Minnesota Farmer


Dirty snow

100_3098

We’ve had a series of days with thawing temperatures and our snow is not white anymore, it’s very dirty.

Every snowflake has a bit of dirt in it, gathered as it forms, our snow here in Southwestern Minnesota has more than it’s share.  The winds of winter have been moving dirt along with the snow.  Now that it is melting, the dirt is left on the top.

We went into winter with dry topsoil.  Then the normal process of freezing soil squeezed more moisture out.  When our prairie winter winds come the soil starts to move.  Most of that soil doesn’t move far.  It falls behind some bit of plant material in the field or a low spot between dirt clumps.  Other bits may blow as far as the road ditch or a grove of trees.  Some little bits will stay airborne and help to start new snowflakes and rain drops.  It’s all part of the process of wind rain and snow.

Farmers in our area have come a long way since the dirty thirties.  Back then when you plowed ground you left it “smooth as a babies bottom.”  Smooth soil moves easier.  Today, farmers take pride in keeping winter soils rough with plenty of plant material sticking up.  Many will not till fields so they can help hold their soil.  We are well aware that soil is hard to replace, we need to keep it in place so our children can earn an income here also.

We’ll have white snow again before winter is over, it’s only January and there is lots of winter left.  Still I enjoy seeing some of that snow melt before spring, I just don’t like dirty snow.
