Knowing the historical last spring frost dates for your area helps growers avoid the risk of frost damage for above-ground vegetation, whether it's for agriculture or horticulture.
Heat Stress in Small Ruminants
The Upper Midwest provides periods of extreme heat during summer and shorter periods of heat stress potential during spring and fall. Are your sheep and goats cool enough in their environment?
Drought and Heat Effects on Corn Production
Nearly every season in South Dakota there are periods of hot, dry weather in at least parts of the state. While we have no control over the weather, producers can prepare for drought stress by using proactive practices.
Estimating Corn Emergence With Growing Degree Days: Data from May 7, 2021
With corn planting well underway in South Dakota, the next step is monitoring its emergence. One of the factors that can speed up or delay corn emergence is air temperature.
Delayed Planting Due to Soil Temperatures?
Although it can be tempting to get a head start with row crops, it's important to be mindful of soil temperatures and the risks associated with planting early.
Soil Temperature for Planting Spring Crops
Soil temperature is an important consideration for deciding when to begin planting spring crops. If producers in South Dakota would like a quick reference for soil temperatures in their area, the SD Mesonet network measures soil temperature at several weather stations throughout the state.
Low Temperature Damage to Corn and Soybean
Temperatures are forecast to reach 32°F or lower in large areas of South Dakota for several nights beginning on May 7, 2020. While a relatively low percentage of planted crops are likely to be emerged at this point in time, producers may still want to evaluate individual fields for crop damage.
2020 Corn Growing Degree Days Update
Spring planting progress of corn in 2020 has been much ahead of a typical year in South Dakota. Crop development, however, seems slow.
Low Temperature Effects on Winter Wheat
Low temperatures during the early morning hours of May 9–11, 2020 may have had detrimental effects on winter wheat in some areas of South Dakota. However, cooler spring temperatures that have slowed the winter wheat development this year may have actually been beneficial to S.D. producers, as later-maturing wheat is not as susceptible to injury from freezing temperatures.
2023 USDA Plant Hardiness Zones
Winter and spring are a great time for planning new garden and landscape designs. Learn how recent updates to the USDA Plant Hardiness Zones may have South Dakota gardeners feeling extra adventurous when selecting new plants for their gardens this season!
