Hello everyone,

I'm not aware of any direct comparisons of CRP and MiG, but there have been
several studies looking at conversion of former CRP fields into pasture.
The results of these vary, probably more as a result of the grazing
management practices than anything else. A study done in NY showed no
difference in erosion, one done in Missouri showed no erosion differences,
but increases in runoff when CRP fields were grazed or hayed, one in Wyoming
showed more erosion. This makes the point that this is all site specific
and management specific, but one thing that everyone can agree on, I think,
is that both CRP and MiG are significantly better than crop ground, even
no-till crop ground.

Here in Wisconsin, we compared grazed vs. ungrazed/buffered riparian areas
and found that streambanks that had well-managed grazing applied controlled
erosion as well as grassy buffer strips and had less erosion than unmanaged
streambanks that had been allowed to grow up to trees.

We also found in several of our studies that more species of grassland birds
are attracted to the habitat structure created by grazed or harvested
grasslands than attracted to unmanaged grasslands, including CRP fields.

The take home message here is that well-managed pasture is vastly superior
to any other cropping system in terms of conservation value. And that areas
set aside specifically for conservation and wildlife purposes can often be
improved using well-managed grazing.

Here's a website that has some information on grasslands and wildlife:

Hope that's what you were looking for, Russ!

Best regards,

In Wisconsin studies have shown that CRP land results in
more erosion than managed grazing land.
Maybe Laura P could help with a reference?
