Other Systems

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

Application Uniformity of In-Canopy Sprinklers, G1712PDF version Use of in-canopy sprinklers can reduce application uniformity and increase runoff. Learn how to evaluate the efficiency of in-canopy sprinklers.

Manure Nutrient Management

Water quality protection is primary to good stewardship of our environment; and fundamental to good stewardship is application of manure and fertilizer nutrients at field-specific agronomic rates with careful consideration of timing and location. Following nutrient management principles is a requirement for compliance with Nebraska and U.S. environmental regulations for all permitted animal feeding operations.

Stormwater Education for Kids

The stormwater activity sheets below can be downloaded and used with the Stormwater Sleuth comic book or on their own. They are designed for students from 4th - 6th grades, but may be appropriate for other ages as well.

Manure Value

Aerial view of evident manure application error

Manure is often an under-valued resource. When well-managed and properly applied, it reaps many benefits. The benefits can be seen in the photo to the left, but are not captured in much of the field because of errors in application.

Design & Size Requirements

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.

Precipitation Patterns

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.

Soil Erosion and Sediment Control

Soil erosion and sediment loss from construction sites has been documented as a major source of water pollution. Bare soil exposed to a rain event can become quickly eroded, leading to sediment that moves into adjacent storm sewers or lakes and streams.

Crop Planning - Soil Testing

Regularly checking soil nutrient status by sampling and analysis should be part of one’s crop production plans regardless of whether manure use is an option. However, soil testing is especially important with manure application to insure that excessive amounts of nutrients are not accumulating in the soil.

Groundwater Quality and Protection

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.

Troubleshooting Septic Systems

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

Furrow Irrigation

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.

Green Roofs

Green roofs help manage stormwater by capturing rainfall.

Stormwater runoff and your well

Protecting the quality and safety of your water supply means protecting your well and the area surrounding it by not storing hazardous materials including fuel, metals and chemicals near the well, keeping livestock including horses away, and limiting applications of lawn chemicals immediately around the well. However, to protect your water supply you need to look beyond the area immediately around your well.

Drainfield Size & Design

An important soil characteristic, the percolation rate, measures how long it takes water to drop one inch in a saturated hole dug in soil. Fast: 1 inch in 3 minutes (sandy soil). Slow: 1 inch in 48 minutes (clay soil). If it takes less than 5 minutes for the water to drop 1 inch in a saturated hole, the effluent will move too rapidly to be treated properly, such as in sandy soil.

Air Quality

The University of Nebraska is addressing air quality issues associated with animal agriculture in several ways because good air quality is very important to Nebraskans.

Low Impact Development

The key premise of low impact development (LID) is to allow natural systems to manage stormwater when and wherever possible. LID takes advantage of existing natural features and also designs and constructs systems to imitate natural processes, for example, green roofs, bioretention gardens, and permeable pavement.

Sandpit Lake Basics – What is happening in the water?

The last “Sandpit Lake Basics” article talked about some of the basic features of sandpit lakes from the water source to the physical features of sandpit lakes. This article will focus on what is happening in the water of a sandpit lake – something called the limnological characteristics.
