First Fall Frost Dates

The first fall frost often marks the end of the growing season, and many garden plants may not survive the freezing temperatures. Learn about some available tools we can use to predict the first fall frost dates around the state.

Urban Stormwater Systems and Leaf Litter

Leaf litter can be a significant source of organic debris to urban stormwater systems during fall rain, which can mean nutrient spikes in the receiving bodies of water. Learn some expert tips for managing leaf litter this fall.

Five Range Management Principles: #4 Residual Forage

Residual forage is the amount of green leaf left after a grazing event. Understanding its importance can help producers capitalize on the symbiotic relationship that occurs when soil health is front and center on rangelands.

Five Range Management Principles: #1 Adaptive Management

Adaptive management is a process that livestock producers can incorporate into their operation to increase operation flexibility and adjust to changing conditions.

Five Range Management Principles: #5 Climate Ready

Understanding your ranching system is critical, and identifying anticipated soil-plant-animal responses during periods of dry, wet, or normal conditions will enable you to develop climate-ready practices. Learn how to get started today!

Grass Tetany: Now Is the Time To Prepare

Grass tetany is a metabolic disorder associated with grazing lush, rapidly growing pastures. Learn the factors that influence its progression along with tips for preventing and managing it in herds.

Selecting a Calving Season Based on Matching Nutritional Needs and Resources

Choosing the calving season is a complex and highly individual decision for each beef cattle producer. A primary consideration in pasture-based cow-calf operations is choosing a calving season that will best match the forage supply to forage demand.

Blue-Green Algae and Livestock

With warmer temperatures, the conditions are right for blue-green algae blooms. Different species of blue-green algae contain various toxins, which can poison livestock, resulting in rapid death.

Nitrates and Livestock Water Quality

Nitrate poisoning is something we think about with forages such as millet, oats, corn, sorghum, sudan, kochia and others that have been fertilized or if there is a drought, but water can also be a contributing factor.

Sweet Clover Poisoning

Hay that contains sweet clover can be an excellent feed as long as the dicoumarol level is known and feeding management is used to prevent poisoning.
