“…In 2013, 42 drinking water associated outbreaks occurred in the US resulting in 1,006 cases of illness and 13 deaths primarily due to Legionella, Cryptosporidium, and Giardia (Braeye et al, 2015). Poultry farms in particular have been shown to cause increases in copper, zinc, potassium, and other nutrients concentrations into nearby rivers due to runoff of poultry litter (DeLaune and Moore, 2016;Sharpley et al, 2018).…”

Nutrient and pathogen pollution are the leading causes of water quality impairment in lakes, reservoirs, and rivers in the United States. Dissemination of these contaminants can result in eutrophication of freshwater resources and pose a risk to public health through recreational contact and degradation of waters used as drinking water sources. Agricultural production practices, both crop and animal, have been identified as sources of excess nutrients and microbial pathogens contributing to freshwater pollution. In the U.S., commercial meat poultry production has been targeted as a source of both excess nutrients, especially phosphorus, and fecal indicator bacteria (FIB) in regional watersheds. Recently, there has been an increase in pastured poultry operations where chickens have access to fresh pasture on a daily basis. However, few studies have explored the environmental sustainability of these types of poultry production systems. In the case of pastured poultry systems in close proximity to watersheds, there is a need to better understand potential environmental impacts in order to implement sustainable and cost-effective practices. The identification of such environmental and economic benefits would complement the mission and objectives of farmers using pastured poultry production systems and may add more value to their product. This review will focus on potential mitigation strategies to enhance environmental sustainability and provide economic benefit to small scale pastured poultry operations.

“…Large storms often occurred shortly after poultry litter application in those studies, thus representing the worse‐case scenario for nutrients and metals in runoff. DeLaune and Moore (2016) also reported high Cu concentrations in runoff water from pastures that received poultry litter as fertilizer source.…”

Metal runoff from fields fertilized with poultry litter may pose a threat to aquatic systems. Buffer strips located adjacent to fields may reduce nutrients and solids in runoff. However, scant information exists on the long-term effects of buffer strips combined with grazing management on metal runoff from pastures. The objective of this study was to assess the 12-yr impact of grazing management and buffer strips on metal runoff from pastures receiving poultry litter. The research was conducted using 15 watersheds (25 m wide and 57 m long) with five treatments: hayed (H), continuously grazed (CG), rotationally grazed (R), rotationally grazed with a buffer strip (RB), and rotationally grazed with a fenced riparian buffer strip (RBR). Poultry litter was applied annually in spring at 5.6 Mg ha. Runoff samples were collected after every rainfall event. Aluminum (Al) and iron (Fe) concentrations were strongly and positively correlated with total suspended solids, indicating soil erosion was the primary source. Soluble Al and Fe were not related to total Al and Fe. However, there was a strong positive correlation between soluble and total copper (Cu) concentrations. The majority of total Cu and zinc was in water-soluble form. The CG treatment had the highest metal concentrations and loads of all treatments. The RBR and H treatments resulted in lower concentrations of total Al, Cu, Fe, potassium, manganese, and total organic carbon in the runoff. Rotational grazing with a fenced riparian buffer and converting pastures to hayfields appear to be effective management systems for decreasing concentrations and loads of metals in surface runoff from pastures fertilized with poultry litter.

“…This is because watershed models lack the routines to simulate fate and transport processes of metals. DeLaune and Moore (2016) conducted a runoff study on fescue pasture and compared the concentration of Zn and Cu in surface runoff among different treatments (e.g., plots fertilized with alum‐treated litter, fresh litter). In our study, the concentrations of Zn and Cu in surface runoff from plots with surface‐applied broiler litter were within the range of Zn and Cu concentrations in surface runoff reported by DeLaune and Moore (2016).…”

“…Moore et al (1998) reported that treatment of broiler litter with aluminum sulfate can reduce concentrations of Zn, Fe, Cu, and As in surface runoff. DeLaune and Moore (2016) reported that composting poultry litter decreased soluble Cu concentration in surface runoff. Furthermore, broiler litter application rate and timing to tall fescue ( Festuca arundinacea Schreb.)…”
