HSHW 2018 at the Conservation Tillage and Technology Conference

The fifth Healthy Soils for Healthy Waters Symposium was held March 6th and 7th at the Conservation Tillage and Technology Conference in Ada, Ohio. Almost 900 crop consultants, producers, and subject experts were in attendance. The series is dedicated to a whole systems approach to agricultural land management. The objective is to optimize management for healthy soils, nutritious foods, clean water, and farm profits. This year we had experts speaking on building soil health, regenerative agriculture, healthy foods, precision nutrient management, and healthy waters.

We thank Randall Reeder, Alan Sundermeier (Healthy Soils Healthy Environment at OSU Extension), the CTC team, moderators, and speakers. Special thanks to our sponsors, Exactrix and TKI Crop Vitality. Speakers represented an impressive range of organizations including Ohio State University, USDA-NRCS, USDA-ARS, Iowa State University, University of Washington, Ohio Farm Bureau, The Nature Conservancy, MillerCoors, Cooper Farms, University of Waterloo, Purdue University, Legacy Farms, Agren, and farmers.

Barry Fisher (Region Soil Health Team Leader, USDA-NRCS) kicked off the event by highlighting the benefits of no-till and cover crops on soil and illustrated how aggregate stability is improved in a no-till system.

David Montgomery (University of Washington) spoke on the importance of “Ditching the plow, Covering Up, and Growing Diversity.” David’s books include Dirt: The Erosion of Civilization, The Hidden Half of Nature, and Growing a Revolution: Bringing the Soil Back to Life. In Growing a Revolution, David consulted many innovative producers across the world who are regenerating their soils and protecting the environment while maintain profitability. David Brandt (Ohio producer) joined him onstage in describing practices he is using on his own farm in Ohio and the benefits he has seen from using cover crops and no-till including reducing his use of inputs (fertilizers and herbicides).

Healthy Soils for Healthy Waters 2017

Barry Fisher, Joe Nester, Paul Jasa, Dave Brandt, Guy Swanson, and John Aeschliman

The 2017 Healthy Soils for Healthy Waters (HSHW) Symposium took place February 1st in Denver at the National Association of Conservation Districts Annual Meeting with a national audience learning from expert producers and researchers. The symposia series is dedicated to integrated and whole systems approaches to agricultural land management practices that protect the availability and quality of land and water resources while generating profitable crop production. At this symposium, 6 of the 25 recognized “No-Till Legends” were panelists or in attendance. This year we brought together the speakers below whose work preserves resources in the Western, Midwest, and Southern United States and as far as Australia.


Brian Richter
is Chief Water Scientist at The Nature Conservancy and the Founder of Sustainable Waters. As a Colorado native who has counseled governments and institutions around the world on sustainable water resource solutions, it was only natural that Brian served as the keynote speaker. Brian presented a “recipe for a sustainable water future” focused on setting sustainable limits on water extraction, reducing water consumption, quantifying rights to use available water, and enabling water trading. Brian has authored many articles and books including Chasing Water: A Guide for Moving from Scarcity to Sustainability. Brian presented on how we can save water through improving irrigation practices, changing crops, using no-till farming and other practices, and how water markets and water rights trading are being utilized to advance sustainability goals. See Brian’s slides here.

Jeff Mitchell is a Cropping Systems Specialist at the University of California-Davis Extension whose research focuses on soil and water management in vegetable production systems in the Central Valley, one of the most productive agricultural regions in the world. California’s Irrigated Lands Regulatory program requires that farmers use best management practices to limit nutrient runoff in the waterways, including the monitoring and reporting of water quality to protect surface and groundwater. Jeff stressed that no-till systems benefit water quantity, infiltration, crop quality and other environmental benefits, drawing on the example of how one farm avoided excess irrigation through no-till and high residue planting. See Jeff’s slides here.

Mike Taylor and his son, Michael are farmers in Phillips County, Arkansas. Mike reminds us that, “We do not inherit the Earth from our ancestors, we borrow it from our children.” Early on Mike discovered that the tilled areas of his farm were susceptible to erosion, and that the soil was relatively devoid of microbial life. Wanting to improve the quality of his soil, Michael turned to no-till, cover crops and direct seeding. Combined, these practices have improved his now “living” soil and associated expansive plant root systems. In 2014, Michael received a “Yield Chaser Award” for producing soybean yields of 96 bushels per acre on restored farmland. See Mike’s slides here.

John Aeschliman farms on the steep slopes of Colfax, Washington in soils that can run 400 feet deep. He has to manage land that erodes into gullies given the great gradient of the rolling landscape. Over his forty plus years of farming John has discovered how cover crops and direct seeding reduce runoff by improving soil microbial activity and the rhizosphere. Through these practices, John has increased valuable soil organic matter in his fields. See John’s slides here.

