The long term study updated the previous evaluation of glyphosate with cancer incidence, and is part of the Agricultural Health Study (AHS), a large and important project that tracks the health of agricultural workers and their families.
Led by AHS principal investigator Laura Beane Freeman, the study results state that among 54,251 applicators studied, 44,932 (82.8 percent) used glyphosate. "Glyphosate was not statistically significantly associated with cancer at any site," the study said. For the full story, click here.
University of Saskatchewan biology professor Christy Morrissey stated in a press release, “Studies on the risks of neonicotinoids have often focused on bees that have been experiencing population declines. However, it is not just bees that are being affected by these insecticides.” | READ MORE
The young scientist spent a few days this past summer in the heart of Canada’s wheat belt working on the problem of aluminum toxicity in acidic soil. It’s a problem that affects wheat growers in many parts of the world although not in Saskatchewan, home to the CLS, where Kopittke spent an intense 36 hours earlier this year.
Globally, it is estimated that acid soils result in more than US$129 billion in lost production annually. In Western Australia, farmers lose A$1.5 billion annually because the aluminum in the soil destroys the root system, killing the plant. For the full story, click here.
“Most plants are sensitive to extreme changes in soil temperature,” said Samuel Haruna, a researcher at Middle Tennessee State University. “You don’t want it to change too quickly because the plants can’t cope with it.”
Many factors influence the ability of soil to buffer against temperature changes. For example, when soil is compacted the soil temperature can change quickly. That’s because soil particles transfer temperatures much faster when they are squished together. When farmers drag heavy machinery over the soil, the soil particles compact. Soil temperature is also affected by moisture: more moisture keeps soils from heating too quickly.
Research has shown that both cover crops and perennial biofuel crops can relieve soil compaction. Cover crops are generally planted between cash crops such as corn and soybeans to protect the bare soil. They shade the soil and help reduce soil water evaporation. Their roots also add organic matter to the soil and prevent soil erosion. This also keeps the soil spongy, helping it retain water.
But Haruna wanted to know if perennial biofuel and cover crops could also help soils protect themselves from fluctuating temperatures. Haruna and a team of researchers grew several types of cover and perennial biofuel crops in the field. Afterwards, they tested the soils in the lab for their ability to regulate temperature.
“I was amazed at the results,” Haruna said. He found both perennial biofuel and cover crops help soils shield against extreme temperatures. They do this by slowing down how quickly temperatures spread through the soil. Their roots break up the soil, preventing soil molecules from clumping together and heating or cooling quickly. The roots of both crops also add organic matter to the soil, which helps regulate temperature.
Additionally, perennial biofuel and cover crops help the soil retain moisture. “Water generally has a high ability to buffer against temperature changes,” said Haruna. “So if soil has a high water content it has a greater ability to protect the soil.”
Although Haruna advocates for more use of cover crops, he said it’s not always easy to incorporate them into farms. “These crops require more work, more financial investment, and more knowledge,” he said. “But they can do much for soil health.” Including, as Haruna’s research shows, shielding plants from extreme temperature changes.
“Climate change can cause temperature fluctuations, and if not curtailed, may affect crop productivity in the future,” he said. “And we need to buffer against these extreme changes within the soil.”
Haruna hopes to take his research from the lab and into the field. He says a field experiment will help him and his team collect more data and flesh out his findings

In an effort to shine a light on the current status of herbicide resistance in Canada, Top Crop Manager (TCM) has launched the Herbicide Use Survey!
As an industry leader providing up-to-date information and research, TCM is looking to gather input from producers across the country in order to develop a more thorough understanding of the state of herbicide resistance in Canada.
TCM’s Herbicide Use Survey will offer participants the ability to help tell the story of these important crop protection tools by having farmers like you share how herbicides are being used.
The survey takes less than 10 minutes to complete, and will ask details like soil and farm acreage, types of weeds being targeted, as well as management practices. All submissions will remain anonymous.
Those who complete the survey will be entered into a random draw for a $500 visa card! Complete the survey here.
The Herbicide Use Survey ends December 8th. Results will be collected and presented at the 2018 Herbicide Resistance Summit in Saskatoon, Sask., on February 27 and 28.

