GM Alfalfa: Changing the Future of Dairy and Organic Farming?

With “World Food Day” approaching - October 16th - I thought it was timely to bring up some of the more ‘global’ issues reaching our ‘local’ food systems.

Let’s explore what COWS, BEES, and MONSANTO have in common.

The answer is ALFALFA!

Some may be thinking, so what? I don’t eat much alfalfa myself. But, if you eat chicken eggs, cheese, ice cream, or cows, you do eat alfalfa. Alfalfa is used as cow and chicken feed. In fact, it is the backbone of the dairy industry. Alfalfa also creates its own natural fertilizer. It captures nitrogen from the atmosphere and makes it available in the soil. This makes alfalfa a key resource for organic farmers who do not use chemical fertilizers.

Alfalfa Hay
The dairy industry, and organic farming in general, is about to change drastically with the proliferation of genetically modified alfalfa, aka GM alfalfa. GM alfalfa seed is the project of a multinational company, Monsanto. GM alfalfa was once banned in the USA, but courts have recently overturned this ban. GM alfalfa is not yet legal in Canada, but a quick Google search, or conversation with a Canadian farmer, will reveal that the pressure is on. 

We know the links between dairy, Monsanto and alfalfa, now where do bees fit in this equation?

Bees pollinate alfalfa. Once a GM bee-pollinated crop is let loose there is no turning back (recent history tells this story for GM canola). Bees go everywhere; therefore, so does the pollen they collect and exchange among distant plants. An exchange of pollen from a GM plant to a non-GM plant can result in the exchange of genetic material. Successful exchange of genes means that the seeds of a new plant generation in the non-GM fields may be genetically modified (aka “genetic contamination”). Because bee pollinated crops are at high risks of genetic contamination, even farmers who want to avoid these GM plants often can’t. For certified organic farmers, the introduction of GM alfalfa is particularly alarming.  As you may know, organic certification prohibits the use of genetically modified seeds. Therefore, farmers that rely on non-GM alfalfa can run the risk of losing their certification if they are found with GM plants in their farms.  


Organic Alfalfa Put To Use!


What is GM Alfalfa?

Like other Monsanto-modified seeds, such as soy or canola, GM alfalfa is genetically altered to be resistant to a broad-spectrum herbicide. This herbicide called “Roundup” – also produced by Monsanto - is marketed because of its chemical capacity to kill weeds. “Roundup Ready” crops can be sprayed with the herbicide Roundup to support industrial-scale crop production (on the short-term). Although GM crops are resistant to herbicides, components of such herbicides (e.g., glycophosphates) can affect other life forms, such as aquatic organisms, as well as soil system complexes. 

Canadian farmers I’ve spoken to see no reason for GM alfalfa. They also view Monsanto as the only beneficiary. First, this company will benefit because the use of their seeds goes hand in hand with the use of their Roundup chemicals. Second, Monsanto holds the patent, thus the legal rights to control the GM seeds (and the herbicide-resistant genes for that matter). Therefore, once crops become contaminated with GM genes, farmers are no longer owners of their crops. This prevents farmers from saving-seeds after harvests, and implies the need to purchase new seeds from companies each year. The implications of this cannot be overstated. For millennia farmers have saved and traded seed maintaining natural sources of diversity. In the words of Bartlett and Steele, “Monsanto has turned this ancient practice on its head.”

One farmer I spoke to sees a benefit in GM crops.  This Manitoban said that his “Certified Local Sustainable” bee farm is stuck in a sea of crop monocultures frequently sprayed with pesticides. In his opinion, GM crops have resulted in less frequent spraying of herbicides because GM crops have a high level of pest resistance. He said that less spraying has resulted in his bees picking up fewer chemicals. We ended our discussion on the note that more attention to GM crops is needed, especially because the human experience with GM crops is extremely limited.

This begs the question, why are we modifying crops in the first place? Or similarly, why are we growing so much of the same thing?

Being that there is strong political and economic support for seed modification, I am curious what support exists for those that explore alternatives to GM seeds. If you weren’t sure how to contribute on “World Food Day”, here is an issue we can talk about. If anyone has any GM crop-related comments, please feel free to post them here, or to e-mail me.

Also, in light of World Food Day, I hope to post a few short posts related to unique projects seeking alternatives to industrial food production. Any ideas? Send them my way!

