Crop Planning - Manure Nutrient Analysis and Application

Default values for manure nutrient concentrations are typical values, but concentrations can vary substantially from these due to the feeding program, type of animal housing, and manure handling system. Additional variation occurs within animal feeding operations due to time of year and weather conditions.

Aquifers of Nebraska

There are at least seven major aquifer systems in Nebraska. By far, the High Plains/Ogallala aquifer is the largest in terms of volume of water in storage and withdrawals for irrigation. Several secondary aquifers exist in areas outside of the High Plains aquifer, providing water for irrigation, municipal supplies, and domestic use in parts of far western and far eastern Nebraska.

Septic systems operation and maintenance overview

Pump tank regularly. Have a professional inspect and pump the tank. Conserve water and spread usage over a period of time. Manage solids. Keep hazardous materials out. Let the system work naturally. Avoid drainfield compaction. Avoid introducing excess water to the drainfield. Maintain structural integrity of the drainfield.

NebGuides

A collection of NebGuides developed by Nebraska Extension professionals on various drinking water topics.

Small Farm Issues

Many of the manure management and environmental resources and publications are written for large livestock operations. Yet, most of the farming operations in the US are small. In Nebraska, for example, nearly 70% of all beef operations are less than 300 head and 90% are less than 1,000 head.

LID Atlas

The Low Impact Development (LID) Atlas was created for the National Nonpoint Education for Municipal Officials (NEMO) Network by the Connecticut NEMO Program and the California Center for Water and Land Use (http://lidmap.uconn.edu/). The LID Atlas is an interactive tool that provides examples of LID implementation throughout the country.

Pig Production Environmental Sustainability Footprints

A Nebraska Extension pilot project is assisting pork producers in calculating their swine farm environmental sustainability footprints in a joint effort with the University of Minnesota Extension.

What Happens in the Tank?

Anaerobic bacteria begin to break down some wastes in the tank. Wastewater contains suspended solids. Heavy solids settle out and form sludge on the bottom of the tank.

Drinking Water Testing

Testing private drinking water supplies in Nebraska is not required by federal or state regulation, with some exceptions such as licensed childcare facilities and foster care home water supplies. County or city jurisdictions may have requirements for private water supply testing.

Odor Footprint Tool

The Odor Footprint Tool (OFT) estimates the frequency of annoying odor events around an existing or proposed livestock facility and uses this information to determine minimum separation distances that should be maintained around those facilities and to help in siting decisions.

Permeable Pavers

Permeable pavers let water pass through the spaces between them which are often filled with small gravel or sand.

Wastewater - What Is It?

Wastewater comes from ordinary living processes: bathing, toilet flushing, laundry, dishwashing, etc. It comes from residential and domestic sources.

How does a septic system work?

A system typically has 3 parts: plumbing from the house, a septic tank, and an effluent treatment system.

Emergency Drinking Water Supply

Nebraska's abundant domestic water supply is generally taken for granted. However some situations can reduce the availability of safe drinking water, including tornadoes, floods, winter storms, or even earthquakes. Such disasters may interrupt the water supply for only a few hours or up to several days. In these situations an emergency water supply is helpful, if not essential.

Mortality Composting

Mortalities are an unfortunate reality for livestock operations. Whether they’re caused by disease or natural disaster, losses of livestock do occur and these mortalities must be managed responsibly. The state of Nebraska allows for disposal of dead animals via several methods including burial, rendering, incineration, composting, and landfilling.

Key Tips for Reducing Pollutants

Water pollution can come from a variety of sources. Soil, grass clippings, fertilizer, pesticides, paint thinners, and motor oil can pollute water if picked up by stormwater runoff.

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.

Understanding US EPA Regulations

Several federal regulations may impact animal producers and their operations including the Clean Water Act and provisions that relate to NPDES permits. The federal EPA statutes that have relevance to animal agriculture are summarized at EPA's Agricultural Law Web site.
