Potassium Nitrate Synonyms: Saltpeter; niter; Nitric acid, potassium salt CAS No.: 7757-79-1 Molecular Weight: 101.1 Chemical Formula: KNO3 Property: Potassium Nitrate is white crystalline powder or Granular, is highly soluble in water, liquid ammonia and glycerine but insoluble in anhydrous alcohol and diethyl ether.Specification: Chemical Formula KNO3 Purity 99.8% min Potassium Oxide (K2O) 46.0% min Nitrogen (N) 13.5% min Moisture (H2O) 0.1% max Chloride (CI) 0.03% max Insoluble matter (in water) 0.1% max Importance of Potassium in plant growth Potassium is a major plant nutrient and is an essential component of all living cells and metabolic processes. Potassium also helps plants utilise other nutrients more efficiently especially Nitrogen and Phosphorus.Potassium is required by the plant for respiration and transport of photosynthesis products. It also plays a vital role in the activation of many enzymes.Potassium requirement is greatest at the end of the growing season and is important in improving crop quality, fruit size, shape, colour, firmness and shelf life.Potassium deficient plants will tend to grow slowly and develop poor root systems. They are also more prone to stress from extremes of temperature, pests and disease. Benefits of using Potassium Nitrate Potassium Nitrate contains the essential plant elements, nitrogen and potassium and is ideal for use in hydroponics, fertigation, liquid blending and foliar application.Potassium Nitrate contains readily available nitrate nitrogen and readily available potassium.Potassium Nitrate is safe to use on a wide range of fruit, flower and vegetables crops. For application rates, seek professional agronomic advice.
