I remember as a kid working in the potato warehouses and noticing the
blow sand that makes up this part of the country, stuck to the potatoes and being sifted of of the conveyors...
With all the fertilizer and all the irrigation, that blow sand was more of a
muck type soil texture than a simple sand texture of soil,
because of all the organic matter the fertilizer and water had produced over years of growing potatoes...
So if you want to say that you produce SOM w/out adding any OM,,, then I have to say that nothing holds a candle to what the potato growers of CentroWisco have done...
