GENERAL
DESCRIPTION
|
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 (82% nitrogen), NPK combinations, urea (46% nitrogen), superphosphate,
mono and dibasic ammonium phosphates (containing nitrogen and phosphate),
calcium ammonium nitrate, potassium chloride (muriate of potash).
