Profitability Tool for Growers Considering Alternative Rotations in Dryland Systems

For the inland Pacific Northwest, climate change predictions including wetter springs and drier, hotter summers leads to production system uncertainties and risks for dryland, small grain farmers. Annual precipitation is projected to increase by about 5-15% by 2050 except during the summer months where precipitation is projected to decrease, resulting in decreased soil moisture during the late summer months.

Water Use Limitations of Cover Crops in Dryland Cropping

I have seen it work. As a graduate student, I researched cover crops in a California dryland wheat system, comparing a wheat-fallow system to one with a cover crop replacing fallow (McGuire et al., 1998). A wet winter allowed for successful wheat yields in both systems. However, research results suggest that this is often the exception in dryland agriculture. More often, water use by the cover crop reduces the yield of the following cash crop.

What does it take to start a long-term experiment?

“What were they thinking?” It’s a common question asked by agricultural scientists about the design of long-term cropping system experiments. Starting a long-term study is a big investment and having asked those questions ourselves while working with multi-decadal trials, you can imagine how daunting it was to be tasked with setting up a Long-term Agroecological Research and Extension (LTARE) site through the Washington Soil Health Initiative (WaSHI). In 20 years, would people be wondering what the heck we were thinking.

Washington SoilCon and Virtual Engagement

The last two years taught us how to adapt to rapid changes in our daily lives, including the major pivot to remote education. Remote education is nothing new, as WSU has delivered remote video and audio education since the late 1980’s in response to the to the state legislature’s directive for increased accessibility.

Looking to the Future: AgAID Institute

In September 2021, WSU began leadership of a new Agriculture-Artificial Intelligence (AI) research Institute: the AgAID Institute. As the growing population increases food demand, agriculture faces complex challenges related to labor, water scarcity, weather events and climate change. The AgAID Institute is developing AI solutions to help address these pressing challenges and spur the next agricultural revolution with the use of AI.

Why the World Stays Green

The world is green with plants. The world also has thousands of species of plant-eating insects and other organisms. Why don’t all those insects eat all the plants? Why does the world stay green? TCR White, an entomologist from New Zealand, asks this question in a book (White 2005) and a series of fascinating papers. White argues that the answer is not…

How Do Grocery and Meal Kit Deliveries Impact the Carbon Footprint of Our Food?

I explored opportunities to reduce environmental impact related to food preparation and food waste in previous Perspectives on Sustainability articles. However, transportation in the food supply chain is a significant contributor to carbon emissions: all the transportation and miles in between the farm and your plate are part of …
