: This study aimed to evaluate the fertilizing value of rye stillage used in the cultivation of winter triticale cv. ‘Grenado’. The research was performed in 2018 (autumn, before the application of the stillage), 2019, and 2020 (spring and autumn after stillage application) on Luvisoil at the depth levels of 0–20 and 20–40 cm. Each year, the basic soil parameters were analyzed, i.e., pH in 1M KCl, organic carbon (Corg), available phosphorus (P), potassium (K), magnesium (Mg), zinc (Zn), and copper (Cu). Enzymes were also accounted: alkaline phosphatase (AlP), acid phosphatase (AcP), and dehydrogenases (DEH). The use of stillage resulted in a significant increase in the content of P, K, and Mg and the activity of AlP, AcP, and DEH in the soil. It significantly increased the Corg content and did not have a significant effect on pH. The obtained results indicate that the response of the enzymatic activity to the distillery stillage depended on both the sampling season soil and the depth. However, it is necessary to systematically monitor the pH of the soil and at the same time to rationally apply mineral fertilization.
