Spearman’s rank correlation between microbial biomass carbon and nitrogen and gas emissions and chemical factors of cultivated-sugarcane soils.

N = nitrogen as fertilizer; V = vinasse as fertilizer; S = straw blanket; C = control—without any N and V fertilizer; Ctot = total soil carbon; Ntot = total soil nitrogen; OM = organic matterCO2-C and N2O-N emission rates shown in Fig 1Soil chemical results shown in S1 and S2 TablesSignificant levels for the Spearman’s rank coefficients are indicated at the*P **P ***P Spearman’s rank correlation between microbial biomass carbon and nitrogen and gas emissions and chemical factors of cultivated-sugarcane soils.
