As we face unusual weather patterns with hotter temperatures and limited rainfall, it becomes crucial to make informed decisions for effective pasture risk management. Here are some key points to remember during challenging conditions:
- Take Half/Leave Half: Grazing systems should aim to maintain residual leaf cover in pastures, promoting continual photosynthesis and energy capture. It is recommended to avoid grazing below four inches in height for tall fescue and orchard grass.
- Rest Period: Cool-season grasses grow slowly during the summer months, emphasizing the importance of providing adequate rest periods for plant recovery. Rest periods of 30 to 60 days are common, depending on temperature and precipitation.
- Rule of Thirds: When mowing, follow the "rule of thirds," cutting only one-third of the total leaf area to avoid early decline of pasture, increased weed pressure, and decreased soil moisture and productivity.
- Nitrate Accumulation and Prussic Acid Buildup: Prolonged dry weather can lead to nitrate accumulation in plants and prussic acid buildup in specific forage species. Limit intake rates and introduce livestock gradually to new forage. Forage testing and cautious management protocols can help mitigate risks.
- Mowing Height: Pay attention to mowing height, as cutting or grazing grass too low can negatively impact productivity. Aim for 8-10 inches in height before regrazing.
By implementing these practices, farmers can mitigate risks associated with drought, promote healthy pasture growth, and maintain sustainable forage management.
