“…It appears that the high mean annual NO 3 -N concentration in 2008 and 2010 might not primarily be directly associated with the exceptionally high precipitation but is likely be attributed to the high NO 3 -N concentration in the spring. High storm flows generally resulted in low NO 3 -N concentrations (figure 3), which could be due to the dilution effect by precipitation (Mendez et al 1999). The application of N fertilizers and wet field conditions likely contributed to the high NO 3 -N concentration in the spring of the corn years (2008 and 2010).…”

“…The width of PFS along the primary flow path at the footslope ranged between 37 to 78 m (121 to 256 ft) regardless of PFS treatment. Previous research revealed that much of particulate contaminants were trapped upslope or within the first meters of filter strips, resulting in almost the same effectiveness in trapping efficiency for filters with different widths (Mendez et al 1999;Liu et al 2008). The greater filter strip area might also facilitate greater uptake of nutrients by plants (Dosskey et al 2010).…”

Nitrogen (N) and phosphorus (P) from agricultural landscapes have been identified as primary sources of excess nutrients in aquatic systems. The main objective of this study was to evaluate the effectiveness of prairie filter strips (PFS) in removing nutrients from cropland runoff in 12 small watersheds in central Iowa. Four treatments with PFS of different spatial coverage and distribution (No-PFS, 10% PFS, 10% PFS with strips, and 20% PFS with strips) were arranged in a balanced incomplete block design across four blocks in 2007. A no-tillage two-year corn (Zea mays L.) -soybean (Glycine max [L.] Merr.) rotation was grown in row-cropped areas beginning in 2007. Runoff was monitored by H flumes, and runoff water samples were collected during the growing seasons to determine concentrations of nitrate-nitrogen (NO 3 -N), total nitrogen (TN) and total phosphorus (TP) through 2011. Overall, the presence of PFS reduced mean annual NO 3 -N, TN, and TP concentrations by 35%, 73%, and 82%, respectively, and reduced annual NO 3 -N, TN, and TP losses by 67%, 84%, and 90%, respectively. However, the amount and distribution of PFS had no significant impact on runoff and nutrient yields. The findings suggest that utilization of PFS at the footslope position of annual row crop systems provides an effective approach to reducing nutrient loss in runoff from small agricultural watersheds.

“…Many studies have evaluated the performance of VFS in removing sediment (Robinson et al, 1996), nutrients (Chaubey et al, 1994;Mendez et al, 1999;Abu-Zreig et al, 2003;Blanco-Canq ui et al, 2004) and pathogens (Lim et al, 1998;Coyne et al, 1998;Williamson et al, 1999;Entry et al, 2000;Atwill et al, 2002;Tate et al, 2004;Trask et al, 2004;Tate et al, 2006;Mankin et al, 2006).

Diffuse water pollution from agriculture (DWPA) is a major environmental concern, with significant adverse impacts on both human and ecosystem health. However, without an appropriate understanding of the multiple factors impacting on water, mitigation measures cannot be targeted. Therefore, this paper addresses this gap in understanding, reporting the hydrochemical monitoring evidence collected from the UK Government's Demonstration Test Catchments (DTC) programme including contrasting chalk and clay/mudstone catchments. We use data collected at daily and sub-daily frequency over multiple sites to address: (1) How does the behaviour of the full range of nitrogen (N) species and phosphorus (P) fractions vary? (2) How do N species and P fractions vary inter-and intra-annually? (3) What do these data indicate about the primary pollution sources? And (4) which diffuse pollution mitigation measures are appropriate in our study landscapes? Key differences in the rates of flux of nutrients were identified, dependent on catchment characteristics. Full N speciation and P fractionation, together with dissolved organic carbon (DOC) enabled identification of the most likely contributing sources in each catchment. Nitrate (NO 3 -N) was the dominant N fraction in the chalk G R A P H I C A L A B S T R A C T a b s t r a c t a r t i c l e i n f o Contents lists available at ScienceDirectScience of the Total Environment j o u r n a l h o m e p a g e : w w w . e l s e v i e r . c o m / l o c a t e / s c i t o t e n v whereas organic and particulate N comprised the majority of the load in the clay/mudstone catchments. Despite current legislation, orthophosphate (PO 4 -P) was not found to be the dominant form of P in any of the catchments monitored. The chalk sub-catchments had the largest proportion of inorganic/dissolved organic P (DOP), accompanied by episodic delivery of particulate P (PP). Contrastingly, the clay/mudstone sub-catchments loads were dominated by PP and DOP. Thus, our results show that by monitoring both the inorganic and organic fractions a more complete picture of catchment nutrient fluxes can be determined, and sources of pollution pin-pointed. Ultimately, policy and management to bring nutrient impacts under control...
