Research has shown several important benefits of planting winter annual cover crops, chief among them erosion control, addition of nitrogen (N) to the soil for use by a subsequent crop, removal of nitrogen from the soil to prevent nutrient loading, buildup of soil organic matter and buildup of residue that acts as a mulch for water conservation or retention.
Runoff on construction sites often contains large amount of soil and trapping it before it leaves the site is critical in preventing damage to streams, rivers and lakes. This factsheet describes sediment traps and basins at construction sites and agricultural operations, which provide temporary pools for runoff that allow sediment to settle before the water is discharged into water.
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 the features of coastal dunes and construction of new dunes using vegetation. The procedures recommended can help restore, enhance, and protect dune vegetation.
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 publication offers a discussion on how to lime Fraser fir Christmas trees. Fraser fir Christmas trees require a lower soil pH than most crops grown in North Carolina. Special management strategies for soil pH, calcium, and magnesium are needed to provide proper nutrition without over-liming.
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
Nitrogen fertilizer products are being developed and marketed as having the potential to increase yields and nutrient use efficiency, and decrease volatilization (gas). How do these products actually perform on different soils and row crops, under various climatic conditions? This publication summarizes findings from recent studies that investigated alternative nitrogen fertilizer products for row crops in four North Carolina regions.
Phosphorus management is an important aspect of the USDA-NCRS nutrient management standard.

This factsheet describes the nutrient composition of poultry manure and land application techniques based on matching the nutritional requirements of the crop with the nutrients available in manure. This publication also includes a worksheet to determine the nutrient needs of your crop.
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.
