Nutrients and sediment in frozen-ground runoff from no-till fields receiving liquid-dairy and solid-beef manures

Abstract: ] in any year) and any statistical differences in sediment concentrations among basins were not related to the presence or absence of manure or the amount of runoff. Concentrations and losses of total nitrogen and total phosphorus were significantly increased in basins that had either manure type applied less than one week preceding runoff. These increases occurred despite relatively low application rates. Lower concentrations and losses were measured in basins that had manure applied in fall and early winter … Show more

“…Measured and simulated runoff dissolved phosphorus (P) concentrations for the data of Komiskey et al (2011), with (a) no model input assumptions and (b) model assumptions that liquid dairy manure does not infiltrate into soil when snow is present and that winter‐applied solid beef manure had only 20% interaction with melting snow water and thus less P leaching and loss in runoff.…”

“…Studies of P loss in runoff from late fall or winter‐applied manure are limited, with most being observational at the plot to field scale. Most research was conducted before 1980 (Converse et al, 1976; Klausner et al, 1976; Young and Mutchler, 1976; Young and Holt, 1977; Phillips et al, 1981; Steenhuis et al, 1981), with some more recently (Hansen et al, 2000; Ulén, 2003; Lewis and Makarewicz, 2009; Komiskey et al, 2011; Owens et al, 2011). Observed P loss varied, generally because of variable weather and hydrology from year to year.…”

“…Second, and more importantly, these inter-annual climatological variations would not be expected to impact only Brown and Manitowoc counties, rather, if significant they should have impacted all four analyzed counties. What is more likely important for limiting spring infiltration is the percentage of ice-filled soil pores, which is a complex function of freeze-thaw cycles and winter rain precipitation events [49]. Therefore, we feel that these potential confounding factors were not likely of first-order importance in the observed changes in water quality.…”

“…Frozen ground has been identified as a critical factor in BWIs and well water contamination [49,50]. When the ground is frozen, snowmelt and/or precipitation infiltrate more slowly, as some of the pores between soil particles that normally allow for infiltration are filled with frozen water.…”
