Description

7-7-7 is a balanced NPK organo-mineral fertilizer with high versatility of use. The granular formulation ensures easy and uniform distribution with commonly used machinery. It can be adopted for a wide range of crops due to the completeness of the nutrient complex. The nitrogen supply is made available through constant and progressive release thanks to fractionation into its components: ammonium, urea, and organic nitrogen.


The phosphorus-potassium component is highly soluble and assimilable, allowing it to meet the nutritional needs of many herbaceous and woody crops. Sulfur (sulfur dioxide) plays a fundamental role in improving the quality of productions by participating in the biochemical processes of protein synthesis, as a constituent of vitamins and enzymes. It stimulates the process of photosynthesis and nutrient translocation, enhancing the resistance and consistency of plant tissues, and elevating the organoleptic qualities of the final product.


Organic carbon serves a protective function for the mineral components, improving their assimilation by crops.


The presence of sulfur in synergy with nitrogen enhances the absorption process of these two elements and plays an important role in enhancing production quality. It also participates in biochemical processes of protein synthesis, acting as a constituent of vitamins and enzymes, stimulating the photosynthesis process, providing greater consistency and resistance to plant tissues, and enhancing the organoleptic characteristics of the final product.
