BIOSTIMULANT ACTION
The challenge of producing quality grapes.
Today, producing high-quality grapes represents a growing challenge due to the extreme weather conditions we are exposed to daily. These climate changes negatively impact the quality of our products. However, it is possible to enhance grapevine health and grape quality by increasing the organic matter content and integrating mineral elements into the soil.
GRENA GRAN VIGNETO 7.5.12S is an organo-mineral fertilizer that offers an excellent solution for vineyard fertilization. This product combines mineral fertilizers and high-quality organic matrices, such as proteins, amino acids, humic acids, and fulvic acids, obtained through thermal hydrolysis. These components promote root development and improve nutrient absorption from both the fertilizer and the soil. The microelements contained within play a catalytic role in plant physiological processes, helping to correct any deficiencies. In this way, it is possible to achieve superior quality grape production despite challenging environmental conditions.
GRENA GRAN VIGNETO 7.5.12S is not approved for organic farming because it is composed of organic nitrogen and ammonium sulfate, offering a fast-acting effect, especially during the vegetative growth revival stage. If you wish to apply a product that further enriches the soil at the time of harvest, consider GRENA LIFE 4.6.10S, a highly balanced and organic product that provides a gradual and corrective action of its internal natural minerals.
Another alternative, in case of a specific need for organic nitrogen in the soil—such as in low-fertility soils or those with a high presence of rock fragments (skeletal soils)—could be the application of GRENA TURF 8.3.3. This product is 100% organic and derived from meat proteins, with added bone meal to provide natural phosphorus and potassium, creating a complete product capable of supporting the vineyard post-harvest and preparing it for a true vegetative revival.
IDROGRENA Universal is an organic liquid biostimulant that promotes the absorption of nutrients and microorganisms without increasing soil salinity. In the context of the vineyard, it stimulates grapevine root growth and enhances their immune response, counteracting various types of stress and increasing the Brix degree of the grapes, which translates into a higher quality wine. It is compatible with most plant protection products used in viticulture.
ENERGY is essential for grapevines before flowering and during fruit set, as it supports flower fertility and berry size, thereby contributing to a more abundant and higher quality harvest.
IDRO IRON Grena +Fe 2% is an organic liquid fertilizer containing chelated iron, which is fundamental for photosynthesis in grapevine leaves and for the quality of the final wine, improving absorption and offering anti-stress effects, particularly useful under iron deficiency conditions.
MATURA combines polyamines with potassium, enhancing the quality and taste of the berries during ripening. This is particularly advantageous for winegrowers looking to optimize the grape ripening process, in both conventional and organic farming.
