The main minerals are consumed by plants in very small quantities, measured in thousandths or even hundreds of thousand shares of a percent, but are essential for their development. Each of these micronutrients plays its own role, but in some cases, they can replace each other.

Boron treats some diseases, increases the amount of the ovaries, preventing them from falling off, enhances the development of the reproductive organs, increases the number of vitamins in fruits, and promotes better development of vascular influences the activity of several enzymes. Boron increases the yield of sugar beet, the sugar content in the roots, the harvest of peas, broad beans, harvest flax fiber, flax seeds, and fiber quality.

Manganese is indispensable in the process of photosynthesis, the formation of ascorbic acid is found in many enzymes, and increases the yield of sugar beet and sugar in it. Copper activates protein synthesis, provides drought and frost resistance of plants, resistance to fungal and viral diseases, is part of a series of enzymes. In general, positive effect on the protein and carbohydrate metabolism of plants. Zinc is a component of many enzymes involved in the processes of fertilization, respiration, synthesis of proteins and carbohydrates. Molybdenum is important in the processes of assimilation of nitrogen from the air, is part of an enzyme involved in the restoration of nitrate-nitrogen to ammonia, stimulates the nitrogen-fixing bacteria, such as nodule, and free-living. Increases the yield of corn, peas, and beans, vetch, fodder lupine, clover, and meadow hay, a positive effect on the yield of cauliflower.

Cobalt is essential for the life of root nodule bacteria. Required for legumes, which are in need of cobalt in the process of nitrogen fixation.
