Seven Springs Farm Supply Aragonite
Best natural calcium source for organic gardeners seeking soil mineral balance.
This marine-sourced calcium is the gold standard for growers who need to balance soil pH without the magnesium spikes found in traditional dolomitic lime. It’s a cleaner, more precise way to feed your soil, though you’ll need to manage the application carefully to ensure even coverage across your beds.
