The modern agricultural sector faces the challenge of addressing the needs of the fast-growing global population. This process should be both high-yielding and sustainable, without creating risks for the environment and human health. Therefore, natural products are gaining attention in the production of safe and nutritious food. In a systematic effort to develop affordable and effective biostimulants, we examined the impact of botanical extracts on the growth and physiological parameters of radish plants under field conditions. Ultrasound-assisted extraction, mechanical homogenization, and water were used for the production of potential plant-based biostimulants. Foliar applications of the bio-products, developed and used in our study, have led to an increase in the examined parameters (total yield, dry weight, photosynthetic pigments, vitamin C, nitrates, and micro- and macroelements). A decrease in the total phenolic compounds content was also noted, as well as a varied impact on the steam volatile compounds, fatty acids, sterol, and glucosinolates composition. The most beneficial effects on radish, in terms of physiological and biochemical properties, were found in groups treated with extracts based on the common dandelion, valerian, and giant goldenrod. This innovative approach presented in our study could provide a valuable tool for sustainable horticultural production.

Nutraceuticals and functional foods are gaining more attention amongst consumers interested in nutritious food. The consumption of foodstuffs with a high content of phytochemicals has been proven to provide various health benefits. The application of biostimulants is a potential strategy to fortify cultivated plants with beneficial bioactive compounds. Nevertheless, it has not yet been established whether the proposed higher plants (St. John’s wort, giant goldenrod, common dandelion, red clover, nettle, and valerian) are appropriate for the production of potential bio-products enhancing the nutritional value of white cabbage. Therefore, this research examines the impact of botanical extracts on the growth and nutritional quality of cabbage grown under field conditions. Two extraction methods were used for the production of water-based bio-products, namely: ultrasound-assisted extraction and mechanical homogenisation. Bio-products were applied as foliar sprays to evaluate their impact on total yield, dry weight, photosynthetic pigments, polyphenols, antioxidant activity, vitamin C, nitrates, micro- and macroelements, volatile compounds, fatty acids, sterols, and sugars. Botanical extracts showed different effects on the examined parameters. The best results in terms of physiological and biochemical properties of cabbage were obtained for extracts from common dandelion, valerian, nettle, and giant goldenrod. When enriched with nutrients, vegetables can constitute a valuable component of functional food.

The use of higher plants for the production of plant growth biostimulants is receiving increased attention among scientists, farmers, investors, consumers and regulators. The aim of the present study was to examine the possibility of converting plants commonly occurring in Europe (St. John’s wort, giant goldenrod, common dandelion, red clover, nettle, valerian) into valuable and easy to use bio-products. The biostimulating activity of botanical extracts and their effect on the chemical composition of celeriac were identified. Plant-based extracts, obtained by ultrasound-assisted extraction and mechanical homogenisation, were tested in field trials. It was found that the obtained formulations increased the total yield of leaves rosettes and roots, the dry weight of leaves rosettes and roots, the content of chlorophyll a + b and carotenoids, the greenness index of leaves, the content of vitamin C in leaves and roots. They mostly decreased the content of polyphenols and antioxidant activities in leaves but increased them in roots and conversely affected the nitrates content. Extracts showed a varied impact on the content of micro and macroelements, as well as the composition of volatile compounds and fatty acids in the celeriac biomass. Due to the modulatory properties of the tested products, they may be used successfully in sustainable horticulture.

This research presents the possibility of using innovative botanical extracts as biostimulants of plant growth to improve plant nutritional value, growth, and development. It is important to increase agricultural production but this process should be carried out in a sustainable way, without causing risks for both the environment and consumers. For this reason, we have focused on the use of 14 natural raw materials and ultrasound assisted extraction for the production of biostimulants. Results proved that higher plants can be used to obtain valuable products for the application in modern horticulture and agriculture. For instance, extract based on Urtica dioica L. showed the highest biostimulatory properties: in the group sprayed with 0.1% extract cabbage seedlings were longer by 31%, while with 1.0% extract of Polygonum aviculare L. roots were longer by 72% than in the control group treated with water. Extracts based on Equisetum arvense L. (0.5%) and Urtica dioica L. (leaf) (0.1%) increased the fresh weight of sprouts by 113% and 112%, respectively. The highest root weight was observed in groups treated with Equisetum arvense L. (0.5%), Polygonum aviculare L. (0.5%), and Urtica dioica L. (leaf) (2.5%)—heavier by 207%, 206%, and 205%, respectively. Most of biostimulants increased the content of pigments involved in photosynthesis (e.g. 156% more chlorophyll for 0.1% Hypericum perforatum L. extract), decreased the content of polyphenols (e.g. 47% less for 2.5% Trifolium pretense extract), and showed a varied impact on antioxidant activity. There is an increasing interest in botanical extracts due to their high content of biologically active compounds and wide variety of application possibilities.

