High Effect Agriculture Grade 99.9% White powder nitrate of potash
It is a potassium salt of nitric acid. Potassium nitrate (KNO3), also known as saltpeter or nitrate of potash, is a white crystalline salt which occurs naturally in nitre or saltpeter. It is a useful fertilizer for normal application and fertigation. Potassium (44% K2O) and nitrogen (13 %) are the constituents of NK fertilizers, which serve as a source of potassium, where extra chloride is not desired.
The agricultural grade of potassium nitrate is freeflowing and non-caking, with a particle size in the range of 1500 to 400 microns.
Potassium nitrate, which is slightly hygroscopic and granulated, can be spread on soil by trucks, fertilizer distributors or by aerial spraying. In a mixed fertilizer, a powdered grade of nitrate of potash does not cake. Potassium nitrate is made by the reaction of potassium chloride with nitric acid as:
The nitrate of potash forms an easily breakable crust on top. It is chemically neutral and its nitrogen and potassium oxide ratio is roughly 1:3. It has been used successfully as a source of nitrogen and potassium for tobacco, tomato, potato, corn, citrus and carnations.
