GRENA ULTRA MICRO was developed for distribution on soils not subject to subsequent tillage, such as vineyards and grassed orchards. Its micro-pellet formulation allows natural organic nitrogen to be readily available for plant nutrition thanks to a fast mineralisation time, which also makes it ideal for last-minute fertilisation. GRENA ULTRA MICRO meets the need for a lower environmental impact, with a significant reduction in dosage made possible by the natural presence of amino acids and humic and fulvic acids, which facilitate the assimilation of nutrients.
GRENA ULTRA MICRO spreads evenly with low visual impact and works excellently with transplanting machines.
The presence of Calcium enhances the organoleptic quality of plant tissues, as well as increasing the freshness and shelf life of the fruit.
In vineyards, it promotes the development of regular internodes and a marked increase in the final Babo degree.
Also important is the presence of Silicon (SiO2), which adds thickness to the skin and resistance to insects.
