GRENA BASE 3.8.8 is an organo-mineral NPK fertiliser particularly suited to vineyards and orchards; through the Grena organic matter, it delivers nitrogen derived from the amino acids contained in both animal-based proteins and feather meal.
Nitrogen’s structural function is enhanced by the presence of phosphorus (natural phosphate rock), enabling the development of strong cell walls, while potassium, in a highly soluble and equally biological form, enables sugar formation in the fruit, for a quality yield.