Arthrospira (Spirulina) platensis was tested for biosorption properties. Preliminary experiments concerning biosorption kinetics were performed on Cr(III) ions. Equilibrium of biosorption was tested for Cr(III), Mn(II) and Mg(II) ions, since these elements are crucial for animals with metabolic disorders. In our study, Spirulina was proposed as a feed additive for animals suffering from diseases characterized by insulin dysregulation, abnormal adipose distribution and a high risk for laminitis. Maximum biosorption capacity of A. platensis, determined from Langmuir equation, was 45.2 for Cr(III), 44.3 for Mn(II) and 42.0 mg/g for Mg(II) ions. Biosorption of Mg(II) ions by microalga has never been studied so far. Finally, the raw and enriched microalgal biomass was examined by ICP-OES to determine its multielamental analysis before and after biosorption, FTIR to indicate functional groups that participated in biosorption and SEM-EDX to illustrate the binding of metal ions on the surface of algal biomass. ICP-OES showed that the content of elements significantly increased in the enriched A. platensis. FTIR spectroscopy evidenced that biosorption of metal ions was mainly due to carboxylate groups present on the microalgal cell wall. SEM analysis clearly showed that biosorption occurred. Arthrospira platensis turned out to be a good biosorbent of metal ions.

The aim of this study was to investigate the potential of using natural raw materials that have not been used for the production of biostimulants of plant growth. These products can effectively contribute to overcome the challenge posed by the increasing demand for food. Ultrasound assisted extraction (UAE) was chosen to prepare innovative biostimulants. The expected outcome of this research was to generate products that show beneficial effects on white head cabbage growth, development, and nutritional quality. The results proved that higher plants (mugwort, calendula, purple coneflower, chamomile, basil, giant goldenrod, comfrey, dandelion, and valerian) can be successfully used for the production of biostimulants. For example, products based on common dandelion showed the highest biostimulating activity. In a group treated with 2.5% flower extract, cabbage shoots were 37% longer, whereas in a group treated with 0.5% leaves extract, roots were longer by 76% as compared with a control group treated with water. Biostimulants based on common mugwort (at a dose of 0.5%) and common dandelion (root) (at a dose of 1.0%) increased the mass of cabbage shoots and roots by 106% and 246%, respectively. The majority of biostimulants increased the content of photosynthetic pigments (chlorophyll and carotenoids) and decreased the content of polyphenols. Botanical extracts also showed varied impact on the antioxidant activity of cabbage. Taking into account the benefits for a wide scope of applications, it is expected that the utilization of these types of products should increase in the future. These products can play a key role in sustainable agriculture.

In the present paper, products obtained from a blue-green microalga Spirulina platensis filtrate (applied for seed soaking and for foliar spray) and homogenate (used for seed coating) were tested in the cultivation of radish. Their effect on length, wet mass, multielemental composition and the greenness index of the radish leaves was examined. Multi-elemental analyses of the algal products, and radish were also performed using inductively coupled plasma-optical emission spectrometry (ICP-OES). The best soaking time, concentrations of filtrate and doses of homogenate were established. The longest and heaviest plants were observed for homogenate applied at a dose of 300 µL per 1.5 g of seeds and 15% of filtrate applied as foliar spray. The highest chlorophyll content was found in the group treated with 100 µL of homogenate and 5% of filtrate. In the case of soaking time, the longest plants were in the group where seeds were soaked for 6 h, but the heaviest and greenest were after soaking for 48 h. The applied algal products increased the content of elements in seedlings. Obtained results proved that algal extracts have high potential to be applied in modern horticulture and agriculture. The use of Spirulina-based products is consistent with the idea of sustainable agriculture that could help to ensure production of sufficient human food to meet the needs of rising population and protection of the environment.

