North Carolina has an abundant supply of clean water, a resource vital to our high quality of life. Rivers, lakes, groundwater aquifers, and coastal estuaries are crucial to public health, economic development, and recreational opportunities. However, our water sources are constantly threatened with degradation by such activities as imprudent development, improperly managed agricultural and industrial activities, and unsound waste disposal practices. The soil exerts an important influence on water quality. How we manage the soil and what we put on it determine, in part, the level of treatment required to make our water supplies safe and enjoyable. This fact sheet explains how soils influence water quality and why efficient soil management helps protect 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.
Nearly all North Carolina soils are naturally acidic and need lime, which neutralizes the acidity, for optimum growth of crops, forages, turf, trees, and many ornamentals.

This publication discusses the effects of saltwater intrusion on soil fertility, how to identify issues with salt-affected soils, and various options to address these problems.
Sediment basins are temporary stormwater pools that catch runoff so it can deposit some of its sediment. The typical outlet is either a rock dam or a perforated riser barrel, both of which allow water to leave the basin from all depths. One way to improve the sediment capture rate is to use an outlet that dewaters the basin from the top of the water column where the water is cleanest. This publication describes the Faircloth skimmer, flashboard risers and other outlet configurations that accomplish this goal.
Selecting the right tool for a job is essential. When that tool is as important and expensive as a farm implement, the same holds true—you want to buy farm equipment that does what you want; is strong, durable, and reliable; and is generally the best value for your money.
This publication discusses the construction of fiber check dams on construction sites to control sediment and runoff from the site. To save money and reduce construction site impacts on nearby surface waters, how to install fiber check dams, spacing of the dams and maintenance of the dams are covered in this factsheet.
Phosphorus (P) is the second most important nutrient in crop production but is often found in relatively low amounts in native soils. Decades of fertilizer application have led to P enrichment of most North Carolina agricultural soils. Excess soil P that leaves agricultural fields via runoff and drainage can cause algal blooms in water resources that lead to impaired drinking water quality and can limit recreational activities. Maintaining adequate soil P levels for crop growth can reduce P runoff, save money, and protect the environment

The legal means for establishing sophisticated wastewater management programs have existed for some time in North Carolina; however, few communities or counties have used these programs to manage septic systems. Recent changes in state septic system rules will provide an incentive for communities to become involved in this process. This publication explains why these management programs are necessary and briefly introduces 12 options for implementing them.
Changes in the interpretation of North Carolina water quality rules and technical standards allow for the use of on-farm records in the development of waste management plans.
