Fertilizer is a material that is added to the soil to supply one or
more elements required for plant growth and productiveness.
The major three elements are nitrogen, potassium and phosphorus),
the secondary elements are calcium, sulfur, magnesium, and other
elements are boron, manganese, iron, zinc, copper and molybdenum.
Fertilizers enhance the natural fertility of the soil or replace
the chemical elements taken from the soil by harvesting, grazing,
leaching or erosion. Organic fertilizers include poperly managed
barnyard manure, compost and green manure. Manure contains nitrogen
and phosphate content. It is sometimes modified with superphosphate
to make it a better balanced fertilizer. Compost, decayed to a
relatively stable, amorphous state, is made from plant materials
mixed with manure and some soil. Green manure is a herbaceous plant
material plowed into the soil that has not undergone decay.
Artificial fertilizers are inorganic fertilizers formulated in
appropriate concentrations and combinations supply three main
nutrients: nitrogen, phosphorus and potassium (N, P and K) for
various crops and growing conditions. N (nitrogen) promotes leaf
growth and forms proteins and chlorophyll. P (phosphorus)
contributes to root, flower and fruit development. K (potassium)
contributes to stem and root growth and the synthesis of proteins.
The common inorganic fertilizers include ammonia (*2% nitrogen),
NPK combinations, urea (*6% nitrogen), superphosphate, mono and
dibasic ammonium phosphates (containing nitrogen and phosphate),
calcium ammonium nitrate, potassium chloride (muriate of potash).
