“…Recent changes in climate towards warming and longer dry seasons have shifted the acid-base balance of soils to some degree (Polovyy et al, 2022). Moreover, the acid-base balance, genetically inherent to soils, is disrupted by agricultural activities such as the introduction of fertilizers and ameliorants and the type of crop rotation (Smaga et al, 2017).…”

Aim. To study acid-base buffering capacity depending on the intensity of different fertilization systems, including lim- ing, with different doses of CaCO3 in a long-term (55 years) stationary experiment on Albic Stagnic Luvisol (light grey forest surface-gleyed soil). This study should serve as a basis for the restoration and protection of fertility and yield and preservation of ecological restorative functions of this soil type. Methods. Field stationary experiment, using monitoring, laboratory-analytical and statistical-mathematical methods. Results. It was found that after 35 years of a seven-field crop rotation the exclusion of the intensive crops of sugar beet, potato and one winter wheat, in combina- tion with low (2.5 time less) mineral fertilization levels, contributed to an increase in resistance to acidification over the next 20 years from 5.53 to 7.48 points (using a 100-point scale) with a simultaneous increase in soil рНКСl from 3.77 to 4.12. Organo-mineral fertilization (N65P68K68 + 10 t manure/ha of crop rotation area) and periodic application of CaCO3 by hydrolytic acidity (6.0 t/ha) and an optimal dose of lime (2.5 t/ha CaCO3) increased pH buffering over these 20 years in a four-field rotation. The general evaluation index of buffering was 21.8–21.9 points, exceeding the virgin soil by 1.9 to 2 points. In the control variants without the use of fertilizers the general evaluation index of buffering was 14.3 ± 0.3, and the coefficient of buffer asymmetry was the highest – 0.646 ± 0.013, which under these conditions indicated the danger of soil losing its ability for self-regulation and self-healing. Conclusions. The resis- tance of Albic Stagnic Luvisol to acidification increased most in the combined application of N65P68K68 and 10 t/ha manure, together with an optimum calculated dose of lime in a 4-year crop rotation. An optimal dose of CaCO3 (2.5 t/ha) and organo-mineral fertilizing system in a 4-year crop rotation improved the soil buffering capacity of the acid shoulder by 2.45 points compared to the mineral fertilization system. To support a determination of acid-buffering effects graphic charts representing pH buffering capacity proved to be useful and could be instrumental in diagnostics and optimization of the acid-base regime for acid forest soils in general.

As climate change and energy crises increase, NPK (nitrogen, phosphorus and potassium) fertilizer supply chains become more volatile. Globally, the Russian attack on Ukraine has caused the cost of gas to rise and fertilizer supplies to decline. This aggression may worsen the energy and wheat resource crisis in global supply chains. As a result of the escalation of hostilities, natural gas, oil, and coal prices have rapidly increased. In the years preceding the conflict, the agricultural sector had already begun to suffer, caused by unprecedented increases in the prices of natural gas and raw materials for the production of fertilizers stemming from Russian manipulation, especially in the gas market. Prior to the growing season, farmers were still unable to afford fertilizer prices. This situation will be exacerbated by the war. We can conclude from our results that European countries and the United States have high wheat production potential. Developed countries have significant nitrogen, phosphorus, and potassium fertilizer resources. Ukraine has a large yield gap, ranging between 4.5 and 7 Mg/ha. Wheat supply crises can be caused by tense geopolitical affairs, including military aggression and economic embargoes. Based on this, we recommend that decision-makers focus on crop quality to increase the country’s own production.
