Plan Now for Snow Trapping

In the drier regions of the prairies, farmers always want to take advantage of available moisture since we all know how unpredictable the availability of moisture can be. Catching snow in the stubble is one-method farmers can use to increase the potential of stored soil moisture for the spring. However, it is often a neglected practice in the rush to get the crop in the bin. Snow trapping can result in significantly more stored moisture in the soil and if it is a dry spring, can make the difference in getting the crop started. There are a variety of methods to trap snow; high-low stubble cutting, leaving barrier strips of crop, permanent barrier strips, even leaving tall stubble. However, one must plan ahead to do this and also make sure that the seeding system you are using in the spring can go through the stubble. The important thing is that even with minimal amounts of snow in the winter, it is amazing how much moisture can be trapped in those fields.
