This is a pretty scholarly article with a lot of big words that I am not familiar with. I did a quick research on "prion" and I guess they are the agents which can cause certain diseases (including CWD) if they are in a "misfolded form" - not formed in a normal way.
I'm thinking that one of the reasons for the presence of clay being a contributing factor is that clay particles are very small compared with sand particles. Consequently, they pack together more tightly and reduce the ability of the soil to drain well enough for these nasty "prions" to leach away as they might in more sandy soil. When animals such as deer eat this soil in the normal process of browsing on forbes and grasses, they ingest the prions and become infected.
OK - I think I'm a little smarter now. Thanks for the report.
Thanks for the translation and summary. Makes it much easier to understand that way. I do have interest in this subject now but it's hard to understand some of the technical stuff that gets posted on it.
Let me start off by saying I am not a farmer.
I am a deer hunter and I do own a tractor and have all of the equipment - but that does not make you a farmer any more than standing in the garage makes you a car - well, you get the picture!
Having said that - and with most of my ineptitude fairly well hidden - I do think that buckwheat is one of the most under rated cover crops out there.
I say cover crop because I see mixed results as it relates to the deer eating the plants.
