How to start a no-till garden from scratch

Laying down newspapers for a kill mulchLike Square Foot Gardening, Lee Reich's Weedless Gardening is really a rehashing of a lot of older methods that come down to creating permanent beds and keeping them mulched.  I liked Lee Reich's book a lot better because he included more hands on information that answered questions I've been tossing around about my similar gardening method.  For example --- can you start a no-till garden without an initial episode of tilling?  Lee Reich's answer can be paraphrased as "Yes, easily, and here's how..."

Starting a new no-till garden is a simple matter of laying down a kill mulch (also known as creating a lasagna bed or putting down a sheet mulch.)  Lee Reich first applies six cups of 5% nitrogen fertilizer per 100 square feet, then flattens or mows the existing vegetation so that it is as low to the ground as possible.  Next, he lays down a four-sheet-thick layer of newspaper and tops the paper off with one to three inches of mulch.  If he plans to plant into the bed immediately, that mulch would be compost, but the mulch could also be any of the materials I'll discuss tomorrow if you're making a bed for later use.  In his own garden, Lee Reich lays out compost as mulch in the permanent beds and wood chips as mulch in the aisles.

Lee Reich's weedless gardenI got a bit bogged down in Lee Reich's statement that he uses 5% nitrogen fertilizer, as well as by his later explanation that he uses soybean meal to give his garden a nitrogen boost every year.  As with Steve Solomon's complete organic fertilizer, I think that high nitrogen inputs like this may pass the "organic" test, but fail my permaculture test.  Adding nitrogen to the soil in any concentrated form kills off some of the beneficial soil microorganisms, and I can't help feeling that burning oil to cultivate fields of soybeans then using those soybeans to grow vegetables is about as far as you can get from a closed loop.  All of that said, Lee Reich has a valid point that you need a bit of high nitrogen at the beginning of the no-till process to counteract the high carbon of the weeds being killed.  Why not run chickens over that patch of ground instead, or toss down an equivalent amount of chicken manure?

No matter how you get the extra nitrogen to the soil, Lee Reich explains that you don't need to (nor should you) dig up your soil by hand or with a rototiller except in a few rare cases.  If you have to make drastic changes to your soil pH, you will need to dig the lime Lee Reich's gardenor sulfur into the soil, and if you're the unlucky inheritor of hardpan, you'll have to break up that tough soil layer before returning to no-till techniques.  Lee Reich is generally opposed to raised beds, which he notes dry out quickly (and require an initial round of digging), but he does admit that areas with bedrock just beneath the soil surface or with a very high water table (like we have) will benefit from raised beds.

In most cases, though, starting a new weedless garden is as simple as adding a nitrogen input, mowing, tossing down a layer of paper, and then topping it all of with mulch.  In less time than it would have taken to till the ground, you've created a new growing space and preserved the soil structure and organic matter.

•As far as mulch, your garden is much bigger than most gardens, perhaps bigger than it has to be. I grow a year round supply of vegetables for me and my family on a couple of thousand square feet of space. Wood chips, perhaps a couple of loads per year are delivered free. Leaves are delivered free or I pick them up in suburban neighborhoods. I make many tons of compost from garden and kitchen waste, hay scythed from a half acre field here, and, occasionally, some horse manure waste from a local horse farm.

•As far as the soybean meal, I've pretty much abandoned it. One inch depth of compost should supply all plants nutritional needs. Also, I question the killing of microorganisms from soybean meal; some will thrive on the N, others won't. The N is released slowly into the soil via the action of microorganisms. Chickens would mess up the garden and, anyway, don't provide free nitrogen if you feed them. (Mine get fed only enough to know where home is.) They mess up the beds so aren't allowed in my garden.

•Also, I could not get my chickens to drink from Avian Miser. Perhaps there was too much other water around for awhile. Perhaps they're too stupid.

