- Quick Lime
- Quick lime is Calcium Oxide (CaO) and should be used with extreme care on soil. It will
react quickly with water to form a calcium hydrate. However, if sufficient water isn't
available, quick lime pulls water from plants, bacteria, fungi and other living organisms,
which can lead to plant death. Quick lime will also react with manures and nitrogen
fertilizers, releasing the nitrogen as a gas before it can be absorbed by the roots.
