In the rolling landscapes of Ukraine’s Carpathian region, a quiet revolution is taking place beneath our feet. Researchers at the Institute of Agriculture of Carpathian Region of NAAS are delving into the intricate world of soil biology, seeking to unlock the secrets of sustainable agriculture. At the forefront of this endeavor is lead author A. O. Dubytska, who has been investigating the impact of ecologized fertilizing systems (EFS) on the biological processes in gray forestal soil under winter wheat.
The study, published in the journal ‘Передгірне та гірське землеробство і тваринництво’ (translated as ‘Foothill and Mountain Agriculture and Animal Husbandry’), reveals promising insights into the interplay between fertilizers, soil health, and crop productivity. The research team conducted a three-year experiment (2018–2020) to evaluate the effectiveness of various EFS arrangements based on optimal mineral fertilizer rates (N60P90K90), combined with biostimulators and organic components.
The findings are compelling. Dubytska and her team discovered that the introduction of humus or microbiological fertilizers, in conjunction with mineral fertilizers and biostimulators, significantly enhanced the soil’s enzymatic activity. “The highest increase in destructive ability of corresponding soil hydrolases among the EFSs used was provided by the factor of organic components added to the soil,” Dubytska explains. This translates to a substantial boost in cellulolytic and proteolytic activities, crucial for breaking down organic matter and releasing nutrients for plant uptake.
The research also highlighted a notable trend: the application of humus or microbiological fertilizers led to an increase in dehydrogenase activity, a key indicator of soil health. This enzyme plays a pivotal role in the respiratory processes of microorganisms, contributing to the overall vitality of the soil ecosystem.
The commercial implications of this research are substantial. In an era where sustainable agriculture is paramount, understanding how to optimize soil health can lead to significant improvements in crop yields and long-term productivity. The study found that the integrated application of biostimulators and organic components on a mineral fertilizer background resulted in the highest content of mobile organic matter, translating to a yield increase of 3.00–9.65% for winter wheat.
“This integrated approach was the most effective in improving winter wheat productivity,” Dubytska notes. The findings suggest that by fine-tuning fertilizing systems, farmers can achieve higher yields while simultaneously enhancing soil health, a win-win for both the agricultural sector and the environment.
The research not only sheds light on the immediate benefits of ecologized fertilizing systems but also lays the groundwork for future developments in sustainable agriculture. As Dubytska and her team continue to explore the intricate relationships between soil biology and crop productivity, the agricultural community can look forward to more innovative strategies for improving soil health and ensuring food security.
In the words of Dubytska, “The results obtained make it possible to form separate elements of the scientific foundations necessary for the development of ways and methods of improving the biological state of soils, obtaining high and sustainable crop yields.” This research is a testament to the power of scientific inquiry in driving agricultural innovation and shaping a more sustainable future.