I really appreciate you stopping by and adding in this valuable information! I love seeing what mulch you're finding --- cutting your own hay is one that I hadn't even considered.

I'm very sorry to hear you had trouble with our waterers! I sent you a slew of tips in an email, so hopefully that will turn your flock around. Chickens do seem to be creatures of habit, so if you're not able to take their old waterers away, they don't seem to try a new system.

Wow, I wish I would have found this page when I was considering moving to no-till (which I did anyway, as of last month). I'll be back to visit for more tips!

I'm glad I could help (albeit tardily.) I remember being intrigued when you commented with a link to your cover crop trials a few weeks ago, and can't quite figure out why I didn't add you to my reading list. I've subscribed to your blog now and look forward to following your adventures.

Hi Anna. I was just browsing at previous posts you've made to pick up as much information as i can.That's why i'm hovering at an older post.

Your comment : "and if you're the unlucky inheritor of hardpan, you'll have to break up that tough soil layer before returning to no-till techniques"

Well i was wondering, i live in Georgia with of course the infamous Georgia Clay. I've read of hardpan soil but was really unsure what it really meant. Is it just a place where water puddles to a great extent because it cannot infiltrate the soil? Because clay is hard stuff, no matter where you go in Georgia, so could it all be classified as hardpan? Also is it possible to break it up soley with deep rooted cover crops?(I know i hit on this alot. But i'm always curious about their uses)

Thanks Jalen

Hardpan is different from lots of clay soil --- we've got the latter, but not the former. Hardpan is a nearly rock-like layer of compacted soil that prevents water and roots from penetrating. It's generally formed when people run heavy equipment on damp soil, which compresses the ground below the normal plow depth. Some cover crops, like oilseed radishes, have been proven to be able to break through hardpan.

Unless you're growing in an area that has been plowed with heavy machinery for years or has otherwise been compacted (like being parked on by the family car), you probably just have lots of clay. The solution to clay is copious organic matter, which I'd add in the form of grain cover crops, compost, and mulch.

Thanks Anna. Also would you say your own style of permanent beds can be implemented on a large scale? I'm kind of caught up when you say Permanent beds. Aren't conventional rows in large scale agriculture really just long rows of like 1 inch wide beds with very narrow walk ways?
Comment by Jalen Wed Sep 28 20:49:00 2011

In conventional agriculture, the rows aren't permanent because you plow up the soil every year and then create new rows. The primary benefit of a permanent bed over tilling and creating rows every year is lack of soil compaction --- since you keep your walking, wheelbarrowing, etc., on the aisle, the permanent bed soil stays fluffy without tilling. Another benefit is efficient use of soil amendments --- you apply compost and mulch to the bed, not the aisles, so you're not wasting amendments on non-growing space. Add to that lack of tilling, which keeps organic matter in the soil rather than burning away. The combination tends to result in soil that gets better and better over time, rather than slowly degrading.

There is a machine you can pull with a tractor that makes long, semi-raised beds, but I don't think I'd say that my methods can be used on an industrial farming scale. The reason farmers till every year and use rows is so that they can come back through and till the aisles again for weed control with nearly no human effort. Conventional "no-till" farming tends to use herbicides to kill weeds, which is probably worse. So, no, you couldn't just scale my garden up and fix our food supply.

Personally, I think we need to scale our agriculture system down and have everyone growing their own food instead. I grow all of our vegetables, a good amount of our starches, and an increasing amount of our fruits and meat using the same amount of time the average American spends parked in front of the TV --- there is time in our lives to grow food if we want to take it.

Very well said, i couldn't agree more.

And also thank you for making this clear for me. I also look down on no till for their usage of herbicides instead of tilling the field to clear weeds. I'd rather them till in the weeds than throw chemicals on the fields where people's food is grown.

Anonymous --- Thanks for the agreement!

Jalen --- Keep asking questions. I enjoy answering them and am glad to meet someone else interested in the same agricultural issues I am. :-)
