What are fertilizers?
Fertilizers are food for plants: they provide the essential nutrients that they need to grow and thrive.
In addition to carbon, hydrogen and oxygen, which they get from the atmosphere and water, plants need 14 essential nutrients for their growth and health, which fertilizers provide.
These are: nitrogen (N), phosphorus (P), potassium (K), sulphur (S), magnesium (Mg), calcium (Ca), iron (Fe), manganese (Mn), zinc (Zn), copper (Cu), boron (B), molybdenum (Mo), chlorine (Cl), nickel (Ni). Additional elements may be essential to a few plant species, e.g. sodium (Na) and cobalt (Co).
