In Lithuania, decades of regular soil liming ceased in 1990. At present, ∼18.7% of Lithuanian agricultural land is acidic and ∼1 million ha are at risk of chemical degradation by acidification. Intrasite observations of long-term experiments (monitored for >30 years) provide valuable datasets that allow evaluation of current soil conditions and enable landscape-scale acidification modelling. Acidic soil properties, soil acidity indices, and their response to liming practices are important issues that must be addressed to maintain the ecological functions of these acidifying agricultural landscapes. An experiment was conducted that involved four liming strategies based on two direct and two indirect lime requirement (LR) determination methods. These strategies are common practices, both generally and in the Baltic States. Results indicate the effect of soil liming on soil acidity indices significantly (P < 0.05) differ between the chosen LR determination method and soil acidity gradations.
