The aim of the study was to evaluate the effectiveness of the integrated application of multifunctional microbial biopreparations (in particular Mycofriend, Groundfix, and Ecostern) in compensating for physiological limitations and improving the economic efficiency of winter wheat (Triticum aestivum L., cultivar Patras DSV) under conditions of late, suboptimal sowing (30 October) following soybean.
It was established that biological intensification resulted in a significant acceleration of phenological development (heading occurring 7 days earlier) and an improvement in morphogenesis (a 2–4-fold increase in tillering and a 22% increase in root system development). The applied biopreparation complex ensured a positive transformation of soil nutrition (a significant increase in the content of available phosphorus) and a 3–5-fold increase in soil biological activity. A biocontrol effect was also recorded, manifested in a reduced incidence of fungal diseases (yellow rust and Pyrenophora leaf spot).
The key conclusion is the demonstrated critical role of the biodecomposer (Ecostern) within the complex. In the treatment without this component, the economic effect was negative (–279 UAH/ha), whereas the integrated application (with the biodecomposer) provided a substantial positive economic effect (+1,654.56 UAH/ha), confirming its necessity for converting biological activity into an economic equivalent.
