What is inoganic manure?

Inorganic manures are those which do not contain carbon compounds but supply essential mineral elements to the soil. They may be of natural or synthetic origin.

Some examples of inorganic manures are:

* Mineral fertilizers: These are industrially produced fertilizers that contain high concentrations of essential nutrients such as nitrogen, phosphorus, and potassium. Examples include ammonium nitrate, urea, superphosphate, and muriate of potash.

* Limestone: This is a natural mineral that is used to correct soil acidity and provide calcium and magnesium.

* Gypsum: This is a natural mineral that is used to improve soil structure and provide calcium and sulfur.

* Rock phosphate: This is a natural mineral that is used to provide phosphorus.

* Slag: This is a waste product from metal smelting that is used to provide calcium, magnesium, and other nutrients.

Inorganic manures are often used in conjunction with organic manures to provide a balanced supply of nutrients to the soil.
