Scientific and methodological recommendations “Scientific basis of the evolutionary patterns of functional stability and information support for sustainable fertility management of acidic light-gray forest surface gleyed soils” were prepared (Appendix A). The conducted studies have established that with long-term use in a four-field crop rotation in conditions of acidic light-gray forest superficially gleyed soils of an organo-mineral fertilizer system with the application of one norm of mineral fertilizers (N65Р68К68) per hectare of crop rotation area, 10 tons of manure against the background of liming with a dose of CaCO3 calculated according to the acid-base buffering capacity (2.5 t/ha), the functional stability of the soil ecosystem is optimized to the greatest extent by primarily reducing acidity (pHKCl is 5.54) and the content of mobile aluminum and manganese compounds to harmless values ​​(10.8 and 16.0 mg/kg, respectively), and the improvement of physico-chemical properties occurs, ensuring a high level of crop rotation productivity at the level of 7.23 t/ha of grain units. Studies have shown that the intensive inclusion of light gray forest soil in the farming system without fertilizers and with long-term use of only the mineral fertilizer system are characterized by unfavorable buffering capacity with respect to acid loads, are accompanied by a decrease in acidity (pHKCl 4.35), an increase in ORP along the soil profile, and lead to excessive accumulation of toxic compounds Al (68.4 mg/kg) and Mn (109.4 mg/kg) in the soil, which ultimately poses a risk of the soil losing its self-regulation and self-renewal mechanisms and is accompanied by low yields of cultivated crops and crop rotation productivity in general.
