News & Insights

  • Building Better Pastures through Optimal Soil Nutrition
    Productive pastures do not happen by chance. They are built from the ground up, starting with a thoughtful approach to soil nutrition. When soil health is managed with intention, the result is higher-quality forage, improved livestock performance, and a more resilient grazing system that pays dividends year after year. Read more
  • Broadleaf Weed Control: A Proven Tool for Rangeland Management
    GRASS INTO GAINS  WITH ALLIGARE RANGE & PASTURE Broadleaf weed control on rangelands has been a cornerstone of effective land management for decades. Since the introduction of 2,4-D in the 1940s, land managers have had access to a powerful tool that selectively targets broadleaf plants while leaving grasses intact. This revolutionary herbicide made it possible to reshape and enhance pastureland without disturbing the valuable grass species that serve as the foundation of forage systems. Over the years, many new active ingredients have been introduced to the market and this practice has become standard among livestock producers, conservationists, and landowners seeking to improve the productivity, safety, and ecological health of their rangelands. The benefits are broad and well-documented: increased forage production, delayed or prevented brush encroachment, reduced presence of poisonous plants, and support for land restoration efforts.Read more
  • Optimizing Grazing Efficiency through Strategic Prickly Pear Management
    Opuntia, more commonly known as prickly pear, is a well-recognized symbol of the Southwest, but for land managers and livestock producers, it often represents a persistent challenge. While several species are native to the region, invasive species originating from Central America and the West Indies have also become established. Whether growing horizontally across the ground or standing vertically at heights exceeding six feet, prickly pear can significantly disrupt grazing operations. Its dense structure and sharp spines limit access to desirable forage, reduce pasture productivity, and deter cattle from grazing effectively.Read more
  • Fall Herbicide Applications: The Key to Reducing Spring Weed Pressure
    Successful weed and brush control doesn't start in the spring. It starts now, with proactive fall herbicide applications.Read more