The yield, chemical composition and antioxidant activity of eight genotypes (‘Krezus’, ‘Turkus’, ‘Kozak’, ‘Szmaragd’, ‘Lukullus’, ‘Herkules’, ‘Ambrozja’, ‘Moravan’) of garden dill (Anethum graveolens L.) biomass was estimated. Field experiments were conducted in 2011-2013 in Poland. The crop lasted 44 days and plants were collected at the 4-5 true leaf stage (a bunch harvest). The highest marketable yield was obtained for ‘Krezus’ and ‘Szmaragd’ cultivars (1.18 kg·m-2), while the lowest for ‘Herkules’ (0.53 kg·m-2). The dry matter of leaves ranged from 15.17% (‘Ambrozja’) to 19.27% (‘Krezus’). The study also proved that the genotype influenced the content of chlorophylls a+b, e.g. 1.10 g·kg-1 (‘Moravan’) and 0.78 g·kg-1 (‘Lukullus’), respectively carotenoids: 21.43 mg·100 g-1 (‘Moravan’) and 11.78 mg·100 g-1 (‘Szmaragd’). The content of nitrates (371.48 mg·kg-1 ‘Lukullus’ - 110 mg·kg-1 ‘Szmaragd’), K (11.30% ‘Moravan’ - 5.37% ‘Kozak’), Ca (2.06% ‘Turkus’ - 1.77% ‘Kozak’), and oils (99.13% ‘Lukullus’ - 93.82% ‘Ambrozja’) was also varied. In most cases the content of Mg, P, sugars and ascorbic acid was on similar level. The antioxidant activity was significantly different between tested groups (12.22 µM·g-1 ‘Turkus’ - 6.27 µM·g-1 ‘Krezus’). The presented research proved that the genotype of garden dill affects yield and chemical composition of plants. ********* In press - Online First.

The research was conducted to evaluate the possibility of using algae enriched with Cr(III) ions as a feed additive for horses. As a sorbent, macroalgaCladophora glomeratawas chosen. The results of the kinetic and equilibrium experiments on biosorption of Cr(III) ions are presented. The pseudo-second order model was used for the description of kinetics. Equilibrium of biosorption process was described by Langmuir model. The effect of biosorbent dose: 0.1–1.0 g·L-1, initial metal ions concentration: 100–300 mg·L-1and pH: 3–5 on the biosorption capacity in a batch system was evaluated. These factors played a significant role in affecting the biosorption capacity of biosorbent and the rate constant. Optimal pH for biosorption was 5, biosorbent dose 0.1 g·L-1, initial concentration of Cr(III) ions 300 mg·L-1. The maximum biosorption capacity determined from Langmuir equation was 107.5 mg·g-1(forCS1.0 g·L-1, pH 5). The experiments were also performed in a column system and they showed that almost 100% of Cr(III) ions were absorbed after 200 minutes. The FTIR and SEM-EDX technique confirmed binding of Cr(III) ions by the algal biomass. Due to very good biosorption properties,Cladophora glomeratacan be considered as a carrier of microelement ions in animal feeding.

In the present work, dry plant biomass that is commonly used in horses feeding: alfalfa, chopped grass pellets and chopped grass was used as a biosorbent of microelement ions: Cr(III), Zn(II), Cu(II) and Mn(II). Biosorption process was used to potentially enhance supplementation of minerals in horses diet. In order to characterize the biosorption properties of the examined biomass, preliminary experiments (kinetics and equilibrium studies) were conducted with Cr(III) ions. The effect of pH and initial metal ions concentration (C0) on the biosorption capacity (q) was investigated. On this basis, the best experimental conditions were chosen (pH 5, CS 1.0 g/L (biomass content), C0 200 mg/L). For them, biosorption of Mn(II), Zn(II), Cu(II) ions was carried out in a periodic and continuous system (biosorption column). Equilibrium of the biosorption was described using Langmuir equation. The mineral composition of the raw and enriched biomass was also examined using ICP-OES, as well as SEM-EDX technique. In general, the best biosorption properties were observed for alfalfa. The maximum biosorption capacity for Zn(II) was 27.5 mg/g, for Cu(II)—38.5 mg/g, for Mn(II)—13.6 mg/g and for Cr(III)—33.2 mg/g. Therefore, the biomass of enriched alfalfa can be recommended as a feed supplement for horses.

