VIVAR TEK 1 O PIU’ is a product made up of low and medium molecular weight amino acids deriving from the hydrolysis of proteins of animal origin, characterized by total and rapid assimilation on the leaves. It is not comparable to a generic nitrogen fertilizer as it consists of a stable mixture of complex structures (peptides, proteins, amino acids) which are the basis of the complex phytoregulatory functions of plants and a high concentration of organic nitrogen. VIVAR TEK 1 O PIU’ allows an increase in photosynthetic activity favoring a balanced vegetative-productive development; an overcoming of stress of various kinds; an increase in biological and biochemical processes such as to determine the emission of new shoots and new leaves which is followed by a considerable stimulus to flowering and consequently excellent productions in terms of quality and quantity.
