Simulating Crop Phenology by Gregory S. McMaster, from The Regional Institute, 4th International Crop  Science Congress, 2004. Simulating Crop Phenological Responses to Water by Gregory McMaster, John White, A. Weiss, P. Baenziger, Wallace Willhelm, J. Porter, P, Jamieson; USDA Agricultural Research Service; Jan. 2008.

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.

Land application of manure can be beneficial to crop production but can result in increased risk of P loss to surface waters. When manure is applied to meet crop nitrogen needs, the amount of P applied is typically much more than the P removed in the harvest of one crop. Effective January 1, 2007, operators of large CAFOs in Nebraska need to assess the risk of P delivery to surface waters from each of their designated fields by using a P index before manure can be applied.

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.

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.

20 kits of equipment and supplies for calibrating both dry and liquid manure spreaders are available in Extension offices across the state. Available for check-out for farmers and their advisors

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.

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

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.

The following are publications about manure and nutrient management.

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.

Custom Manure Applicators are becoming more commonly used by livestock producers in the state of Nebraska. While the regulations in Nebraska do not restrict the use of custom applicators or the methods that they employ, it is in their best interest to apply manure in accordance with the permit holder's nutrient management plan. It is, however, the responsibility of the permit holder (livestock producer) to make sure that happens.

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:

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.

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.