Keith Thompson is a producer growing corn, soybean, milo, wheat, sunflowers, and cover crops in rotation on his Kansas acreage. He spoke on the synergy between diversity of crops, intensity of practices, and rotation. Keith’s practices highlight how soil health and crop yields benefit from a variety of practices. For example, when Keith introduced livestock grazing on his landscape their manure and soil disturbance yielded microbes that previously were missing in the soil. By restoring some of the microbial community that are common to native prairies, Keith nurtured a return to soil conditions and makeup that were more resilient to weather extremes and disease or infestation. Crop diversity helps to control weeds (by providing ‘inconsistencies’ that challenge the static or constant habitat condition many weed plants prefer). See Keith’s slides here.

Barry Fisher is the Central Region Leader for the Soil Health Division of NRCS. He was given the Conservation Legacy Award from NRCS for his contribution to ‘Unlock the Secrets of the Soil’ Campaign‘ on soil health. He presented several principles that guide best management practices as is understood by soil scientists today: 1) seek to provide continuous living roots; 2) minimize soil disturbance; 3) maximize biodiversity; and 4) maximize soil cover. Indicators of soil health include organic matter, aggregate stability, water infiltration, water holding capacity, nutrient cycling and balancing soil biology. Improved soil health leads to more resilient crops. See the image comparing no-till with a cover crop to minimum no-till where the no-till and cover crop field became more resilient to threats (weather and pests).

Joe Nester is a leading crop consultant in the Midwest and who manages the Maumee Adapt Network to protect the agricultural intensive Western Lake Erie Basin. His research with The Ohio State University and Michigan State University has focused on a suite of practices to optimize soil health and crop productivity while minimizing loss of nutrients (especially P) into the area waterways that cause harmful algal blooms. Joe initiated ongoing research into how changes in rainfall pH effects soluble phosphorus. The research has demonstrated that a rise in soil pH from reduced acid rain coupled with the plant harvesting of sulfur from the soil is correlated with sulfur deficits in the soils and associated increased pH and solubility of phosphorus. Based on these experiments, Joe suggests that rainfall pH could be a major contributing factor to the change in phosphorus export, and that nutrient management has significantly improved nutrient runoff despite the increased solubility of phosphorus. He advocates that a range of good agricultural practices like 4Rs (right source, right rate, right time, right place) and cover crops, can minimize stress on crops and that there is not one single solution but rather a suite of practices is required. See Joe’s slides here.

Carrie Vollmer-Sanders is Nutrient Strategy Manager for The Nature Conservancy working from the Chesapeake Bay to the Mississippi and Great Lake Systems and points between. She helped develop the 4R Nutrient Stewardship Program and at our Symposium discussed the “trinity” of agriculture: soil health, water quality and nutrient management, and how all help to address erosion, yield, and water quantity issues. The Nature Conservancy has introduced reThink Soil which provides a roadmap for researchers and farmers based on science, economics, and policy.

Paul Jasa is an Extension Engineer from the University of Nebraska working on crop production programs that build soil health and profitability for producers. Paul stressed that tillage has never built soil health, but rather no-till and cover crops allow for the residue to be broken down and reutilized into the soil. Soils are active with dynamic microbial life and physical chemistry processes that depend upon these organisms for performance.

The Healthy Soils for Healthy Waters Steering Committee is delighted to work with this talented group of leaders, and the many active participants from NACD’s national membership, to advance the sustainable use of our nation’s agricultural landscape that feeds the world. We thank the Healthy Soils for Healthy Waters Sponsors, KB Seed Solutions, Green Cover Seed, Exactrix and Gypsoil for their support. We look forward to working with interested parties in part through this ongoing symposia series to protect these vital land and water resources, and we welcome hearing from you regarding how we can address this mission.

Celebrating World Soil Day today – Healthy Soils for Healthy Waters Conference in Memphis

December 4, 2015 – World Soil Day

Celebrating World Soil Day today – Healthy Soils for Healthy Waters Conference in Memphis

This week 200+ of the nation’s agricultural leaders assembled in Memphis, TN at the Healthy Soils for Healthy Waters (HSHW) symposium to advance sustainable practices and supportive policies for feeding a growing world population while protecting the fertile soils and surrounding water resources we depend upon.  The timing of our gathering was perfect given that today is World Soil Day with global events echoing our call for preservation of the planet’s envelop of productive soils that drape our globe.  You can find here the full agenda of the Nutrient Management conference that focused on the Great Lakes and Mississippi watersheds, which drain two thirds of the continental United States.  The day one HSHW symposium included presentations from across the business, policy, research, and environmental sectors and you can find summaries of their talks here. Days two and three saw a continuation of the HSHW themes with presentations from various regions.

But allow me to highlight just a few comments, especially from the producers (farmers) who know best what it takes to manage and protect their lands.

