Why I’m Not An Organic Farmer

Pesticides, GMOs, Roundup, super-weeds, evil wheat, big Ag and a hundred other buzz-words are touted as the failure of modern agriculture’s quest to feed the world.  Organic farming is proclaimed as the solution to these problems, as the future of sustainable agriculture. The reality is, as I will tell you in this post, that the opposite is true; conventional farming, not organic, is better for the environment and can sustainably and safely feed a growing world.

As an aside, I have no problem with most organic farmers. The ones that I know do it not for idealogical reasons, but for economical ones. For their farms, they believe they will make more money growing organic crops than conventional ones. There is nothing wrong with that, and I don’t want to go on an attack against farmers doing the best they can to do what they love. Furthermore, I’m not going to go on record saying that conventional agriculture is perfect. We have many improvements to make, and there are some real issues that need to be addressed – but that is a concern for another day. Also, for the purposes of this post, I want to focus in on crop production, so I’ll leave livestock out of this discussion.

Organic vs Conventional Agriculture: What’s The Difference?

First of all, I don’t want to assume everybody is as obsessed with agriculture as I am, so let’s just go through some basic differences between these two production methods.

Organic agriculture is a $2.6 billion dollar industry in Canada, with regulations stipulating what products farmers can use on their farms. Genetically modified crops are not allowed, and neither are synthetic fertilizers. Pesticides are a more complicated matter, with only “organic” chemicals allowed for use.

For a farm to be certified organic, each of its fields must be free of any prohibited substances for three years before certification by the Canadian Food Inspection Agency is allowed. Are organic crops tested before they are certified? No; at least, according to this source. The CFIA disagrees, but concedes it is still more or less an honour system.

Without synthetic fertilizers and chemicals, organic farmers must use alternatives to grow their crops and kill weeds and insects. Essentially, it is a reversion to agriculture practices of 100 years ago. While some of these practices are quite effective and perhaps even have a fit in conventional agriculture, most of them were abandoned years ago with the introduction of fertilizers and pesticides. The reasons were numerous, but they really all began in the infamous “Dirty 30’s”.

Tillage and Soil Erosion

Today, we talk about four elements of weed control: cultural (crop selection), chemical (herbicides), biological (using natural enemies- still a very new and undeveloped field) and mechanical. In modern agriculture, cultural and chemical controls are our primary weapons in the war against weeds, with the real emphasis on chemicals- crops like corn and soybeans are just not that competitive. Wheat, barley, canola and other such crops are actually very competitive, but they still depend on herbicides to get established and get ahead of the weeds.

A century ago, there were no real herbicides available. With that option stripped out, and biological controls in their infancy even today, that really only left mechanical and cultural controls- exactly like organic farming today. Mechanical control essentially involves steel; DSC_0367 (640x354)using shovels, discs, rods, harrows, etc. to uproot, rip and drag weeds apart to kill them. Every second year, each field must remain idle (not seeded, or “summerfallow”) and constantly tilled up to stay ahead of difficult weeds. This kind of intensive tillage leaves the ground bare, exposed to direct sunlight and the ravages of heavy winds. Remember hearing about dust storms? That is the unfortunate end result of old-school farming. Without chemical controls, there is simply no way to consistently grow crops (especially up here in the northern climates) all year round to stay ahead of weeds. Yes, natural grassland will do that, but how will that feed 7 billion people?

In my area of the world, I have seen- and continue to see- the effects of long-term tillage on our soils. Heavy rains and winds wash precious topsoil into ditches and sloughs. Wet spots in the field stay that way for months and months, allowing salts to collect on the soil surface; eventually turning the ground a ghostly white, a sober metaphor of the inability of that soil to grow anything again for generations. The reality is that, at least in Western Canada, herbicides are our only method of controlling soil erosion; they allow us to minimize tillage.

Is tillage the only way for organic farmers to control weeds? No; there are other methods, including cover crops and precise planting timing to keep weeds in check. However, as good as some of these methods can be, they are still not the solution, with most farmers opting for the reliability of tillage instead. And, ultimately, they still do not solve the other stark reality of organic agriculture: it cannot possibly feed the world.

A Growing Population Needs All The Tools It Can Get

In 1898, a scientist by the name of Sir William Crookes, new president for the British Academy of Sciences, stated unequivocally that the world would run out of food by the 1930’s. A lack of fertilizer would cause world crop yields to plummet, and massive starvation would ensue. Current production methods of manure and saltpeter harvesting to use as fertilizer would eventually be outstripped by an exploding human population. He said the only way to prevent this famine would be to synthetically produce fertilizer. Less than 20 years later that became a reality, thanks to Fritz Haber and Carl Bosch.

Our atmosphere is nearly 80% nitrogen. It is one of the most important building blocks of life; but it is unavailable to us – and plants – in its atmospheric form. Crops require nitrogen for growth and reproduction. Before synthetic fertilizer, animal manure and bird guano were the only sources of fertilizer. Crops were carefully rotated with nitrogen producing pulse crops and forages to generate as much N as possible. Yet, inexorably, yields would eventually decrease as the soil became exhausted of nutrients. The Haber-Bosch process solved that problem by converting atmospheric nitrogen to a usable form for plants. So, essentially, so-called “synthetic” fertilizer really isn’t synthetic at all; rather, it is a natural component of the air we breathe every day. Without it, the crop yields would long ago have failed, and the world would not be what it is today.

Without synthetic fertilizer, and their natural counterpart, pesticides, crops would not be able to sustain enough growth to feed the world as it is today. Haber and Bosch are responsible for one of the greatest inventions of our history. Why go back to the problems of 100 years ago when we have already found the answer?

Organic Food: Is It Really Healthier?

