..GM crops .. reduction of erosion

Myth: Since 1996 GM crops have enabled a huge shift
to conservation tillage in USA.

Fact: During the period from 1996 (before GM crops) to
2002 the percentage of cropland acres in conservation
tillage in USA has remained nearly constant at 36-37 %.

Over the same period the percentage of cropland in
intensive tillage has increased from 38,5 % to 40,5 %.

USA had 2.3 million more acres in intensive tillage
in 2002 than it had in 1996 -- and 700,000 less acres
in conservation tillage.

I don't know what your calling conservation tillage,

You are interested in tillage system for soil
conservation in USA, and do not know the definition
of 'conservation tillage' in your national tillage
statistics? Gross.
