Options of using Zn - contaminated soil for the production of some agricultural crops

Popis výsledku v původním jazyce

Soil samples were taken from the top (ploughing) layer of soil contaminated with Zn for a long period. In dependence on the source of contamination, Zn contents (estimated in 1 M HCl) were 45 -- 60; 127 -- 131; 186 -- 194 and 263 -- 298 ppm. The effect of increased Zn levels on yields and health status of seeds of winter rape and of ryegrass hay was studied in a vegetation pot trial. The yields of seeds of winter rape increased proportionally to the level of Zn in the soil. The highest yields were obtained with 186 ppm of Zn per 1 kg of soil. A further increase in the level of Zn in the soil resulted in the depression of both seed and straw yields. The content of Zn in seeds increased in dependence on the level of Zn in soil and increased from 50.8 to84.6 ppm. The content of Zn in the straw increased too, viz. from 50.9 to 203.6 ppm. Higher levels of zinc in the soil showed a more marked effect on the Zn content in straw than in seeds. In seeds, the Zn content decreased with the incre
