GRENA STAR contains 8% organic nitrogen and is obtained by mixing in laboratory-tested doses of animal proteins with feathermeal, it represents a product with remarkable performances.
Thanks to the presence of free amino acids in particular deriving from keratin contained in the feather, a protein consisting of amino acids, vitamins, and trace elements, which allow plants to withstand environmental stresses and high salt concentrations in soils.
It is a slow-release product: amino acids provide an immediate release of organic nitrogen, while denatured peptides and proteins provide long- term slow release. GRENA STAR shows an effective nitrogen mineralization reaching 50% gradually and in a time of 28 days.
