Nf05-632 Protecting Your Watershed, Thomas G. Franti, Steven R. Tonn Jan 2005

Nf05-632 Protecting Your Watershed, Thomas G. Franti, Steven R. Tonn

University of Nebraska-Lincoln Extension: Historical Materials

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 we do on the suface of our watershed impacts the water quality of our streams, wetlands, ponds, lakes and rivers. Like organs in a body, every part of the watershed is essential. What happens in one part affects other downstream parts. This NebFacts discusses the threat of pollutions in our watersheds, common runoff pollutants, and best management practices for protecting the watershed.

Ec04-704 Precision Agriculture: Listening To The Story Told By Yield Maps, Viacheslav I. Adamchuk, Achim Dobermann, Jianli Ping

University of Nebraska-Lincoln Extension: Historical Materials

When discussing current issues in precision agriculture, the terms “yield mapping” or “yield monitoring” often are used to refer to one of the most crucial components of the entire system for site-specific crop management. In fact, yield monitoring equipment was introduced in the early 1990s and is increasingly considered a conventional practice in modern agriculture. The pioneers of precision agriculture already have generated several years of yield history and have examined different ways of interpreting and processing these data. The goal of this publication is to review several common methods of yield data analysis and to discuss potential applications for …


G03-1504 Lime Use For Soil Acidity Management, Martha Mamo, Charles S. Wortmann, Charles A. Shapiro Jan 2003

G03-1504 Lime Use For Soil Acidity Management, Martha Mamo, Charles S. Wortmann, Charles A. Shapiro

University of Nebraska-Lincoln Extension: Historical Materials

Soil acidity can reduce crop production by directly affecting roots and changing the availability of essential nutrients and toxic elements. Liming can neutralize soil acidity, but several factors can affect the economic benefits of liming. With continuous cropping, soil pH can decrease (i.e., increase in acidity) because of various factors, including crop removal and leaching of basic cations, application of ammoniabased nitrogen fertilizers, and organic matter decomposition. Adding lime or other materials can raise soil pH to the ideal range for crop production, create an environment for a healthy function of microbes, and increase the levels of calcium or magnesium …

Ec02-178 Precision Agriculture: On-The-Go Vehicle-Based Soil Sensors, Viacheslav I. Adamchuk, Paul J. Jasa

University of Nebraska-Lincoln Extension: Historical Materials

Imagine that you are entering an unknown field and would like to estimate the productivity of the unfamiliar soil. You may pick up a handful of soil to evaluate its color and texture. You also can feel how difficult it is to break a clod apart, roll it into a ball or press out a ribbon. After repeating this procedure at different field locations, soil depths and times, you get a feeling of both spatial and temporal soil variability. Some of this variability can explain the non-uniformity of crop yield. If you collect soil samples and send them to a …

Ec02-153 Selecting Alfalfa Varieties For Nebraska 2002, Bruce Anderson, Michael Trammell, Charles A. Shapiro, Patrick E. Reece

University of Nebraska-Lincoln Extension: Historical Materials

Yield potential, pest resistance and seed price should be considered when selecting alfalfa varieties in Nebraska. The most important variety decision on many farms and ranches is the selection of alfalfa. The choice of alfalfa variety affects production for three to 10 or more years, whereas varieties of annual crops can be changed every year. Many alfalfa varieties are available from private and public plant breeders. Over the years, yield trials conducted at widely distributed Nebraska locations have tested most varieties sold in the state.

Ec01-157 Precision Agriculture: Untangling The Gps Data String, Viacheslav I. Adamchuk

University of Nebraska-Lincoln Extension: Historical Materials

Most people associate precision farming or site-specific management with the global positioning system (GPS). It is used to locate the antenna of aGPS receiver on Earth. GPS provides the opportunity to record a set of geographic coordinates that specify a particular field location. Therefore, field data collected using GPS technology is georeferenced. Processing of these data is complicated, and software packages designed for precision farming applications have built-in capabilities to interpret the GPS receiver output. However, some simple operations can be performed using standard office software. In this case, it is necessary to know the basics behind GPS data. The …


Ec00-1879 Sorghum Ergot In The Northern Great Plains, Jim Stack Jan 2000

Ec00-1879 Sorghum Ergot In The Northern Great Plains, Jim Stack

University of Nebraska-Lincoln Extension: Historical Materials

Sorghum is grown throughout Nebraska on approximately 0.6 million acres of land. It is grown as a forage crop as well as a grain crop. There is no significant commercial seed production in Nebraska. Grain sorghum is used domestically as livestock feed, in ethanol production, and to a limited extent as a food crop.

