Organic Certification?


Yesterday was the first part of the examination of the answer to the question that many have asked throughout the years. Today we finish with the article and look at some points that it raised.

Mary-Howell Martens is admired and recognized as one of the nation’s pioneering leaders in sustainable agriculture.

Together with her husband Klaas, Ms. Martens owns and operates Lakeview Organic Grain in Penn Yan, New York, one of the Northeast’s largest and most successful organic grain businesses.  Started in 1991, the Martens’ 1400-acre farm and feed mill, which they work with their children Peter, Elizabeth, and Daniel, and 10 employees, currently supplies organic feed and seed to over 300 organic livestock farmers in New York and Pennsylvania.

Is Organic Food More Nutritious Than Conventional Food? Part II

by Mary-Howell R. Martens

Animal nutritionists have noted a drop in nutritional quality of animal feed, especially corn and forages, over the past 25 years. Dave Mattocks of the Fertrell Company in Bainbridge, Pennsylvania, has been formulating animal rations for many years. He reports that he has had to continually increase quantity of protein sources in animal rations in order to maintain a constant level of protein. He feels that this reflects that the average protein level in grain has been dropping. When plants are induced to produce more quantity (higher yield), it is usually at the expense of something else, in this case, certain key molecules that affect quality and nutrition. Confirmation of this observation would probably be available if one took the time to sort through and analyze the reams of data that forage analysis labs have collected over the past 25 years.

Indirectly related to observations about declining feed quality, an article in the March 25, 2000 issue of Science News described research that showed that plants growing with increased air CO2 levels (as is possible in the future with the greenhouse gas effect) do indeed grow faster and produce more carbohydrates, but the protein levels are lower. Insects feeding on these plants eat excessively but grow poorly. Sheep eating such plants eat less, grow poorly, and digest their food more slowly, probably because the essential bacteria in the ruminant gut are themselves protein deficient and malnourished. This is important research that needs to be considered for several critical reasons. First, of course, because the Earth’s atmosphere is changing and we need to anticipate how this may effect vegetation and the organisms that feed on the vegetation. Secondly, this research can offer valuable insight into the critical factor of genotype-x environment interaction, a factor which is largely being overlooked in the biotech and Green Revolution discussions.

Regardless of all the other issues involved with genetically engineered crops, it seems logical that unless we pay attention to the soil and other environmental factors first, efforts to improve yield, nutrient content, or pest resistance of crops through genetics alone will be far less successful than they might be. Results obtained on well-managed research farms may not be repeatable on poorer soils that are not being as intensively managed. Most crops have far more genetic potential than they are able to express already. Producing high yields on poor soils without maintaining fertility levels will only postpone famine until the soil becomes exhausted. We should not see genetics alone as the solution to management problems, as a way that allows farmers to continue poor production practices on their farms. Many American farmers face a corn borer problem because they don’t rotate properly and use other practices, such as no-till, that allow large pest populations to build. Bt corn makes it easier to continue poor management practices, at least until pest populations develop resistance. Obviously, new traits could then be engineered into corn to control the resistant pests, but the underlying problem is still not being addressed by this approach.

Often, when discussions of the relative nutritional merits of organic versus conventional food come up, someone will invariably quote a 1948 study by Dr. Firman Bear at Rutgers University. Unfortunately, using this research to support any such claims is quite incorrect, because this study did not compare organic and conventional food. Instead, it compared crops grown in mineral versus organic (muck) soils, it had nothing to do with use of chemicals. However, perhaps Dr. Bear did get it right on one point. The research showed that the composition of the soil has a major and readily detectable influence on the mineral content and the nutritional quality of food. By better understanding the role that a healthy, microbially active soil can make on nutritional quality of plants, perhaps then we then can design agricultural systems that will maximize this. On an organic farm, careful attention is placed on improving soil quality, increasing soil organic matter, and enhancing soil microbial life, crops are carefully rotated and soil is specifically amended to balance all aspects of soil fertility. It makes logical sense to conclude that plants produced under such a system could indeed be more flavorful and nutritious.

Some comments and thoughts. First off, I agree with what is being said here, mainly that we shouldn’t be caught up in the “organic by default” trap that is so easy to fall into. What is meant by that is the simple absence of anything considered harmful does not equal healthy food. Simply because no pesticides, herbicides, fungicides,  chemical fertilizers, etc. etc. haven’t been applied, does not mean it is tasty and healthy. If nothing at all has been done to or with the soil, does that automatically mean all is well? Not really- there is much to be done in improving the fecundity of the soil including biological as well as structural improvements, organic matter, re-mineralization and nutrient balancing. Who would you want to eat produce from, one who has done nothing and calls it “organic” or one who has increased the biological health of their soil through careful and well researched amendments and inputs that are non-chemical in nature?

