Twin Oaks Garden blog, rainy day reading, more on hydroponics.

Y-Star Pattypan squash, one of the varieties for the Twin Oaks Garden this year.

Wren, one of the Twin Oaks Garden Managers, has started a blog about the Twin Oaks Garden. This is a great place to check what’s happening in our garden, especially if you also garden in Virginia or some other winter-hardiness zone 7 area.

The new post this week is about What’s New in Spring 2018. There are photos of people at work and also of the new varieties we’re growing this year: Southern Giant Curled Mustard, Purple Peacock broccoli/kale, Canary melon, Flavorburst yellow bell pepper, Y-Star pattypan squash, Royal Burgundy beans (not new to us, but back again), Granny Cantrell’s tomato and Persimmon tomato.

The March issue of Growing for Market is out. Nothing from me this time, but plenty of good stuff from other farmer-writers. Diane Szukovathy writes about starting a 12-member flower producer’s co-op in Seattle. They started with a part-time employee and a simple leased space, working on an indoor farmer’s market model where each farm conducted its own business under a shared roof. They were able to get some USDA funding, and increased their income immediately. Their shared setting was attractive to customers, and a good way to mentor newer growers.

Jesse Frost has written on Understanding Early Blight, with a lot of solid information from Meg McGrath at Cornell (home of the Vegetable MD Online site). Carolina Lees writes about Healthcare beyond hospitals: farm-hospital connections. Ellen Polishuk of Potomac Vegetable Farms offers a Farmer to farmer profile of Richard Wiswall (author of The Organic Farmer’s Business Handbook and designer of many labor-saving devices.) Morgan Houk writes about only collecting useful information when record-keeping, not piles of data you’ll never use. John Hendrickson brings us the latest news on the paper pot transplanter (still not certifiable for USDA Organic farms).

The Spring 2018 Heirloom Gardener magazine has an article from me about Intercropping (planting two crops side by side in the space normally reserved for just one. In early spring we often sow snap peas down the center of a spinach bed (either an overwinterred spinach bed, or a spring-planted one). The same piece of rowcover warms both (until we whisk away the rowcover to a later crop. The peas grow upwards, not competing with the spinach. When the spinach bolts, the next crop is in place with no further work.

In the summer we have sown peanuts down the center of a bed of lettuce, and transplanted okra into a bed of early cabbage. It’s all about timing and about choosing compatible crops. Okra grows tall, while cabbages stay close to the ground. peanuts grow slowly while lettuce grows quickly.

Lastly I have more on hydroponics and Organic Certification.

Last week I wrote about the November 2017 vote at the National Organic Standards Board (NOSB) on hydroponics. Since then I’ve read more information, and realized that the view I presented last time is not the whole picture. It is more complex. Audrey Alwell wrote in the Organic Broadcaster for Jan/Feb 2018, reminding us that the 8:7 vote at the NOSB is not a clear stamp of approval for “organic” hydroponics and aquaponics. The NOSB rules require a “decisive vote” (10:5) for a decision. They did not get a decisive vote to prohibit hydroponics from Organic Certification. This means the situation continues for now as it has been. That is, Organic certifiers can certify hydroponic operations of growers using only approved inputs for fertility and pest management, and if they are protecting natural resources and fostering biodiversity.

The Organic label does not cover all the important aspects of ethical and sustainable farming. Not all Organic practices are sustainable. (Think about removing and trashing plastic mulch!) Social justice and fair trade are not addressed. Some hydroponic  growers use renewable energy, some see hydroponics as more sustainable than Organic. In California, during the 6 year drought, hydroponics helped some farmers survive and produce food. Adaptability is important.

One USDA-accredited certifier, CCOF, says all producers should be pushed towards using renewable energy, in order to reduce impact on natural resources. CCOF submitted a 12-page comment.

Keep the Soil in Organic, Mother Earth News, winter reading

Did you know that nearly all the supermarket “organic” tomatoes are not grown in soil drawing the nutrients they need from the complex array in the soil, but in an inert material (rockwool, coir or plastic pipes with holes in), receiving as nutrients only what the growers provide in a solution that passes by the roots?

Did you know that your understanding of “organic” might be different from USDA’s? Driscoll’s Berries has over a thousand acres of “organic” hydroponic production in hoophouses in California and Mexico. They are the biggest hydroponic “organic” producer in the world.

Did you know that hydroponics is large-scale? Melody Meyers of UNFI testified at the National Organic Standards Board (NOSB) that her company’s hydroponic “organic” sales exceeded $50,000,000. (Wholesale value – double it to get the retail value.)

Dave Chapman said

One of the challenges of the USDA takeover of organic certification has been the loss of involvement on the part of the organic farmers. As we have all struggled to make a living in a tough arena, it has been easy to give into a sense of helplessness around maintaining strong standards. At the same time that organic farmers have retreated from the process, the USDA has been profoundly influenced by large corporate farming interests.

