Soil Biological Life

While tillage has been used to prepare a seedbed, it also destroys the existing root structures in the soil and some of the soil's biological life. Without this biological life, soil structure suffers and many of the nutrients are not as available for crop uptake.

Project Background

The Nebraska Ag Water Management Network (NAWMN, Irmak (2005)) project is designed for encouraging the adoption of newer technologies that will enable farmers to use water and energy resources associated with irrigated crop production efficiently.

Professional trainings and public programs

UNL Extension presents trainings for water well professionals as part of their CEU requirements. UNL Extension also conduces educational sessions at professional conferences and seminars. Extension also educates both urban and rural residents to increase understanding of good management of drinking water supplies. Nitrate, arsenic and uranium are identified as some of the top concerns for water supplies. These issues and more are the subjects of UNL Extension's educational efforts.

LB 677 and Its Impact on Nebraska Animal Feeding Operations

U.S. Environmental Protection Agency (EPA) rules that took effect April 14, 2003 defined the procedures for defining animal feeding operations (AFOs) as well as concentrated animal feeding operations (CAFOs). CAFOs are required to obtain a National Pollutant Discharge Elimination System (NPDES) permit from Nebraska Department of Environment Quality.

Landscape Design Practices

Install rain gardens in locations where they catch and temporarily hold rainwater. Use natural drainage patterns, site grading, berms (planted earth mounds) or other methods to channel rainwater away from impervious surfaces (i.e. pavement) onto planted areas such as grass swales, filter strips, or rain gardens. Plant and maintain healthy plant cover, especially on slopes to stabilize the soil and prevent erosion. Select plants adapted to the site and maintenance level.

Introduction to Watersheds

Everyone lives in a watershed. A watershed is the land area that contributes water to a location, usually a stream, pond, lake or river. Everything that we do on the surface of our watershed impacts the water quality of our streams, wetlands, ponds, lakes and rivers. What happens in one locality affects other downstream areas.

Frequently Asked Questions

What is Algae? Algae are defined as simple rootless plants that grow in bodies of water relative to the amount of nutrients available. Blue-Green Algae or Cyanobacteria:

Am I Current with Inspections & Records?

Documentation is critical to demonstration of a CAFO's compliance with regulations and good environmental stewardship. Records are especially important if a farm experiences a spill. A farm's ability to demonstrate continued good management prior to a spill will be an important consideration in determining liability and potential penalties.

Publications and Resources

Nebraska Extension Educators and Specialists have developed many resources to help you use water more efficiently and help keep it clean. Nebraska Extension has also developed materials to help youth learn about water and how to save it and keep it clean. Read on for a listing of all of these great resources for your landscape

Pesticide Leaching & Runoff Management

Runoff and/or leaching can occur when pesticides are carried off the application site into water such as rivers, lakes and streams, wells, storm sewers, or into groundwater. Runoff/leaching can occur when too much pesticide is applied or is spilled on the surface, too much rainwater or irrigation water occurs in a short period of time, or highly water soluble pesticides are used. To gain a better understanding of how, where and why water runs off and how to prevent pollution read the following UNL publications:

Watershed Planning & Management

Watershed planning and management comprise an approach to protecting water quality and quantity that focuses on the whole watershed. This approach is necessary due to the nature of polluted runoff, which in most watersheds is the biggest contributor to water pollution. Polluted runoff is a caused by a variety of land use activities including development, transportation and agriculture, and may originate anywhere in the watershed. Watershed planning and management involves a number of activities including:

Pond Management Tool

A pond is a delicate aquatic ecosystem where multiple interactions affect one another. Knowing the surface area and volume of a pond is critical information to making proper pond management decisions about chemical dose, evaporation/filling rates, fish stocking rates, etc. Inaccurate measurements of area or volume can lead to ineffective aquatic plant management via under dosing, or worse, overdosing. Overdosing can remove too much plant biomass causing oxygen depletion and can potentially lead to fish kills.

Methane (Anaerobic) Digesters

A methane digester system, commonly referred to as an AD (anaerobic digester), is a device that promotes the decomposition of manure or 'digestion' of the organics in manure to simple organics and gaseous biogas products.

Water Zones

Once good soils are in place, create water zones. Water zones are distinct sections of your property which contain plants with similar water needs. Group ornamentals into H-M-L zones in the landscape. Keep each distinct plant group by themselves – set watering minutes per zone accordingly.

What is a pesticide?

The public is becoming increasingly concerned about the harmful effects of pesticides on the environment. Protecting water and the environment is a key element of the University of Nebraska-Lincoln Extension Pesticide Safety Education Program (PSEP). It is essential that pesticide applicators understand all aspects of the pesticides they use in order to properly manage them. Whether you want to learn more about protecting human health, the environment, becoming certified and licensed, or improving your bottom line UNL Extension PSEP can help!

Subsurface Drip

Advantages and Disadvantages of Subsurface Drip Irrigation, EC776 (PDF, 1.2 MB; 8 full color pages) Discusses subsurface drip irrigation, including the advantages of water application efficiency and savings, energy savings and potential yield increases and the disadvantges of initial investment, system capacity, design restrictions and emitter clogging.

Livestock & Poultry Expansion: Critical Issues for Discussion with Farmers and Communities

There is a growing interest in establishing new livestock and poultry facilities in Nebraska, many of which will involve contractual arrangement with supply chain partners. Our purpose is to inform Extension educators and other farm advisors on those critical issues to be considered in the planning of a new livestock/poultry facility and prepare these advisors for leading farmers successfully through this process.

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.
