NPK/NK fertilizers are high-performance compound nitrogen-phosphate-potassium fertilizers including all nutrients required for plant growth. Production form – granules. NPK is produced by neutralizing of phosphoric and sulphur acid mixture with ammonia, with addition of potassium chloride and UAN solution, followed by drying and granulation.
The product is non-hydroscopic and non-caking. All salts, which are the components of this fertilizer, are water-soluble. A variety of grades provides a precise application of fertilizer for any specified crop and soil.
