i have been out and about this saturday morning...after a trip to campus i wandered out to an office supply store for some printer ink. markers, post-it flags, and some pens and on the road home i stopped by the corn field out on county line road just to see if anything was up...with snow, thaw, rain, snow as the pattern the winter has established i thought there might be something...and there was...the second and smaller of the erosion gullies ( top photo ) i found has gotten a bit bigger and the one from last year ( bottom photo ) continues to grow...you cna see form all three photos that farmer brown has left the con stubble in the field after harvest which will help ( but, obviously from the photos, not stop ) the topsoil from running off with rain and snow melt...you can just see in the middle photo the unbroken snow on the soybean field which was harvested clean and has no stubble...that particular portion of the field however has a grass strip about six feet wide between it and the the drainage ditch at the edge of the road which is absent from the corn field and which is hold back any erosion form that particular portion of the field...whatever sort of precipitation falls for the duration of the winter i would expect both these gullies to enlarge...we'll see if i am correct in that supposition as the season wears on and i make field trips out there as time and weather premit.
