 Refering to previous thread where i showed soil temperature comparisons between strip-till and conventional till. It showed  for the most part the temperature in the strip-till was higher.

 The question was raised why that was. You would think they would be about the same or the strip-till would be a little bit cooler.

After reading the following link (page 3) it can happen that way.

http://www.precisiontillage.com/assets/uploads/Root%20growth_temp_important2007.pdf

When strip-tillage has occurred in the late-fall or early winter

exposing the soil surface to radiant heat from the sun and moving residue off to the side between the row,

soil temperatures climb 4 to 9°F compared to what is under the residues and sometimes 1 to 5°F warmer

than conventional tilled ground.




 Here is my spin. In the conventionally tilled the suns radiation is spread across the whole soil surface but in the strip-till most of it is reflected by the surface residue. Is it possible that the bare strip is getting a little more radiation besides what is directly hitting it, by some refected by the residue heating the strip even more?
