Manure Value and Economics

Poultry litter and beef feedlot manure are the most common types of “solid” manure. Separated solids from dairies can also be a source of solid manure. Solid manures must be scraped off the floor of the pen or house where the animals were raised. Scraping and loading onto trucks usually is done with a front end loader. If the manure is not land applied at the time the pens are cleaned, the manure can be stockpiled until needed. Poultry litter, in particular, when stockpiled is stored in covered sheds. The cost of the storage shed is an additional cost to manure loading.

Transport Costs of Solid Manure

As previously mentioned, solid manures are the least expensive to transport because most of the bulk transported is dry organic matter containing fertilizer nutrients (N, P and K). Water has little value in manure and adds a lot of weight that costs money to transport. Often, the manure is loaded into transport trucks that haul it to the receiving field, where it is unloaded and then loaded into an application truck.

Land application of solid manure.

Land Application of Solid Manure

Land application of dry manures is done with a flail type spreader. The manure, as it comes out of the truck-mounted or tractor-pulled spreader box, is flailed out in small pieces onto the surface of the soil. The spreader box is usually a specialized piece of equipment that can be expensive unless it is used to spread a lot of manure on many acres. If the manure needs to be incorporated into the soil, the cost of disking the manure into the soil could also be considered a cost of manure management.
