\nFertilizers are substances used to provide essential nutrients to plants, primarily nitrogen (N), phosphorus (P), and potassium (K).
\nA) Ammonium nitrate (NH\u2084NO\u2083) is a common nitrogen fertilizer.
\nB) Ammonium sulphide ((NH\u2084)\u2082S) contains nitrogen and sulfur, but it is highly unstable and decomposes easily to ammonia and hydrogen sulfide gas. Due to its instability and potential toxicity (hydrogen sulfide), it is not used as a common agricultural fertilizer.
\nC) Ammonium phosphate (e.g., (NH\u2084)\u2082HPO\u2084 or NH\u2084H\u2082PO\u2084) are common fertilizers (like DAP and MAP) providing both nitrogen and phosphorus.
\nD) Ammonium sulphate ((NH\u2084)\u2082SO\u2084) is a common fertilizer providing nitrogen and sulfur.
\nTherefore, Ammonium sulphide is not used as a fertilizer.
\n<\/section>\n
\nCommon fertilizers contain essential plant nutrients, primarily nitrogen, phosphorus, and potassium, often in the form of stable salts. Ammonium compounds are often used as sources of nitrogen, but their suitability as fertilizers depends on their stability and chemical properties in soil.
\n<\/section>\n
\nWhile ammonium sulphide contains nitrogen and sulfur, its instability makes it unsuitable for agricultural application. It is more relevant in laboratory chemistry or specific industrial processes rather than widespread use as a soil nutrient source.
