Details

description2

ULTRAMINO is refined from plant-derived amino acids and four essential trace elements of iron, zinc, copper and boron. This product is rich in nutrients and has high absorption and utilization efficiency. It can comprehensively regulate the growth and development of crop roots, stems, leaves, flowers, and fruits. After use, it can significantly enhance the vitality of crop root systems, increase the photosynthetic efficiency of leaves, and improve the adaptability of crops under adverse conditions such as cold and drought. At the same time, it can effectively improve the quality of pollen, promote strong flowers and fruit, and increase quality and yield.
