Příprava aktivního uhlíkatého sorbentu z odpadní fytomasy s vysokou salinitou
The study presented here solved the problem of very low specific surfaces, which are achieved when using the standard method of physical activation of brown macroalgae (Phaeophyceae) waste. The material consist-ing of crushed thallus residues from the processing of macroalgae for food purposes contained 14.6% of ash, which consisted mostly of Na, K, Mg

Implications of calcium nutrition on the response of Butea monosperma (Fabaceae) to Soil Salinit
Effects of Ca2+ level on the response of germination and seedling growth of Butea monosperma (Lam.) Taub. (Fabaceae) to NaCl salinity in soil were investigated. Salinity significantly retarded the seed germination and seedling growth, but the injurious effects of NaCl on seed germination were ameliorated and seedling growth