“There have been few studies that directly contrast the chemistry of conventional food to organic food.” Gosh, I wonder why… who normally funds such research? The Corporate Abgribusiness are not in the slightest interested if organic food is better, because that is not what they are in the business of.

“…over a two-year period, average levels of essential minerals were much higher in the organically grown apples, pears, potatoes and corn as compared to conventionally produced products. The organically grown food averaged higher in calcium, chromium, iron, magnesium, molybdenum, phosphorus, potassium and zinc, and lower in mercury and aluminum. A more recent study out of Australia showed a similar difference between calcium and magnesium levels in organic and non-organic food.” Yet when research is done, it conclusively shows that there are many more minerals that are essential for our health in organic, sustainably raised food.

“Weibel found interesting correlations between the microbial activity in the soil, a condition closely associated with organic management, and the nutritional status of the apples, especially the phosphorus level.” This is a perfect point of healthy soils equal much healthier produce. The correlation can be furthered to include healthier people from eating healthier produce… “This corroborates work done by Elaine Ingham at Oregon State University, who has shown that corn and grape plants grown in association with mycorrhizal fungi produce fruit with higher protein levels.” Mycorrhizal fungi are symbiotic fungi that greatly increase the nutrient uptake in plants and are essential to having biologically living, healthy soil.

Regardless of all the other issues involved with genetically engineered crops, it seems logical that unless we pay attention to the soil and other environmental factors first, efforts to improve yield, nutrient content, or pest resistance of crops through genetics alone will be far less successful than they might be.” Really? Do ya really think? Common sense would dictate that to ignore the very foundation of agriculture- the soil- would be to invite disaster on the scale of many of the world’s other civilizations that ignored their soil. Almost without fail, they do not exist anymore. Those that do are on such a diminished scale in comparison to where they used to be in production as to be almost unbelievable. Who would call Iran, Iraq and Syria “The fertile crescent” or “Breadbasket of the world” today? These are just 3 examples of those that have managed to survived the loss of their soils.

This is a great article that not only introduces some reasoned, rational thought to the perennial question of nutrition, it also introduces many to the thought of what does the term “organic” really mean, and what is it made up of? I really hope this raises more questions than answers and sets you on a direction of learning more about what you eat, where it comes from and how is it raised. Only by answering these and many other questions can you be a true part of the solution of helping to create more demand for healthy, nourishing, sustainably raised food.

Yes, this is work, it takes time, thought and energy, but unless you want to just sit back and consume whatever is sent your way by the advertising and corporate agribusiness giants, this is the only way.

Organic or Conventional?

This question is often asked, not only by those who are starting their reading and research into healthier foods, but by almost everyone at some point who actually stops and thinks about their food. This exact question has been the center of debate between the chemical and biological or sustainable agriculture communities for some years now. Those with large advertising budgets have spent dump truck loads of cash selling the public on the idea that there is no difference between spraying a custom mixed chemical slurry onto the soil and using compost, re-mineralization, green manures, proper crop rotation and building the soil health biologically. In fact, the advertising has sold the public and many farmers that the biological method is simply a waste of time and money. We are beginning to know better now.

The large Agribusiness companies are surprised and a little bit worried at the steady double digit growth of local and organic farming, and the reasoned, educated and dedicated support of that agricultural model through Farmer’s Markets, CSA’s, community gardening and farm shares. It can’t be ignored or brushed aside any more.  Many think that the Food Safety Modernization Act- S.510- is a large scale effort to seriously hamper the growth of  local biological agriculture. While a very small percentage of the total market share, the growth of local agriculture has the industry giants concerned, because if only 5-7 percent of the current market departed, that would mean losses in the tens of millions of dollars for them. That is completely unacceptable for the corporations, and their shareholders that control modern Agribusiness.

We wanted to present an article from one who is recognized as being quite knowledgeable in the field. From a basis of formal education leading to real world advisory positions in policy making governmental departments, she has the foundational knowledge to be able to speak authoritatively on the subject. Her own experiences as an award winning organic grain farmer who also educates others how to produce abundance without the chemicals now thought to be essential to successful large scale agriculture uniquely qualifies her to be able to speak on both sides of this question.

In addition to her agribusiness endeavors, Ms. Martens, a graduate of the Cornell University College of Agriculture and Life Sciences, served on the USDA Advisory Committee on Agricultural Biotechnology from 2000-2002, and on the Cornell University’s College of Agriculture and Life Science’s Dean’s Advisory Committee from 2003-2009.  She is also a member of the New York State Department of Ag and Markets’ Organic Advisory Committee and the Yates County Farm Bureau Board of Directors, in addition to numerous community volunteer efforts.

