"The effects of solid and liquid potassium humates on Cd, Zn and Pb contents in shoots and roots of spring wheat were studied in a pot experiment in climabox. Humates were applied into the soils in four doses (0.3; 0.15; 0.075 a 0.015 %). Both types of humates significantly decreased concentrations of heavy metals in shoots, non-significant decrease (with exception of Zn at 0.3 % humate\u00B4s dose) was found in roots. The decrease of metal uptake by plants was observed with increasing treatment with humates. All treatments of solid potassium humate and two highest treatments (0.3 % and 0.15 %) of liquid potassium humate increased dry matter of shoots. The root growth was stimulated by the highest treatments of solid humate (0.3 %). Therefore, the total heavy metal uptake by spring wheat plants in a pot experiment was in averadge equilibrated between the treated variants (data not shown), because the dry matter of plants in variants treated with 0.3 and 0.15 % dose increased.
