNATIVE MANAGEMENT MEASURES: Irrigation Water Management

LAND USE CLASSIFICATION: Cropland Management ADDITIONAL BENEFITS: Maintains or improves; physical, chemical, and biological condition of soil.

Management of nutrients leads to less runoff in streams, which feed algae and can lower oxygen.

PLANNING AND IMPLEMENTATION: 1. In areas with an identified or designated nutrient-related water quality impairment, an assessment should be completed of the potential for nitrogen and/or phosphorus transport from the field. The Leaching Index (LI) and/or Phosphorus Index (PI), or other recognized assessment tools, may be used to make these assessments. The results of these assessments and recommendations may be
