Green Ravenna offers a line of highly effective biostimulants and specific products for the complete nutrition of plants and for the treatment and prevention of deficiencies of meso and microelements for foliar and/or root application. In particular, the products F1 – F2 – F3 – F4 – F5 – F6, organic matrix fertilizers, are ideal in case of calcium, magnesium, iron, boron deficiencies or in case of abiotic stress (cold, dry, hail). The characteristic that makes these formulations unique is the particular organic matrix that avoids the crystallization of the mineral salts contained, optimal adhesion to plant tissues and rapid absorption of nutritional ingredients for efficient plant development and the treatment of the main deficiency states.

The range is completed by the new biostimulants from the Vitastim^® line: innovative, highly effective products that bring notable benefits to crops in terms of qualitative and quantitative yield, increased resistance to stress and nutrient absorption capacity.
