where EN represents the difference between the measured values of the samples incubated with and without chloroform, and 0.45 is the conversion coefficient of SMBN.
Effect of fertiliser application on SMBC, SMBN, and SMQ
The levels of SMBC, SMBN, and SMQ in response to organic-inorganic combination fertilisers were significantly higher than that with the Cont treatment (P < 0.05).
In this study, SMBC and SMBN were significantly higher after the organic and inorganic fertiliser treatments in relation to the Cont treatment, and were higher after treatment with combined organic-inorganic than after inorganic fertiliser.
The SMBC, SMBN, and SMQ in the soil from different treatments Different letters in the same column indicate significant differences at P < 0.05.
(2015) reproted that in same ecological conditions the SMBC and SMBN were correlated to the physcio-chemical properties of soil and due to this relationship SMB is an important soil quality indicator, especially with respect to land use type.
In this study, the concentrations of SMBC and SMBN, SOC, total N and the relationships between SMB distribution with physico-chemical properties in the 0 to 15 cm and 15 to 30 cm soil layers were compared under different agro-climatic conditions.
Microbial biomass carbon and microbial biomass nitrogen: The SMBC and SMBN were measured by the fumigation-extraction method (Okalebo et al., 1993).
The SMBN and SMBC were determined from same extract.
The SMBN under different land uses of Eutrudepts is given in Table-5.
The land uses effect on SMBN of Hapludolls (Table-6) showed that forest, grass and cultivated lands had SMBN of 49.52, 49.52 and 27.36 mg / Kg, respectively.
Meetings and gatherings for SMBN are scheduled monthly with on-going online and offline workshops and courses.
