High Tunnel Construction Workshop Summary

May 8th, 2012 @ 1:42 pm by Sally

Practical Farmers of Iowa hosted a two-day high tunnel construction workshop at TableTop Farm in rural Nevada, IA April 23-34. Thirty people came to consecutively learn and help construct a tunnel during this immersion workshop. -blog continues below gallery-

 

High tunnels are a hot item on Iowa fruit and vegetable farms, and for good reason—high tunnels can offer opportunities for farmers to significantly extend their season without supplemental heat, and also offer a protected environment during the main season. This has proven instrumental for Iowa farmers like Jill Beebout and Sean Skeehan from Blue Gate Farm near Chariton who relied heavily on high tunnel crops in recent years due to volatile weather events. Here are some records of their high tunnel schedules for the past few seasons: Winter Season 3, Season 3, Season 2, Season 1.

Tomato Grafting Workshop at The Homestead

April 4th, 2012 @ 3:14 pm by Tomoko

About 20 enthusiastic farmers/gardeners gathered together last Friday to learn how to successfully graft tomatoes.

At the beginning of the workshop, Eric Armbrecht told us about The Homestead, the living and learning center for people with autism, who hosted the workshop. Sally Worley from PFI then gave the overview of grafting history, explaining how grafting has a long history in horticulture crops. Vegetable grafting has been especially common in countries such as Korea, Mexico, Japan. While tomato grafting in particular is a fairly new concept in the US, it’s becoming more popular especially in Northeastern and Southeastern parts of the US.

Grafting is the practice of connecting two or more plants together to grow as a single plant, which consists of scion (top part of the plant, which produces the branches, leaves, flowers, and fruit) and rootstock (lower part of the plant, which produces the root system). For our workshop, we used Black Krim and Brandywine as scion. Rootstock should be chosen for its vigor, disease resistance, etc. and Maxifort is a very popular rootstock. However, as it was out of stock we used Emperador this time.

All the attendees practiced grafting. The grafted plants were then transported to the healing chamber that Jason Jones at The Homestead had prepared. Grafted tomato plants have to stay in the moist chamber with no light for four nights.

Some key tips to remember when grafting:

●Make sure plants are not water or nutrient stressed, but do NOT water the day you plan to graft because the water pressure will push the graft union apart.

●Have a clean working area

●Disinfect hands, tools, and grafting clips.

●Graft indoors (cloudy day or late afternoon is the best time)

●Be close to healing chamber, have healing chamber construct BEFORE grafting

●Get plants ready side by side- make sure you label clearly

The participants took home some seeds and clips to try grafting on their own. PFI will be in touch with them to record the success rates and collect feedback from their experiences to possibly design a larger scale research on tomato grafting as part of PFI cooperators’ program in 2013.

Mechanics of a Diversified Farm Field Day

October 4th, 2011 @ 8:53 am by Sally

Eric and Ann Franzenburg opened their farm up to 60 friends Sunday, September 18. They discussed how they have diversified to increase profitability and create a resilient farm. Read more about their operation in last winter’s newsletter here.

The rain kept people from the Regi obstacle course Eric had set up in the field, but didn’t keep people from learning about their high tunnel, greenhouses, machinery, and GAP certification.

Eric Nordschow from Windridge Implements brought some additional machinery to demonstrate some options available for specialty crop farmers.

Here are a few notes from the field day:

Eric and Ann have insulated their side by side greenhouses underground to hold in heat that is introduced subsoil through water lines. Read more about their system here. They use a corn boiler to provide heat to the greenhouse. When the system was installed, corn was selling for $3.50/bushel. This year it will likely sell for almost $7/bushel. Add the sweat equity is requires to fill the boiler daily, and Eric is not convinced that corn is the most efficient or cost-effective product to use in his system: “Industry is just starting to explore alternative energy options. Hopefully we will see some good innovations.” When Eric visited the manufacture of his boiler, Year-a-Round Corporation, in Mankato, MN, they were burning chipped tires in their heaters. He is interested in seeing more energy-dense crops pelletized for use in his corn boiler.

I sat in on the GAP discussion, so missed the machinery discussion. If you want to know more about farm machinery shown in these photos, you’ll have to ask Eric Franzenburg, Eric Nordschow from Windridge Implements, or any of the other folks shown in the pictures.

