What are the names of the elements in ordinary fertilizer?

Answer 1

Many different elements and compounds are used in varying proportions as plant fertilizer.

The 6 main elements used are: nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), and sulfur (S)

Seven others elements are also used as "micronutrients": boron (B), chlorine (Cl), copper (Cu), iron (Fe), manganese (Mn), molybdenum (Mo), and zinc (Zn).

A compound that is commonly used in agriculture as a "high-nitrogen" fertilizer, is ammonium nitrate (NH4NO3).

Answer 2

The most important element is the one the plant is most in need of. Since plants take up large quantities of nitrogen and potassium they are often the most needed but phosphorus is very often less available than crops need, hence NPK. But in different circumstances any of the other elements may be the most restricting.

Answer 3

Nitrogen, phosphorus and potassium are the elements in ordinary fertilizer.

Specifically, an ordinary fertilizer can be used to enrich the soil and improve the survival chances of many plants. It is not deemed a specialty fertilizer such as one that specifically treats citrus trees. It may be familiarly known as an "N-P-K" - the three letters representing the respective chemical symbols - fertilizer because of the predominance of the above-mentioned three elements.

Nitrogen, phosphorus and potassium usually are not the only elements in a fertilizer. Their ratio to other elements nevertheless can be dominant since - along with calcium, magnesium and sulfur - they represent three of the six elements of which healthy plants and soil have most need. Other elements which will be called micronutrients for their need in lesser quantities may include boron, chlorine, cobalt, iron, manganese, molybdenum, nickel, and zinc.
