In the present paper, the novel environmentally friendly micronutrient fertilizer biocomponents produced via biosorption and based on the biomass of seaweed were introduced. The utilitarian properties of new preparations were examined in germination tests on Lepidium sativum. The application of micronutrient biocomponents with zinc resulted in the higher mass of plant and higher content of zinc in comparison with the untreated group and reference materials, leading to the biofortification of plants with this micronutrient (a more than 20-fold increase in zinc level was obtained). It was observed that the dosage of zinc influenced plant mass and element content of plants. Statistically significant correlations between zinc and other microand macronutrients were observed. Also, a strong positive correlation (0.55) between zinc and plant mass was found.
The micronutrient biocomponents produced via the biosorption process can constitute an alternative tool for micronutrient fertilization as preparations characterized by high bioavailability of nutrients and high biodegradability constituting an “eco-friendly” method for micronutrient biofortification of plants.
