AB [EN] Aluminium phytotoxicity is considered the main limiting factor for crop productivity inagricultural acid soils. Liming is a common practice used to improve acidic soil properties, butan appropriate liming material is essential for both agricultural productivity and environmentalsustainability. A long-term field experiment with two liming amendments (dolomitic limestone andlimestone) was developed during 10 years to determine the changes in soil acidity and assess theeffects on crop (rye) yields. Although the adverse effects of the soil acidity conditions were alleviatedwith both amendments tested, dolomitic limestone was the most effective in the short- and long-termperiod. In terms of the saturation of exchange complex, dolomitic limestone had a better efficiency,likely based on its rate of dissolution. No significant changes in soil organic matter and exchangeablepotassium levels between the treatments tested were found. Both liming materials significantlyincreased the rye total biomass, but interestingly, significant correlations were showed betweentissue levels of magnesium and biomass production, but not between the latter and calcium. Theincreases in rye biomass production compared with control soils at the end of the research were thefollowing: dolomitic limestone, 47%, and limestone, 32%. A link between an increase in magnesiumbioavailability and biomass production was found, as well as between magnesium rye content andtotal, spike and stem biomass. Hence, it could conceivably be hypothesized that since magnesium iscrucial for the transport of assimilates from source leaves to sink organs, alleviating its deficiencyleads to avoiding the reducing growth rate of sink organs. Although further investigations are neededto gain a better understanding of liming on the biological, chemical and physical soil properties inthe long term, our research provides support for the conceptual premise that an appropriate selectionof liming material is crucial for the productivity of acid soils.
