Minerals and organic materials present in soil are responsible for regulatory activity of cell organelles. Micronutrients such as zinc, boron, copper, iron, manganese, molybdenum and chlorine are readily absorbed and found in lower concentrations in plant tissues. Micronutrients reduce ion toxicity, preserve water balance, improve mineral uptake and assimilation, modify various gas exchange traits and reduce oxidative stress in plants. Plants contain sufficient micronutrients that possess greater tolerance capacity towards abiotic stress. The response of micronutrient application to various abiotic stresses depends on the crop, growth stage and concentration of the nutrient solution. This chapter explains the significance of micronutrients in crop production and their ability against the abiotic stress in plants.

“…Chemical fertilizers and pesticides were an effective short-term solution, but their long-term effects are starting to show, e.g., decrease in soil quality, and accumulation of toxic metals in the soil [1,2]. Currently, there is a tendency to search for a new generation of agro-products manufactured from raw materials of biological origin [3][4][5]. Algal products (e.g., extracts) that improve the uptake of minerals from the soil and increase the resistance of plants to biotic and abiotic stress can contribute to the reduction of chemicals used in agriculture [6][7][8].…”

“…Enzyme-assisted extraction also produces a post-extraction residue, which has not been used on a large scale so far. Considering the idea of bio-based economy and sustainable development, this residue, depending on chemical composition, can be valorized into many value-added products such as sorbents of metal ions, soil improvers, and feed additives [4,5]. Therefore, through this study, we used an up-andcoming and environmentally responsible extraction method to fully exploit both the resulting extract and the resulting residue, with the goal of creating biostimulants and biosorbents through a zero-waste biorefinery approach.…”

The underexploited biomass of red seaweed Solieria chordalis (C.Agardh) J.Agardh 1842 represents a potential source for biotechnological development. Extracts obtained from S. chordalis by enzyme-assisted extraction using Protamex® and Neutrase® were evaluated as potential biostimulants of plant growth. Additionally, this alga, as well as post-extraction residues, were examined as biosorbents of metal ions. The biostimulant properties of different concentrations of algal extracts (20, 40, 60, 80, 100%) were tested in vitro on radish seeds. Chlorophyll content, plant weight, and height were measured for each experimental group. For all tested concentrations, the plants demonstrated higher chlorophyll content and were higher and heavier than the control group, showing that enzyme extracts could be used as efficient biostimulants. The biosorption properties of seaweed and post-extraction residues were tested on Cr(III) ions for different experimental conditions—pH, initial metal ion concentration, and biosorbent dosage. The maximum biosorption capacity of S. chordalis was 48.1 mg/g, for the post-extraction residue obtained with Protamex®, 47.6 mg/g, and Neutrase®, 50.5 mg/g. The binding of Cr(III) ions to the surface of biosorbents was confirmed by FT-IR analysis. Good biosorption properties of tested materials can be used in the production of novel components of fertilizers or biosorbents for wastewater treatment. In this paper, it was shown that waste biomass of S. chordalis can be turned into valuable bio-products using environmental-friendly technologies.
