When talking about the value of manure, costs are reported in terms of dollars. While reporting in terms of dollars is usually helpful, it is not the only metric for discussing costs. Any resource that is required to accomplish a task can be considered a cost. With this in mind, this page will discuss the cost of manure distribution in terms of dollars and time. The limiting resource, dollar cost or hours required, determines how manure is distributed. Hours could be converted to dollars but that would possibly obscure the management of these costs.
The three major activities that influence the cost of manure management are loading, transporting and land applying. Each activity can require its own specialized equipment and can constrain the use of the manure. For example, except for an external manure storage structure, loading is best done when animals are not present and thus limited to those time periods. Transportation can be time consuming depending on the distance traveled and the amount of water hauled in the manure. Land applying requires proper soil and plant conditions and specialized equipment.
Livestock manure is either liquid, slurry or solid. Different types of manure will have different impacts on the cost of distribution. For example, solid manure can usually be hauled farther for less money because less water is being transported. Liquid manure, because of its high water content, can’t be transported as far but low cost irrigation systems can be used to distribute it relatively inexpensively. This page will address each manure type separately. Because the dollar cost of managing manure is so dependent on location, type of livestock, form of manure, availability of land, etc. No dollar estimate will be given in this page. The quickest way to get a cost estimate would be to contact a custom manure hauler and ask the price charged for different services.
The table below summarizes the relative costs of manure application and distribution. When reading it, compare the costs within a column, rather than within a row. In other words, use it to compare the cost of loading, transportation, or land application for each type of manure. The more dollar signs ($) a manure type has, the more expensive it is relative to the other types of manure. Click on a type of manure in this table to be taken to a description of why different manures will have different costs.

Because much of the equipment used in manure application is unique to manure application, many livestock producers choose to not own the equipment but rather hire custom operators to handle their manure. Custom operators can lower the cost of manure management, relative to owner operated equipment, by spreading the cost of expensive equipment over more units. Many custom operators can also apply the manure more quickly due to experience and because they have larger equipment or multiple pieces of equipment. Because they work for many livestock producers, they may not be able to apply an individual’s manure at opportune times. This uncertainty of when the manure will be applied is a cost that needs to be taken into account. Contracting Certified Manure Haulers contains instructions for comparing custom hauling with producer hauling of manure.
Livestock manures are an excellent source of organic nutrients. However, they are generally more expensive to transport and land apply than more concentrated commercial fertilizers. The cost of manure transport and distribution are critical to understand and manage in order to derive maximum value from manure. A research project completed in the late 1990’s includes this information. The actual costs presented may no longer be relevant but the conclusions are still valid.
