Planting Day at the Fond du Lac Biochar Demonstration Garden

The CenUSA Bioenergy biochar demonstration gardens are now about to embark on year two of the CenUSA Bioenergy project.  This year, the University of Minnesota is adding the Fond du Lac Biochar Demonstration Garden in Brookston, MN to its list of biochar demonstration garden sites.

Julie explains the CenUSA Bioenergy biochar demonstration garden is  1000 sq ft and is divided into three plots of 300 sq ft each. Each plot has different amounts of biochar that have been added (or not added), as outlined here:

  • a Control (CTRL) plot with no biochar added;
  • a Treatment 1 (TRT1) plot amended with one-half pound of biochar per square foot (150 pounds), and a
  • Treatment 2 plot (TRT2) amended with one pound of biochar per square foot (300 pounds).

We used soil test recommendations from the UMN soil test report and applied a nitrogen fertilizer and murate of potash to all plots.  This fertilizer will provide the nitrogen and potassium needed to grow plants in the 1000 square foot Fond du Lac Demonstration Garden soils.

Exploring our Roots – A Short History of Extension and the Master Gardener Program

(Editor’s note: Exploring our Roots is an excerpt first written by Bob Kellam for the North Carolina Extension Master Gardeners Volunteer Association Newsletter.  His preface is directed at members of the North Carolina Extension Master Gardener Association, but has relevance for all programs exploring the roots and connections between Extension and the Master Gardener program.}

Preface:  Those of you who attended last year’s conference in Asheville may remember the lively discussion we had at the membership meeting concerning the addition of “Extension” to the Association’s name.  I was struck by the number of Master Gardeners who wondered aloud why we would want to do that.  What does Extension have to do with the Master Gardeners anyway?  It occurred to me that, beyond the fact that our program is part of Cooperative Extension, my own understanding of how and why Extension came to be was sadly lacking.  So I set out to do some research on the subject.  The results of that effort are below, albeit a bit condensed.  Some of the questions I set out to answer were:  Where did the name Cooperative Extension come from and why do you usually get blank stares when you mention it?, Who was the first Extension agent?, What was the real reason for creating 4H?  and, Where does the EMG program fit in?  I hope you will find the answers as interesting and illuminating as I did. – Bob

The Beginning: Industrial Revolution Brings Progress, Agriculture Struggles

It wasn’t so long ago that about half the U.S. population lived on farms.  Now only about 2% of us do, and only 17% live in what are called “rural areas”.  80 years ago, most of us would have been very familiar with the work of Extension. Now only about 1 in 5 would recognize the name.  And therein lies the rub: Extension has never been just about agriculture, but even most of the 20% would say: “oh, yeah, that’s 4H and the ag agents.”

In the latter part of the 19th century, the industrial revolution is well underway and the cities are growing, but half of us still live on farms, and it has become, for the most part, a hardscrabble life.  Agriculture in America is an unproductive system, built on tradition, superstition, and backbreaking toil.  Families spend as much as 40% of their income on food, and the disparity between the quality of life on the farm and life in the city is getting larger, with a considerable proportion of the former suffering from poverty and illiteracy.  Most farmers are suspicious of the new techniques being developed by the fledgling USDA, referring to them as “book farming.”  As a result, productivity is down, soils are being depleted in as few as 5 years, and food prices are going up.  Something has to give.

Morrill Act Forms USDA and Land Grant Universities

Early in President Lincoln’s first term, Congress finally gets its act together, despite the fact that there’s a war on, passing in the same year the “Organic Act” which formed USDA and the Morrill Act of 1862.

The Morrill Act establishes “Land Grant” universities in each State to educate citizens in agriculture, home economics, mechanical arts, and other practical professions.

NCSU
In the first year as a land grant university (1889), NCSU boasts 72 students and 6 faculty.

The idea of a “land grant” is actually a practice we borrowed from Europe, in which the government provides a grant of federal land to be used for a specific purpose, or which can be sold to raise funds for that purpose.  In this case, the specific purpose is considerably different from the liberal arts curricula of most institutions of higher learning.  The implementation of the law leads to the formation of the North Carolina College of Agriculture and Mechanical Arts in 1887 and it’s first class matriculates in 1889.

