What is Lime? | GraymontThe lime cycle consists of first burning of limestone to form quicklime. Hydrated lime can then be produced by adding water to the quicklime. At this point, carbon dioxide in the atmosphere or from industrial processes react with hydrated lime to convert it back to limestone. This cycle is called the lime …

Soil Management - University of HawaiiWhen absorbed by plants, ammonium and nitrate are incorporated into plant cells as organic, or living, forms of nitrogen. When plants die, microorganisms break down, or decompose, dead plant cells. During the decomposition about plant matter, organic nitrogen is once again converted to inorganic ammonium and released into the soil.
