A pot experiment was carried out in two one-year series to examine the effect of various concentrations of Tytanit (0.001-3.6%) applied once or twice alongside mineral NPK fertilization, on the content of Zn, Li, Ni, Cr, Pb, and Cd in celery (Apium graveolens L. var. dulce Mill. Pers.). The total content of select elements was determined in the solution obtained after dry combustion of celery biomass...
We investigated the influences of fertilization using fresh and composted sewage sludge with the addition of calcium oxide, brown coal ash, straw, and sawdust on the yield and nitrogen content in maize biomass, as well as the values of utilization coefficient. The biomass yields of maize fertilized with only sewage sludge, as well as sludge with brown coal ash and sawdust, were similar. Lower yields...
