The aim of the study was to determine the effect of acetylene block on the emission of nitrous oxide from soils. The study was conducted on three arable soils of Poland: Haplic Podsol - sandy loam, Eu...
Emission of greenhouse gases and soil organic matter balance in different farming systems
organic farming greenhouse gases methane nitrous oxide
2008/11/19
Estimation of the influence of different farming systems on emission of greenhouse gases (methane and nitrous oxide) was the aim of the research. The research was conducted on the basis of a special f...
Plant contribution to methane emission after irrigation of peat soilwith municipal waste water
methane emission irrigation redox potential waste water grass
2008/11/14
The ability of some plants to grow and develop in the soils with limited access to oxygen results not so much from the biochemical differences in their root metabolism, but from the access of oxygen f...
