Focused Watershed Projects

Focused watershed projects bring together the combined resources and knowledge of many agencies and organizations to solve local watershed issues. Focused watershed projects that involve University of Nebraska–Lincoln Extension include the following. (By clicking on the linked titles you may go to the individual project Web site.)

Shoreline, Streambank & Lake Restoration

Shoreline and streambank protection is critical to maintaining water quality in streams, rivers and lakes. Degraded shorelines around lakes and along stream banks increase the likelihood of pollutants such as sediments and nutrients reaching the water and contributing to decreased water quality. Implementing best management practices in and around lakes and along streams can greatly reduce water quality problems.

Do I Need a Permit?

In Nebraska, an inspection by an NDEE representative will provide the final determination of whether or not a livestock or poultry operation will need a permit.

How and Why to Separate Turf from Ornamentals

Regardless of the mix, the goal for green minded gardeners is to grow, plant and care for healthy landscape plants and turf. One of the most important factors in the success of these endeavors is getting to know specific needs of the plant material and how they can be combined effectively in a landscape without compromising the needs of each component.

Graywater Use in Nebraska

With the forecast of another dry year, more people are inquiring about reusing their graywater to water their plants or lawn with. It is not legal in Nebraska to discharge untreated graywater. Wastewater in Nebraska is comprised of graywater and blackwater. Graywater is defined in Nebraska Onsite Wastewater Regulations as water that has been used for bathing, laundering clothes, and sink waste that is not kitchen sink waste. Blackwater is water that carries off waste from toilets, urinals, and kitchen sinks.

Chemical & Physical Characteristics of Pesticides

Understanding the chemical and physical characteristics of a pesticide allows the applicator to make better decisions about which pesticide active ingredient and/or formulation to use for a particular situation. Two chemical characteristics of interest are water solubility and volatility. The more water soluble a pesticide is, the greater the potential for runoff and leaching. The more volatile a pesticide is, the greater the potential for drift.

Publications on Watersheds & Watershed Management

Sediment, nutrient, and pesticide losses in runoff are major pollutants of surface waters in the Midwest. Targeting of Watershed Management Practices for Water Quality Protection addresses best management practices in watersheds or landscapes to maximize the impact of investments in water quality protection. This full-color, 23-page document is intended as a resource for those who advise on or practice land and water management.

Water Quality Protection Practices

Nonpoint source or runoff pollution is harmful to the water quality of our lakes, ponds, and streams. Many of our daily activities contribute to runoff pollution leaving our property and harming our lakes, ponds, and streams. Water quality protection practices help to reduce runoff pollution and protect our water resources.

Storage and Handling

Manure storage structures are key to managing manure from animal feeding operations. The three most popular containments used in Nebraska are categorized into: manure storages, anaerobic treatment lagoons, and runoff retention structures.

Nutritional Value for the Landscape

Processing lawn clippings and tree leaves into the lawn provides nutritional value as well as reduces waste. Generally, turf clippings contain 6-7% nitrogen, 0.5 to 1.0% phosphorous and 2-4% potassium; when returned to the lawn, they can account for a fourth of the lawn's fertilizer applications each year.

Irrigation Scheduling

G1579, Using Modified Atmometers (ETgage) for Irrigation Management Describes the atmometer (evapotranspiration gage) and explains how it can be used for irrigation scheduling. Examples are provided to show how information collected with an atmometer can be used to estimate crop water use for corn and soybean. PDF version (975 KB; 4 pages)

Regulations & Policies

Nebraska water resources play a major role in the state's heritage and economy. Beginning with the state constitution, Nebraska surface waters have been governed by the Appropriative First-in-Time, First-in-Right Rule which allows diversion of water from the surface waters of the state based upon the date the water right was obtained. Surface water rights entitle land owners or organizations to remove a set amount of water from a specific location.

Environmental Planning

Large animal feeding operations (AFO's) must follow regulations to protect water quality and preserve the environment. Smaller operations can help the environment as well. Livestock Producer Environmental Assistance Project (LPEAP) works with small farms to implement appropriate technologies and best management practices designed to protect water resources and our environment.

Demonstration Projects

Videos and resources on vegetative treatment areas, wetlands, low water stream crossings, and water quality projects.

Air Quality Issues

The federal Clean Air Act Amendment of 1990 (CAAA) has provisions of importance to producers of agricultural products. Although protecting air quality has inherent implications for livestock and poultry health as well as profitability, the language of air quality is derived principally from environmental regulations designed to protect public health and the use and enjoyment of private property.

CropWater App for Irrigation Management

The CropWater App is one of the earliest irrigation management apps developed many years ago and its functions are based on the research conducted by Dr. Suat Irmak. It is a product of our efforts in the NAWMN to enhance technology implementation in agricultural production.

Cover Crops

Crops including grasses, legumes or forbs used for seasonal cover and other conservation purposes. SARE Publications 2007, Managing Cover Crops Profitably, 3rd Edition. Beltsville, MD: Sustainable Agriculture Network, 244 pgs. $19 for book; PDF version available.

Economics & Costs

The University of Nebraska's Bureau of Business Research conducted a study in 2003 to determine the impact of irrigated agriculture on Nebraska 's economy. The net total economic impact was computed by comparing impacts with irrigation to what would have resulted without irrigation. The research examined actual 2003 impacts and what would have occurred if average precipitation had occurred. For normal precipitation the total impact of irrigation would have been just over $3.6 billion per year. Since 2003 was a drought year, the actual economic impact was more than $4.5 billion.

Estimating Manure P App Rates

Manure phosphorus application rates should be estimated. These estimates should be based upon the most recently available information for manure nutrient concentration (manure sample) and the estimate of crop nutrient needs. Since this information is not typically available at the time of a permit application, estimating manure phosphorus application rates as part of a permit is, at best, an educated guess made without essential information.

VTS Guidance Document

Vegetative Treatment Systems for Open Lot Runoff was developed under the leadership of U.S. Department of Agriculture (USDA) Natural Resources Conservation Service (NRCS) through an Intergovernmental Personnel Act (IPA) agreement, with collaboration from representatives from several land grant universities, USDA Agriculture Research Service (ARS), U.S. Environmental Protection Agency (EPA), Iowa Department of Natural Resources, Iowa Cattlemen’s Association, and private sector representatives.
