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.

Some areas in Nebraska are not appropriate for a conventional septic tank/drainfield system or a residential lagoon. We consider these environmentally vulnerable areas.

Manure contains four primary contaminants that impact water quality: nitrogen, phosphorus, bacteria and other pathogens, and organic matter.

Lagoon size is determined by the number of bedrooms, as well as the annual evaporation and precipitation rates for the geographic region. The lagoon size is NOT based on the square footage of the house, or the number of people living in the house because occupancy can change.

Another major factor in irrigation scheduling is making use of precipitation, both during the growing season and in the off season. Shown below is a map detailing the average net irrigation requirement for corn for the State of Nebraska. The net irrigation requirement is based on precipitation patterns and soils. In wet years less water is needed and in dry years more water will be needed.

The National Pollution Discharge Elimination System (NPDES), established through the Federal Water Pollution Control Act (FWPCA) Amendments of 1972 (later amended and known collectively as the Clean Water Act), regulates water quality by requiring a permit for point source pollution discharges to waters of the United States.

An annual crop nutrient management plan is needed to ensure an adequate supply of nutrients to sustain profitable crop production, and to balance nutrient inputs (including manure) with crop nutrient needs. Title 130 of the NDEQ requires that a permit application include a nutrient management plan with manure sampling and analysis procedures, soil sampling and analysis procedures, and planned land application rates, methods, and frequencies.

In many parts of Nebraska, the natural quality of groundwater is suitable for both humans and ecosystems. However, in some areas the groundwater quality has been impacted by high levels of nitrate from human activities, or naturally high levels of uranium or arsenic. These groundwater quality issues can cause significant challenges for communities, in part because of the cost of treating groundwater to reduce contaminants to meet drinking water standards.

Problems sometimes occur. Some of the problems that occur include: sluggish drainage, contaminated drinking water, wastewater surfacing in the yard, odors, and pipes freezing.

Advantages to furrow irrigation include lower initial investment of equipment and lower pumping costs per acre-inch of water pumped. Disadvantages include greater labor costs and lower application efficiency compared to sprinkler and subsurface drip irrigation. The number of furrow irrigated acres in Nebraska has decreased from 2.4 million to approximately 1.5 million acres in the past 10 years.

Livestock Waste Regulations in Nebraska are enforced by the Nebraska Department of Environmental Quality NDEQ). NDEQ administers both state and federal (EPA) environmental regulations. The governing regulations are called Title 130, Livestock Waste Control Regulations.
