“…Our mean K fs values ranged from 5.96 × 10 −7 to 1.45 × 10 −5 m s −1 (Table 4) and were generally higher than the range of conductivity or infiltration values (≤10 −9 m s −1 ) reported by others for feedlot pen surfaces (Mielke and Mazurak, 1976; Southcott and Lott, 1997; Kennedy et al, 1999; McCullough et al, 2001). Mielke and Mazurak (1976) reported infiltration rates of ≤10 −8 m s −1 using the double‐ring infiltrometer method, and Southcott and Lott (1997) reported mean infiltration rates (saturated coefficients of permeability) of 10 −8 m s −1 using the pressure infiltrometer method.…”

“…Studies of physical and chemical properties of feedlot pen soils with a focus on leaching have been conducted on single feedlots located on moderately coarse–textured (MC) (very fine sandy loam, fine sandy loam, sandy loam) and coarse‐textured (loamy sand, sand) soils (Campbell and Racz, 1975; Dantzman et al, 1983; Southcott and Lott, 1997; McCullough et al, 2001). Most of these studies reported little evidence for leaching below feedlot pens.…”

Physical and Chemical Properties of Feedlot Pen Surfaces Located on Moderately Coarse– and Moderately Fine–Textured Soils in Southern Alberta

Southern Alberta has the highest density of feedlot cattle in Canada, and there is a concern that leaching of water and contaminants may be greater for feedlots located on coarser-textured than finer-textured soils. Our objective was to determine if infiltration and leaching were greater for a 4-yr-old feedlot located on a moderately coarse-textured (MC) soil compared with two feedlots located on moderately fine-textured (MF) soils (5- and 52-yr-old pens). Various soil physical properties of feedlot pen surfaces were measured, including field-saturated hydraulic conductivity (K(fs)) and near-saturated hydraulic conductivity at -0.9 and -3.9 cm water potential. Selected chemical properties of feedlot soil layers were measured, as well as the chloride content of the soil profile (0-100 cm). Mean K(fs), K(-0.9), and K(-3.9) values were not significantly (P > 0.10) greater at the MC site than the two MF sites, indicating no evidence of greater infiltration on coarser-textured soils. In addition, mean K(fs), K(-0.9), and K(-3.9) values of soils within feedlot pens at all three sites were significantly (P < or = 0.10) reduced by 46 to 78% compared with soil outside the pens. Depth of chloride accumulation was greatest at the 52-yr-old feedlot on MF soil (60-70 cm), followed by 4-yr-old feedlot on MC soil (40-50 cm) and 5-yr-old feedlot on MF soil (30-40 cm). Visual inspection determined that the black interface layer formed within 2 mo of cattle stocking at all three sites.

“…Southcott and Lott (1996) reported a similar problem with very low infiltration rates, but found that hydraulic conductivities decreased from 3.1× 10 -5 cm/s before stocking to 2.3 ×10 -6 cm/s after six months in a clayey gravel soil and from 2.5 × 10 -4 to 1.4 × 10 -6 cm/s after six months in a feedlot in a silty sand soil. More recently, McCullough et al (2001) found conductivity went from 1.4E-5 cm/s to 1.2E-6 cm/s after 9-months use as a feedlot. These authors reported approximately an order of magnitude reduction in hydraulic conductivity, which is similar to the self-sealing effect often reported in earthen lined manure storages.…”

“…This is not to say leaching from a feedlot surface does not or cannot occur, but rather that on the timescale of the precipitation event seepage through this interfacial layer should be negligible in the overall water balance. For instance, Mielke and Mazurak (1976) reported feedlot infiltration rates of 0.12 cm/day while values from McCullough et al (2001) ranged from 0.05 to 0.16 cm/day. This is also true of concrete lots as no infiltration could occur; although in both cases significant fractions of precipitation could be stored in the accumulated manure depending on its moisture holding characteristics and its current moisture content.…”

A Runoff and Sediment Routing Model for Open Lot Beef Feeding Facilities

Feedlot runoff is a potential environmental contaminant and requires proper management to minimize impact on water quality. In designing runoff management systems, accurately assessing the amount of runoff that will be generated is of foremost importance. Along with overall quantity of runoff, the temporal pattern, both throughout the year and within an individual storm event, can have important implications for sizing control system components, in determining the performance the control system achieves, and in the overall pollution potential of the feedlot. This review summarizes the hydraulic properties of the feedlot surface, specifically focusing on variables that impact the total volume of effluent generated and the resulting amount of sediment transported. The work cumulates in development of a feedlot runoff routing model, presented as a series of equations that are implemented within the updated Iowa State University-Vegetative Treatment Area model, with a sediment transport/erosion component. Overall, the results indicated that a curve number of 91 was best for estimating runoff volumes, but substantial variation about this value could occur. The calibrated model was able to accurately estimate average total solids concentrations of lots of different size, shape, and surface condition under different hydraulic situations (R 2 = 0.92 for calibration and the slope of the measured vs. modeled data was not different than one during model validation). Most calibration and validation feedlots were earthen, had the majority of runoff from rainfall events, had mounds within the pen, and were scraped only once or twice per production cycle; thus model performance may be limited for other situations. The feedlot runoff and sediment routing components were used to assess the impact of various feedlot design characteristics, including feedlot area, aspect ratio, and slope, on solids transport from the feedlot surface. This model can be used to evaluate the risk that feedlot runoff poses to water quality for prioritizing feedlots that are in need of enhanced runoff control systems, and to evaluate the hydraulic and sediment loadings that a runoff control system is required to handle.
