The researchers studied soil samples from the Drawskie Lakeland to understand how different cations important for plant nutrition are distributed in the soil. They found that despite the soil being acidic, it was still able to hold onto important nutrients. Calcium was the most dominant cation, especially in the lower soil layers. Clay-rich horizons contained more calcium and magnesium. The presence of potassium in some soils was likely due to fertilization and mineral weathering. The highest levels of magnesium and calcium were found in specific soil layers, suggesting a mix of different soil processes happening in those areas.
