Growing Corn in the Desert Without Supplemental Water or Compost

Imagine planting corn in the desert (less than 11 inches rainfall) by digging down ~10 inches or more to moist earth, dropping a cluster of ~15 seeds, then covering with original soil in the order the soil was removed.
Now imagine sustaining a thriving culture for many hundreds of years with this corn as the primary food source. Sounds impossible?
I plan to try the Hopi method this season using the research provided by the Crow Canyon Archaeological Center in, The Pueblo Farming Project. The research site is in Colorado and the researchers include Hopi farmers. Now that it is winter here in New Mexico, I am mapping out nearby locations (both on my own and other unmaintained properties) where I can follow the planting method and observe what happens here.
Please take a look at the amazing site and its research. If you have tried these methods, please share your experiences and/or guidance to help fellow desert growers achieve optimal results.

We have had some success with blue corn on the highest, driest, most exposed part of our property - but it was not by digging down. The caliche here (south of Santa Fe in the rain shadow between the Sandia and the Sangres) is formidable. That said, a pretty neglected mound of aged manure and a little but of drip irrigation during the longest spells of drought went a long way. Most of our attempts at outdoor gardening are thwarted by giant grasshoppers and desiccating winds. The corn thrived and produced - planted in early July right as the monsoons started.

Thank you for sharing your experience Leslie:

Like you Leslie, last year I had a successful crop of Hopi blue corn using irrigation and rotted horse manure. But after reading about the Hopi way of reading the land and planting without additional water or manure, I felt like I was missing a unique opportunity to develop my skills. I want to experience the challenge of learning how to work with Nature's constraints and improve my skills at reading the land.
As I read this study, I begin to see that there are complex reasons behind the many subtle decisions about where and how to plant corn the Hopi way. I can begin to recognize two purposes of planting deep. One is to give the seedlings enough moisture to germinate and the other is to establish a strong root system during the pre-monsoon period. By the time the monsoons arrive in July, the corn plants probably have the strength they need to withstand the torrential surface flooding, at least that is what I'd like to observe to see if that's true.
At this time, reading the land involves recognizing the locations where corn may thrive in existing conditions. For example the Pueblo Farming Project (PFP) notes:

Rabbitbrush and snakeweed are two plants they see as indicating prime areas

Healthy sagebrush and four-wing salt bush were also identified as potentially promising locations. Washes and places with signs of run-off collecting from nearby slopes indicate greater moisture under the soil surface. Looking for signs of water awakens my senses and cultivates my own roots in this desert.

I grow corn descended from Hopi. Without irrigation. I can plant them at least 8" deep and get good germination. The Hopi corn has a special hypocotyl that stretches more than other types of corn.

There are several good films on youtube about growing growing Hopi corn. "Michael Kotutwa Johnson" is a good place to look.

Fantastically helpful thread that you put together Fish! Your intuition based on experience is very helpful, for example:

I also did a test this time and these seeds amazingly germinated at a depth of 8”. I’m going to plant up to 10-12” next time and see if that helps with better rooting and plant stability. I had a lot fall over from the heavy rains and winds.

As Leslie also noted above, the winds can be fierce out here in the Southwest. Dedication in the face of winds, drought conditions, followed by monsoons have led to many creative planting strategies. Please keep sharing your results.
I'm looking forward to watching all the "Michael Kotutwa Johnson" videos. Thank you for documenting your years of experience.

interesting thread. i was aware of the deep planting but this thread has brought up a couple of things i either missed or forgot last time i looked at this method...

1) putting the soil back in the order it was dug up
2) using the right type of hopi corn that has been selected for pushing thru nearly a foot of soil.

1) is easy, I'll try that... but how important is 2)?
With bog standard corn, do i just plant more in the hole to get more chance of success, or can i go halves on the method going maybe 4 or 6 inches deep rather than 8 or 12?

My understanding is that the Hopi people do not sell their corn seed. The corn seed has been selected by the Hopi and for the Hopi from time immemorial and is perfectly adapted to their unique ecogeographical area. Some companies use the word “Hopi” in the seed names but the genetic authenticity is questionable.
What I have gleaned from reading the tremendous work on “landrace” here on permies and in Toward an Evolved Concept of Landrace is that each of us must locate non-GMO seed that grows in our area.
The teachings of the Hopi are vast. The insights involve careful observation of the contours of the surrounding land and how seasonal rains plus organic debris move and collect on that land. Choosing how deep to plant is based on observation of soil moisture and much more. The situation for each planting location will be unique and require much trial and error learning. Instead of a simple recipe for success, we have clues given by the Hopi. Beyond that, each of us must each go on a distinctive adventure in partnership with the land entrusted to our keeping.

I tried this at my old property in Socorro County, and it worked really well.. until the neighboring ranches cattle barged in and ate it all! Fence out..

thank you for sharing this - really interesting!

I really love the reminder of how much it matters to take a look at what is around us in the area we hope to grow food in, what it's telling us about the conditions there.

Although so interesting about the saltbush. I'm in southern AZ, and in my area, one reason saltbush is a sign of a good site to grow other plants is because it absorbs a lot of salt and calcium (and puts them into the leaves, which can be burned and make a culinary ash that can be eaten ^_^), and that's a good thing for my particular soil type.

I am not sure if it would be possible to grow corn here without irrigation. The heat here is quite a bit higher than up north in the project area, and we get 1-2 inches less rain annually, so it may just be too hot with too little rainfall to manage. But it would be worth exploring how little water could be used, I think.

I am going to try this in spring. I will be planting in a pinyon-juniper area, in a basin surrounded by hills. The area should recieve 20+ acres of run off. Rabbitbrush, cholla, and prickly pear dominant the area.
