Potassium Nitrate (Technical Grade)

Potassium Nitrate for Fertigation and Industry

Potassium Nitrate is a white, water-soluble salt that supplies two major plant nutrients at once: nitrogen and potassium. Potassium nitrate contains about 13% nitrogen and 46% potassium oxide (K₂O), which is why it is sold as 13-0-46.

We stock technical grade Potassium Nitrate under the Chemivit brand, supplied by Lianyungang Chemivit International Co., Ltd. of China. It comes in 25 kg bags with a five-year shelf life. Wisdo Merchants Chemical Division delivers it across Kenya and East Africa from Industrial Area, Nairobi.

Features and Benefits of Potassium Nitrate

• Two nutrients in one: Supplies nitrate nitrogen and potassium together.
• Chloride-free: Suits chloride-sensitive crops such as tobacco, potatoes and many fruits.
• Fully water soluble: Ideal for drip irrigation and foliar feeding.
• Fast-acting nitrogen: Nitrate nitrogen is taken up by plants immediately.
• Long shelf life: Five years from manufacture when stored correctly.

Applications of Potassium Nitrate

Agriculture and Horticulture

Growers use it in fertigation, hydroponics and foliar sprays, especially for flowers, vegetables and fruit during flowering and fruit filling. Fertiliser blenders also use it in water-soluble NPK mixes. Browse our agricultural chemicals.

Industrial Uses

Industries use potassium nitrate in heat-treatment salt baths for metals, in glass manufacturing and in some food-curing processes, which require food-grade material. See our metal treatment chemicals.

Safety and Handling

• Oxidiser: It may intensify fire. Keep it away from fuels, oils, sawdust and other combustible materials.
