4.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.

5.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.
