(2024-10-15) Nicolai, David; Naeve, Seth
Curt Burns, a farmer and independent crop consultant from South Central Minnesota joins Dave and Seth for a chat about the 2024 crop and soybean harvest. Curt farms in the Steward area and supports other farming operations as an independent crop consultant with C.B. Agronomics in Sibley, Renville, McLeod, Meeker, Nicollet, Kandihohyi Counties.Dave and Seth chat with Curt about the soybean harvest progress and yields. The exceptionally dry and warm fall conditions have left Minnesota soybeans in an unusually dry condition that has led to yield losses for the farmer who is selling overly dry soybeans plus significant field losses due to shattering and harvest loss. Curt discusses his opinions related to yield losses due to the excess spring and summer rainfall and late drought conditions and reports on the soybean yields farmers are seeing in his region. Curt chats with Seth and Dave about variety selection for both corn and soybean. Curt is concerned about other fall activities during this very dry fall. Soil tests may be particularly accurate and will be difficult to pull, and warm and dry soils will lead to N losses for aggressive farmers. Join Dave and Seth for another great Minnesota CropCast with Curt Burns.

Minnesota CropCast - Identity Preserved Soybean Production and Export: Craig Tomera from Grain Millers and Aaron Lorenz, University of Minnesota
(2023-12-19) Nicolai, David; Naeve, Seth
More than 90% of soybeans produced in the US and globally are first processed into soybean meal for animal feed and oil for human consumption and for industrial uses. However, 5-10% of soybeans are consumed more or less directly by humans. Soybeans are used to produce tofu, soy milk, soy sauce, miso, natto, yuba, sprouts, and many other food products. Production of these foods requires specific soybeans with a narrow set of physical and chemical traits. The quality of these food products depends on the quality of the soybeans used.Craig Tomera, an Identity Preserved (IP) Specialist with Grain Millers joins Aaron Lorenz, Soybean Breeder at the University of Minnesota on this week’s Minnesota CropCast. David and Seth learn about IP soybean production in Minnesota from these gentlemen. They chat about yield potential, management and contracting of IP soybeans.
