Fertility: More Than Just Growth
Fertiliser is not merely a growth accelerator — it underpins sustainable, high-performing pastures. In Australian soils, which are often nutrient-poor and highly weathered, well-designed fertility programs are critical for persistence, animal health, and overall farm profitability.
Matching Fertility to Pasture Composition
At UMS, we align fertiliser strategies with pasture genetics, enterprise type, and seasonal conditions. Legume-rich pastures require adequate phosphorus and molybdenum to support nitrogen fixation, while grass-dominant systems respond strongly to nitrogen. Deep-rooted species such as lucerne benefit from potassium for persistence and structural integrity, while high-sugar grasses respond well to split nitrogen applications, improving feed quality without overfertilising.
Timing and Application
Starter fertiliser at sowing drives early establishment. Autumn applications optimise feed production during the critical winter period, while spring nitrogen can boost growth and animal performance. Overuse, however, can reduce legume content and increase costs. UMS provides guidance on nutrient timing and rates based on soil tests, pasture composition, and seasonal growth patterns.
Trace Elements and Animal Health
Copper, cobalt, selenium, and zinc influence both pasture and animal health. Inadequate levels can limit productivity and affect livestock performance. UMS incorporates trace element considerations into its advice, helping growers maintain a healthy and balanced system.
Efficiency and Sustainability
Variable rate application, split dosing, and legume integration help optimise nutrient use efficiency, reduce environmental impact, and lower input costs. In Tasmania, for example, integrating white clover into ryegrass pastures allowed some dairy farms to reduce urea use by 30% without compromising milk solids production.
Integrated Fertility Strategy UMS views fertiliser as part of a holistic pasture strategy. When combined with high-performing seed and careful soil management, it underpins pastures that are productive, resilient, and sustainable. This integrated approach ensures that each investment in seed and nutrients delivers measurable returns for both the paddock and the farm enterprise.
