“…There are multiple indicators that can be used to assess soil acidification, such as pH, base saturation, aluminum (Al) concentration, the ratio of Al to base cations, and cation exchange capacity (CEC) [53]. In agricultural soils, soil pH is the primary indicator used to evaluate the acidity level of the soil and determine if liming is necessary.…”

The aim of the study was to assess the impact of the specialization of agricultural production on selected parameters of soil health, i.e., soil organic carbon content (SOC), soil acidification, soil nutrient status, i.e., total nitrogen content (NT), available forms of phosphorus, potassium, and magnesium, and microelements content, as well as the content of selected potentially toxic metals (PTMs). For the study, 18 farms located in the Masovian Voivodeship in Central Poland were selected. They were grouped into six types, and each type was represented by three farms. The study included organic farms; farms specializing in: crop, vegetable, poultry, dairy cattle, and pigs production. A total of 144 soil samples were analyzed. The results showed that the specialization of agricultural production and fertilizer management had a significant impact on most of the tested soil health parameters, except SOC and NT content. Despite the high organic fertilizer doses introduced into soils in poultry (170 kg N per hectare as poultry manure) and pig farms (150 kg N per hectare as pig manure), there was no significant influence of these amendments on SOC content. This may indicate low organic carbon sequestration potential in some Polish agricultural soils. Organic farms had the lowest levels of plant nutrients in the tested soil samples, which may limit soil productivity. All the tested soils were strongly acidified, which could restrict both production and regulatory soil functions. Based on the synthetic index of soil fertility (SSFI), vegetable and poultry farms were characterized by very high fertility, while crop, dairy cattle, and pig farms fell into the medium fertility class. Organic farms were in the lowest fertility class. However, the study suggests that the SSFI may not be the best indicator for assessing soil fertility and health; therefore, further research is needed.

“…The impacts of N deposition are known for certain terrestrial habitats, but many still remains uncertain [15] . Critical loads of N has been developed in the framework of the Convention on Long-range Transboundary Air Pollution [15] , [23] . These critical loads are defined as thresholds below which damaging effects on specific habitats do not occur based on the latest scientific knowledge [24] .…”

“…In addition, an appropriate framework of regression model should be selected, suitable for the selected study design. Bayesian change-point regression models have been shown to overcome some difficulties of large spatial variation found in natural habitats by taking into account confounding factors such as climatic variation or different soil types [23] , [27] , allowing a more accurate estimation of the critical load [28] . Therefore, change-point regression models applied in a Bayesian framework are useful statistical tools in estimating critical empirical loads [1] .…”