Meet Your Farmer



In many posts, I’ve suggested that the best way to find out just where your food comes from is to talk to the farmer that produces it. The opportunity for me to do just that arose recently during “Open Farms Day”. To encourage farming and food education, the province of Manitoba organized this event, which included around 40 open houses at participating farms. To take advantage of this opportunity, I took a 45 minute drive and spent some time on the Blue Lagoon, certified organic farm. Here are a few highlights.

My visit began with a walk through a chicken coop. The chickens barely noticed me, they were busy pecking at melon rinds outside of their coop. I couldn’t help but ask, don’t chickens eat grain? Sure, replied Stefan, a farmer and Manitoban chef. He explained that the chickens are happy to eat parts of their food compost, and they especially love fruit seeds. Stefan continued to explain that the melon rinds were left over from his gelato experiment.  In fact, Stefan explained that the chickens are great composters, they work food remains into the ground as they peck and graze. This year Blue Lagoon has not used any mechanical tilling of the soil. Instead, chickens are moved around to different soil patches. Just letting the chickens roam around can help transform the soil from hard unworkable land to aerated and more fertile ground.


Next, I hopped on a wagon towed by a tractor and was greeted by Stefan’s parents, Lori Ann and Rene. Clearly proud of their farm, which was recently certified as organic (the only one in St. François Xavier), they explained how every patch of land has its purpose. In the fields you could find rows of veggies, each row a different species, and within rows different varieties. Less fertile land was filled with alfalfa plants. Alfalfa breaks up hard soil and also provides a natural source of nitrogen. It looked perfect if you ask me. But, as Lori Ann soon pointed out, things weren't as simple as they looked. She drew our attention to the live raccoon traps within the fields, as well as garbage bag flags used to deter hungry mammals. Some of their most common visitors are deer. Deer are especially fond of their organic strawberries. So much so these farmers confessed to have forfeited their strawberry crops over the past few years to curious and hungry deer.  

Because these flags are always moving, they are thought to simulate predators and discourage crop thieves
I inquired if animal thieves and crop pests present the greatest challenge for organic farmers. In response I was informed this was partly right, along with the challenge of maintaining soil fertility without chemical inputs. Lori Ann pointed out their cauliflower plants whose leaves had been chewed on by insects. In fact, there are only two things organic farmers can use as insect deterrents while retaining their certification. One is Btk, a bacteria thought non-toxic to organisms with the exception of some insects. The second is row cover, a cloth used to cover plants. Although Btk is an option, Blue Lagoon rarely uses it. They prefer to keep things as natural as possible. 
Cauliflower Plants

I was surprised to later find out that the only insect ‘pest’ this year had been the crucifer beetle, it was this insect that had caused the cabbage damage I noticed earlier. At the end of the tour, Stefan convincingly explained how their farm doesn’t actually have that many pests simply because they don’t grow too much of one thing.  Because this farm is surrounded by a matrix of canola monocultures, it was no coincidence that the crucifer beetle found them. Crucifer beetles eat cruciferous plants, which include crops such as cauliflower or canola. The beetles thrive on monoculture farms, such as the ever-expansive prairie canola fields. A vast crop of the same species is also a concentrated food resource for pests. In addition, because monocultures simplify the complex landscape, this means monocultures have less natural enemies around to control thriving pests. This is a clear example of the far-reaching impacts of industrial agriculture, even organic farmers can’t avoid them.

In previous posts, I’ve discussed the pros and cons of organic certification and the benefits of supporting farmers who aren’t officially certified but practice organic, or nearly organic, farming. I thought I would get an expert’s opinion on these subjects. Lori Ann enthusiastically responded that she sees a strong benefit in purchasing food that is certified as organic, as well as being an organic-certified farmer herself.  I smiled as she said, “this ensures that us farmers don’t cheat!” She explained how hard it is to watch as your crops are destroyed and not be able to do anything about it, no matter how tempting it may be to use something like chemical sprays. The threat of losing the organic certification is a big motivation in holding off on the chemicals.

I’ll leave the choice to support certified organic, or other sustainable practices to the readers. What I do recommend is a farm visit or a conversation with a farmer at any chance you get. Thanks again to Stefan, Lori Ann, and Rene for sharing their time and experiences as organic farmers.
