“…To estimate the above base model, a mixedinteger linear programming model is formulated using General Algebraic Modeling System (GAMS). Previous studies (Bosch and Napit 1992, Fritsch and Collins 1993, Paudel et al 2002, Ribaudo et al 2003, Aillery et al 2009) have used linear and non-linear transportation models to address solutions for excess manure problems. None of these studies utilized a mixed-integer transportation model where non-agricultural land options of manure utilization are included.…”

“…Mathematical programming techniques have been widely used to determine the least-cost methods to utilize manure. Most of these studies have focused on minimizing transportation costs without considering processing options of manure (Bosch and Napit, 1991, 1992, Paudel et al 2002, Ribaudo et al 2003, Keplinger and Hauck 2006. While these studies utilized standards or guidelines for environmentally protective manure management, Ancev et al (2006) examined economically optimal strategies for manure management within a biophysical framework of pollution abatement within watersheds.…”

“…Our specific goal in this paper is to minimize the annual costs across society from the transport and/or processing of manure in order to eliminate county-level P excesses within agricultural land as a means of providing water quality protection from nutrient and manure management. This approach is typical of other existing research on the economics of manure management (Paudel et al 2002, Ribaudo et al 2003, Aillery et al 2009. A basic transportation problem approach is utilized where the cost of manure transported or processed is minimized by moving from surplus nodes (counties with excess manure P) to deficit nodes (counties with not enough P for agricultural land or counties with processing facilities).…”

A mixed-integer linear programming model was formulated to minimize the cost of transport and processing of excess manure in the Chesapeake Bay watershed. The results showed that primarily poultry manure was moved out of surplus counties for land application or processing. In the base model, annual cost was more than $350 million, with the bulk of the cost arising from construction of energy facilities for poultry manure. Forestland application of poultry manure had the lowest average cost, and more forestland than agricultural land was used for manure application. The lowest cost scenario was $127 million annually when constraints were removed to expand manure application on agricultural land and allow unlimited construction of composting facilities. Such a low-cost solution could not realistically be implemented without further development of markets for compost.

“…Most optimization studies focus on poultry litter relocation within a regional application. These studies model various aspects of integrated manuresheds, including relocation costs as a function of distance, watershed boundaries, nutrient application rules, the value of litter in sending regions, and the value of litter in receiving regions (Bosch & Napit, 1992; Catma & Collins, 2011; Govindasamy & Cochran, 1995; Jones & D'Souza, 2001; Paudel et al., 2003).…”

Stakeholders for nutrient‐impaired watersheds have long discussed the causes and consequences of nutrient surpluses associated with intensive livestock production. Nonetheless, nutrient surpluses relative to crop requirement, particularly with phosphorus (P), persist and continue to contribute to water quality impairment. Nutrient life‐cycle analysis shows that mineral P, from soil minerals or mined fertilizer P, flows to livestock regions from grain‐producing regions. Although creating a return flow of these nutrients to grain fields seems like an easy solution, significant economic obstacles exist to creating a connected manureshed over large geographic distances. To limit the impact of manure use on local surface water, state, federal, and nongovernmental actors have largely targeted their interventions in manure source areas. Even manure transport programs tend to focus on obstacles at the point of production in manure source areas. However, if we are to realize connected manuresheds that cost‐effectively distribute manure nutrients beyond the current publicly funded incentive programs, we must address obstacles to manure utilization in potential sink areas that supply grain to livestock regions. Further, we can harness the power of computer‐mediated market design and scientific research to build even more‐effective markets that generate manure nutrient transfers of an order of magnitude that will substantively improve water quality in source areas. This manuscript offers economic insights into potential improvements to current manure nutrient relocation programs. Under the right conditions, these improvements will relocate more manure, generate more environmental benefits, and improve the profitability of most participating farmers.