Dan DeSutter, a producer from Indiana, reminded us that ‘nature is our template’ … it is complex and we must study and mimic it in our actions as we work to effectively pump carbon back into plant roots to grow organic matter, while facilitating soil biology and increasing diversity which is a hallmark of healthy natural systems.  He reminds us there ‘is more living matter in a teaspoon of soil than people on the planet.’  Dan talks about fungi as ‘soil livestock’ that need to be fed air and water to breathe and multiply.  When the going gets tough, he says, the survivors diversify … so the lesson he takes away is to diversify his crops.

Mike Taylor, a producer from Arkansas, echoed this call for diversifying crops to retain nutrients.  He quoted Charles Kome, stating that “the quality of our air, water, and food is all dependent upon the quality of our soil!”  And David Brandt, a producer from Ohio, spoke of planting 8-12 different species in his diversification strategy to maximize productivity and maintain soil health.  David afterwards shared with me that his soil management strategies yield crops with a measured nutrient density double that of his neighbor’s crops – that means a given weight of grain from David’s fields sold to feed our cattle as well as the food products that feed ourselves contains double the micro and macro nutrient value coming off fields with poorer soil management.  Yet they get the same price in the markets when weighed at the grain elevator!  Healthy Soils for Healthy Foods and Healthy People is a priority of Greenleaf and its partners.

FAOAndrew Sharpley, Professor of Soil and Water Quality at the University of Arkansas, summed up the first day by putting up an image of medicine with a warning label; he said we should ‘treat conservation management like human health … get the diagnostics right first and then get the treatment right.’  His comments remind me of our approach to Health by Design which you can read about here.  Jim Moseley, past Deputy Secretary of Agriculture and co-Chair of AGree, reminded us that soil is not regulated and so it is through air and water regulations that government will gain its influence; though they will not lead, rather it will take individuals and all are candidates.  We had presentations by U.S. Government officials – Deputy Under Secretary for Research Education and Economics at USDA Ann Bartuska, and Senior Policy Advisor for the Office of Water at U.S. EPA, Ellen Gilinsky, who spoke on U.S. government priorities.  What I found especially refreshing in their comments was support for and emphasis on environmental markets (e.g. nutrient trading) and citizen science (e.g. water quality monitoring) in addition to support for partnerships to scale up field based work to watersheds and to engage global partnerships on nutrient management.  The commitment to innovation came from all sectors, which was the point of this conference.  And we enjoyed a global visual perspective on the importance of soil from Dennis Dimick, Executive Environmental Editor for National Geographic who writes on this subject frequently (link).

Let me close with a comment made to me in a sidebar by a scientist with whom I work regularly who is the past Chief Editor of  two of this nation’s preeminent national agricultural journals, Warren Dick from The Ohio State University. Warren was reflecting on news out of Paris where the Climate Talks are taking place.  While this meeting focused on soils effects on water quality, Warren commented on the importance of soil processes to climate.  This subject is the focus of work planned by Greenleaf with its partners, and perhaps the subject of a future symposium as well – Healthy Soils for Healthy Climate.

My best wishes to all for the advancement of ecosystem health.

Healthy Soils for Healthy Waters and Dennis Dimick of National Geographic

National Geographic’s executive editor for the environment, Dennis Dimick, has come aboard as a keynote speaker for the Nutrient Management and Edge of Field Monitoring Conference held in conjunction with the Healthy Soil for Healthy Waters symposium from December 1-3, 2015 in Memphis, TN.

His post, “Do We Treat Our Soil Like Dirt?” stresses the importance of soil management and health, an issue central to Greenleaf Communities and Healthy Soils for Healthy Waters. Drawing attention to the vital responsibilities of soil, ranging from the growth of the food that feeds us to the quality of the water that sustains us, Dennis puts the priority of healthy soils into perspective. Simply stated, “the future rests on the soil beneath our feet.”

With the Healthy Soils for Healthy Waters symposium taking place the same week as World Soils Day, it seems only fitting that Dennis Dimick, along with a consortium of researchers, conservation professionals and farmers, are coming together to discuss and evaluate best management practices for protecting and preserving Earth’s humble hero – soil.

Healthy Soil for Healthy Water. Sept 15, 2014. Columbus, OH

Monday, September 15, marked the kickoff of the first in a series Healthy Soil for Healthy Water conferences, co-sponsored by Greenleaf Advisors and The Ohio State University. Over 100 representatives of academia, industry, agencies, non-profits and, critically, farmers and agricultural representatives were in attendance for a day of collaborative integration of research and practices. Keynote  speakers Bruce McPheron of OSU and Karl Gebhart from the Ohio EPA were accompanied by presentations from groups like the US EPA, The Nature Conservancy, and NOAA. Coming close on the heels of the Toledo municipal drinking-water system shutdown last month, this event was welcomed as extremely timely and relevant to one of the most pressing environmental issues of the day.