Hatch Act Creates Agricultural Experimental Stations

'Father of Extension'?
Seaman Knapp

In 1867, the Hatch Act creates agricultural experimental stations and, in 1890, the second Morrill Act, aimed at the former Confederate states, provides additional funds, but with a catch: the states must demonstrate that race is not a criterion for admission.  In those separate but not so equal times, this leads to the founding of our second land grant university, NCA&T.  But the USDA, charged with raising productivity and bringing down the cost of food, is still grappling with how to get farmers to embrace the new practices being developed.

Enter one Seaman A. Knapp, felt by many to be the father of Extension.  He is a physician by training, a college instructor, and comes to farming late, but is impressed by the new farming techniques being developed in Michigan and Iowa.  In 1902, he’s dispatched to Texas to start a demonstration farm to help combat the cotton boll weevil.  The farm is a successful cooperative venture with local farmers and the idea quickly spreads across the South.

In 1907, the USDA sends Cassius R Hudson to North Carolina to start a similar demonstration program.  Unfortunately, he isn’t received all that warmly by the local farmers who view him as just another Washington bureaucrat who is out of touch with “real agriculture.”

Cassius Hudson

Under the rules of his employment he must be paid by the State, and the only federal support he is given is $1.00 for mailing expenses.  North Carolina grudgingly assigns him office space adjacent to the area where the corn and grain exhibit for the state fair is stored, and numerous, well-fed families of mice from next door visit regularly, much to the distress of the secretaries.

Clubs promote growing and food preservation practices

In 1908, to promote some of the new growing practices, NC State signs a memorandum of understanding with USDA to start Farmers Boys’ Clubs, the forerunner of 4H.  The success of the resulting “Corn Clubs” is still being celebrated 50 years later.  In 1911, Jane S McKimmon is hired to develop girls’ “Canning Clubs” and “Tomato Clubs” in response to an epidemic of food poisoning, due in large part to poor food preservation practices.  This focus on youth is largely motivated by the USDA’s repeated failure to persuade older farmers to adopt better practices.  USDA begins to realize that raising a new generation of farmers more open to improved techniques may be part of the solution.  And the strategy pays off.

Smith Lever Act Extends Practical Applications of Research to Counties

The growing success (literally) of these programs leads to the passage in 1914 of the Smith-Lever Act, also known as the Extension Agriculture Act. Smith-Lever is designed “to aid in diffusing among the people of the United States, useful and practical information on subjects relating to agriculture and home economics, and to encourage the application of the same.”  The Act forms a partnership between the USDA and the land grant universities to extend the practical applications of research through demonstrations at the county level (e.g. your cooperative extension office), and requires the states to match federal funding on an equal basis.

Smith-Lever is still considered one of the most responsible and ingenious pieces of legislation ever passed by Congress.  It provides the authorizing legislation to create an Extension presence at the county level and does so by shared funding with state and local governments.

Father of Extension?
Squanto, the 1st Extension agent?

There is some dispute about who should be recognized as being the first Extension agent.  Seaman Knapp, of boll weevil fame, is one contender.  But another popular candidate, given the mission of Extension, is Squanto, a member of the Patuxent tribe who, legend has it, helped the Plymouth colonists through their first hard winter in 1621, by teaching them how to grow corn by adding a fish for fertilizer.

Core Principles of Extension Revealed Through Acts

The things that the implementers of the Morrill, Hatch, and Smith-Lever Acts learned in translating these laws into effective programs can be distilled down to a simple statement:

If you want to persuade people to undertake something, the effort needs to be: responsive to a recognized need or issue; cooperative and interactive; practical, well-demonstrated, and service-oriented.  Throw in un-biased, research-based information and include a focus on youth, and you pretty much have the core principles of Extension – and the Extension Master Gardeners.

Extension During the Farm and Great Depression

Over the next several decades, there are several more forces that help to shape Extension.  In the Farm Depression of the 1920’s the focus changes from production to economic concerns and quality of life issues.  Extension’s ranks thin, emergency funds disappear and the program become more dependent on volunteers.  This has the positive benefit of stimulating rural leadership, however, as well as the formation of local cooperatives.

The next major test is the Great Depression and the Dust Bowl of the 1930’s.  Extension draws farm families into county, state, and national public affairs.  Home economic programs focus on self-sufficiency.  Ultimately, Extension is called on to manage several new agencies: initially the Farm Seed and Loan program and, later, the Soil and Water Conservation Service, Agricultural Adjustment Act, Rural Electrification, and Federal Housing Administration.

