How Organic Farming Could Release Us From the Curse of Fertilizer

Environmental pollution is a significant problem. But while most of the focus is placed on polluting industries, toxins like mercury and small particle traffic pollution, a major source of environmental devastation is caused by modern food production. Far from being life sustaining, our modern chemical-dependent farming methods:

  • Strip soil of nutrients
  • Destroy critical soil microbes
  • Contribute to desertification and global climate change, and
  • Saturate farmlands with toxic pesticides, herbicides and fertilizers that then migrate into ground water, rivers, lakes and oceans.

For example, many areas of Minnesota, which is prime farmland, now face the problem of having dangerously elevated levels of nitrogen in their drinking water.

The conversion of grasslands and pastures into chemical-driven, industrial crop land has eliminated much of the natural filtering of ground water that such native landscapes typically provide. Health risks of nitrogen include a potential connection to cancer, as well as thyroid and reproductive problems in both humans and livestock.

Looming Fertilizer Shortage Could Spell the End of Modern Agriculture

Modern fertilizer consists of varying amounts of nitrogen (N), phosphorus (P) and potassium (K). These three are believed to be essential for plants to grow, (below, I’ll discuss why NPK may not be as necessary as we think.), and are extracted from the soil with each harvest.


This is why farmers spread fertilizer on their fields, to replace the nutrients lost. It’s certainly not the ideal and sustainable way to farm, but it’s thought to be the most efficient for large-scale farms. Strategies like crop rotation and allowing large fields to rest would cut too deep into profits that are based on quantity, opposed to quality.

Unfortunately, the Earth’s soil is now being depleted of nutrients at more than 13 percent the rate it can be replaced. Not only that, but according to some, we may also be facing looming shortages of two critical fertilizer ingredients: phosphorus and potassium.

A 2012 article in Mother Jones1 discussed “peak phosphorus and potassium,” drawing lines of similarity between the diminishing reserves of these natural elements and “peak oil.”

Unlike nitrogen, phosphorus and potassium cannot be synthesized, and our aggressive large-scale farming methods, which deplete soils of nutrients that then must be replaced, are quickly burning through available phosphorus and potassium stores.

According to well-known investor Jeremy Grantham, writing for Nature:

“These two elements cannot be made, cannot be substituted, are necessary to grow all life forms, and are mined and depleted. It’s a scary set of statements. Former Soviet states and Canada have more than 70 percent of the potash. Morocco has 85 percent of all high-grade phosphates. It is the most important quasi-monopoly in economic history.

What happens when these fertilizers run out is a question I can’t get satisfactorily answered and, believe me, I have tried. There seems to be only one conclusion: their use must be drastically reduced in the next 20-40 years or we will begin to starve.”

This largely unknown issue may end up playing a more significant role than you can currently imagine, because it cuts to the heart of the sustainability of modern agricultural practices, or rather the lack thereof.

“[T]he next time someone facilely insists that the ‘industrial farms are the future,’ ask what the plan is regarding phosphorus,” Mother Jones writes. “Developing an agriculture that’s ready for a phosphorus shortage means a massive focus on recycling the nutrients we take from the soil back into the soil—in other words, composting, not on a backyard level but rather on a society-wide scale.

It also requires policies that give farmers incentives to build up organic matter in soil, so it holds in nutrients instead of letting them leach away… Both of these solutions, of course, are specialties of organic agriculture.”

Monoculture vs. Polyculture

Monoculture (or monocropping) is defined as the high-yield agricultural practice of growing a single crop year after year on the same land, in the absence of rotation through other crops. Corn, soybeans, wheat, and to some degree rice, are the most common crops grown with monocropping techniques. In fact, corn, wheat and rice now account for 60 percent of human caloric intake, according to the UN Food and Agriculture Organization.2

By contrast, polyculture (the traditional rotation of crops and livestock) better serves both land and people. Polyculture evolved to meet the complete nutritional needs of a local community. Polyculture, when done mindfully, automatically replenishes what is taken out, which makes it sustainable with minimal effort.

