[QUOTE="dontknowanything, post: 3413140, member: 38"] I don't think that is clear at all actually. For instance, it could be that tillage oxidises the OM at the beginning, with the resulting N release all in one go, whereas no-till may have the same oxidisation, but spread over the season so you never notice it in the plants. At the risk of sounding patronising, it's very dangerous to draw conclusions from observations like this, especially when you know the answer you want to find. I do agree with this; although the lab-heads will tell you that inorganic N destroys SOM, I think there is good evidence that it's outweighed by making more in the form of plant residue. I'll just drop this here again as I always do when the subject comes up, because I know [USER=386]@Feldspar[/USER] loves it [URL='http://thriplow-farms.co.uk/2015/03/03/day-62-pasture-rotations-som/']Day 62 – Pasture rotations & SOM[/URL] [/QUOTE]