Three quarters of US hydroponics sales go to only three or four farms – this is a huge concentration of money, power, and influence in a very few hands. And the industry is engaging in heavy lobbying, not just at NOSB, but throughout the United States Department of Agriculture (USDA).

How did this happen? How did “organic farming” change so drastically in six years? My report is based on Dave Chapman’s in his blog Keep the Soil in Organic.

In 2010, the NOSB recommended saying no to hydroponics receiving Organic Certification by a 14:1 vote, in keeping with international standards, the federal law (the Organic Foods Production Act, OFPA) that created the National Organic Program (NOP), and the traditional practices of organic farmers.

At the NOSB meeting in fall 2016, despite hydroponics industry lobbying, there was not enough support to vote to overturn the 2010 recommendation and allow hydroponics, aquaponics and bioponics. (This would have needed a 2/3 majority). Also, the proposal (from the Crops Subcommittee) that would have eliminated hydroponics in organic was sent back for reconsideration. The stalemate means that the NOP will continue to certify “organic” hydroponic operations.

Dave Chapman reported that

Food Democracy Now! presented a petition with over 12,000 signatures to reject hydroponics. Cornucopia Institute presented 1400 proxy letters from farmers and eaters demanding that soil stewardship be a requirement for organic certification. Clearly, the people numbers were on the side of the soil.

National Organic Program (NOP)  director Miles McEvoy stated at the meeting that even if the recommendation allowing hydroponics was defeated, it would not affect NOP policy. The NOP continues to support certifying hydroponics as USDA Organic even though the OFPA law requires Organic farming be based on maintaining and improving soil fertility. The NOP support of hydroponics is also in direct opposition to the 2010 NOSB recommendation, as well as standards in most other countries. Across the world, hydroponic operations are being USDA Organic certified.

A resolution  passed 12 to 0 reading, “It is the consensus of the NOSB to prohibit hydroponic systems that have an entirely water-based substrate.” (This refers to “plastic pipe” hydroponics as opposed to rockwool and coir which are imagined to provide something more than physical support.) This resolution does show consensus in rejecting the idea that hydroponic growing can become organic simply by “adding biology” to plain water, and provides a small glimmer of sanity and common sense. NOSB refused to acknowledge that actual hydroponic farming is not limited to plants that grow in water, but includes those propped up by rockwool and coir. The current hydroponics industry move is to avoid the “H word” and talk about “containerized ” plants – ones held in a small amount of material, but still being fertilized by solutions flowing by.

What makes a system hydroponic is how the fertility is delivered to the plant, not the material that the roots sit in. In a hydroponic system, the fertility is supplied to the plant in the irrigation water. There are so-called “organic” fertilizers that are extremely processed organic materials. For example, the 16-0-0 hydrolyzed soy protein being used in hydroponics acts like a synthetic nitrogen fertilizer. It has little similarity to unprocessed soy meal. In a genuinely organic system, the fertility results from the  complex soil food web interacting with organic materials we growers supply.

The companies speaking in support of hydroponics to the NOSB include Miracle Gro (chemical fertilizer company), Nature Gro (major supplier of substrates for conventional growers), the Organic Trade Association (lobbyists for the big hydroponic “organic” growers), Nature Sweet tomatoes (1400 acres of conventional greenhouses), Houweling’s Tomatoes (250 acres of conventional greenhouse tomatoes), and Driscoll’s (already mentioned).

These companies all want  to get in on the “Organic” market without doing the honest hard work. The food industry spends more money lobbying Capitol Hill each year than the defense industry does!

Know your farmer! Buy local, from trusted growers. Do what you can to speak up for real food, grown in the soil.

I wrote about our winter lettuce (a summary of blog posts here) for Mother Earth News Organic Gardening blog. You can read it here.

peerj-04-1582-g005Margaret Roach at A Way to Garden has had some interesting blog posts recently. One is about a recent study called “Arthropods of the Great Indoors: Characterizing Diversity Inside Urban and Suburban Homes,” and its lead author is Dr. Matthew Bertone. We are hosting an average of over 90 different arthropod types per home! I’ve noticed that we’ve accidentally brought camel crickets from our root cellar into our bathroom! I’ve been reducing their numbers. . .  They don’t appear to be in top 12 found in most people’s homes according to this article.

This post on Do Home Remedies for Weeds or Garden Pests Work? is a careful look at the options often recommended by others, with cautions about pouring lots of Epsom salts, vinegar, clove oil on your plants and soil.

Her Special Weed Issue has links to a lot of useful weed topics, as well as info on a  Baby Birds book with delightful-looking watercolors.
