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).
