This factsheet describes the effect of fertilizer nitrogen on water quality and the environment. It provides guidelines for managing soil fertility on farms to preserve water quality.
This factsheet for farmers describes ways to control the harmful effects of excess nutrients while maintaining healthy, productive farm crops. Steps covered include testing your soil and following the soil testing recommendations, setting realistic yield goals, choosing the most suitable nitrogen sources, applying nitrogen correctly, using manure as a nutrient source, controlling erosion, managing water flow and fencing animals away from water flow.
This publication discusses best practices management to prevent agricultural activities from contaminating groundwater. It covers the role of soil on the quality of groundwater, soil characteristics, characteristics of potential pollutants and management practices such as nitrogen and pesticide management.
This publication discusses the results of recent nitrogen rate trials in the North Carolina coastal plain that assessed the recommendations of the Realistic Yield Expectation (RYE) database.
This publication discusses how the Nitrogen Loss Estimation Worksheet Tool can be used to account for agricultural nitrogen levels as an alternative to water quality monitoring.
This publication discusses the Realistic Yield Expectations database as a resource for nitrogen fertilization rate decisionmaking. Topics include recent research and the resulting updates to the database for improved nitrogen fertilizer rates based on new yield data.