The final component of this blog post concerns the misconception that organic food is somehow more nutritious than conventionally grown food. There is a belief that pesticides somehow contaminate the seed of the plant itself, finding its way directly into our food. To some degree this is true. But the reality is that the residues that find their way into our food are so abysmally tiny that in 98% of our food, there is no difference between food that is grown conventionally and food that is grown organically. What about that other 2%? It still comes in below the stringent limits set by the government (source).

But wait; isn’t organic food healthier than conventional? According to a recent Stanford Medicine study, that is simply not true. No nutritional differences of significance were found when comparing the two production methods.

Organic Farming Is Not The Future

The answer to the question of whether organic agriculture is more sustainable, better for the environment or healthier than conventional agriculture is clear. Organic farming causes greater soil erosion, is not healthier or safer for consumption and would sentence billions of people to die, most of them in developing nations. Isn’t it easy to criticize a method of producing food when you have never been hungry?

I choose to farm with pesticides, GMOs and fertilizers because I know that it is the right choice. I know that standing behind the use of these products will help feed a growing and hungry world. Yes, there are still problems with our agriculture system, but I know that farmers and researchers are savvy and brilliant individuals that will solve these problems over time. Yes, organic farming is a choice some farmers make, and I am not going to attack their choices. What I am attacking is the marketing and smearing of conventional agriculture; the misinformation that permeates this discussion and diminishes the importance of it.

During my time as a farmer, I have spent a lot of time studying this issue. As an agronomist, I have seen first-hand the consequences of organic farming, and the successes of modern conventional agriculture. As a third-generation farmer, I know how amazing our progress has been in agriculture, and I am excited about the possibilities of the future.

Why I Grow GMOs

What do you think about GMOs?

Nikon J1 July (2) 160

Is there a more emotionally charged question out there in this part of today’s world? Certainly, it is understandable that the food we eat be an engaging issue for consumer and producer alike. There has been a drive from the consumer to learn about the food they eat. They want to know how it is produced, and whether it is in a sustainable fashion. Ultimately, and most importantly, they want to know if it is safe.  An unknown factor like genetic modification is a cause for concern for these people, because the long-term effects are not readily available to us.

I support and applaud those in the public that ask these critical questions. Too many people don’t think about the things that are done by the government, business and other organizations. The problem isn’t in people asking questions; it is in people asking the wrong questions to the wrong sources – and believing the answers without question.

I am a farmer that grows genetically modified (GM) crops. Not all of my crops are GMOs. In fact, in a usual rotation of 5-7 different crops, only two are GMOs. Canola and soybeans, two of my farm’s most economically important crops, are GMOs. Other crops, like wheat, peas and flax, are not GMOs, for there are simply none available. Contrary to popular belief, I do have a choice to buy GM crops or alternatives. So why do I grow GM crops when there are so many other cropping options?

That is a good question, and the answer will be different for every farm. In my life on the farm, canola and soybeans are our two newest crop options. In Western Canada, we have been growing wheat for as long as we’ve been farming. Flax and peas are old crops for us as well. Canola is one that we have really only been growing in earnest on our farm for the past 15 or so years. We only just started growing soybeans 3 years ago.

I suppose we could grow old open-pollinated canola and conventional soybeans (these are not GMOs). But would we do that? The claim I hear from some consumers is that GMOs are hazardous. By association then, I must be either cruel or naïve to grow these dangerous crops, putting other people at risk.

But here is the question I pose to the GMO haters: do you really believe I would grow these crops if I believed they were unsafe? My family eats the food we grow. I would not put them at risk if I truly believed GMOs were hazardous.

Honestly, I don’t believe they are. GM crops are not dangerous1. In the almost 20 years since Monsanto started genetically modifying corn, soybeans and canola, the evidence has become clear that the benefits of genetic modification far outweigh the risks1. This isn’t an opinion by a biased industry representative. The information I use comes directly from peer reviewed journal articles, the best source of information on anything scientific. GM crops also have dramatically reduced use of the most dangerous and volatile chemicals to control weeds2. Most of the GM plants we deal with are “Roundup Ready”, which means they are resistant to the active ingredient of Roundup, which is glyphosate. The way we measure the toxicity of chemicals like glyphosate is its LD50 number. This refers to the amount of the chemical, given all at once, which results in the death of 50% of the test animals3. The acute Low Acute Toxicity for oral consumption of glyphosate in rats is an LD50 value greater than 5,000 mg/kg of body weight4. This means that if you were a rat, and you weighed in at 3 kg, you would have to consume 15 grams of glyphosate for it to become toxic to you. That is quite a lot. Comparatively, the LD50 of caffeine is 192 mg/kg body weight. How much coffee do you have in a day? The point is, the dosage makes the poison, and any chemical can be toxic in a large enough dose.

Today’s farm operation is a complicated business. Every year, we run through the numbers on each crop to decide which ones to grow and on how many acres. Canola and soybeans, and especially canola, are profitable crop options for us. So yes, we do grow these GM crops because they allow our farm to make money. Are they making us rich? I wish! But they do allow our farm business to make enough money to survive, and hopefully, over time, prosper. Is this not the dream for us all?

Ultimately, the question of why I grow GMOs comes down to the fundamental freedom that we all have in our democratic society: the freedom of choice. It is my choice to grow GM crops. Conversely, if you don’t approve of them, it is your choice to buy something else. However, keep in mind the unintended consequences of doing so. GM crops allow us to use less toxic pesticides at lower rates. Furthermore, we can achieve unprecedented yields with the incredible biological advances made with these GM varieties. We need to grow 70% more food by 2050 to feed this growing world5; we are going to need all the tools we can get to accomplish this.

My farm grows GM crops, and I am proud to say that we do.  They are safe and sustainable crop options that we have the right to grow if we choose to. I hope that you will think about what I have said the next time someone asks you, “what do you think about GMOs?”
