Each week a few of our agronomists give a report on how the fields are looking in Kansas, Nebraska, Colorado and Iowa. This report, called Radio Servi-Tech, is available online.

We’ll have more updates each week!
Parts of the Midwest are experiencing heavy rains and waterlogged fields.
Here’s a story from Ag Professional about how the crops fair in heavy rains.
Corn and soybean survival in waterlogged soils
Over the last five days, some areas in South Dakota, Iowa and other states have received more than 6 inches of rainfall leading to ponded or flooded areas in fields. Water saturated or waterlogged soils lack enough oxygen for root respiration and many wonder, “How long can corn and soybeans plants at early growth stages survive in these waterlogged soils?” There are many factors that lead to this question’s answer says Nathan Mueller, South Dakota State University Extension Agronomist.
“We know that the crop growth stage, variety/hybrid, duration of ponding/saturation, soil type, soil/air temperature, and other factors can affect the survival of corn and soybean plants under these waterlogged conditions,” Mueller said. “Unfortunately other factors reduce plant population related to flooding including crusting, plants covered in sediment or buried under residue, and increase in seed/seedling diseases like damping-off in soybean.”
Currently, the crop growth stages of most corn and soybean range from germination to V3 and germination to V1, respectively. At these early growth stages of germination, emergence and early vegetative, Mueller says both corn and soybean plants are negatively impacted quite quickly by waterlogged conditions.
“Crops that are not completely submerged have some limited capacity for diffusion of oxygen to occur from the shoot to the root, which increase survival time,” he said. “Oxygen is needed by plant cells for growth and development including germination.”
Corn planting is currently underway in Kansas, Colorado, Nebraska and Iowa. This year our agronomists are taking videos of the process.
Here’s our video.
It is spring time…right?
We wanted to share some photos with you that were taken over the past couple of weeks.
