The Role of Sodium (Na) in Dairy Cows & Pasture Dairy Insight

Healthy soils, healthy forage, healthy cows – and healthy profits. Sodium plays a vital role in this chain. It’s not just important for cow health and milk production; it also influences the dry matter intake of grass. Over time, applying sodium fertiliser is one of the most effective ways to raise soil sodium levels, which boosts forage sodium content and ensures a more consistent supply of this essential mineral in the diet. Taking a holistic approach to sodium management means better soil, better grass, and better-performing livestock.

In this Dairy Insight we explore the role of sodium for soil health, optimum grass intakes and livestock health.
