Abstract:
The number of studies investigating the effect of bio-fertilizers is increasing because of their importance in sustainable agriculture and environmental quality. In our experiments, we measured the effect of different fertilizers on soil respiration. In the present study, we were looking for the cause of unexpected changes in CO2 values while examining Chernozem soil samples. We concluded that CO2 oxidizing microbes or methanotrophs may be present in the soil that periodically consume CO2 . This is unusual for a sample taken from the upper layer of well-ventilated Chernozem soil with optimal moisture content.

Respiration
Energy production in the human body is primarily fueled by oxidation, a process where food molecules are burned by combining with oxygen to produce carbon dioxide and water. This vital metabolic process sustains life, and is supported intricately by the respiratory system.
Structure and Function of the Respiratory System:
The respiratory system is a complex network of structures that includes the nose, oropharynx, larynx, trachea,...
