Dairy systems demand balanced mineral nutrition for both plant and animal health. A biologically active soil supports higher nutrient density and reduces animal metabolic stress. Base fertility comes from composted manures and calcium-rich ameliorants. Worm Granule 531 encourages microbial mineralisation and nutrient uptake. Using DSA, foliar programs fine-tune key nutrients like sulphur, magnesium, and trace elements to enhance milk solids and herd health.
