Neglected land...what to do?

got to look into that. Another interesting path to go down.

Is salt benign?

[FarmRanger]

Salt can be benign if the amounts are small
enough. A half litre of 360 gram/litre glyphosate
would put 180 grams of salt on an acre.

If salt is the concern, I seriously doubt that the
addition of 180 grams over an entire acres will
make much difference.

The link to magnesium is being made due to the fact that part of the way glyphosate works is that it binds to Mg and Zn therefore preventing other process from occuring. The idea is that in the future those element remain tied up by glyphosate. Another concern that is gaining some recognition is that glyphosate stress inreases lignation (insoluble fibre) and therefore ties up larger amounts of potassium for longer periods of time in the residue.
