Oh, great.. this might be just the thing I have been looking for. I have already ordered it.

Sort of off topic, but I wonder if you wouldnt mind saying what kind of oats you use for winter cover crop. Was wo dering if I could just buy horse oats and use those?

Deb --- I suspect you'll enjoy the book!

About oats --- we get whatever variety they have in 50 pound bags at the feed store. My garden spreadsheet says this has included Ogles, Noble, Common, and unlabeled varieties. The only problem we had was last year when I grazed the oats hard and they didn't winterkill, but I'm 99% sure that was the grazing and not the variety.

I'm not sure what horse oats are. If they're processed somehow for feed, they possibly might not sprout. But otherwise it should work. And the feed store is definitely the cheapest place to get cover crop seeds (by an order of magnitude sometimes!).

Excellent book! He's also an excellent speaker if you ever have a chance to attend a workshop in your area.

Oat variety does matter, or actually type. Spring oats, aka white oats may winter kill if you have cold enough weather,fall oats aka grey oats will not winter kill because they are meant to survive winter for a spring crop of grain. It's hard to know what you're getting if you just buy feed oats, as seed crops are much cleaner, meaning less weed seeds by law. So if you want oats to have a chance to winterkill, buy white oats. Even seed sellers get confused if you ask for oats to plant in the fall, because they assume you want them to survive. We never get cold enough weather for winterkill oats or barley, so I'm switching to sudan grass which really puts on biomass. With no irrigation, my sudan is already a foot tall + in less than a month.

Since I didn't know what a caterpillar tunnel is I googled it, and came across this article.

Some quotes:

They use a caterpillar for lettuce, spinach, salad mix, cucumbers, tomatoes, basil, chard and kale. [They use] Enviromesh anti-insect screen and 6-mil greenhouse poly on a caterpillar.

and

The caterpillar also saved the Nordell’s tomato crop last year. In the field, the first tomato harvest is normally the third week of August. But late blight, which was rampant all over the East in 2009, killed their field tomatoes in mid-July, before they started producing. But the tomatoes in caterpillars started bearing in early July and kept on going until late August, when they finally succumbed to late blight. In other words, the caterpillar provided six weeks of earliness and six weeks of late blight protection.

Thanks Anna and Nita for the oats comments. I meant feed oats when I said "horse oats".
I have used caterpillar tunnels, and find that theu provide about 4 degrees of frost protection.... with just the agribon row cover. With plastic, its more than that. I make mine out of 10 ft. Pvc, and make the hoops about 4 feet tall.
