Abstrakt
The article discusses the possibility of the use of algal products, obtained by different methods – extraction (traditional solvent extraction, supercritical fluid extraction, extraction assisted by microwave) and homogenization, in the cultivation of plants. Algal extracts were discussed for their use as potential plant growth biostimulants and the homogenates as formulations for seed treatment. The work is focused on the possibility of using primarily macroalgae from the Baltic Sea basin (in many seaside resorts constitute a waste due to eutrophication) as raw material for the extraction/homogenization. Examples of the research (laboratory – germination tests and field trials) on the impact of algal preparations on the plant growth were presented. Literature data indicate that the algae based products increase the content of micro-, macroelements, chlorophyll in the cultivated plants, as well as their length and weight. Therefore, in the future, they may complement the range of products available on the market.