If it’s true that we may at some point face a shortage of phosphorus and potassium, large-scale farming facilities would be hard-pressed to produce much of anything after a short while. Such shortages might even lead to geopolitical strife, as phosphate rock is primarily concentrated in the occupied territory of the Western Sahara region of Morocco. It may sound farfetched to some, but how far would a nation go to secure access to such a location if the future of the entire agricultural industry and food supply depended on it?

Monocropping Is NOT the Way to Feed a Growing Population

The evidence tells us that forging more sustainable alternatives is imperative if we hope to survive. Yet proponents of factory farms and genetically engineered crops argue that monocropping, or crop specialization, is the only way to feed the masses and that it’s far more profitable than having small independent farms in every township.

But is this really true? A number of studies show just the opposite! In fact, studies are showing that medium-sized organic farms are far more profitable than ANY sized industrial agricultural operation.

For example, researchers at the University of Wisconsin’s College of Agriculture and Life Sciences and Michael Fields Agricultural Institute3 (results published in 2008 in the Agronomy Journal)4 found that traditional organic farming techniques of planting a variety of plants to ward off pests is more profitable than monocropping. The organic systems resulted in higher profits than “continuous corn, no-till corn and soybeans, and intensively managed alfalfa.”

Not only that, but organic farming practices use natural, time-tested techniques that naturally prevents soil depletion and destruction, and doesn’t use chemical fertilizers and other agricultural chemicals that pollute our soil, air, and waterways.

In the study just mentioned, the researchers concluded that government policies supporting monoculture are “outdated,” and that it’s time for support to be shifted toward programs that promote crop rotation and organic farming. As it turns out, when you eliminate the agricultural chemicals, specialized machinery and multi-million dollar buildings, fuel costs, insurance costs, and the rest of the steep financial requirements of a big industrial operation, your cost of producing food takes a serious dive into the doable. And did I mention… the food from organic farms tend to be far more nutritious, besides being free of toxic contaminants?

Even the US Department of Agriculture (USDA) is starting to question our current path of monoculture. It recently released a report titled: “Climate Change and Agriculture in the United States.”5 According to the report, our current agricultural system, which is dominated by corn and soy, is unsustainable in the long term. Should temperatures rise as predicted, the US could expect to see significant declines in yields by the middle of this century. Food shortages would be inevitable, since little besides these crops are grown. (Keep in mind the primary crops grown in the US are used in processed food production, so countless numbers of food products would be affected by massive crop loss.)

Nitrogen Overuse Threatens the Environment

Going back to where we started, the overuse of nitrogen in farming is causing far more environmental devastation than many currently comprehend. A recent National Geographic article6 addresses this issue:

“’Runaway nitrogen is suffocating wildlife in lakes and estuaries, contaminating groundwater, and even warming the globe’s climate. As a hungry world looks ahead to billions more mouths needing nitrogen-rich protein, how much clean water and air will survive our demand for fertile fields?’

China, the world’s largest producer of synthetic nitrogen, has hundreds of nitrogen factories, and the country’s farmers apply vast amounts of nitrogen to their fields. One rice farmer reports spreading no less than 530 pounds of urea, a dry form of nitrogen, on each acre. Vegetable farmers use even more than that. According to the featured article,7 some use upwards of two tons of nitrogen each hectare (2.47 acres).

‘Few of them think they’re doing anything harmful. No, no pollution,’ says Song, when asked about the environmental effects of fertilizer,’ the article states. “Scientists tell a different story. ‘Nitrogen fertilizer is overused by 30 to 60 percent’ in intensively managed fields, says Xiaotang Ju, of the China Agricultural University in Beijing. ‘It’s misuse!’ Once spread on fields, nitrogen compounds cascade through the environment, altering our world, often in unwelcome ways. Some of the nitrogen washes directly from fields into streams or escapes into the air. Some is eaten, in the form of grain, by either humans or farm animals, but is then released back into the environment as sewage or manure from the world’s growing number of pig and chicken farms.”

