Biyokömür Karıştırma Zonu Toprak Karbondioksit Emisyonu Üzerinde Etkilidir

Abstract

Several factors are effective on soil carbon dioxide emissions caused by agricultural practices; soil organic matter contents, soil moisture and temperature, climatic changes, and tillage techniques are predominant. In recent years, as a CO2 sequestration agent, biochar incorporation becomes a promising approach. Many studies show that biochar reduces soil CO2 emissions; however, incorporation depth is not widely studied. A pot experiment was carried out to determine the effects of the incorporation zone of rose pulp biochar produced at 400 C on carbon dioxide emission. Treatments were Z as without biochar incorporation (control), A, B, and C are the incorporation zone of 0-7, 0-14, and 0-21 cm soil layer. The measurements in the experiment last for about 2 months. Results revealed that mean CO2 emissions for Z, A, B, and C treatments were 0.048, 0.052, 0.064, and 0.076 g m-2h-1, respectively. According to these results, it was determined that the biochar admixed in the C layer caused more soil CO2 emissions, and there was no significant difference between the other treatments (p>0.05). The highest plant biomass development was obtained in the B treatment (p<0.05).
