Keynote: The influence of bio-fertilizers enriched with beneficial bacteria and filamentous fungi on the growth and rhizosphere microbiology of ‘Marmolada’ strawberry plants in container cultivation
Time : 09:30-10:15
The experiment in stoneware pots was established in the spring of 2018 in four replications in the Experimental Field of the Warsaw University of Life Sciences in Skierniewice. The objects studied were strawberry plants of the cultivar ‘Marmolada’.
The experiment was conducted in stoneware pots with a diameter of 40 cm filled with about 270 litres of arable soil with a pH of 6.2, to each of which three seedlings of the Frigo A+ type (15-18 mm) strawberry plants were planted out at the beginning of May. Each combination consisted of six replications (stoneware pots). The experiment was established in a random block design with a total of 13 experimental combinations, including beneficial microorganisms and filamentous fungi, and a no-treatment (zero) control. In addition, the ‘Marmolada’ strawberry plants were divided into two experimental groups: in one of them the plants were grown in optimal irrigation conditions (100% of the water dose), and in the other, from mid-June, under drought stress (50% of the water dose). In both groups, the same fertilization was applied. The experiment included the following experimental combinations: 1. Control – plants not fertilized; 2. Standard NPK fertilization; 3. Control with the addition of filamentous fungi (Aspergillus niger and Paecilomyces lilacinus); 4. Control – with the addition of beneficial Bacillus bacteria (Bacillus sp., Bacillus amyloliquefaciens and Paenibacillus polymyxa); 5. Standard NPK + filamentous fungi; 6. Standard NPK + beneficial bacteria; 7. 100% Polifoska 6 + beneficial bacteria; 8. 100% Urea + filamentous fungi; 9. 100% Polifoska 6 enriched with beneficial bacteria; 10. 100% Fos Dar 40 enriched with beneficial bacteria; 11. 60% Urea enriched with filamentous fungi; 12. 60% Polifoska 6 enriched with beneficial bacteria; 13. Fos Dar 40 in a 60% dose enriched with three strains of beneficial bacteria.
In 2018, yielding was not assessed because all inflorescences were removed. The amounts of minerals (macro- and micronutrients) were determined in strawberry leaves. In the autumn, runners were collected for assessment, where the number, fresh weight, length, the number of runner plants and their fresh weight were determined. The results of the first year of the study showed that filamentous fungi and beneficial bacteria applied together with mineral fertilizers tested on strawberry plants (Urea, Polifoska 6, Fos Dar 40) increased their biological activity. This was particularly evident in the development of the aboveground parts of strawberry plants (runners and runner plants, and the concentration of some minerals, macro- and microelements, in the leaves).
The amount of water supplied to the strawberry plants fertilized with various mineral fertilizers enriched with beneficial bacteria and fungi had a greater impact on the growth characteristics of the aboveground parts of the plants when using the full dose of water (100%) than the dose of water reduced by half (50%).
The microbiological analysis of the soil showed that the microbially enriched mineral fertilizers Polifoska 6 and Fos Dar 40 (with the addition of beneficial Bacillus bacteria: Bacillus sp., Bacillus amyloliquefaciens and Paenibacillus polymyxa), and Urea at 100% applied together with filamentous fungi (Paecilomyces lilacinus, Aspergillus niger) had a favourable effect on increasing the numbers of beneficial microorganisms in the rhizosphere soil of ‘Marmolada’ strawberry plants.

The intensive development of the poultry industry is associated with the problem of waste management and creates a number of problems. Promising is the biological method using microorganisms. There are many different microorganisms in manure, some of which are “useful”, as they are actively involved in the decomposition of organic substances. At the same time, manure is a source of transmission of a large number of pathogens of animals and humans (according to WHO). Therefore, it is important to develop biotechnological processes for the disposal of organic waste, ensuring the organization of effective, waste-free and environmental technologies for the bioconversion of manure and litter. We conducted a screening of a large number of microorganisms from various systematic groups for the ability to assimilate organic substances, to show enzymatic activity. Microorganisms are also tested for the ability to show bactericidal and bacteriostatic activity, antiparasitic activity. As a result, active strains of microorganisms were selected, from which effective consortia were formed. These consortia are recommended for processing poultry manure to further use the compost as a bio-fertilizer. Such compost contains a sufficient amount of basic mineral substances, increases the microbial mass of the soil itself and increases the respiration of the soil. Another direction of use of the substrate obtained by us is its burning, since poultry manure has a high calorific value, and the ash obtained by burning is a complex fertilizer with a high nutrient content.

Professional experience of prof. Solarska includes, among others, development of organic hops production technology, development of agrotechnical methods for control of hop Verticillium wilt, detection of pathogenic fungi, viruses and viroids in plants by molecular methods, obtaining of hops free from viruses and viroids, development of cereal, fruits and vegetables cultivation technology in the organic system, research on the effectiveness of natural plant protection products, determination of the quality of organic cereals and their products in terms of content of mycotoxins, estimation of biological and chemical products efficacy against pests, weeds and diseases of different crops for registration aims. Professor received international awards and national awards, among others, for his scientific merits: the PAN award for outstanding scientific achievements in the field of commercialization of research results, twice the Minister of Agriculture and Rural Development award for the development and dissemination of organic hop cultivation technologies and new bioproducts. These studies concerned the evaluation of the effectiveness of probiotic microorganisms and plant extracts in control of diseases and pests of this plant, as well as organic fertilizers and basalt powder in enriching the soil with organic matter and improving the quality of hops. Under her supervision, 3 doctoral thesis was made. Currently she is scientific supervisor of the 3 PhD students. The subject of these doctoral thesis concerns toxinogenic fungi of the genus Fusarium, yeasts inhibiting fungi of the genus Fusarium, as well as a comparison of the microbiome of plants from organic and conventional farming.
Microorganisms play an important role in plant health protection. Some of them are known as producers of bioactive substances such as vitamins, hormones, enzymes, antioxidants and antibiotics that can directly or indirectly enhance the growth and protection of plants. The use of microorganisms in consortia allows their better survival in any environment compared to single-species preparations, due to their synergism and the creation of a biofilm that is more effective for consortia with more efficient metabolism and more resistant to oxidative stress, as well as for toxic factors. Beneficial microorganisms that increase growth and protect plants can be added to the soil to improve the health of plants. The reason for this phenomenon is the close dependence of plants on their microbiome. By gaining better control over these relationships, pest growth can be reduced and the ecosystem can be more stable. Also fermented plant extracts that enhance plant defense mechanisms or directly toxic effects are used to increase the effectiveness of microorganisms in plant protection.