Water pollution, as mentioned earlier, is one of the side effects of such overuse. In a matter of decades, rivers that used to run crystal clear though Chinese provinces are now cloudy from overgrowth of phytoplankton, fed by fertilizer runoff from the fields. According to National Geographic:

“A recent national survey of 40 lakes in China found that more than half of them suffered from too much nitrogen or phosphorus. (Fertilizer containing phosphorus is often to blame for algal growth in lakes.)

The best known case is Lake Tai, China’s third largest freshwater lake, which regularly experiences huge blooms of toxic cyanobacteria. A spreading bloom in 2007 contaminated water supplies for two million people in the nearby city of Wuxi. Excess nutrients are damaging fisheries in China’s coastal areas in the same way that fertilizer runoff flowing down the Mississippi has destroyed fisheries in the Gulf of Mexico: by creating dead zones in which algae and phytoplankton bloom, die, and decompose, using up oxygen and suffocating fish.”

Finding the Middle Ground of Good Harvests with Reduced Fertilizer Pollution

National Geographic describes a research project in Michigan that has been ongoing for the past two decades. The project is part of Michigan State University’s Kellogg Biological Station, near Kalamazoo. Here, fields that are exactly one hectare in size provide side-by-side comparisons of four different farming methods, ranging from conventional to organic. Everything that is added to or removed from each field is carefully measured, including rainfall, fertilizer, nitrous oxide, water that leaches into groundwater, and the harvest itself. According to the article:

“Each field planted according to standard plowing and fertilizer recommendations released 610 pounds of nitrogen per acre into Michigan’s shallow groundwater over the past 11 years… The organic fields in Robertson’s experiment, which received no commercial fertilizer or manure, lost only a third as much—but those fields also produced 20 percent less grain.

Intriguingly, the ‘low input’ fields, which received small amounts of fertilizer but were also planted with winter cover crops, offered the best of both worlds: Average yields were about as high as those from the conventional fields, but nitrogen leaching was much reduced, almost to the level of the organic fields.

If America’s farmers could cut their nitrogen losses to something close to this level… restored wetlands and revived small streams could clean up the rest. As in China, though, many farmers find it hard to change. When a family’s livelihood is at stake, it may seem safer to apply too much fertilizer rather than too little. ‘Being a good steward currently has economic consequences that are unfair,’ says Robertson.”

How Sustainable Soil Science Can Help Rescue Our Environment and Food Supply

I recently interviewed Dr. Elaine Ingham,8 an internationally recognized expert on the benefits of sustainable soil science. I also recently visited her at her new position at the Rodale Institute in Pennsylvania. According to Dr. Ingham, a key component of successful agriculture lies in having the right helper organisms in the soil; beneficial species of bacteria, fungi, protozoa, beneficial nematodes (not the weedfeeders), microarthropods, and earthworms—all of which contribute to plant growth in a number of different ways.

Nutrient cycling is another major issue. According to Dr. Ingham, there’s no soil on Earth that lacks the nutrients to grow a plant. She believes the concept that your soil is deficient and needs added phosphorus or nitrogen etc in order to grow plants is seriously flawed, and largely orchestrated by the chemical companies, because it’s based on looking at the soluble, inorganic nutrients that are partly present in your soil.

The real nutrition your plants require is actually derived from microorganisms in the soil. These organisms take the mineral material that’s in your soil and convert it into a plant-available form. Without these bioorganisms, your plants cannot get the nutrients they need. So what you need is not more chemical soil additives, what you need is the proper balance of beneficial soil organisms. According to Dr. Ingham:

“It’s very necessary to have these organisms. They will supply your plant with precisely the right balances of all the nutrients the plant requires. When you start to realize that one of the major roles and functions of life in the soil is to provide nutrients to the plants in the proper forms, then we don’t need inorganic fertilizers. We certainly don’t have to have genetically engineered plants or to utilize inorganic fertilizers if we get this proper biology back in the soil.

If we balance the proper biology, we select against the growth of weeds, so the whole issue with herbicides is done away with. We don’t need the herbicides if we can get the proper life back into the soil and select for the growth of the plants that we want to grow and against the growth of the weedy species.”

