Pyrethroid pesticides are effective. Sometimes too effective.

Ancient Barley Took High Road to China, Changed to Summer Crop in Tibet
November 21, 2017 12:31 PM - Washington University in St. Louis

First domesticated 10,000 years ago in the Fertile Crescent of the Middle East, wheat and barley took vastly different routes to China, with barley switching from a winter to both a winter and summer crop during a thousand-year detour along the southern Tibetan Plateau, suggests new research from Washington University in St. Louis.

How carbon farming can help solve climate change
November 21, 2017 08:06 AM - Dalhousie University

Under the 2015 Paris Agreement, nations pledged to keep the average global temperature rise to below 2C above pre-industrial levels and to take efforts to narrow that increase to 1.5C. To meet those goals we must not only stop the increase in our greenhouse gas emissions, we must also draw large amounts of carbon dioxide (CO2) from the atmosphere.

The simplest, most cost effective and environmentally beneficial way to do this is right under our feet. We can farm carbon by storing it in our agricultural soils.

The Hydroponic, Robotic Future of Farming in Greenhouses
November 20, 2017 12:31 PM - Wired

When you think of automation, you probably think of the assembly line, a dramatic dance of robot arms with nary a human laborer in sight. But that’s child’s play. The grandest, most disruptive automation revolution has played out in agriculture. First with horses and plows, and eventually with burly combines—technologies that have made farming exponentially cheaper and more productive. Just consider that in 1790, farmers made up 90 percent of the US workforce. In 2012, it was 1.5 percent, yet America still eats.

Light Green Plants Save Nitrogen Without Sacrificing Photosynthetic Efficiency
November 20, 2017 12:14 PM - Carl R. Woese Institute for Genomic Biology, University of Illinois at Urbana-Champaign

The top leaves of crops absorb far more light than they can use, starving lower leaves of light. Scientists designed plants with light green leaves with hopes of allowing more light to penetrate the crop canopy and increase overall light use efficiency and yield. This strategy was tested in a recent modeling study that found leaves with reduced chlorophyll content do not actually improve canopy-level photosynthesis, but instead, conserve a significant amount of nitrogen that the plant might be able to reinvest to improve light use efficiency and increase yield.