Grain sorghum is also exported to several countries. All sorghum hybrids (grain and forage) are susceptible to ergot disease. Ergot is a disease that impacts sorghum production directly by infecting unfertilized flowers and preventing seed development. Ergot also impacts sorghum production indirectly. Affected fields with honeydew-covered …

Ec00-154 Precision Agriculture: Soil Sampling For Precision Agriculture, Richard B. Ferguson, Gary W. Hergert Jan 2000

Ec00-154 Precision Agriculture: Soil Sampling For Precision Agriculture, Richard B. Ferguson, Gary W. Hergert

University of Nebraska-Lincoln Extension: Historical Materials

As various aspects of precision agriculture are implemented in Nebraska, some of the most frequent questions asked by producers, fertilizer dealers and crop consultants relate to soil sampling. Should I soil sample this field on a grid? What grid spacing should I use? How often should I sample? Can I use a yield map to tell where to soil sample? All of these are good questions, but often we do not have definitive answers. Site-specific management research conducted in recent years in Nebraska, however, provides some direction on how to implement a soil sampling program for precision agriculture.

Ec98-796 Farm*A*Syst Nebraska’S System For Assessing Water Contamination Worksheet 17: Stormwater Management At Residential Sites, Robert Grisso, Delynn Hay, Paul J. Jasa, Richard K. Koelsch, Sharon Skipton, Wayne Woldt

University of Nebraska-Lincoln Extension: Historical Materials

Stormwater is water from irrigation, rain or melting snow that does not soak into the ground. It flows from rooftops, over paved areas and bare soil, and across sloped lawns. As it flows, this runoff can collect and transport soil, pet waste, livestock manure, salt, pesticides, fertilizer, oil and grease, leaves, litter and other potential pollutants. A heavy rainstorm isn’t needed to send pollutants rushing toward streams, wetlands and lakes. A garden hose alone can supply enough water.

University of Nebraska-Lincoln Extension: Historical Materials

Waste is inevitable. Things which have been outgrown, broken, replaced, or are just no longer needed add to the waste produced at homes, acreages and around farms. Most of the waste accumulated around the farm, acreage and home is solid waste. Solid waste includes all discarded materials — newspapers, empty paint cans, liquids, gases, pickle jars, orange peelings, leftover food, worn out shoes, junk mail — this list is endless. Some of these solid wastes contain potentially hazardous materials.


Ec98-755 Farm*A*Syst Nebraska’S System For Assessing Water Contamination Risk Fact Sheet 13: Improving Milking Center Effluent Treatment, Robert Grisso, Delynn Hay, Paul J. Jasa, Richard K. Koelsch, Sharon Skipton, Wayne Woldt Jan 1998

Ec98-755 Farm*A*Syst Nebraska’S System For Assessing Water Contamination Risk Fact Sheet 13: Improving Milking Center Effluent Treatment, Robert Grisso, Delynn Hay, Paul J. Jasa, Richard K. Koelsch, Sharon Skipton, Wayne Woldt

University of Nebraska-Lincoln Extension: Historical Materials

Effluent from the dairy milking center, including discharges from the milking parlor (manure, feed solids, hoof dirt) and milkhouse (bulk tank and pipeline rinse water and detergent used in cleaning), is commonly disposed of in a variety of ways. Milking center effluent offers several unique challenges due to the presence of: 1. Large volumes of contaminated water which can overwhelm soil absorption systems. 2. Milk solids and fats and manure solids which plug many systems. 3. Cleaning sanitizers which reduce bacterial breakdown of solids. When these systems fail, effluent will become a risk to surface and groundwater quality.


Ec98-765 Farm*A*Syst Nebraska’S System For Assessing Water Contamination Fact Sheet 3: Improving Drinking Water Well Condition, Robert Grisso, Delynn Hay, Paul J. Jasa, Richard K. Koelsch, Sharon Skipton, Wayne Woldt Jan 1998

University of Nebraska-Lincoln Extension: Historical Materials

A properly installed and maintained system for treating and disposing of household wastewater will minimize the impact of that system on groundwater and surfacewater. State and local codes specify how wastewater systems must be designed, installed, and maintained. For example, Title 124 regulates the design, operation, and maintenance of septic tank systems in Nebraska. In addition, federal and state regulations guide the stabilization and land application of wastewater septage.
