Tractor Time Podcast Episode 8: André Leu, Author of The Myth of Safe Pesticides

In the Acres USA world, André Leu is becoming much more than a household name.

Andre Leu

Leu, who has written for our magazine for years, published The Myth of Safe Pesticides in 2014. He has spoken on the dangers of pesticides for years and several times at our Acres U.S.A. Eco-Ag Conference and Trade Show, and will join us again this year. He’s currently the president of IFOAM – Organics International, and has more than 40 yeas of international experience in all areas of organic agriculture. He has been one of those human advocates, one of those forces of nature, that are pushing the agriculture movement into healthier directions.

We spoke with Andre Leu on Thursday, July 20, from his office in Queensland, Australia.

Hosted by Ryan Slabaugh.

Drought Planning: Grassland Preservation

Drought planning and preparation should be a priority for most ranching operations, as ranches are likely to be located in areas of natural grassland and one of the formative factors for grasslands is erratic mois­ture availability. Drought is not just dry weather; drought occurs when there is a significant reduction in normal pre­cipitation. A desert area that received only 9 inches of rain is dry, but it is not in drought unless annual precipitation falls well below 9 inches; an area that is in a 40-inch rainfall belt and received 20 inches is in a serious drought.

Our home ranch in Nolan County, Texas, was in a 20-inch rainfall area that was very drought-prone; local wags said that the 20-inch average came about because it would rain 60 inches one year and then skip two years.

Build the health of your range, your bio­logical capital, when growing conditions are good so that you can survive the drought that is surely coming.

Where moisture availability is con­stant, the vegetation tends to be made up of longer-lived plants (trees). If drought kills most of the local vegetation, grass­es and forbs can germinate from seed and reproduce quickly, but trees require much more time to reach maturity. The fantastic ryegrass and clover pastures of England and Ireland did not come into being until the oak forests that were originally there disappeared into ship timbers and charcoal kilns. If humans were removed from these areas, the oak forests would return because of the uni­formity of the local moisture patterns.

The frequency and severity of droughts vary widely according to location; know­ing the probability of drought in the local environment is essential informa­tion for formulating drought planning management strategies. Equally important is recognizing the early signs of impending drought — the sooner drought is recognized, the more effectively its effects can be offset. If drought is recognized as a normal occur­rence, and it is, then plans can be made to reduce its impact upon the operation and upon the soil-plant-animal complex on which the operation depends.

The National Weather Service keeps detailed weather records for many places in the United States, and an examination of these records for your area is a good place to start in determining the likeli­hood of drought and need for drought planning. There is nothing you can do to keep drought from occurring, but you can do a great deal to reduce its impacts.

Interview: Author Judith Schwartz Examines Water Management

Modern Water Wisdom

Interviewed by Tracy Frisch

When writer Judith Schwartz learned that soil carbon is a buffer for climate change, her focus as a journalist took a major turn. She was covering the Slow Money National Gathering in 2010 when Gardener’s Supply founder Will Raap stated that over time more CO2 has gone into the atmosphere from the soil than has been released from burning fossil fuels. She says her first reaction was “Why don’t I know this?” Then she thought, “If this is true, can carbon be brought back to the soil?” In the quest that followed, she made the acquaintance of luminaries like Allan Savory, Christine Jones and Gabe Brown and traveled to several continents to see the new soil carbon paradigm in action. Schwartz has the gift of making difficult concepts accessible and appealing to lay readers, and that’s exactly what she does in Cows Save the Planet And Other Improbable Ways of Restoring Soil to Heal the Earth, which Elizabeth Kolbert called “a surprising, informative, and ultimately hopeful book.”

For her most recent project, Water in Plain Sight: Hope for a Thirsty World, Schwartz delves into the little-known role the water cycle plays in planetary health, which she illustrates with vivid, empowering stories from around the world. While we might not be able to change the rate of precipitation, as land managers we can directly affect the speed that water flows off our land and the amount of water that the soil is able to absorb. Trees and other vegetation are more than passive bystanders at the mercy of temperature extremes — they can also be powerful influences in regulating the climate.  

