A chemical fertilizer is defined as any inorganic material
of wholly or partially synthetic origin that is added to the soil to sustain
plant growth.
When ammonia is used as the nitrogen source in a
fertilizer, one method of synthetic production requires the use of natural gas
and air. The phosphorus component is made using sulfur, coal, and phosphate
rock. The potassium source comes from potassium chloride, a primary component
of potash.
Understanding NPK (Nitrogen, Phosphorous, and Potash
(Potassium)) ratings on lawn and plant fertilizers is an important part of
deciding whether or not fertilizers are appropriate or even necessary for your
garden and landscaping.
Inorganic fertilizer, also known as mineral or commercial
fertilizer, is fertilizer mined from mineral deposits or manufactured from
synthetic compounds.
Fertilisers make crops grow faster and bigger so that crop
yields are increased. They're minerals, which must first dissolve in water so
that plants can absorb them through their roots. Fertilisers provide plants
with the essential chemical elements needed for growth particularly nitrogen,
phosphorus and potassium.