Feedback was that the event was packed with excellent research, tempered with the understanding that there is no easy path to solving the problem of agricultural nutrient pollution in the Great Lakes and Mississippi River watersheds. However, this event was an important step towards the development of true interdisciplinary and collaborative best management practices that will identify the right combination of technologies for the right times and places to have the biggest benefit to farmers, communities, and the environment.

Using an Ancient Approach to Farming to Address Lake Erie’s Modern Problems

FOR IMMEDIATE RELEASE:

Using an Ancient Approach to Farming to Address Lake Erie’s Modern Problems

Columbus, Ohio – August 5, 2014 – Although the phosphorus that contributed to the ban on drinking tap water for most of Toledo’s residents this weekend came from many sources, most experts will point to agricultural runoff as the primary culprit.

Gypsum, or Calcium Sulfate, is a relatively common mineral that has been used in agriculture for thousands of year to improve soil conditions and crop growth; Benjamin Franklin is credited with bringing the practice to America.

Recently, gypsum has come back into focus not only to help farmers support their livelihoods, but also to assist their stewardship of the land and the impact their practices have on the surrounding waterways.

Research led by Dr. Warren Dick, a professor of soil and environmental chemistry with the Ohio State University Department of Environment and Natural Resources, studies gypsum as a tool to directly address the problem of excess phosphorus leaving Ohio’s corn and soybean fields.

This study, now in its second year, applies calcium sulfate directly to fields in the Maumee River watershed, currently the largest single contributor of phosphorus in Lake Erie.  Average reductions of 55% in the concentration of phosphorus in water leaving the farm fields are being achieved.

While gypsum was historically mined, this research makes good use of a modern source, the calcium sulfate that is a byproduct of flue gas desulfurization, a process that removes sulfur from the exhaust of coal-fired power plants.  The beneficial reuse of this gypsum turns an otherwise landfilled material into a valuable and environmentally beneficial soil amendment.

While there is no “silver bullet” for dealing with excess phosphorus in the Great Lakes, the use of gypsum as a soil amendment, combined with other management practices, holds serious potential to help prevent algal blooms in the future.

New Research Identifies Tool to Mitigate Phosphorus

Calcium Sulfate (gypsum) soil amendment reduces SRP loading by over 50%

Data collected from drainage tiles on multiple farms in the Maumee River watershed

Nutrient runoff from agricultural fields is one source of pollution that impacts the integrity of our waterways and the quality of our critical water resources. Fertilizers and animal manures are important sources of the nutrients nitrogen and phosphorus. These help to maintain the productivity of farmland and our nation’s food security in the current agricultural landscape, but they can also impact the environment once they leave the field and enter our lakes and rivers. In the Midwest, phosphorus from farm activities in areas like the Maumee River watershed in Indiana and Ohio contribute to annual “blooms” of algae in Lake Erie that kill wildlife, pollute drinking water with toxins, and disrupt economic growth.

Given the importance of both fruitful and reliable agriculture and the need to safeguard high-quality water resources into the future, research is being conducted into tools that will allow farmers to support their livelihoods while acting as responsible stewards of the lands and waters their farms impact.

Water samples from control and treated fields

Water samples from control and treated fields

One such tool is calcium sulfate (gypsum), and a study underway in Ohio is yielding extremely promising results after just the first use. Gypsum is a naturally occurring mineral that has been recognized for its benefits to agriculture for hundreds of years. It is also a byproduct of flue gas desulfurization (FGD) systems, or the coal-fired power plant “scrubbers” that have been installed in many plants to remove sulfur from their exhaust and reduce acid rain.

Our research, designed and led by Dr. Warren Dick of the Ohio State University, takes this valuable material (which is often disposed in landfills) and reuses it as a beneficial soil amendment that supports environmental, agricultural, and human health priorities.

Even though this research is still underway, it is demonstrating extremely positive results after just the first use. A single application of FGD gypsum on test sites in the Maumee River watershed reduced concentrations of soluble reactive phosphorus (SRP), the most troublesome form in the area waterways, by a significant amount. The gypsum-treated plots showed an average 55% reduction of soluble reactive phosphorus in tile water runoff compared to the untreated plots.

FGD gypsum, as part of a comprehensive nutrient management strategy, holds significant potential to improve water quality in many areas affected by agriculture, from the Great Lakes to the Gulf of Mexico and beyond. In fact, gypsum is a “win-win” in that farmers are already applying it to improve their soil quality and to improve crop yields. This research documents the environmental benefits of gypsum use to complement the economic ones that are increasingly being recognized.

Work to find these types of solutions is critical and is supported by many stakeholders; from farmers to regulators to environmental groups.
