Measuring alfalfa winter survival in controlled environments. Agricultural and forest Meterology 57: 243-251. Snow depth required for near steady-state soil temperatures. Fall dormancy and snow depth effects on winterkill of alfalfa. ![]() SourcesMinnesota State Climatology office. In addition to runoff risks and environmental degradation, manure can absorb the sun’s energy and cause premature melting of the snow. ![]() Do not apply manure to snow in late fall or winter.Minimize snow compaction in fields from traffic by snowmobiles or other vehicles.Leave stubble in the field to catch and hold snow.Here are some snow management strategies to consider: Snow management Snow is likely during most winters in Minnesota, but the timing and amount are difficult to predict in many regions where forages are widely grown. Winter survival rating where 2 is very winterhardy while 5 is not winterhardy. Data averaged for two years of extreme minimum air temperatures in Chathum, MI. Table 1. Effects of snow depth (0, 4, and 8 inches) on winterkill of alfalfa varieties differing in winter survival. In addition, some alfalfa breeding companies have selected alfalfa varieties that have a combination of physiological features that increase cold tolerance. An average killing temperature of 15 F is often quoted for acclimated alfalfa, but varieties vary greatly in cold tolerance which is influenced by traits such as fall dormancy and crown depth. Cold tolerance is a key component of winter survival and cold tolerance is typically greatest during the months of January and February. Snow and alfalfaWinter survival of alfalfa is affected by genetics, environment, disease, and management factors. Temperatures of 40 F and above can cause alfalfa to prematurely break dormancy during winter and be susceptible to subsequent freezing due to resumption of normal winter air temperatures. Snow reflects solar energy and reduces absorption of energy that can cause soil warming during the winter months.During periods of very low air temperatures in early and late December, the soil was covered with snow between 4 and 12 inches. Alfalfa crowns are also protected from air temperatures because crowns are typically buried from 1-2 inches in the soil.įigure 2. Figure 2 shows rather constant soil temperatures in December 2022 during periods of very low air temperatures with snow depths from 4 to 12 inches. Snow depths of 4 to 10 inches have been shown to provide effective insulation. Snow depth is critical to insulating the soil.Fluffy new snow provides the best insulation while partially melted snow transformed to ice is a poor insulator. Snowpack often has layers of snow with different structure. Snow structure - Snow varies considerably in moisture content, particle size, and density and continually undergoes change as it ages.Snow cover protects dormant alfalfa plants from freezing and desiccating and reduces the depth and duration of soil freezing (Figure 1). It is a natural insulator of the soil and buffers against low and fluctuating air temperature. ![]() Snow as an insulator - Snow is a mixture of air and ice and has low thermal conductivity compared to pure ice and soil.So far this winter, the risk of alfalfa winter kill is minimal because throughout much of Minnesota the plants have been well insulated by snow during periods of very low air temperatures. Winter snowfall provides recreational activities, snow shoveling, and travel disruption, but for hibernating alfalfa, it provides a blanket of protection against winter air temperatures. Stubble can catch snow in the field and can also reduce injury An alfalfa field covered with 4 inches of snow.
