PB - Zielona Góra: Oficyna Wydawnicza Uniwersytetu Zielonogórskiego N2 - The paper presents the results of analyses of the potassium content marked by means of the Egner-Riehm method (in lactate extract) and a subtotal form (in Aqua Regia), in reclaimed soils of post-mine waste dumps in the Łęknica region. N2 - The quantity of absorbable K in the soils under research was low, amounting on average to 49 mgźkg[-1]. The highest quantity of this form was found on the level of leaf litter (on average 161 mgźkg[-1]), and the quantity decreased with depth. Differences in the quantity of a potassium subtotal form in the analysed material were small, and average value was 1042 mgźkg[-1].