Is Organic Food More Nutritious Than Conventional Food?

by Mary-Howell R. Martens

Is organic food more nutritious or better tasting than conventionally produced food? This is a question that many people are asking, but unfortunately, there is no simple answer. So much more is involved in the nutritional quality of food than simply comparing organic versus chemical agronomic practices. There is certainly quite a bit of incorrect information, confusion, and wishful thinking on both sides concerning this subject, and probably there is as much variation in food quality produced on different organic farms as there is in the quality of food produced on different conventional farms.

Many people do believe that they can taste a difference between organic and nonorganic food. I usually think I can, but that might be because organic food is often fresher and more likely to be locally produced. Margaret Wittenberg, of Whole Foods Inc., says that in their stores, when customers ask whether organic foods are more nutritious, the company policy is to say that there is no evidence to say that this is true. However, she says that many customers remain unphased with this answer due to their own experiences and perceptions.

Some animals apparently can detect a difference in organic crops by taste. Floyd Hoover, in Penn Yan, New York, grows organic corn. One night he left several ears of conventional and organic corn side by side in his barn. The next morning, the organic corn had been nibbled by mice while the conventional corn had been ignored. Floyd then rearranged the order of the cobs, but still the mice avoided the conventional corn. Finally, he hid the organic corn, but the mice refused to touch the conventional corn. Within a few nights, the mice found the hidden organic corn and had a feast. Anecdotal evidence such as this indicate that for many people and apparently animals too, detectable quality differences do exist. Scientifically, however, it is difficult to draw definitive comparisons about the nutritional quality of conventional and organic food. Many environmental factors influence the nutritional quality and flavor of any type of farm product, including soil type, soil moisture, soil microbial activity, weather and other climatic conditions. Cultural practices, such as crop variety, seed source, length of growing season, irrigation, fertilization, cultivation, and post-harvest handling, will also affect food quality.

There have been few studies that directly contrast the chemistry of conventional food to organic food. Research reported in the Journal of Applied Nutrition showed that on a per-weight basis over a two-year period, average levels of essential minerals were much higher in the organically grown apples, pears, potatoes and corn as compared to conventionally produced products. The organically grown food averaged higher in calcium, chromium, iron, magnesium, molybdenum, phosphorus, potassium and zinc, and lower in mercury and aluminum. A more recent study out of Australia showed a similar difference between calcium and magnesium levels in organic and non-organic food.

Simply knowing the absolute quantity of chemical elements in a food sample may not be particularly revealing if we don’t know what molecules those elements are incorporated into in the food product. The same simple chemical elements may be organized into nutritious and flavorful molecules or may be organized into toxic, unpleasant-tasting molecules, or even into molecules that render plants more susceptible to insects and diseases. Certain amino acids such as proline have been linked to increased insect feeding and egg laying behavior. A plant slightly deficient in potassium may lack enzymes necessary to convert free amino acids into complex proteins. Another plant with adequate potassium might not show detectable differences in overall nitrogen level, but would contain more protein, might be much different in food flavor and quality, and might be much more resistant to insect attack.

It is possible to identify the specific chemical molecules that cause the typical characteristics we call “flavor” or “quality.” These generally are large, complex molecules, such as sugars, proteins, enzymes, esters, and organic acids. In a preliminary study, Dr. Franco Weibel at the Research Institute of Organic Agriculture in Ackerstrasse, Switzerland, compared a variety of parameters in apples grown under organic and conventional conditions, such as mineral elements, sugars, phenols, malic acid, selenium, dietary fiber, and vitamins C and E. Organic fruit also had significantly firmer flesh and better sensory taste evaluations. Weibel found interesting correlations between the microbial activity in the soil, a condition closely associated with organic management, and the nutritional status of the apples, especially the phosphorus level. The actual chemical soil phosphorus level had little impact on fruit nutritional status. This research also found that organic fruit was considerably higher in phenols. Plants naturally synthesize phenols for defense against pests and diseases. Possibly, the unsprayed organic plants were stimulated to make higher levels of these critical molecules in response to pest attack. These phenolic compounds that protect the plant also have been shown to be disease protectants in humans. This corroborates work done by Elaine Ingham at Oregon State University, who has shown that corn and grape plants grown in association with mycorrhizal fungi produce fruit with higher protein levels.

Research conducted at Ohio State University by Dr. Larry Phelan has shown that European corn borer insects given a choice between organic and conventional corn plants avoid the organic plants. His research is continuing to test two hypotheses for these observations. He feels that the organic soils, with a rich microbial population, may release  plant nutrients more evenly over the season, resulting in slower, sturdier plant growth that is more resistant to insect attack. He also believes that the mineral balance of the soil and the plant plays a key role in insect resistance. In either case, the levels of complex molecules and water content in the plant tissue probably determines how tasty the plant is to an insect.
