GRENA BASE 3.8.8 S

GRENA BASE 3.8.8 is an organo-mineral fertilizer NPK particularly suitable for vineyards and orchards.
Through the Grena organic substance conveys nitrogen derived from amino acids of animal origin and from feathermeal.
The function of nitrogen is accentuated by the presence of phosphorus (natural phosphorites) allowing the development of robust cell walls. Potassium, in very soluble form and always of biological derivation, allows the formation of sugars in the fruit, culminating in a quality production.
