Romasse BZn is an organic liquid fertiliser of plant origin with a consistent content of aminoacids (obtained through enzymatic hydrolysis) and a mineral component represented by two of the most essential trace elements in crop cycle: boron and zinc. The synergistic effect of the organic fraction with the microelements enhances photosynthesis and plant metabolism, improves flowering and fruit setting, prevents potential micronutrient deficiencies and helps crops overcome stress of abiotic origin.