Volunteers Become Extension Backbone After World Wars

During and after the World Wars, Extension helps the country focus on food and fiber production for the war effort and volunteer leadership evolves.  It is during this time that volunteers become the backbone of Extension.

WSU Forms the First Extension Master Gardener Program

In 1972, the Washington State Cooperative Extension, in response to a high demand for urban horticulture and gardening advice, forms the first Master Gardener program.  By the end of the decade, the program has spread across the country to North Carolina.  New Hanover county gets bragging rights for creating the first gardening hotline in 1979, but Wake County, NC graduates the first class of Master Gardeners in the same year.  By the 2009 survey, there are more than 95,000 Master Gardeners nationwide, providing 5,000,000 hours of volunteer service annually.

So, How Does the Master Gardener Program Align with Extension?

One of the questions I had posed for myself when I began this research was: where does the Master Gardener program fit in to Extension? The answer I’ve come to understand is: just about everywhere.If you line the Master Gardener programs up against the core principles of Extension the match is clear:

  • We respond to the recognized needs of waterwise strategies, avoiding invasive species, and minimizing fertilizer and pesticide use.
  • We provide cooperative and interactive phone and email support, successful gardening clinics, speakers’ bureaus, farmers’ market assistance, and junior Master Gardener training.
  • We offer practical help in best gardening practices and teaching courses like Vegetables 101.
  • And we are service-oriented through our community gardening, Habitat for Humanity, and horticultural therapy programs.

Cooperative Extension Programs –  Yesterday and Today

And, should you be tempted to subscribe to the notion that Extension has somehow become less relevant as America has become less rural, consider the kinds of programs that Cooperative Extension currently offers to counties.

In Community and Economic Development, Extension offers municipal official development, rural-urban interface studies, land use issues, public policy, and water quality programs.  For families and youth, there are programs on health and food safety, managing family and household resources, strengthening family life, volunteer and leadership development, and improving the life skills of youth. In agriculture and natural resources, Extension manages programs in plant and animal science, fruits and vegetables, turf and gardening, farm management, forestry and forestry products, and marketing agricultural products.

It would appear that Extension’s responsibilities have broadened over the years.  If you focus on what Smith-Lever wanted to happen in the area of food production: greater reliance on research; higher and more efficient production; and cheaper food, you might argue that we have succeeded too well.  As far as the goals for its second century, we do have some hints: promoting local food (the current flagship program in NC), encouraging sustainable production (not depleting our resources faster than we can replenish them), and, at least, recognizing the potential adverse impacts of some of the research inroads we’ve made in the last few decades (pesticide and hormone residues, GMO, mono-cropping, and the narrowing of the gene pool.

Strong Belief in Equality of Individuals, Possibility of Change and Progress, Reliability of Scientific Information, Power of Education

If we focus on the underlying principle of Extension as improving the quality of American life, then the periodic adjustment and re-calibration of our goals is wholly consistent with a research-based organization.  And, throughout its history, the guiding philosophy of Extension has remained unchanged: a strong belief in the equality of individuals, the possibility of change and progress, the reliability of scientific information, and the power of education.

Liberty Hyde Bailey, another of Extension’s founders was a member of the Cornell faculty and dean of the New York College of Agriculture from 1903-13.  He observed:

  “Extension work is not exhortation.  Nor is it exploitation of the people, or advertising of an institution, or publicity work for securing students.  It is a plain, earnest, and continuous effort to meet the needs of the people on their own farms and in their localities.”

And, since he was a teacher, he had the habit of asking his students: “What do you know today that you did not know the last time we met?”

 

2012 The University of Minnesota Biochar Test Gardens and Challenges (Part 4)

 

In my last few posts, I’ve described how University of Minnesota Extension Master Gardeners have been involved with the 2012 biochar test gardens with the CenUSA Bioenergy project.  As you’ll see throughout this post, from planting to data collection, we met some challenges with germination, weeds, insects and plant diseases in 2012.

2012- Plans and Design for CenUSA Bioenergy Biochar Test Gardens

What did we decide to grow?

