Diammonium phosphate(DAP)
DAP is the most widely used phosphate fertilizer among growers today.It is an excellent source of P and nitrogen for plant nutrition.It is highly soluble and thus dissolves quickly in soil to release plant-available phosphate and ammonium. When applied as plant food, it temporarily increases the soil pH, but over a long term the treated ground becomes more acidic than before upon nitrification of the ammonium.A notable property of DAP is the alkaline pH that develops around the dissolving granule.As ammonium is released from dissolving DAP granules, volatile ammonia can be harmful to seedlings and plant roots in immediate proximity.
Formula: (NH4)2HPO4
Total N(%):18
Available phosphoric acid(%): 46
Soluable potash(%): 0
Type of Fertilizer: Compound fertilizers

Monoammonium phosphate(MAP)
MAP has been an important granular fertilizer for many years. It is completely water soluble, generally applied in the granular form and used in the formulation of suspension fertilizers. Granular MAP is applied in concentrated bands beneath the soil surface in proximity of growing roots or in surface bands. It is also commonly applied by spreading across the field and mixing into the surface soil with tillage. With its low pH levels, is best used for high-alkaline soils. It is an ideal starter fertilizer because MAP contains less ammonia-nitrogen than DAP, reducing potential seed damage.
Formula: NH4H2PO4

Available phosphoric acid(%): 52
Soluable potash(%): 0

Ammonium polyphosphate
Ammonium Polyphosphate is a simple fertilizer containing nitrogen and a high level of phosphorous.A liquid solution (10-34-0). The agronomic effectiveness of APP is similar to that of MAP. It is the least expensive form of liquid phosphorous, it is used as an ingredient in liquid blends or as alone as a high P input.
Formula: (NH4)n+2PnO3n+1
Total N(%):10
Available phosphoric acid(%): 34
Soluable potash(%): 0

Potassium nitrate
Potassium nitrate is a chemical compound with the chemical formula KNO3.Common uses of potassium nitrate are in fertilizers.It is a source of potassium and nitrogen, two macronutrients (primary nutrients) essential for plant nutrition and growth. Since healthy growth requires large amounts of nitrogen and potassium, these elements have to be added to the soil in order to achieve healthy growth.
Formula: KNO3
Total N(%):13
Available phosphoric acid(%): 0
Soluable potash(%): 45
Type of Fertilizer: Compound fertilizers

Triple superphosphate
Triple superphosphate (TSP) is of high concentration of water soluble phosphate which can powerfully improve growth of plants or corps, enhance its root develop and the anti-pest ability, according to the practical application of TSP, base fertilizer, seed fertilizer and top dressing will do. It is widely used for the cereals and cash crops as corn, wheat, fruits, vegetabless, cotton, and orghum and so on.
Formula: Ca(H2PO4)2
Total N(%):0
Available phosphoric acid(%): 46
Soluable potash(%): 0
Type of Fertilizer: Phosphate fertilizers

Potassium sulphate
Potassium Sulfate is used to supply potassium. Conventional agriculture, for the most part, supplies potassium with a muriate of potash or what's called 0-0-50. One of the benefits of potassium sulfate is that it's not an extremely high pH fertilizer product.
Formula: K2SO4
Total N(%):0
Available phosphoric acid(%): 0
Soluable potash(%): 50
Type of Fertilizer: Potassium fertilizers

Potassium chloride
Potassium chloride is a metal halide salt composed of potassium and chloride. It is odorless and has a white or colorless vitreous crystal appearance. The solid dissolves readily in water and its solutions have a salt-like taste. The majority of the potassium chloride produced is used for direct application and in blended fertilizers., since the growth of many plants is limited by their potassium intake.
Formula: KCl
Total N(%):0
Available phosphoric acid(%): 0
Soluable potash(%): 60
