Types of fertilizer

The main fertilizer (Fertilizer) used

(A) Nitrogen Fertilizer

The nitrous fertilizer industry produces synthetic ammonia, nitric acid, ammonium nitrate and urea. Synthetic ammonia and nitric acid are mainly used to produce ammonium nitrate and urea fertilizers. These fertilizers are the main nitrogen man element which is a percentage (%)

Liquid ammonia	82% N2
Ammonium chloride	25% N2
Ammonium Sulphate	19.92% N2
Calcium Ammonium Nitrate	25% N2
Urea	46 - 46.5% N2
Ammonium Nitrate	32 - 35% N2
Sodium Nitrite	15 - 16%N2
Aquaris Ammonia	16.5 - 20.5 % N2

(B) Phosphatic Fertilizer

Phosphatic fertilizers are commonly used as superphosphate and triple superphosphate. Phosphoric acid is used in the same way or with other phosphatic fertilizers.

Fertilizer plays a role in plant growth.

Single Super Phosphate	14 - 21% P2O5
Tripple Super Phosphate	40 - 50%
Di-Calcium Phosphate	27.4%

(C) Potassic Fertilizer

Potash fertilizers are chemicals that contain potassium (K+) in absorbable forms, namely muriate of potash (KCI) and sulphate of potash (K2S04). These are water-soluble and hence easily available to plants.
