The amendments in the ACTIFORT range are based on calcium and magnesium carbonates of natural origin, and contain the Vivafert® complex. This speciality provides soluble sugars, amino acids and bio-available trace elements, all of which help to stimulate biological activity in the soil and make nutrients available to plants. Their amending effect plays an important role in soil conditioning, helping to maintain soil pH at an optimum level for the assimilation of mineral elements by plants and soil life.