Interestingly enough, you can use a starter culture to boost the fermentation and generation of beneficial bacteria much in the same way you can boost the probiotics in your fermented vegetables. For compost, this strategy is used if you want to compost very rapidly. In that case, you can use a starter to inoculate the specific sets of organisms that you need to encourage in that compost.

For optimal physical health, you need plant foods to contain the full set of nutrients that will allow the plant to grow in a healthy fashion, because that’s the proper balance of nutrients for us human beings as well. Dr. Ingham has written several books on this topic, including The Field Guide for Actively Aerated Compost Tea, and The Compost Tea Brewing Manual.

How to Help Support Sustainable Agriculture

If you want to optimize your health, you simply must return to the basics of healthy food choices and typically this includes buying your food from responsible, high-quality, sustainable sources. This is why I encourage you to support the small family farms in your area. This includes not only visiting the farm directly, if you have one nearby, but also taking part in farmer’s markets and community-supported agriculture programs.

Not only is the food so much tastier and healthier when you get it from sustainable, non-CAFO sources, but there is something about shopping for fresh foods in an open-air, social environment that just feels right. An artificially lit, dreary supermarket — home to virtually every CAFO food made — just can’t compete. If you want to experience some of these benefits first-hand, here are some great resources to obtain wholesome food that supports not only you but also the environment:

  2. Farmers’ Markets — A national listing of farmers’ markets.
  3. Local Harvest — This Web site will help you find farmers’ markets, family farms, and other sources of sustainably grown food in your area where you can buy produce, grass-fed meats, and many other goodies.
  4. Eat Well Guide: Wholesome Food from Healthy Animals — The Eat Well Guide is a free online directory of sustainably raised meat, poultry, dairy, and eggs from farms, stores, restaurants, inns, and hotels, and online outlets in the United States and Canada.

    I am shocked that Dr Mercola, who claims expertise in nutrition, would not only fall for this absurdity but promote it.

  • Between the article and the comments the complexity of producing a high yield plants of high nutritional value that don’t attract pests is covered pretty well. Dr. Ingham covers one leg of the stool, the importance of soil microbes, but saying that “any soil can grow plants” is not the same as saying any soil can produce high quality, very nutritious plants just with the right microbes. Rock dusts (and sea minerals, for that matter) add the important element of a wide variety of trace minerals which can have a major impact on quality, but may not overcome a major mineral imbalance. It’s true that microbes can pull nitrogen from the air, and make insoluble potassium and phosphorus available to the plant, but if calcium, sulfur, zinc, etc. are in short supply, you are not going to get the most nutritious result, even if you get a plant that looks good. That’s where the 3rd leg of the stool comes in – soil mineral balancing. Joel Salatin may get excellent results on his farm in Virginia or Dr. Ingham at the Rodale Institute in Pennsylvania, but I know someone in Oregon who tried all these techniques, but just didn’t get satisfactory results until she did some soil testing and corrected the mineral imbalances. The important news is that you don’t need chemical fertilizers and pesticides or GMO seeds or huge monocultures to get top notch results and feed the world. Instead we need to stop pushing peasant farmers off their land from which they feed themselves and teach them the above techniques so they can be far more productive and also feed the city folk near them!

    Both of the above comments are partially true. 1) Microbes convert minerals into a plant available form that plants can use. 2) Minerals must be present in the soil or there is nothing for microbe to convert.

    However, Dr. William Albrecht discovered that mot only do the minerals have to be present in the soil but they also have be in specific proportions (base saturation) to each other or they will tied up due to mineral imbalances.

    What this means is that not only do you need to remineralize your soil but this remineralization must be done properly or you will still have mineral tie up due to mineral imbalances in your soil.

    Therefore, until soils are remineralized according to the Albrecht model of soil balancing you will have mineral tie-up leading to mineral deficiencies in plants leading to weak plant cell structure leading to plant disease and insect infestation.

