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

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

Historical Materials from University of Nebraska-Lincoln Extension

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

Historical Materials from University of Nebraska-Lincoln Extension

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

Historical Materials from University of Nebraska-Lincoln Extension

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 ...

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

Historical Materials from University of Nebraska-Lincoln Extension

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

Historical Materials from University of Nebraska-Lincoln Extension

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

Historical Materials from University of Nebraska-Lincoln Extension

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 ...

Ec00-154 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

Historical Materials from University of Nebraska-Lincoln Extension

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.

G96-1362 Soil Temperatures And Spring Planting Dates, Steven J. Meyer, Allen L. Dutcher

Historical Materials from University of Nebraska-Lincoln Extension

Dates on which soil temperatures reach a threshold value are presented as a spring planting guide for agronomic and horticultural producers.

For a seed to germinate it must have good contact with the soil and be placed in a favorable soil environment. A good soil environment is one that has suitable soil temperature, adequate soil moisture, good aeration, and for certain seeds, light. Conditions necessary for germination depend on the species and variety of seed being planted. Alone, none of these factors guarantee germination; rather it is the interaction of these factors that affects seed germination.

In Nebraska, soil moisture ...

To solve shade garden problems, shade's positive and negative aspects need to be considered.


G98-1372 Management Recommendations For Blocked-End Furrow Irrigation, Dean E. Eisenhauer, Brian L. Benham Jan 1998

G98-1372 Management Recommendations For Blocked-End Furrow Irrigation, Dean E. Eisenhauer, Brian L. Benham

Historical Materials from University of Nebraska-Lincoln Extension

Proper blocked-end furrow irrigation management practices can minimize water application, irrigation costs and the leaching of agri-chemicals below the root zone.

The goal of every irrigator should be to apply the right amount of water uniformly to meet crop needs. To do this, irrigators need to know how much water is applied and where it goes. In other words, they need to know how uniformly the irrigation water infiltrates into the soil profile. Achieving a uniform water application is not easy when using furrow irrigation. However, with a better understanding of how irrigation system management affects water distribution and a ...
