Design Tools for Small AFOs

This spreadsheet design tool is used to assist the Sprinkler Vegetative Treatment System  engineer in determining the flow rate, pipeline friction losses, elevation losses, pump capacity, and required horsepower for the pump station. This tool also evaluates the water flow characteristics in the towable sprinkler  system.  Here individual nozzle performance is evaluated along with tube friction loss and water velocity.

Odor Management

Odor emission is of great concern to the general public. An odor management plan is required in the permit application for livestock operations with more than 1,000 animal units. Producers need to understand odor emission from animal housing, manure storage and handling, and land application and available management options.

Estimating Manure N App Rates

Manure nitrogen application rates must be estimated annually 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 nitrogen application rates as part of a permit is, at best, an educated guess made without essential information. However, the underlying principles and assumptions that will be used to estimate manure nitrogen application rates can be defined in a permit application.

Manure Nutrient Losses

Manure nutrients are lost during manure handling, storage, treatment, and application. Manure nitrogen is especially vulnerable to volatilization when ammonium is transformed to ammonia. Losses of phosphorus and potassium are primarily due to runoff and erosion.

National SepticSmart Week is September 17-21

National Septic Smart week is Sept. 17–21, 2018. The U.S. Environmental Protection Agency (EPA) uses a week in September each year to focus on improved awareness of proper operation and maintenance of septic systems across the U.S.  The wastewater of approximately 25 percent of the population of the U.S. is treated by on-site or individual wastewater systems. In Nebraska, that statistic holds consistent with approximately 25 percent of our state’s population served by onsite wastewater systems on farms, acreages, suburbs and even some small communities.

Operation & Maintenance

Now that you know how a lagoon works, here is what you need to do to operate and maintain your system for maximum efficiency and long life. Minimize your exposure to wastewater - it contains disease-causing bacteria and viruses. Wear waterproof gloves, wash hands or shower, and disinfect breaks in skin after exposure to wastewater.

Reduce Need for Irrigation by Maintaining Crop Residue and Reducing Soil Tillage

Leaving higher levels of crop residue and doing less tillage can increase the soil water balance by increasing the amount of water that infiltrates the soil from irrigation or precipitation, and decreasing the amount of water that runs off the soil surface. More residue and less tillage also reduce the rate of evaporation of water from the soil. Maintaining residue on the soil surface and doing less tillage can significantly reduce the amount of irrigation water needed to grow a crop.

Nutrient Management

Water quality is affected by nutrient management when chemicals, soil, and residue move off of agricultural land or below it. This section focuses on a number of production issues that when managed correctly minimize the potential for off-site consequences because excess of the nutrients is limited or eliminated.

Pathogens and Organic Matter

Pathogens, typically microbes (e.g., bacteria, viruses, protozoa, fungi) or parasitic worms, are organisms capable of causing infection or disease in other organisms, including humans, wild and domestic animals, and plants. Several pathogens naturally occur in livestock and poultry manure and under certain circumstances may pose a risk to human health.

Groundwater Levels

Groundwater levels are an indication of how humans and climate have impacted the amount of water stored below ground, and the amount of groundwater that flows out of the ground to streams, rivers, springs, and lakes. Depletion of groundwater resources would have major social, economic, and ecological impacts in Nebraska and beyond.

How Does a Lagoon Work?

A traditional lagoon system is a two part system. A traditional system has plumbing from the house and a lagoon.

Why Manage Irrigation?

The goal of irrigation management is to use water in the most profitable way at sustainable production levels. For production agriculture this generally means supplementing precipitation with irrigation. In recent years we have seen declines in groundwater levels, almost statewide. Much of the State of Nebraska is considered fully or over-appropriated. This means that in those over-appropriated areas there will be no new development of irrigated acres.

Manure Value

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.

Papio-Missouri River NRD 2018 Groundwater Management Plan

The Papio-Missouri River Natural Resources District (P-MRNRD) 2018 Groundwater Management Plan incorporates and responds to new data and information about groundwater quantity and quality throughout the District.  The new plan incorporates data from studies, as well as regulation changes including:

What Happens in the Trench?

The effluent is distributed through the pipes/gravel or chambers, then percolates down into the soil. Oxygen is present and aerobic bacteria break down the waste. Viruses are held by soil particles and die over time.

Domestic Sewage FAQs

I have a septic system. What maintenance does it need? One of the most important things you can do to keep the system functioning properly is to have the septic tank pumped regularly by a certified professional. Scum and/or sludge could build up and be carried to the drainfield if the tank is not pumped regularly. This will clog the drainfield and not allow wastewater to be treated. Wastewater may form a pond in the yard or back up into the house. At that point you are probably facing costly repairs or replacement instead of minimal maintenance expenses.
