Wintertime land-applications of manure are a common practice because of the high
cost of manure storage (Srinivasan et al., 2006). However, the presence of frozen soil and
snow creates challenges for on-farm nutrient retention, as up to 75% of annual runoff can
occur during thaws (Good et al., 2012). Therefore, we 1) tested practical management
techniques that may reduce runoff on fields receiving winter applications of liquid dairy
manure, and 2) used a soil physics approach to identify weather and soil properties that
control infiltration, runoff, and nutrient losses during thaws.
