What is inoganic manure?

A fertilizer whose compounds are not animal- or plant-based and that nevertheless intends to enrich the soil is what inorganic manure is.

Specifically, manure generally designates animal wastes. But among cultivators, farmers, gardeners and growers, it sometimes is used synonymously with fertilizer. An organic manure therefore originates in animal wastes. An inorganic manure requires the presence of either lab-created substances - such as lab-made urea - or naturally occurring non-organic compounds - such as gypsum, rock phosphate, or sulfur.
