In farming, some levers never go out of style. One of the biggest is soil pH. If pH drifts too low, fertiliser efficiency drops, nutrient availability tightens, and performance becomes harder to predict. Agricultural lime is the straightforward, time-tested fix: finely ground limestone (calcium carbonate) applied to neutralise acidity and bring soils back into the productive zone. That is the whole point of agricultural lime. It is not a “nice-to-have” add-on. It is the foundation that lets everything else in the nutrient plan work as intended.