Plants for Biochar Test Gardens
Plants for Biochar Test Gardens

Each site was designed to include basic plants that typical homeowners would grow such as annuals, perennials, vegetables and herbs. The design was laid out with short annual plants in the front and perennials near the back.

Edible crops that were grown included: green beans, tomatoes, green and hot peppers, Swiss chard, leafy kale, cucumbers, lettuce, asparagus, potatoes, and basil.

Ornamental crops included zinnias, petunias, marigolds, MN hardy mums and Ole, Lena and Sven hardy shrub roses.

First Year Test Garden Challenges

Seed and Shade Challenge

Early on we had some germination issues with the beans. Two of the three teams opted to replant, but by the time the second planting germinated, the Swiss chard was so large it shadowed the bean row too much…so no beans.

The potatoes were also spotty. The potato sets were mailed too early from the company we purchased from and even though they were kept under refrigeration, they got moldy and their germination was poor as well.

Pest Challenges: Aster Yellows, Japanese Beetles, and Weeds

Other challenges in the gardens included weeds, Japanese Beetles in two of the tree sites, more weeds, aster yellows disease on marigolds and petunias…and did I mention weeds?

The captioned photograph to the left shows a marigold infected with Aster yellows next to a healthy marigold (however it didn’t stay healthy very long) and embraced by purslane.

What to do with Poison Ivy in Andover?

The Andover site as I mentioned, was filled with small trees and underbrush including poison ivy – that also became a challenge to deal with.  However, the Master Gardeners did a great job of keeping it under control by using herbicides only around the exterior perimeter of the garden and hand pulling any sprouts that came up in the garden.

A couple of volunteers were nervous about eating produce that may have poison ivy roots coming into contact with the vegetable roots. Upon researching this concern with the Minnesota Department of Health, they felt the risk was low, but if the poison ivy roots came into contact with root vegetables like the potatoes, it was cautioned to peel the vegetables first.

I then went a little further in my research and learned that the famous naturalist, Euell Gibbons, used to recommend eating poison ivy leaves – just a little a day, to build up a tolerance to the urushiol (the toxins in the poison ivy). I then noticed someone had blogged that they tried that and the only side effect they experienced was a little itchiness in their behind after the poison ivy passed through. YIKES!

End of Season Differences in the 2010 Biochar Test Garden

Comparing Lettuce Between Sites – Difficult Since Japanese Beetles Got Dibb

The lettuce, the earliest season crop, was harvested first. However, the Japanese beetles had such voracious appetites in the St. Paul Campus garden that less than 50% of the plants were left to weigh. The Japanese beetles hit the Arboretum site too, but not as badly. Japanese beetles haven’t found Andover yet (which is farther north than the other two sites), but they have been spotted less than six miles from that test site.  I have a feeling we may see them in 2013.

The gardens did get a little over crowded especially in the nutrient rich St. Paul Campus and Arboretum sites. To ease some of that, the Swiss chard was harvested early which allowed for more room for the kale and other vegetables. I will talk a little more about the harvest under “Collecting Data”.

Differences in Garden Vigor?

Overall the gardens at the St. Paul Campus and the Arboretum have the most vigor. It would be safe to guess that is because the soil was so much better, plus the added nitrogen resulted in heavy plant growth. In Andover, there appeared to be a lot of nutrient deficiency, not surprising considering it is very sandy soil and the 10-10-10 fertilizer,applied only once in the spring and had leeched through the soil early in the season.

Interestingly though, there was a noticeable difference on kale size between the control plots and the biochar treated plots. I believe that may be because of the moisture and/or nutrient holding capabilities of biochar in the poorer soils. However, it will be tough to gain analysis between treatment one and treatment two, because treatment two also has morning shade, which also contributes to the moisture not evaporating as quickly, and it also didn’t suffer from heat stress as much as the other two plots.

Collecting Data Will Lead to a More Comprehensive Report Soon!

Most of the data that we wanted to collect had to do with growth and yields. Weights and counts were collected on produce such as potatoes, cucumbers and tomatoes, plus plant heights, widths, stem strength, bloom production, etc. were also monitored on all of the plants. A comprehensive report with all of the results will be coming soon.

As we prepare for 2013, we are now putting together what we learned from the 2012 growing season so we can improve data collection and improve our research with the  CenUSA Bioenergy project for 2013.

From here on forward, stay tuned, as we begin to blog about our 2013 season as it happens this year!
