Rock Dust Could Help Fight Climate Change and Boost Crop Yields

A new Anglo-French study suggests that spreading crushed volcanic rock on farmland could help remove carbon dioxide from the atmosphere — and potentially boost crop yields. However, its effectiveness depends heavily on local soil conditions.

Researchers from Rothamsted Research (UK), INRAE (France), and the UK’s National Oceanography Centre tested basalt rock dust — a quarrying by-product — on two soil types: sandy and silty clay. In pot trials, they applied the dust at two rates (equivalent to 80 and 160 tonnes per hectare) and monitored changes in soil chemistry and ryegrass growth.

The method, known as enhanced weathering, accelerates the natural breakdown of silicate rocks, a process that draws CO₂ from the air and locks it into the soil. Supporters see it as a promising climate solution with co-benefits for soil health,

AI Already has an Opinion About You. Is it Positive?

Before rejoining the family seed business in 2003, I worked in PR, researching clients online. Today, AI tools like ChatGPT are replacing traditional search engines, with Google seeing its first monthly query decline on Safari.

E-commerce, Opportunities and (Many) Risks for the Seed Sector

E-commerce—buying and selling products online via websites, apps, or marketplaces—has grown rapidly since 2000, offering opportunities but also risks for sectors like the seed industry, with transactions spanning B2B, B2C, and peer-to-peer across countries.

Orange Blossom Special: The Rust Stops Here

For a new wheat cultivar like Orange Blossom CL+, OFSS handles the initial seed increase, enabling limited quantities to be made available to certified seed growers ahead of full commercialization.

This early distribution accelerates the time from cross to commercial grain, in part by overlapping foundation seed production with later-stage field trials—a shift that has reduced commercialization

A Launchpad for New Varieties

wheat

Oklahoma State University’s latest Clearfield wheat release, Orange Blossom CL+, enters the landscape with a familiar genetic base — and a few new traits aimed squarely at today’s rust-related risks. The release follows years of internal development and field trials. The variety features a familiar genetic backbone and brings a combination of higher yield, early stripe rust resistance, and test weight comparable to its predecessor, Doublestop CL Plus.

Lessons from Expanding into South America

Expanding globally brings opportunities and challenges, from regulations to payment complexities. Agronomix has focused on South America, offering Spanish-optimized software and support to help plant breeding programs succeed, despite occasional payment uncertainties.

ITRC 2025 Spotlights Turfgrass Climate Adaptation

The 2025 International Turfgrass Research Conference in Karuizawa, Japan, highlighted innovation, sustainability, and climate resilience in the turfgrass industry through hundreds of expert presentations.

Is it Time to Reimagine Cover Crops?

Cover crops are now a key solution for soil health, nutrient retention, and sustainability. Iowa State’s Seed Science Center is exploring perennial cover crops that stay in the field year-round, reducing disturbance and inputs while boosting farm resilience.

Why Weird Corn Matters

A proposed USDA consolidation threatens the Maize Genetics Cooperation Stock Center, home to 100,000 mutant corn lines critical to seed innovation. Researchers warn that relocating the collection from the University of Illinois could disrupt decades of progress in crop genetics.

The Built-In Chill Factor

University of Missouri researchers have discovered that soybeans use a stress survival strategy called differential transpiration to protect flowers and pods during heat and drought. This physiological trait prioritizes cooling of reproductive tissues and could be enhanced through breeding or gene editing. As climate change intensifies, scientists and seed companies are exploring how to integrate this mechanism into elite soybean varieties to preserve yield under extreme weather.
