The trace elements (also called micronutrients) are boron, copper, zinc, iron, manganese and molybdenum.

The mesoelements are calcium, magnesium and sulfur, while the macroelements are nitrogen, phosphorus and potassium.

Each of these has a precise role on the processes of integration, protection and development of crops.

The mesoelements, such as calcium and magnesium, also play a vital role in plants. Calcium has an impact on growth processes, while Magnesium stimulates the formation of chlorophyll and improves photosynthetic activity by increasing the concentration of sugars and improving the color of leaves and fruits.
