Climate Change Will Cut Corn Yields by a Quarter by 2030, NASA Says

Global corn yields could sink by nearly a quarter by 2030 as climate change wreaks havoc on traditional weather patterns.

That’s according to a new international study from groups including the National Aeronautics and Space Administration and the International Institute for Applied Systems Analysis. Rising temperatures and shifts in rainfall will make it harder to grow the crop — a staple in global livestock rations — in areas like the Americas, west Africa and China. And the production cuts are occurring sooner than expected versus past studies.

“Even under optimistic climate change scenarios, where societies enact ambitious efforts to limit global temperature rise, global agriculture is facing a new climate reality,” lead author Jonas Jaegermeyr said in a statement. “And with the interconnectedness of the global food system, impacts in even one region’s breadbasket will be felt worldwide.”

Video: Our Own On-Farm Research Is the Best Source - Managing White Mold in Northeast Nebraska

If you assumed Nebraska was too hot and dry for white mold to be a problem in soybeans, think again.

This week we're featuring Galen Samuelson, a farmer and dealer from Wakefield, Nebraska, who knows all too well how devastating white mold can be.

"We don't have it consistently every year, but with our temperature and humidity, it can hurt us quite bad," Samuelson says. Looking for alternatives, he explains, "What I like about Heads Up is that it's non-harmful to the beneficial fungal colonies in the soil." Galen has been using Heads Up for several years now, after first hearing about it through a small ad in a regional newspaper. Watch below to hear about his journey.

When asked to write about Samuelson Seed, Galen said the following:

"Samuelson Seed is a 4th-generation, family-based company. It started with my grandfather, and I'm now starting to pass the torch to my son, Caleb."

"In the early 1990s, I started working with a company whose focus was on plant and soil health before those benefits were widely known. I've continued to keep plant and soil health the main focus in our farming operation decisions."
