Effects of Manure and Tillage on Edge‐of‐Field Phosphorus Loss in Seasonally Frozen Landscapes

Abstract: Environmental conditions and management practices affect nutrient losses in surface runoff, but their relative impacts on phosphorus (P) loss during frozen and nonfrozen ground periods have not been well quantified. More specifically, the relative importance of manure application, tillage, and soil-test P (STP) has not been assessed at the field scale. In this study, we compiled a dataset composed of 125 site-years of data from 26 fields that were continually monitored for edge-of-field P loss during snowmelt … Show more

“…Results from the current study showed similar trends, whereby STP accumulated due to P surpluses, resulting in concomitantly greater annual runoff DRP FWMC. Indeed, Zopp et al (2019), using a regression tree analysis, found that STP concentration was the most important factor in predicting DRP FWMC at the field scale. Despite greater cumulative P balances, greater accumulation of soil P (as evidenced by increased Mehlich-3P concentration), and a large fraction of soil total P in labile fractions (Waldrip et al, 2015), row crops in the current study had relatively lower risk of DRP loss compared with pastures with lower poultry litter application rates, lower STP concentration, and only small changes in labile P pools over time (Figure 4).…”

“…Winter application of manure combined with snowmelt could carry manure-derived DOM from these lands to groundwater and surface waters of adjacent waterways (e.g. Lewis and Makarewicz 2009;Zopp et al 2019). The concurrent low discharge observed during winter months (Fig.…”

“…A diagram showing key agronomic, biogeochemical, and hydrological characteristics influencing nutrient losses in cold agricultural regions. The papers in this special section investigate different aspects of these characteristics, including the importance of the nongrowing season (Good et al, 2019; Plach et al, 2019; Ulén et al, 2019) and snowmelt (Hoffman et al, 2019; Kokulan et al, 2019; Wilson et al, 2019a) in annual flow and nutrient transport, the impacts of vegetative nutrient release (Cober et al, 2019; Costa et al, 2019; Liu et al, 2019b; Schneider et al, 2019; Vanrobaeys et al, 2019), the impacts of winter and fall nutrient applications (He et al, 2019; Sadhukhan et al, 2019; Smith et al, 2019; Stock et al, 2019; Vadas et al, 2019; Vetsch et al, 2019; Zopp et al, 2019), the influence of soil on nutrient loss (Dharmakeerthi et al, 2019; Liu et al, 2019a; Satchithanantham et al, 2019; Wilson et al, 2019b), and the patterns of nutrient concentrations in streams (Casson et al, 2019). …”

“…Nutrient rate management Implementing soil drawdown practice by reducing P input in combination with crop removal reduces total dissolved P concentrations in both snowmelt and rainfall runoff without affecting crop yields (Liu et al, 2019a). Maintaining low or moderate soil test P to reduce P concentrations and loads in snowmelt runoff (Wilson et al, 2019b;Zopp et al, 2019). Decreasing N application rates reduces nitrate leaching in tile drainage (Vetsch et al, 2019).…”