Increasing knowledge on nutrition and plant biotechnology has changed the concepts of agriculture, food, and its impact on health. The numerous scientific research and publications have shown that algae provide health benefits to the people. Seaweeds, due to the beneficial biochemical composition, have a great potential to be used as components of food aimed at increasing its nutritional value. Algal cells possess a wide diversity of biologically active metabolites, e.g., proteins, vitamins, minerals, polysaccharides, amino acids, fatty acids, lipids and could be used in the development of pharmaceuticals and also essential compounds for human nutrition. They could be used as an antioxidant, anti-inflammatory, anticoagulant, antimicrobial, antibacterial, antiviral, antifungal, anticancer, antiobesity, antidiabetic, hypercholesterolemic, and antihypertensive nutraceuticals. The nutritional algae value differs from various species, geographic areas, seasons, and water conditions are taken into account. Currently, the algal products have become familiar to people and the prevention of disease is better understood. The number of healthcare pharmaceuticals from algae is still in the development stage and new functions are being investigated.

Baltic seaweeds were used to obtain aqueous extracts (E) through changing initial pH of deionised water added to algal biomass (EpH3·H2O, EpH7·H2O, and EpH10·H2O) and through changing pH of the mixture of algae and deionised water (EpH3, EpH7, and EpH10). Algal extracts were characterized in terms of the concentration of polyphenols and micro- and macroelements. The highest concentration of polyphenols was determined in extract EpH3 and the lowest in extract EpH10·H2O. It was found that the obtained extracts had similar concentrations of elements (except EpH3). The phytotoxicity of algal extracts (0.5, 2.5, and 10%) was examined in the germination tests onLepidium sativum. No phytotoxic effects were observed. It was found that they had beneficial effects on the cultivated plants (length and weight). The best biostimulant effect was observed in the groups treated with EpH3 (2.5%), EpH7 (2.5%), and EpH7 (10%). The dry weight of plants was similar in all the groups. Algal extract also improved the multielemental composition of plant. The greatest concentration of total chlorophyll in plants was obtained by using extract EpH10·H2O, 0.5%. These results proved that algal extracts have high potential to be applied in cultivation of plants.

We explored two methods for obtaining aqueous extracts: boiling and soaking of Baltic seaweeds (EB and ES, resp.). Algal extracts were characterized in terms of polyphenols, micro- and macroelements, lipids content, and antibacterial properties. The utilitarian properties were examined in the germination tests onLepidium sativumfor three extract dilutions (0.5, 2.5, and 10%). It was found that the extracts were similar in micro- and macroelement concentrations. Water was proved to be a good solvent to extract phenolic compounds. The algal extract produced by soaking biomass did not show inhibitory effect onEscherichia coliandStaphylococcus aureus. Only the boiled extract had an inhibitory activity againstE. coli. Germination tests revealed a positive influence of the bioproducts on the cultivated plants. In the group treated with 10% EB, plants were 13% longer than in the control group; the content of elements B, Mo, Zn, and Na in the group treated with 10% ES was higher by 76%, 48%, 31%, and 59% than in the control group, respectively; the content of chlorophyll was 2.5 times higher in 0.5% ES than in the control group. Extracts showed the slight impact on the morphology of plants.

Spirulina has been studied due to its commercial importance as a source of essential amino acids, protein, vitamins, fatty acids etc. Most of the culture systems in use today are open ponds. The new approach proposed in this paper is to use the geothermal water as a medium for microalgae cultivation. Poland has beneficial conditions for wide geothermal use, as one of the environmentally friendly and sustainable renewable energy sources. In the planned research, geothermal water could be used to prepare microalgal culture medium, to heat greenhouses with bioreactors used for the growth of Spirulina, to dry the obtained biomass, as well as to heat the ground in foil tunnels. Using geothermal water gives the possibility to produce algae in open ponds covered with greenhouses and to cultivate plants during winter. The obtained algae can be used for the production of algal bio-products (e.g. homogenates), having the potential application in plant cultivation.