Ann discussed the process they went through last fall to become GAP (Good Agricultural Practices) certified. She summarized some pros and cons of the process:

Pros:

  • It helps you assess your food safety plan and procedures.
  • It formalizes training for employees and family.
  • It makes you think carefully about why you do what you do.
  • It holds you accountable for the products you introduce into the market.
  • It creates a simple way to track items in case of a recall.

Cons:

  • It is expensive: the farm has to pay for the certifier to make at least two farm visits a year including travel, and there are no certifiers in Iowa currently.
  • The process is currently set up to certify by crop. Ann and Eric only got certified for grape tomatoes. Certifiers need to see the actual harvest of each crop to be certified, and have a GAP plan for each. This is laborious and expensive.
  • The new USDA Food Safety Modernization Act requires farms to have written food safety plans. The Tester Amendment exempts farms with less than $500,000 in revenue from this requirement. However, some aggregators and wholesalers are requiring GAP certification for all producers who sell to them.
  • Requirement discrepancies between certifiers: USDA requirements differ from Primus requirements, a certifier currently working with some Iowa businesses. This is causing minor confusion and differences in food safety plans.

Ann and Eric are not going to re-certify next year because their markets don’t currently require GAP certification. Ann does feel she learned a lot of practical lessons during the process, and has an implementable food safety plan the farm will continue to utilize.

Different entities in Iowa are working to getting GAP requirements more in line with small producers. For instance, they are working on whole farm certification rather than a per crop certification. They are working to change the requirement to see each crop harvested to crop families (i.e. bunching greens, roots, etc.). They are also training people in Iowa to be GAP auditors, so farms won’t have to pay for an out of state certification visit. Some of these changes to improve the certification process may have already taken place.

Ann recommends all farms create and adopt a food safety plan. Here is her plan, as well some of her farm logs. She adapted these from a template she received from USDA.

Here is a link to blank templates:

Food Safety Plan Templates

Ann shared a few tips for recordkeeping components of the plan:

  • Don’t put it in the plan, unless you want to do it (if the plan says you will clean the bathroom daily, and you end up cleaning it twice a week, you will not be complying with your plan).
  • Only report what you’ve done. Don’t check off future activities (again with the bathroom: “I know I clean the bathroom every Wednesday, so I’ll go ahead and check all Wednesdays for October.”
  • If you use examples from the template, tweak them to conform to the realities of your farm.

The field day wrapped up with a wonderful local dinner. Ann and Eric’s daughter Ellen crafted some delicious peanut butter bars for dessert. She promised to share the recipe, so if you were there and want it, send me an email!

Field Day Report: Juan O’Sullivan’s Secrets to Successful Salsa

August 10th, 2011 @ 4:06 pm by Sally

On August 3 approximately 80 people visited Sean and Becki Sullivan’s business near Cumming to learn their secrets to expanding their love for making salsa into a profitable business. Sean started off asking people, “What’s your lightning in a bottle? What differentiates your product from all others out there?” For Juan O’Sullivans, one of their trademarks is their chile roaster, and the fresh waft of goodness it creates weekly at the Des Moines downtown farmer’s market. Plus, according to Sean, their product tastes different than any in the world.

Sean attempted to get into Hy-Vee for some time, and each time he tried, the gentleman told him he already had plenty of salsa. Finally, Hy-Vee’s buyer acquiesced, likely so Sean would stop “bothering” him. Sean showed up to the initial sales meeting with a jar of salsa and a bag of chips, and selling his salsa and getting it into Hy-Vee stores with that single meeting.

Juan O’Sullivan’s is now sold not to individual Hy-Vee stores, but through their distributor, and rests on shelves in over 35 Hy-Vee stores. Their salsa is also available in six Dahl’s outlets, online, and weekly at the Des Moines Farmer’s Market.

Sean applied for a Value-Added Producer’s Grant to help ramp up his business. This opportunity allowed him to fund scaling up personnel, infrastructure, and marketing, with the idea that the business will have stable enough legs to be viable without financial assistance once the grant period is over. Business sustainability looks promising for this central Iowa salsa business.

Kate Sand from USDA attended the field day to discuss opportunities the Value-Added Producer Grant provides to growers and grower cooperatives. Both planning and working capital grants are available, but the deadline to apply, August 29, is fast approaching. Sean utilized a grant writer to assist in preparing for the grant, and he recommended others without this skill set consider doing so; the process could be considered labor-intensive.

