Nebraska P-Index

(Revised December 2013)

Spreadsheet tool used for:

  • assessment of the risk of P loss from agricultural land to surface waters
  • land management planning
  • evaluation of management practices
  • education of factors contributing to P loss
  • regulation of P application to agricultural land

The 2012 P-Index version represents UNL Extension’s recommendation for assessment of risk of P runoff from agricultural land based upon the current state of the science. The 2012 P-Index is currently under review by the USDA Natural Resources Conservation Service and the Nebraska Department of Environmental Quality. Individuals using the 2012 P-Index should confer with NRCS and NDEQ as to its acceptability for planning processes managed by these organizations.

Beef Feed Nutrient Management Planning Economics (BFNMP$)

Beef Feed Nutrient Management Planning Economics (BFNMP$) is a comprehensive program connecting feed ration characteristics, manure storage type and cropping systems impacts on the value of manure as a fertilizer. This tool estimates:

  1. Manure mass and nutrient content
  2. Mass and nutrient losses during housing, storage, and land application
  3. Land requirements for agronomic utilization of the manure
  4. Labor and equipment time requirement and cost for manure handling and land application and travel distance of manure hauling
  5. Potential nutrient value of manure

Nebraska Manure Value Calculator

A simple calculator (*.xlsx) for the Value of Manure is available to correspond with the NebGuide: Calculating the Value of Manure for Crop Production, G-1519 (*.pdf)

See a tutorial to learn to learn how to use this tool.

(Under Title 130 transfers of manure"offsite" must be documented, however the "value" of the product does not.)

footprint imageOdor Footprint Tool

With the growing diversity of land uses in rural areas - agricultural, residential, recreational – it is important to have tools that can provide objective information about air quality issues associated with livestock production. 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. Another use of the tool is to compare odor control technology options for a facility. The separation distances take into account the size and type of facilities on the site, use of proven odor control technology, regional weather records, prevailing tolerance levels for odor, and local terrain.

Manure Management Planner

(Purdue University Web-tools)

Program developed at Purdue University for making nutrient management plans for crop and animal feeding operations. User enters information about the operation's fields, crops, storage, animals, and application equipment in order to allocate manure to fields for the duration of the plan (1-10 years).
Tool determines if the available land, manure storage facilities, and application equipment are sufficient for environmentally-sound manure use.
Windows-based software: Manure Management Planner Instructions are included at the Purdue Web site; but click here for additional help downloading and installing the software.

Additional tools available at the Purdue Web site:
Crop Nutrient Recommendations
Manure Nutrient Availability
For quick calculation of fertilizer requirements or manure nutrient availability, respectively.

Software can be downloaded from the Purdue MMP Website.

Whole Farm Nutrient Balance

Measuring tool can identify livestock and poultry operations that are accumulating or concentrating excess nutrients and evaluate the environmental benefit of alternative nutrient management strategies. Understanding the whole farm's nutrient balance and nutrient sources is critical to developing a nutrient management strategy. NM strategies can reduce imbalances and achieve environmentally sustainable operations.
(Not a required procedure under Title 130)

For additional information : Lesson 2 of LPES Curriculum

Nutrient Inventory

Tool estimates:

  • the amount of N, P, and feces excreted
  • the quantity of available nutrients after storage and land application losses
  • land requirement for utilizing remaining nutrients at an agronomic rate

Estimates of excretion are based upon a national ASABE standard released in 2005. Land requirement estimates are based upon the USDA NRCS Agricultural Waste Management Field Handbook, Chapter 11.

(Similar procedures are used by NDEQ to evaluate a permit application under Title 130).

Manure Use Plan

The Manure Utilization Planner is used to estimate the nutrient value of manure and credit those nutrients against the nutrient requirements of a crop. This information is combined with other fertilizer and nutrient credits for determining a nitrogen and phosphorus balance of individual fields. The Planner provides a summary action plan for the recommended manure and fertilizer application rates selected by the producer.

(This information can assist a producer in completing a Nutrient Management Plan which is required under Title 130.)

Other Software Packages

Calculate cost of spreading manure with the Distribution Cost Analyzer (U. of Missouri).

Apps for Manure Management

Manure Calculator

Manure Calculator has three sections. 1) calculate the amount of manure spread (calibrate your spreader) 2) calculate the amount of nutrients applied by using either your own manure test or using book values and 3) calculate the economic value of that manure. The app keeps a history of past entries and allows the user to email a single entry or an entire history to themselves for record keeping purposes. The value section was based on an existing spreadsheet from the University of Nebraska. The book values section was based on the ASABE 384.2 Manure Production and Characteristics standard.

The app can be accessed by searching for "Manure Calculator" in your app store or on iTunes or Google Play.

Manure Monitor is a utility that includes a farm emergency plan (for manure spills). The plan is updated by one person and everyone else can "sync" with that plan from their own devices. Other aspects of the app do not sync, but include carcass disposal, rainfall records, liquid manure storage levels, and others.
