Wow, great information, as usual. I did not know about the difference in brown midrib sorghum. once again great practical knowledge base, Thanks Dale. Cheers from Oz.

Steel that is in direct sunlight is generally 30°f than the ambient temperature. So bare ground would be around the same, depending on moisture content and other factors. That has a major impact on the soil biome

Dale, would you believe as a youngster i lived in a kansas desert which could flood, frost, freeze or blow away about anytime. I was reared on an old farming operation with maybe 30 crossbred stock cows, 4 or 5 milk cows and an old international hand cranked cream seperator ,enuf hens for eggs and soup, alfalfa, wheat and/or milo crops on a rock farm 3 miles north of the Oregon trail or, 4 north of the Kansas river, approximately 29 miles west of Topeka. I got very interested in this cover crop lecture when you started discussing milo as a cover crop cause I am somewhat familiar with it. We rarely got a fence around the milo stubble in the fall so we usually missed that 'opportunity!!!.' As a kid I thought l worked too hard as it was. Still had to make time for baseball and basketball!! I got so charged listening about milo I wrote this while listening to your informative lecture.

Thank you.
