Determining Crop Available Nutrients From Manure, Charles Shapiro, Leslie J. Johnson, Amy Schmidt, Richard Koelsch Jun 2021

Determining Crop Available Nutrients From Manure, Charles Shapiro, Leslie J. Johnson, Amy Schmidt, Richard Koelsch

Historical Materials from University of Nebraska-Lincoln Extension

This NebGuide discusses the availability and use of manure nutrients for field crop production. When managed correctly, nutrients in livestock manure can be a valuable resource. When managed improperly, however, these same nutrients represent a potential environmental pollutant. Accurate crediting of manure nutrients within a total crop nutrient program is fundamental to utilizing manure as a resource. This NebGuide illustrates how to estimate the crop available manure nutrients (part c, Figure 1) and calculate an agronomically based manure application rate. There are other tools available that do the calculations for you. This NebGuide will explain each step of the process ...

Good Riddance Rodents, Elizabeth Killinger

Historical Materials from University of Nebraska-Lincoln Extension

Holidays will be here soon and that means house guests might be coming. Take a few steps now to make sure your ‘guests’ are the ones you want at your house, not the furry, unwelcome kind. House mice are common guests once the outdoor temperatures drop. These small light gray, furry rodents have large ears and long tail. Their preferred food is grains, but they will munch on just about anything. One reason mice can be a problem once inside is due to their rapid ability to reproduce. Each year, a female mouse can produce 5-10 litters, with about 5-6 ...


Can Manure Management Be A Win-Win, Paul C. Hay Mar 2017

Can Manure Management Be A Win-Win, Paul C. Hay

Historical Materials from University of Nebraska-Lincoln Extension

Manure and Soil Health: What is the State of the Science? Can manure be both an economic ‘Win’ and an environmental ‘Win’? What fields provide the best opportunity for Win/Win? What exactly are the environmental and soil health wins associated with manure? Can we test soils so that we have more understanding of the value of manure nutrients and carbon? What are the biological processes in a soil system that benefit from organic fertilizers? These and other questions are the topics a new University of Nebraska working group addressing Manure and Soil Health (MaSH) plan to address. Rick Koelsch ...

Perennial Geraniums, Sarah Browning Jan 2015

Perennial Geraniums, Sarah Browning

Historical Materials from University of Nebraska-Lincoln Extension

Hardy geraniums are a great ground cover plant for sunny or partially shaded areas, but they are often confused with the beautiful annual geraniums found at the garden center in spring. Technically, annual geraniums are in the genus Pelargonium, while the hardy geraniums are true geraniums. However, hardy geraniums are great perennial plants that deserve to be used more in Nebraska gardens.


The Nebraska Phosphorus Index (2012): Background And Users Guide, Charles Wortmann, Charles Shapiro, Leslie J. Johnson, Renee F. Hancock Aug 2012

The Nebraska Phosphorus Index (2012): Background And Users Guide, Charles Wortmann, Charles Shapiro, Leslie J. Johnson, Renee F. Hancock

Historical Materials from University of Nebraska-Lincoln Extension

This publication provides the basis and procedure for using a phosphorus (P) index to assess risk of P delivery from agricultural land to surface waters. The P index is intended for planning as well as regulatory and educational purposes.

Phosphorus is an essential nutrient for the growth of both crops and aquatic vegetation. Phosphorus, either in inorganic form such as with fertilizer or in organic form as with animal manures, often needs to be applied to the land for optimal crop growth. An important byproduct of animal feeding is manure that contains P. Land application of manure can be beneficial ...


Manure Incorporation And Crop Residue Cover — Part I: Reduction Of Cover, David P. Shelton Jan 2012

Manure Incorporation And Crop Residue Cover — Part I: Reduction Of Cover, David P. Shelton

Historical Materials from University of Nebraska-Lincoln Extension

How residue cover is reduced by soil-engaging components typically used with tank spreaders and towed hose systems to apply liquid or slurry manure.

Manure incorporation represents a compromise between best management practices for soil erosion control and manure management. Manure should be incorporated into the soil for odor control, increased availability of nutrients, and control of potential manure runoff; however, disturbing the soil and crop residue may increase soil erosion and water runoff. This NebGuide summarizes the results of a field study to determine the influences on crop residue cover of common equipment used to simultaneously apply and incorporate manure.


G1564 Manure Incorporation And Crop Residue Cover — Part Ii: Fine-Tuning The System, David P. Shelton Jan 2012

G1564 Manure Incorporation And Crop Residue Cover — Part Ii: Fine-Tuning The System, David P. Shelton

Historical Materials from University of Nebraska-Lincoln Extension

How injector/applicator spacing, tire spacing, field speed, and other factors influence the amount of residue cover reduction after manure incorporation.

Manure incorporation represents a conflict between best management practices for soil erosion control and manure management. Manure should be incorporated into the soil for odor control, maximum availability of nutrients, and control of potential manure runoff. However, for maximum soil erosion control, the soil and crop residue should remain undisturbed. These two best management practices must be balanced since disturbing the soil and residue for manure incorporation, either with conventional tillage implements or equipment specifically designedfor manure application, reduces ...

Ec179 Managing Livestock Manure To Protect Environmental Quality, Michael A. Reynolds, Brian L. Benham, Richard B. Ferguson, Christopher G. Henry, Charles A. Shapiro, James P. Stack, Charles S. Wortman, Richard K. Koelsch

Historical Materials from University of Nebraska-Lincoln Extension

Proper utilization of livestock manure is a major environmental concern. Livestock manure has typically been considered a ‘waste product’ of livestock production. A more accurate name for this material is a ‘recycled resource’ from the production of livestock. By managing livestock manure, the producer has a second chance to utilize the nutrients that have already been paid for but not fully utilized by the animal. Collecting, containing, and properly spreading livestock manure will incur additional costs for the producer. However, these costs can be offset or justified by the producer in terms of the yield enhancement and nutrient credits that ...


Ballot Issues Education For The 2008 General Election, J. David Aiken, Bradley D. Lubben Jan 2008

Ballot Issues Education For The 2008 General Election, J. David Aiken, Bradley D. Lubben

Historical Materials from University of Nebraska-Lincoln Extension

Nebraska communities attempt to attract new employers to the community often by providing economic incentives to the new business: direct loans or grants, infrastructure improvements (roads, power, sewer lines, etc.), purchasing real estate, and job training grants. Communities can respond more quickly to new business development opportunities if the community has a pool of community development funds available for immediate use. The 1991 Nebraska Local Option Municipal Economic Development Act allows Nebraska cities and villages to create such a fund after preparing a community economic development plan, receiving voter approval and with continuing citizen review board oversight.1 Under current ...

Historical Materials from University of Nebraska-Lincoln Extension

On November 4, 2008, Nebraska voters will consider an amendment to the state constitution to ban many state or local government affirmative action programs (unless pending court challenges nullify the vote). The proposed constitutional amendment was brought forth by petition initiative and is modeled after similar language approved by voters in California (1996), Washington (1998), and Michigan (2006). Voters in Colorado will also face the same question this year on election day while similar efforts in Arizona, Missouri, and Oklahoma failed to reach the ballot.