    Suggested learning resource would be Acres USA and the Albrecht papers which are available thru Acres USA. For an agronomist – Neal Kinsey.

      I think that you must be referring to loading of chemically produced minerals into soil to create such an imbalance.

      Consider this irrefutable truth, that all rock is originally igneus, and that that is what is weathered down into rock soil, which takes 20,000 years to form by wind, and water ablation of rock surfaces, rocks braking up by freezing and thawing etc., and that this rock dust is the soil on which all plants have then grown, without anyone telling them that they need to filter that rock somehow or the minerals won’t be balanced properly.

      Basalt rock dust is THE already perfectly balanced mineral formula, and there isn’t any better. Many crops grown mixing that into soils are 2 to 4 times larger, full stop. Plants grow on the stuff and have done for thousands of millions of years without any mineral mix formula from Dr. William Albrecht, and the micro-organisms that they need develop and thrive perfectly naturally in such a soil.

      Only man foolishly ploughs soil so that the surface of the land is torn open and vulnerable to water and wind erosion. We need to drill seeds instead, or plant under a layer of mulch, to prevent mineral rock dust erosion.

    Visit ‘Mothman777’s Blog’ to read the following essay, ‘Basalt And Other Rock Dusts, How To Totally Remineralize Your Soil – with a refutation of the University of Glasgow 2009 PhD thesis on rockdust and composted materials – revised 19th January 2012′

    Rock dusts are the only way to fully remineralize soil and vastly increase crop yield whilst at the same time making the crops much hardier against pests and disease. Adding rock dusts to growing media is the way to feed everyone properly with food that will give optimal health, brain development and function.

    Samuel Epstein stated that 95% of all disease is due to mineral deficiency. Rock dusts completely remineralize soil, including microminerals that have been demonstrated to double lifespans in tests on animals. Think what they could do for us, and the quality they could add to our lives also.

    Quarries should mine this stuff full time for the agricultural industry. With this strategy, we can solve malnutrition (I know already about all the food destroyed each year to artificially create high prices, and about food mountains, logistics problems etc.).

    The racist depopulation agenda with GMO can be stopped right now if we all demand a return to organic farming with rock dusts rather than chemical NPK fertilizers and other chemicals, like glyphosate, that is proven to sterilize all animals who consume it, with immense harm also demonstrated to mens’ testes and sperm-producing cells, with massive loss in mens’ fertility at extremely minute levels of contamination, way below the official amounts currently allowed as ‘safe’ in our food and water.

    Chemical fertilizers just pump plants up with water and extremely low mineral content. For instance, according to Mike Adams, an apple grown today has only 3% of the mineral content of one grown in 1916. It is the case that we must all demand rock dust be used or continue to eat garbage food, suffering poor mental and physical development as a consequence, as well as becoming victims of big pharma.

    Results obtained from using rock dusts completely blow any arguments for GMO’s right out of the water. Please spread the word about rock dust as enthusiastically as possible, to your local politicians, agricultural ministries/departments and farmers.

    Insist on quality food that only rock dust can help to grow. Rock dust is, after all, the ultimate source of all soil, and when it is minerally depleted, there is really only one source to go to in order to make things right again, and rock dust is the only fully complete choice. The planet is made of the stuff, there is plenty of it and no shortage, and no patent can be put on it, no fancy manufacturing process is needed to make the stuff, it is made by God fully complete already.

    Why do you think the governments don’t tell you about basalt rock dust and authorize it’s use on all farms in every country of the world? Because it would undermine their Agenda 21 depopulation strategy, that is why, and they want the mass population weakened by constant ill-health, and poverty trying to pay for treatments (which don’t work, intentionally).

    Everyone should demand that their local government representatives propose the use of basalt rock dust on a national level, so that food can become properly nutritious again, a genuine medicine in fact, and so that no more toxic run-off destroys life in our lakes, rivers and marine estuaries. Remember, 80% of the oxygen we breathe comes from plant micro-organisms in the sea, and when the pH value of the water is disturbed by agrochemical run-off, oxygen levels are changed.