John Whitson of Sunrise Gardens and Sean led a tour of chile gardens on Sean and Becki’s property. Due to the extreme heat of July, including warm nights, the peppers were lacking in size and flowers. However, with the break in heat and cooler nights we have experienced since the event, those pepper plants are likely rejuvenated. Sean and John provided these tips for growing peppers:

10 Quick Pepper Gardening Tips From Juan’s

Planning: If you are starting plants from seed, buy the seed in January from reliable sources to avoid shortages and back orders. Plant Peppers 8 weeks and Tomatoes 6 weeks before target garden planting dates (Midwest Zone 5 is May 5-10 for Tomatoes and May 15-20 for Peppers).

Composting: All season long, put everything you can in the garden for fall or spring tilling; grass clippings, compost, fine wood chips etc… the more material you can get in the garden the better.

Soil Testing: Be sure to have your soil tested through your local Extension Service or Ag University. Knowledge is our best tool to success in the garden.

Patience: Don’t try to plant too early.  If you buy bigger, older, more expensive plants and get them in the garden a couple of weeks early, not only do you risk weather damage but even if everything goes well, you may harvest a pepper or a tomato only a few days earlier than plants planted under normal procedure.

Variety Choices: Know what you are going to do with your produce. What will you cook, where will you sell it or give it away and what does your target market want to use and eat? Choose varieties that make sense. Do you need peppers for sauce or salsa? Big difference.

Irrigation: Peppers especially do very well with consistent water and under conditions where the plants are not subject to fungus / virus infected soil splashing up on them with the rain. Using drip tape and plastic puts your plants in a controlled and more likely to be successful environment, especially in a dry year.

Spacing While Planting / Mapping: Space your plants with easy harvesting and growing environment in mind. Don’t try to put too many plants in your space, or you may pay a price with no/low production. Pepper plants need to breath, especially in a wet year. I recommend spacing plants over two plus feet apart in the row and double rows at least five plus feet apart.

Varmints: Varmints , especially rabbits, love to eat tender young pepper seedlings. Chicken wire at least two feet tall works best. Take the fence down and save it for next year, after the plants are a foot tall or so.

Newspaper and Straw: In a smaller non-irrigated environment, you may want to use newspaper and straw to keep weeds out, moisture in the soil and fungus infected soil from splashing on your plants. After your plants are a foot tall and really growing well, weed the garden, lay two sheets of newspaper everywhere and put a light layer of compost, straw, hay, mulch, really anything to hold the newspaper down. Wet the job with water to keep it in place until it rains. Till the newspaper and straw right in the soil in the fall or spring. This works!

Pick Early and Often: Peppers proliferate and rebloom if managed with early picking. Pick a few of the small peppers off of your plants while still immature to allow the plants to get bigger and framier, and promote new blooming on the plant. You may double your per plant production.

Juan grows chiles at his home, but these only provide a small portion of the peppers that go into the approximately 940 pounds of salsa bottled each week in their kitchen. Sean subcontracts with John Whitson and a handful of other growers and purchases all the peppers they are able to grow. He likes that chiles and garlic he purchases from other Iowa growers are spread across farms- it mitigates risk of crop failure. John also imports chiles from New Mexico to fill in supply gaps.

Becki and full-time employee Thomas Burkhead led a tour of Juan’s certified kitchen where their product is prepared and bottled. They overviewed basic design requirements to be able to certify a kitchen, including: washable surfaces, access to a bathroom, separate sink for handwashing, proper ventilation, and that the kitchen be able to be closed off from the rest of Sean and Becki’s home. Becki and Thomas would seal off the kitchen regardless of this regulation, because failure to do so leads to everything, including clothes in closets, smelling like salsa.

Sean and Becki have provided an ingredient list and their salsa-making process to regulators, and have the ingredient-list stated on their label. They measure the pH of each batch to ensure there is a level of acid present to create a shelf stable product. After Becki and Thomas chop, mix, and cook the product, they hot pack the items, so this acid level is crucial.

Linda Naeve from ISU Value-Added Extension, a sponsor for this field day, highlighted some of the services Value-Added Extension provides. She also overviewed MarketMaker, a tool that connects producers and buyers.

The conversation was wonderful and attendance great, so these things were on the agenda and didn’t get as much attention as planned: preparing value-added for products for sale in retail stores and branding. I was excited to participate and listen in on Sean’s creative branding exercise, so hopefully we can recreate this in a future event.

The event ended with some magnificent roasted green chile served on pork sandwiches, chips and sauces (of course), watermelon, green bean salad and carrot slaw. Sean conducted a roasted chile demonstration, proving these a worthy “lightning in a bottle.”