The week after this interview was recorded, Schwartz travelled to Washington, D.C., to take part in a congressional briefing on soil health and climate change organized by Regeneration International. As a public speaker, educator, researcher and networker, she has become deeply engaged in the broad movement to build soil carbon and restore ecosystems.

ACRES U.S.A. Please explain the title of your book, Water in Plain Sight.

JUDITH D. SCHWARTZ. The title plays on the idea that there is water in plain sight if we know where to look. It calls attention to aspects of water that are right before us but we are not seeing. By this I mean how water behaves on a basic level, not anything esoteric.

ACRES U.S.A. How should we reframe the problems of water shortages, runoff and floods?

SCHWARTZ. Once we approach these problems in terms of how water moves across the landscape and through the atmosphere, our understanding shifts. For example, when we frame a lack of water as “drought,” our focus is on what water is or isn’t coming down from the sky. That leaves us helpless because there’s really not much we can do. But if we shift our frame from drought to aridification, then the challenge becomes keeping water in the landscape. That opens up opportunities. Continue Reading →

Livestock Grazing: The Organic Farmer’s Dilemma

Livestock grazing organically is one of the hardest things to do, and a dilemma for most organic farmers. Why do most farmers farm the way they do? Because it’s easy — easy to spray, easy to buy technology, easy to plant with a no-till machine.

But it’s not always easy to make money, provide quality food, or be sustainable.

And about the way farmers care for their livestock? Locking them in a small box, calculating the “perfect ration,” and keeping it “simple”? When problems do show up, grab a drug — that’s easy! It’s a routine that can be taught. It’s certainly easy to get production and volume, but what about the well-being of that animal? And if we are what we eat, we have a problem.

And then there is organic farming. Is it easy? Well, the “not doing things” part is easy. If I just stopped all the negative practices and things went great, then organic would be easy, too. But is that a sustainable system for feeding the world and producing quality food? Organic can produce crops that yield as much as any other production system, but in more sustainable, environmentally friendly ways, providing better quality food while using less energy.

Soil Organic Matter: Tips for Responsible Nitrogen Management

For soil organic matter to work the way it should, it depends on a careful balance of nutrients and minerals, including one of

the most important elements — nitrogen. One of the great paradoxes of farming is that lack of nitrogen is regarded as one of the great limitations on plant growth, and yet plants are bathed in it because the atmosphere is 78 percent nitrogen.

Most plants cannot use nitrogen in this form (N2) as it is regarded as inert. It has to be converted into other forms — nitrate, ammonia, ammonium and amino acids for plants to utilize it.

In conventional agriculture most of these plant-available forms of nitrogen are obtained through synthetic nitrogen fertilizers that have been produced by the Haber-Bosch process.

High-Quality, High-Yielding Crops: Measure to Manage

High-quality, high-yielding crops are the goal for most farmers. But where do you begin? Some even insist that to have both is simply impossible to accomplish. For those who think that way, it will likely always be true. But for those who are looking for ways to improve and believe there is still room to do so, what should be considered first? And then where do you go from that point to make the most possible difference?

The soil’s physical structure can be measured and needed corrections determined by use of a detailed soil analysis.

To get high-quality, high-yielding crops, begin with the soil where they will be growing by performing the closest examination of all the most important factors needed to meet every possible requirement. What provides the most advantage to the crop from that soil? Some will feel the answer here is a heavy fertilizer program for the crop. Sufficient fertilizer is extremely important, but to achieve high-quality, high-yielding crops, there is another requirement that is also essential to assure the greatest value from whatever fertilizer is applied.

For each soil to perform at its best requires a balance of water, air, minerals and organic matter. Specifically, if you want the soil to do its best it should contain a balance of 50 percent solids (ideally 45 percent minerals and 5 percent humus) and 50 percent pore space (composed of 50 percent water and 50 percent air). This is the correct physical composition of extremely productive, high-performance soils. To be consistently efficient it is a necessary requirement to develop the most effective biologically active environment to build the needed extensively developed root systems of high-quality, high-yielding crops.
