Red River Valley making progress with the corn harvest

Oct 27, 2022

Manitoba Agriculture's latest crop report shows the provincial harvest is now 95 per cent complete.

Harvest is wrapping up or done in most parts of southern Manitoba.

The corn harvest is most advanced in the Red River Valley with yields running 150 to 200 bushels an acre on average, and between 120 to 150 bushels an acre in the Southwest. The corn harvest was delayed due to wet field in the Interlake and Eastern regions.

The sunflower harvest is in various stages depending on the region. Some farms are done, while others are waiting for the crop to dry down after the recent rains. Sunflower yields have been average to above average, with more plump kernels and fewer empty shells than in 2021. Average yields are reported between 2,000 to 2,300 lbs/acre.

Field Talk Friday | Dr. John Murphy | Root Exudates, Soil Biology, and How Plants Recruit Microbes

Most of us spend our time managing what we can see above ground—plant height, leaf color, stand counts, and yield potential. But the deeper you dig into agronomy, the more you realize that some of the most important processes driving crop performance are happening just millimeters below the surface.

In this episode of Field Talk Friday, Dr. John Murphy continues the soil biology series by diving into one of the most fascinating topics in modern agronomy: root exudates and the role they play in shaping the microbial world around plant roots.

Roots are not passive structures simply pulling nutrients out of the soil. They are active participants in the underground ecosystem. Plants constantly release compounds into the soil—sugars, amino acids, organic acids, and other molecules—that act as both energy sources and signals for soil microbes.
