Where weeds cluster, the soil is telling you something: low calcium, low magnesium, low phosphorus, low pH. Mineral amendments aren’t like fertiliser; they don’t “run out.” They are slow‑release amendments that change soil chemistry over months, not days. Once it’s on the ground, it dissolves into the soil profile. Mineral amendments are cumulative. Every handful you throw is another nudge toward better pH, better calcium, better magnesium, and stronger perennial grasses.

If you were using an online feed balancing calculator based only on hard feed and ignoring pasture, that would be like trying to balance your human diet by focusing super hard on the biscuit you had at morning tea, and ignoring everything else you ate in that day. If we don’t know what’s in the largest part of the diet, we can’t perfectly balance minerals on paper. So instead of chasing perfect numbers, here at Sound Advice we teach owners something far more practical.
