“…The filter strip trapping efficiency for sediment, nutrients, and pesticides and the reduction of nutrient loadings transported in surface runoff due to the filter strip are calculated as trap = 0.367(FILTERW) 0.2967 (Neitsch et al 2004). Trapping efficiency in the form of an exponential equation indicates greater pollutant reduction in the leading edge of the filter strips, similar to the filter strip efficiency measured in pasture areas (Chaubey et al 1995;Srivastava et al 1996).…”

Abstract:The nonpoint source pollution problem can be controlled by implementing various best management practices (BMPs) in the watershed. However, before such practices are adopted, their effectiveness at various spatial and temporal scales must be evaluated. The objective of this research was to evaluate a suite of BMPs in a pasture-dominated watershed in their effectiveness at controlling nutrient losses. A total of 171 different BMP combinations incorporating grazing and pasture management, riparian and buffer zones, and poultry litter applications were evaluated for their effectiveness using the Soil and Water Assessment Tool (SWAT) model. The SWAT model was parameterized using detailed farm and watershed-scale data. The stochasticity in weather was captured by generating 250 various possible weather realizations for a 25-year period, using measured historical climate data for the watershed. Model results indicated that losses of both total nitrogen, mineral phosphorus, and total phosphorus increased with an increase in litter application rates. For the same application rates, greatest losses were predicted for fall application timings compared to spring and summer applications. Overgrazing resulted in greater nutrient losses compared to baseline conditions for all application rates, timings, and litter characteristics, indicating that overgrazing of pasture areas must be avoided if any improvement in the water quality is to be expected. Variability in weather conditions significantly affected BMP performance; under certain weather conditions, an increase in pollutant losses can be greater than reductions due to BMPs implemented in the watershed. Buffer strips and grazing management were two most important BMPs affecting the losses of total nitrogen and total phosphorus from the pasture areas.

“…The SWAT model predicted that 30 m buffers would reduce TP losses by 66% from the watershed. Chaubey et al (1995), based on simulated rainfall studies in Arkansas, have reported that 21 m (69 ft) buffer strips reduced TP losses by 92%.…”

“…The effectiveness of VFS is influenced by runoff rate, length of the vegetative filter, and characteristics of the runoff area (Bingham et al, 1980;Daniels and Gilliam, 1996;and Robinson et al, 1996). Chaubey et al (1995), Srivastava et al (1996), and Lim et al (1998) examined the effects of VFS length on the concentrations and transport of nutrients in runoff from fescue plots treated with manure. The VFS significantly reduced discharge concentrations of incoming constituents.…”

Abstract. The use of setback distances for manure application on cropland areas adjacent to surface water bodies could serve a function similar to vegetative filter strips. However, little information currently exists to identify the setback distances necessary to effectively reduce the transport of contaminants in runoff. The objective of this study was to determine the effects of setback distance and runoff rate on concentrations of selected constituents in runoff following land application of swine slurry to a no-till cropland area in southeast Nebraska. The study site had a residue cover of 7.73 Mg ha-1 and a slope gradient of 4.9%. The twenty plots examined during the investigation were 3.7 m across the slope by 4.9, 7.9, 11.0, 17.1, or 23.2 m long. An initial set of rainfall simulation tests were completed to identify background concentrations of selected constituents. Swine slurry was then applied to the upper 4.9 m of each plot, and additional rainfall simulation tests were conducted on the same plots examined previously. A first-order exponential decay function was used to estimate the effects of setback distance on concentrations of selected constituents. A setback distance of 12.2 m reduced runoff concentrations of dissolved phosphorus (DP), NH4-N, total nitrogen (TN), boron, chloride, manganese, potassium, sulfate, zinc, electrical conductivity (EC), and pH to background values similar to those measured for the no-slurry condition. Runoff rate significantly influenced transport of several of the constituents, with concentrations generally decreasing as runoff rate increased. The transport of selected pollutants in runoff was significantly reduced when setback areas were employed.

“…Hence, it might have promising implications for sustainability to assess the impact of animal husbandry on the environment and biogas energy potential stemming from the excreta in rural areas. Several studies provided evidences of the management effectiveness in reducing sediments and nutrients contained in runoff (Chaubey et al, 1995;Rodriguez et al, 2011). However, the general substantial explorations and effective options are not as put forward as could be in developing countries, including China, although recently case study progress has emerged in controlling water pollution or promoting biogas, especially in some nutrient-surplus areas around the world (Ding et al, 2012;Dai et al, 2015).…”

a b s t r a c tGlobal livestock and poultry industry is growing continuously, with large amounts of excreta produced. These wastes could be either important anaerobic fermentation materials of biogas energy or, if discharged into the environment without appropriate processing, serious pollution sources to soil and water systems. In developing countries, rural energy poverty is currently a major threat to sustainable development and livelihoods. Hence, the availability of clean, affordable and reliable energy is of significant concern in both policy and scholarly circles. Moreover, pollutants related with animal husbandry have been identified as one of the dominant contributors to contamination of water systems, such as surface water eutrophication and groundwater nitrate enrichment. Consequently, assessing waste from livestock and poultry breeding and the associated biogas systems is of critical essence in rural energy and environmental decision-making. The present study concentrates on a Chinese context and attempts to explicitly investigate Environmental Kuznets Curve (EKC) applying heterogeneous panel cointegration methods, combining with distribution and characteristics of waste from livestock and poultry breeding for China's 31 provincial economies from 1991 to 2013. And, potentiality of biogas energy and its CO 2 emission reduction based on the utilization of waste is assessed. The empirical results indicate an inverted U-shaped Environmental Kuznets Curve in N indicator resulting from livestock and poultry breeding, where value of the turning point is approximately CNY 51,800. With economic growth and consumptive change, problems arising from animal husbandry mode can be increasingly great. There will be many major challenges to address these special environmental issues in rural area, especially in Central China and West China. Biogas production by animal excreta could be one of the most important rural energies and waste treatment patterns, which could reach 63.65 billion m 3 in 2013, equivalent to approximately 20% of natural gas used, and might offer a GHG reduction of more than 220 million tons of CO 2 eq. China should assign greater importance to special agricultural pollution and energy options in rural communities, in addition to 'beautiful countryside' propaganda.
