“…-are increasingly used in agriculture (Hong et al, 2007). Dried or fresh seaweeds and liquid extracts to an increasing extent are employed by horticulturists, gardeners, farmers as organic fertilizers and soil conditioners (Zodape, 2001;Rathore et al, 2009;Bulgariu, 2020). Seaweed extracts, which are applied as biostimulants of plant growth have achieved a broader use and market than seaweed and seaweed meal -today there are several algal products and brands available on the market (Khan et al, 2009).…”

In the present study, brown seaweed - Fucus vesiculosus was used as a raw material for the preparation of bio-products for sustainable agriculture. Biosorption was applied to produce fertilizer additives with microelements. F. vesiculosus was enriched with Cu(II) and Zn(II) ions. Biostimulants of plant growth were obtained by seaweed extraction with potassium hydroxide. Different doses of enriched F. vesiculosus (1, 2, 4, 6 mg/per Petri dish) and concentrations of seaweed extract (2.5, 5 and 10%) were examined in germination test on garden cress (Lepidium sativum). The effect of both algal products on the plant length, RGB parameters in leaves and biomass multielement composition was examined. Results showed that the biomass enrichment did not influence plant length and RGB parameters. Taking into account these two parameters, the best results were obtained in the group treated with natural F. vesiculosus (higher than in the control group, treated with distilled water). Enriched F. vesiculosus biofortified garden cress with Cu and Zn. In the case of Fucus extract, 5% concentration increased plant length and the value of RGB parameters when compared with the control group. Also this extract concentration resulted in elevated content of micro- and macroelements in Lepidium sativum. Seaweed extract is recommended for further research as biostimulant of plant growth. Highlights - Fucus vesiculosus is a valuable raw material for agriculture. - Fucus vesiculosus extract can act as biostimulants of plant growth. - Fucus vesiculosus enriched with microelements via biosorption can be used as a fertilizing material providing plants with these nutrients. - Fucus products can biofortify edible plants in essential microelements. - Fucus extracts can enhance plant length and chlorophyll content.

“…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].…”

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.
