Manure has often been referred to as a waste or an undesirable by-product of livestock and poultry production. In reality, manure is a valuable source of plant nutrients, soil amendment, and is fast becoming a popular renewable energy source. This page focuses on valuing manure for its nutrient content, calculating costs of manure storage and application operations, costs of odor control technologies, energy production costs and more.

Manure value calculators provide an estimated economic value based on the nitrogen, phosphorus, potassium and other nutrient content of the manure. Some of the newer web-based tools include "What is Manure Worth?" (University of Minnesota) and Oklahoma's poultry litter value calculator.
Two spreadsheets available for free download include the Nebraska Manure Value Calculator and Cornell's "Manure Cost, Value, and Time Management Calculator".
What does it cost to transport and apply manure? If a farm has too much manure to utilize on their own fields, what are some business arrangements to transfer manure off the farm? If you are looking at reducing air emissions from your feedlot, what are some of the costs to implement treatment technologies?
The most common system for utilizing manure as a renewable energy source is in the process of anaerobic digestion. Some additional uses are covered in "Manure Use for Fertilizer and Energy: June 2009 Report to Congress".

LPELC produced a webcast on developing apps for mobile devices that discussed the process of creating an app and provided an overview of several mobile manure apps.
