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.
Highlights
The soil can be characterized by physical, chemical and microbiological properties[1,2,3,4]
The quantitative[5,6] and qualitative[7,8] microbiological properties of the soil greatly contribute to the impact analysis of land use[9,10,11], nutrition[12] and soil management[13]
We measured the effect of different chemicals[19,20,21,22] and a bio-fertilizer on soil microbial activity, using both well-established and novel methods under laboratory conditions
Summary
The soil can be characterized by physical, chemical and microbiological properties[1,2,3,4]. The quantitative (microbial biomass, number of bacteria)[5,6] and qualitative (enzymatic activity, soil respiration)[7,8] microbiological properties of the soil greatly contribute to the impact analysis of land use[9,10,11], nutrition[12] and soil management[13]. Research related to the benefits of microbes as biofertilizer has become increasingly important in the agricultural sector. This is due to the possibility of achieving higher crop yields while minimizing negative impact on the environment. We measured the effect of different chemicals[19,20,21,22] and a bio-fertilizer on soil microbial activity, using both well-established and novel methods under laboratory conditions. We present some unexpected results from a setup in which Chernozem soil samples were examined
