Please cite as: CHEMIK 2014, 68, 10, 901–904

Biomass is an energy feedstock which, unlike fossil fuels, contributes no additional CO2 amounts to the atmosphere. Carbon dioxide emitted during combustion of biomass is absorbed during the plant growth. The research results show that 1 hectare (ha) of hemp assimilates approximately 2.5 t of CO2. Hemp is characterized by...

The study of molybdenum leaching from soils fertilized with sewage sludge and their composts
BOŻYM M., RAJMUND A.

Please cite as: CHEMIK 2014, 68, 10, 874–879

Changes of molybdenum content in soils fertilized with sewage sludge and composts during lysimeter experiment was researched. Additionally, the mobility of this metal was measured using selected extractants (H2O, 0.1M HCl, 1M HCl). Sewage sludges and composts were characterized by more than twice larger molybdenum content...
