[Terrapreta] TP and prairie soils

[Janice Stettler]

I don't wish to add an additional layer of complexity to discussions of soil fertility in the plains, but a rather massive soil organism numbering by some estimates, 98 million, may be responsible.  The American bison migrated from Canada to Mexico in a broad swath consuming prairie grass and producing ruminant waste scuffled into the soil by their sharp hooves.  For aeons they were integral part of prairie ecology and probably the closest thing to Lil Abner's schmoo with a real living heart beat.  As a farmer I know poop and ruminant poop is unequaled for residual effect.
