Abstrakt
A deficiency of carbonate material in soil profiles necessitates the liming of agricultural
soils, especially in southern Estonia, where soil acidity significantly influences
agricultural productivity. Liming is a well-established practice for reducing soil acidity
and improving plant growing conditions. The aim of this study was to evaluate the
effectiveness of milled limestone produced by Corestone Agri OÜ in improving the
properties of acidic soils. A pot experiment was conducted growing rapeseed (Brassica
napus subsp. napus) plants on four acidic soils. The lime fertilizer was applied at two
rates, corresponding to 50% and 100% of the calculated lime requirement. Soil macronutrient
contents were analysed before the experiment and at the end of the trial. The results
showed that Corestone lime fertilizer increased soil pH and enhanced calcium and
magnesium concentrations, including the Ca:Mg ratio. However, it had a negative effect
on soil potassium content. Rapeseed biomass generally increased following the use of
lime fertilizer, although nutrient contents in the plants varied. The study demonstrated
the potential of Corestone lime fertilizer to improve acidic soils, while also highlights
the need for further research on micronutrient availability and nutrient balance in plant
nutrition.
