UPDATE - Potential for spring freeze injury to wheat on April 3, 2020
Many areas of Kansas experienced freezing temperatures on April 3, 2020. How cold and for how long are both factors that help determine the potential for injury to wheat. Read about other factors in this article and what our specialists say about this latest cold snap.
Another round of cold weather brings a risk of freeze injury to Kansas wheat
Another round of very cold temperatures have put much of the Kansas wheat crop at risk for freeze injury. What portions of the state have the greatest potential for damage? What areas may have escaped with little impact?
Spring freeze effects on winter canola
Several factors determine the extent of freeze damage to winter canola during the spring. It is most tolerant in the early stages of growth and most vulnerable in the flowering and pod-filling stages. Read more about the risk of damage to this year's crop.
Preliminary wheat injury assessment from the April 13-17 freeze events in Kansas
Since some time has passed since the freeze events from mid-April, varying degrees of injury have appeared in Kansas wheat fields. Which regions were impacted the most and how severe does the damage appear at this time?
Options and management strategies for freeze-damaged wheat
Producers whose wheat crop has suffered severe freeze damage have some difficult decisions to make. This article discusses some options and management tips for freeze damaged wheat.
Assessing and managing freeze-damaged alfalfa
Alfalfa fields in portions of Kansas are showing the effects of freezing temperatures over that last few weeks. What should farmers look for when assessing their alfalfa stands for damage? What are the best management options?
Sorghum development and potential freeze injury
Grain sorghum maturity is significantly ahead of last year and close to the 5-year average. What effect did the early September cold snap have on crop development? Will the remaining sorghum reach maturity before the first freeze? Read more here from K-State Agronomy.
Risk of freeze injury to Kansas wheat for April 20-22, 2021
Several factors interact to influence the degree of freeze damage to wheat. Some of these factors are wheat growth stage, air temps, duration of cold weather, soil temps, snow cover, landscape position, and crop residue. Where does the KS wheat crop stand after this latest bout of cold weather?
Injury symptoms from freeze damage to wheat
The recent cold temperatures experienced this week were enough to cause freeze damage to Kansas wheat. The actual freeze damage will be region-specific depending on crop growth stage, minimum temperatures, and other factors. Learn more in this article.
2022 Kansas Wheat: Crop Conditions and Risk of Freeze Injury
The 2021-22 winter wheat crop conditions has deteriorated considerably during the last few months, and the latest USDA-NASS report suggests that only around 30% of the Kansas wheat crop is in good or excellent. The increased water demand led by greater fall biomass production was, unfortunately, met with below average precipitation during the late fall and winter – especially in western Kansas, leading the crop to experience early signs of drought stress in that portion of the state. While the crop in central Kansas is still mostly not undergoing severe drought stress, the recent increase in biomass as the crop goes into reproductive development will be accompanied by an increase in crop water demand; thus, more precipitation will be needed shortly to avoid yield losses due to drought.
Injury symptoms from freeze damage to wheat: what to look for?
The recent cold temperatures experienced during 31 March – 14 April 2022 were enough to cause freeze damage to winter wheat in parts of Kansas. The actual freeze damage will be region-specific depending on crop growth stage and minimum temperatures (some regions had a worst combination of temperatures and crop growth stage) and, within a region, field specific owing to many individual aspects such as crop density, residue level, etc.
