Use of a mixture of mineralized fossil water and probiotic preparations as the main fertilizer on agricultural crops

Summary/Abstract: Purpose. Тhe aim of the work was to investigate the possibilities of using a mixture of mineralized fossil water and probiotic preparations as the main fertilizer on crops.Results. Research on the formation of innovative fertilizers based on biological methods – mineralized fossil water (with application rates of 900–2400 l/ha) and probiotics (100 l/ha, 10% dilution) was carried out during 2016–2021. The technology of complex the use of probiotics 100 l/ha (10% dilution) and mineralized fossil water 900 l/ha, while the yield of winter wheat was 51.3 tons/ha, which is 28.9 % higher than the control. It was found that the best dose of mineralized fossil water in this mixture on corn crops is also 900 l/ha and probiotic 100 l/ha (10% dilution), which made it possible to obtain an average yield increase over the years of research in the amount of 24.3 % compared to the control. This is explained by the fact that at these concentrations of mineralized fossil water and probiotics, favorable conditions are created for the life of a number of soil microorganisms, in particular, the growth and development of microscopic fungi and cellulose-degrading microorganisms that participate in the decomposition of crop residues are stimulated. The number of ammonifying and nitrogen-fixing bacteria when using mineralized fossil water and probiotics increases immediately after application, then during the following months their number equalizes to the control level. The use of mineralized fossil water doses of more than 1200 l/ha leads to a decrease in these groups of bacteria. It was also established that there is no negative effect of the mixture of mineralized fossil water and probiotics on the soil structure when they are applied in certain doses of mineralized fossil water – from 600 to 1200 l/ha, probiotics at a dose of 100 l/ha (10 % dilution). Thus, the obtained results of the conducted research make it possible to further use mixtures of mineralized fossil water and probiotic preparations as the main fertilizer on crops.Scientific novelty. It was determined that the application of probiotic with mineralized fossil water as the main fertilizer in agroecosystems supports the optimization of the soil microbocenosis and formation of sustainable soil function.Practical value. An innovative and ecologically-oriented method of fertilizing agricultural crops based on the application of probiotic and mineralized fossil water is proposed, which allows to increase crops productivity and quality of agricultural products and to improve sustainable functioning of agroecosystems.
