Easy Usage Guidance and Effects

Direction for use

Fertilizer: Used in fertilizers, as a source of nitrogen and potassium-two of the macro nutrients for plants.


Oxidizer:  Used in black powder rocket motors, but also in combination with other fuels like sugars in "rocket candy".

                           It was used for treating asthma as well as arthritis.

                           It combats high blood pressure and was used as a hypertensive.



Function& Benefits

Nitrogen and Potassium are both essential for higher yield and better quality of crops.


Nitrogen as nitrate anion (NO3-), the most available form of nitrogen for plant uptake.


Potassium Nitrate is an ammonium-free source of nitrogen, hence safe for use even at high temperatures.


Potassium supply is essential to prevent the development of plant diseases.


Potassium can enhance the plant’s ability to withstand extreme conditions.


Potassium helps improving quality parameters of Fruit size, lager dimensions, better uniformity Fruit looks, better color, minimized color blemishes or unusual markings of mechanical injuries or any sign of disease nutritional values, higher content of protein, oil, vitamin C, etc. Organoleptic features, enhanced flavor and aroma, longer shelf life.

Fertilizer for tobacco has fast effective, easy to absorb, to promote early seedling development, and increase in tobacco production, while it also played an important role to  improve the quality of tobacco.
