New Soil Microbiologist Aims to Study Plant-microbe Relationships, Improve Crop Growth

By Maddie Johnson

Following an unexpected path from dreams of medical school to agricultural science, soil microbiologist Mark McDonald is eager to improve soil health and crop growth by investigating plant-microbe relationships.

“A lot of people have heard of the human gut microbiome, and they understand if your gut microbiome is changed after taking antibiotics, you’re not going to feel super great,” McDonald said.

He said plants are similar.

Plants need nutrients, and microbes are how they get them, so the relationship is mutually beneficial, he explained.

“If we can understand that relationship better, we can manage our production better to make it easier on the plant and potentially reduce fertilizer costs,” he said. “At the end of the day, I want to be able to go to a field day and tell farmers the biology side of things that could help or hurt plant growth.”

McDonald joined the crop, soil and environmental sciences department last month as an assistant professor. He will conduct research and teach courses as part of the Arkansas Agricultural Experiment Station, the research arm of the University of Arkansas System Division of Agriculture, and the Dale Bumpers College of Agricultural, Food and Life Sciences at the University of Arkansas.

Western Canadian Agriculture: Hard Times Made the World's Best Farmers

Video: Western Canadian Agriculture: Hard Times Made the World's Best Farmers

Western Canadian agriculture produced the most advanced farmers in the world not through abundance but through adversity. The crow rate fell. The wheat price went nowhere. The brown envelopes stopped.

When the subsidies disappeared, the bad farmers left and the good ones stayed. And the ones who stayed could not just grow wheat anymore. They started growing lentils and canola and peas and flax and faba beans. They built crop rotation. They got serious about agronomy because there was no government backstop. That process produced the Western Canadian agriculture Dennis Bulani describes in this clip: the most advanced, most educated farming culture in the world.

His contrast with Iowa corn and soybean farmers is sharp. At a DeKalb farmer meeting in Okoboji, Iowa, he asked what crop rotation they ran. Beans on corn stubble, corn on bean stubble. How do you fertilize? The co-op agronomist handles it. Have you considered other crops? No need. We make so much money on corn and soybeans. Western Canadian agriculture was never allowed that comfort. And now those Iowa farmers are watching soybean markets lock up with China and corn prices slide, and they do not have the agronomy knowledge or the research base to pivot. Western Canadian farmers adapted on a dime because they had done it before.

Dennis also makes the case that Western Canadian agriculture keeps adapting in real time. Low commodity prices over the past year have pushed growers to look seriously at precision spot-spray technology. He knows a neighbor who bought a sprayer with the seeing-eye system and sprayed only 80 out of 320 acres. As a chemical retailer Dennis acknowledges that will affect his sales. He supports it anyway, because if it advances Canadian agriculture and makes farmers money, that is a good outcome.

The lesson Dennis draws from the tale of two farms: continuous improvement is the only durable strategy. When canola was $22 a bushel some growers went to Arizona instead of the Crop Production Show. When the price came down those same growers came back to the research and the discipline. Products do not go on Rack Petroleum's shelves unless they pass a replicated trial first. That is what Western Canadian agriculture built through hard times: farmers who do the work whether the times demand it or not.
