Lyon 56 WG is a solid PK fertilizer designed to support nutrition by providing phosphorus readily assimilable by and immediately available to the plant. Its considerable potassium concentration accompanies the development of the fruit, improving cellular expansion and qualitative features. Lyon 56 WG increases the sugar content and improves colour uniformity. Lyon 56 WG allows activating several enzymatic mechanisms involved in photosynthesis and in the synthesis of amino acids and growth hormones. Lyon 56 WG shifts the plant's metabolism from vegetative to reproductive growth, reducing vegetative growth, with considerable advantages on the quality and quantity of the final production.
