Subject: RE: No-till saves nitrogen costs


southern MN
Well, the N has to come from somewhere. Legumes can create n but we aren’t involving them; so we are only depleting, recycling, or storing the given amount of N the soil has. And then adding N for the crop from there.

We are told it will be worth a lot of money to store the n away forever in the soil as carbon. This should remove n and actually require more applied n to grow a crop.

But now we are told the biology will release extra N which is good for farming.

But then we were told tillage releases N and that is a problem and bad for farming.

So, are we storing it away, are we releasing it, is it good or is it bad to be releasing N, or does it depend on who is giving the speech about it?

It starts to sound like the fu fu juice that adds 3-5 bu of beans for $15. The messages are pretty conflicting when you look at all of them?

Not picking on anyone, just can’t wrap my head around the fairly obvious multiple standards here? It’s like the blind guys looking at an elephant and each feels a different part but no one is looking at the whole critter and seeing it all.