The Temporary Foreign Worker (TFW) Program's Agriculture Stream supports Canada's economy by permitting employers to hire temporary foreign workers for positions in agriculture and agri-food when qualified Canadians and permanent residents are not available.
Employment and Social Development Canada, in collaboration with Agriculture and Agri-food Canada, recently announced that the Government is looking for research on the primary agricultural sector to support a review of the TFW Program's Primary Agriculture Stream.
Canadians with an interest in primary agriculture, which is work that is performed within the boundaries of a farm, nursery or greenhouse, are being asked to share available, objective and evidence-based research on the primary agricultural sector.
Submitted research can be on a number of issues related to primary agriculture and will inform future changes to the program, including methods for determining wages and labour shortages. For instance, research on why certain populations such as women, youth and Indigenous people are underrepresented in the agriculture industry could help in the development of future recruitment and retention efforts.
Research can be submitted through the call-out on the Consulting with Canadians web page. The call-out will be open until November 24, 2017.
"Our government embraces science and research and we know that evidence is the key to making informed decisions. High-quality research and feedback from Canadians will play an integral role during the Primary Agriculture Review as we continue ensuring the TFW Program works for workers, for employers and for the Canadian economy," said the honourable Patty Hajdu, Minister of Employment, Workforce Development and Labour in a press release.
Organized by Bayer, together with the two Belgian young farmers associations Groene Kring and Fédération des Jeunes Agriculteurs, the event provided an opportunity for delegates to work on concrete solutions to one of humanity's greatest challenges: How to feed a growing world population in a sustainable manner.
At the Youth-Ag Summit, delegates, including four from Canada, worked throughout the week in groups of 10 to develop their ideas, before pitching to a jury of experts and the audience. The jury and the audience then selected the winners on the basis of criteria such as feasibility, innovativeness and creativity:
- Third place went to "Imperfect Picks", a group who was assigned to work on SDG 12: Responsible Consumption and Production. These delegates impressed with their cartoon campaign to promote "ugly fruits" to children, and enable a broader cultural shift towards accepting food that appears blemished but is still of good quality. They won €3,000 to further develop and implement their project.
- Second place went to "Seeds of Change", a group of delegates focusing on SDG 4: Quality Education. They will use their prize of €5,000 to fund a project aimed at promoting agriculture in schools through young agricultural champions, in order to bridge the disconnect between people who consume, and people who produce food.
- Finally, first place was awarded to the group "AGRIKUA" ("kua" being the Swahili word for "grow"), whose project focuses on promoting Gender Equality (SDG 5) in the agricultural sector. Their plan to create an online professional platform for young Kenyan women seeking opportunities in agriculture impressed the jury and audience alike, and they took home the grand prize of €10,000. On top of this funding, the AGRIKUA delegates will also receive dedicated training and coaching to help make the project a reality. They will also be invited back to Europe to present their project to a relevant industry platform.
"I'm very fortunate to have been part of such an amazing team. The outcome we achieved is because of the collaboration and commitment of our group to make a real impact in addressing food security," said Hayward. "Within 24 hours our lives changed. Since my teammates and I arrived at home, various groups have expressed their interest in our project."
Hayward wasn't the only Canadian to garner attention at the Youth Ag-Summit. In fact, all of the top teams had representation from Canada—the only country in attendance to do so.
"We are extremely proud of our Canadian delegates," said Al Driver, president and CEO, Bayer Crop Science. "These four delegates used their diverse experience and backgrounds to find tangible solutions to addressing food security. They should all be proud in the manner they represented their country to the world."
Speaking about this year's crop of winners, Fleur Wilkins, Head of strategic messaging and executive communications for Bayer Crop Science and member of the jury, said, "We were blown away by the level of creativity, intelligence, and diligence shown by each of the delegate groups in the final projects they presented. Bayer is thrilled to be funding three of these for future development, but we are convinced that all of this year's Youth Ag-Summit delegates will continue to champion and contribute to a more sustainable food system."
As well as working in groups to develop their projects, delegates spent the week hearing from world-renowned speakers and partner organisations, who inspired them to each commit to doing "Three Little Things" in their everyday life to foster greater food security.
They also paid a visit to the EU Committee of the Regions, and met with Members of the EU Parliament Tom Vandenkendelaere and Richard Ashworth to discuss agricultural policy. Another highlight of the week was a visit to Hof ten Bosch, a Bayer ForwardFarm nestled in the heart of the Belgian countryside.

Soil is a vital natural resource and the foundation of agricultural production. The many benefits of a healthy soil are important - underpinning the long-term sustainability of the farm operation, our agri-food sector and our environment.
What is a healthy agricultural soil? Essentially it refers to a soil's ability to support crop growth without becoming degraded or otherwise harming the environment.
While a soil can be degraded through particular practices, the good news is that many best management practices (BMPs) can build back and safeguard soil health.
The draft strategy builds on the vision, goals, objectives and concepts presented in the 2016 'Sustaining Ontario's Agricultural Soils: Towards a Shared Vision' discussion document.
It also builds on the extensive soil health efforts of agricultural organizations and OMAFRA. It was developed in collaboration with the agricultural sector, and it reflects feedback received during public engagement on the discussion document, from farmers, Indigenous participants and other interested groups and individuals.
OMAFRA would like to hear your thoughts and feedback on the draft strategy. Your input will help guide the development of a final Soil Health and Conservation Strategy for Ontario which will be released in spring 2018.

“Soybeans and rye complement each other really well,” says Mike Ostlie, agronomist at the North Dakota State University’s Carrington Research Extension Center. “Rye adds a lot of things to soybeans that really complete a good production system. You can use rye as a weed-management tool because it suppresses weeds that are becoming increasingly resistant to glyphosate.” READ MORE
